Compile time `with` for strict mode JavaScript
[![build status](https://secure.travis-ci.org/ForbesLindesay/with.png)](http://travis-ci.org/ForbesLindesay/with)
[![Dependency Status](https://gemnasium.com/ForbesLindesay/with.png)](https://gemnasium.com/ForbesLindesay/with)
[![NPM version](https://badge.fury.io/js/with.png)](http://badge.fury.io/js/with)
## Installation
$ npm install with
## Usage
```js
var addWith = require('with')
addWith('obj', 'console.log(a)')
// => "var a = obj.a;console.log(a)"
addWith("obj || {}", "console.log(helper(a))", ["helper"])
// => var locals = (obj || {}),a = locals.a;console.log(helper(a))
```
## API
### addWith(obj, src, [exclude], [environments])
The idea is that this is roughly equivallent to:
```js
with (obj) {
src
}
```
There are a few differences though. For starters, it will be assumed that all variables used in `src` come from `obj` so any that don't (e.g. template helpers) need to have their names parsed to `exclude` as an array. If you want to have browser globals available you can pass a collection of `environments`, e.g.
```js
addWith('obj', 'document.createElement(foo)', [], ['reservedVars', 'ecmaIdentifiers', 'nonstandard', 'browser'])
```
The default environment is: `['reservedVars', 'ecmaIdentifiers', 'nonstandard', 'node']`
It also makes everything be declared, so you can always do:
```js
if (foo === undefined)
```
instead of
```js
if (typeof foo === 'undefined')
```
It is also safe to use in strict mode (unlike `with`) and it minifies properly (`with` disables virtually all minification).

UglifyJS 2
==========
[![Build Status](https://travis-ci.org/mishoo/UglifyJS2.png)](https://travis-ci.org/mishoo/UglifyJS2)
UglifyJS is a JavaScript parser, minifier, compressor or beautifier toolkit.
This page documents the command line utility. For
[API and internals documentation see my website](http://lisperator.net/uglifyjs/).
There's also an
[in-browser online demo](http://lisperator.net/uglifyjs/#demo) (for Firefox,
Chrome and probably Safari).
Install
-------
First make sure you have installed the latest version of [node.js](http://nodejs.org/)
(You may need to restart your computer after this step).
From NPM for use as a command line app:
npm install uglify-js -g
From NPM for programmatic use:
npm install uglify-js
From Git:
git clone git://github.com/mishoo/UglifyJS2.git
cd UglifyJS2
npm link .
Usage
-----
uglifyjs [input files] [options]
UglifyJS2 can take multiple input files. It's recommended that you pass the
input files first, then pass the options. UglifyJS will parse input files
in sequence and apply any compression options. The files are parsed in the
same global scope, that is, a reference from a file to some
variable/function declared in another file will be matched properly.
If you want to read from STDIN instead, pass a single dash instead of input
files.
The available options are:
```
--source-map Specify an output file where to generate source map.
[string]
--source-map-root The path to the original source to be included in the
source map. [string]
--source-map-url The path to the source map to be added in //#
sourceMappingURL. Defaults to the value passed with
--source-map. [string]
--in-source-map Input source map, useful if you're compressing JS that was
generated from some other original code.
--screw-ie8 Pass this flag if you don't care about full compliance
with Internet Explorer 6-8 quirks (by default UglifyJS
will try to be IE-proof). [boolean]
--expr Parse a single expression, rather than a program (for
parsing JSON) [boolean]
-p, --prefix Skip prefix for original filenames that appear in source
maps. For example -p 3 will drop 3 directories from file
names and ensure they are relative paths. You can also
specify -p relative, which will make UglifyJS figure out
itself the relative paths between original sources, the
source map and the output file. [string]
-o, --output Output file (default STDOUT).
-b, --beautify Beautify output/specify output options. [string]
-m, --mangle Mangle names/pass mangler options. [string]
-r, --reserved Reserved names to exclude from mangling.
-c, --compress Enable compressor/pass compressor options. Pass options
like -c hoist_vars=false,if_return=false. Use -c with no
argument to use the default compression options. [string]
-d, --define Global definitions [string]
-e, --enclose Embed everything in a big function, with a configurable
parameter/argument list. [string]
--comments Preserve copyright comments in the output. By default this
works like Google Closure, keeping JSDoc-style comments
that contain "@license" or "@preserve". You can optionally
pass one of the following arguments to this flag:
- "all" to keep all comments
- a valid JS regexp (needs to start with a slash) to keep
only comments that match.
Note that currently not *all* comments can be kept when
compression is on, because of dead code removal or
cascading statements into sequences. [string]
--stats Display operations run time on STDERR. [boolean]
--acorn Use Acorn for parsing. [boolean]
--spidermonkey Assume input files are SpiderMonkey AST format (as JSON).
[boolean]
--self Build itself (UglifyJS2) as a library (implies
--wrap=UglifyJS --export-all) [boolean]
--wrap Embed everything in a big function, making the “exports”
and “global” variables available. You need to pass an
argument to this option to specify the name that your
module will take when included in, say, a browser.
[string]
--export-all Only used when --wrap, this tells UglifyJS to add code to
automatically export all globals. [boolean]
--lint Display some scope warnings [boolean]
-v, --verbose Verbose [boolean]
-V, --version Print version number and exit. [boolean]
```
Specify `--output` (`-o`) to declare the output file. Otherwise the output
goes to STDOUT.
## Source map options
UglifyJS2 can generate a source map file, which is highly useful for
debugging your compressed JavaScript. To get a source map, pass
`--source-map output.js.map` (full path to the file where you want the
source map dumped).
Additionally you might need `--source-map-root` to pass the URL where the
original files can be found. In case you are passing full paths to input
files to UglifyJS, you can use `--prefix` (`-p`) to specify the number of
directories to drop from the path prefix when declaring files in the source
map.
For example:
uglifyjs /home/doe/work/foo/src/js/file1.js \
/home/doe/work/foo/src/js/file2.js \
-o foo.min.js \
--source-map foo.min.js.map \
--source-map-root http://foo.com/src \
-p 5 -c -m
The above will compress and mangle `file1.js` and `file2.js`, will drop the
output in `foo.min.js` and the source map in `foo.min.js.map`. The source
mapping will refer to `http://foo.com/src/js/file1.js` and
`http://foo.com/src/js/file2.js` (in fact it will list `http://foo.com/src`
as the source map root, and the original files as `js/file1.js` and
`js/file2.js`).
### Composed source map
When you're compressing JS code that was output by a compiler such as
CoffeeScript, mapping to the JS code won't be too helpful. Instead, you'd
like to map back to the original code (i.e. CoffeeScript). UglifyJS has an
option to take an input source map. Assuming you have a mapping from
CoffeeScript → compiled JS, UglifyJS can generate a map from CoffeeScript →
compressed JS by mapping every token in the compiled JS to its original
location.
To use this feature you need to pass `--in-source-map
/path/to/input/source.map`. Normally the input source map should also point
to the file containing the generated JS, so if that's correct you can omit
input files from the command line.
## Mangler options
To enable the mangler you need to pass `--mangle` (`-m`). The following
(comma-separated) options are supported:
- `sort` — to assign shorter names to most frequently used variables. This
saves a few hundred bytes on jQuery before gzip, but the output is
_bigger_ after gzip (and seems to happen for other libraries I tried it
on) therefore it's not enabled by default.
- `toplevel` — mangle names declared in the toplevel scope (disabled by
default).
- `eval` — mangle names visible in scopes where `eval` or `when` are used
(disabled by default).
When mangling is enabled but you want to prevent certain names from being
mangled, you can declare those names with `--reserved` (`-r`) — pass a
comma-separated list of names. For example:
uglifyjs ... -m -r '$,require,exports'
to prevent the `require`, `exports` and `$` names from being changed.
## Compressor options
You need to pass `--compress` (`-c`) to enable the compressor. Optionally
you can pass a comma-separated list of options. Options are in the form
`foo=bar`, or just `foo` (the latter implies a boolean option that you want
to set `true`; it's effectively a shortcut for `foo=true`).
- `sequences` -- join consecutive simple statements using the comma operator
- `properties` -- rewrite property access using the dot notation, for
example `foo["bar"] → foo.bar`
- `dead_code` -- remove unreachable code
- `drop_debugger` -- remove `debugger;` statements
- `unsafe` (default: false) -- apply "unsafe" transformations (discussion below)
- `conditionals` -- apply optimizations for `if`-s and conditional
expressions
- `comparisons` -- apply certain optimizations to binary nodes, for example:
`!(a <= b) → a > b` (only when `unsafe`), attempts to negate binary nodes,
e.g. `a = !b && !c && !d && !e → a=!(b||c||d||e)` etc.
- `evaluate` -- attempt to evaluate constant expressions
- `booleans` -- various optimizations for boolean context, for example `!!a
? b : c → a ? b : c`
- `loops` -- optimizations for `do`, `while` and `for` loops when we can
statically determine the condition
- `unused` -- drop unreferenced functions and variables
- `hoist_funs` -- hoist function declarations
- `hoist_vars` (default: false) -- hoist `var` declarations (this is `false`
by default because it seems to increase the size of the output in general)
- `if_return` -- optimizations for if/return and if/continue
- `join_vars` -- join consecutive `var` statements
- `cascade` -- small optimization for sequences, transform `x, x` into `x`
and `x = something(), x` into `x = something()`
- `warnings` -- display warnings when dropping unreachable code or unused
declarations etc.
- `negate_iife` -- negate "Immediately-Called Function Expressions"
where the return value is discarded, to avoid the parens that the
code generator would insert.
### The `unsafe` option
It enables some transformations that *might* break code logic in certain
contrived cases, but should be fine for most code. You might want to try it
on your own code, it should reduce the minified size. Here's what happens
when this flag is on:
- `new Array(1, 2, 3)` or `Array(1, 2, 3)` → `[1, 2, 3 ]`
- `new Object()` → `{}`
- `String(exp)` or `exp.toString()` → `"" + exp`
- `new Object/RegExp/Function/Error/Array (...)` → we discard the `new`
- `typeof foo == "undefined"` → `foo === void 0`
- `void 0` → `"undefined"` (if there is a variable named "undefined" in
scope; we do it because the variable name will be mangled, typically
reduced to a single character).
### Conditional compilation
You can use the `--define` (`-d`) switch in order to declare global
variables that UglifyJS will assume to be constants (unless defined in
scope). For example if you pass `--define DEBUG=false` then, coupled with
dead code removal UglifyJS will discard the following from the output:
```javascript
if (DEBUG) {
console.log("debug stuff");
}
```
UglifyJS will warn about the condition being always false and about dropping
unreachable code; for now there is no option to turn off only this specific
warning, you can pass `warnings=false` to turn off *all* warnings.
Another way of doing that is to declare your globals as constants in a
separate file and include it into the build. For example you can have a
`build/defines.js` file with the following:
```javascript
const DEBUG = false;
const PRODUCTION = true;
// etc.
```
and build your code like this:
uglifyjs build/defines.js js/foo.js js/bar.js... -c
UglifyJS will notice the constants and, since they cannot be altered, it
will evaluate references to them to the value itself and drop unreachable
code as usual. The possible downside of this approach is that the build
will contain the `const` declarations.
<a name="codegen-options"></a>
## Beautifier options
The code generator tries to output shortest code possible by default. In
case you want beautified output, pass `--beautify` (`-b`). Optionally you
can pass additional arguments that control the code output:
- `beautify` (default `true`) -- whether to actually beautify the output.
Passing `-b` will set this to true, but you might need to pass `-b` even
when you want to generate minified code, in order to specify additional
arguments, so you can use `-b beautify=false` to override it.
- `indent-level` (default 4)
- `indent-start` (default 0) -- prefix all lines by that many spaces
- `quote-keys` (default `false`) -- pass `true` to quote all keys in literal
objects
- `space-colon` (default `true`) -- insert a space after the colon signs
- `ascii-only` (default `false`) -- escape Unicode characters in strings and
regexps
- `inline-script` (default `false`) -- escape the slash in occurrences of
`</script` in strings
- `width` (default 80) -- only takes effect when beautification is on, this
specifies an (orientative) line width that the beautifier will try to
obey. It refers to the width of the line text (excluding indentation).
It doesn't work very well currently, but it does make the code generated
by UglifyJS more readable.
- `max-line-len` (default 32000) -- maximum line length (for uglified code)
- `bracketize` (default `false`) -- always insert brackets in `if`, `for`,
`do`, `while` or `with` statements, even if their body is a single
statement.
- `semicolons` (default `true`) -- separate statements with semicolons. If
you pass `false` then whenever possible we will use a newline instead of a
semicolon, leading to more readable output of uglified code (size before
gzip could be smaller; size after gzip insignificantly larger).
### Keeping copyright notices or other comments
You can pass `--comments` to retain certain comments in the output. By
default it will keep JSDoc-style comments that contain "@preserve",
"@license" or "@cc_on" (conditional compilation for IE). You can pass
`--comments all` to keep all the comments, or a valid JavaScript regexp to
keep only comments that match this regexp. For example `--comments
'/foo|bar/'` will keep only comments that contain "foo" or "bar".
Note, however, that there might be situations where comments are lost. For
example:
```javascript
function f() {
/** @preserve Foo Bar */
function g() {
// this function is never called
}
return something();
}
```
Even though it has "@preserve", the comment will be lost because the inner
function `g` (which is the AST node to which the comment is attached to) is
discarded by the compressor as not referenced.
The safest comments where to place copyright information (or other info that
needs to be kept in the output) are comments attached to toplevel nodes.
## Support for the SpiderMonkey AST
UglifyJS2 has its own abstract syntax tree format; for
[practical reasons](http://lisperator.net/blog/uglifyjs-why-not-switching-to-spidermonkey-ast/)
we can't easily change to using the SpiderMonkey AST internally. However,
UglifyJS now has a converter which can import a SpiderMonkey AST.
For example [Acorn][acorn] is a super-fast parser that produces a
SpiderMonkey AST. It has a small CLI utility that parses one file and dumps
the AST in JSON on the standard output. To use UglifyJS to mangle and
compress that:
acorn file.js | uglifyjs --spidermonkey -m -c
The `--spidermonkey` option tells UglifyJS that all input files are not
JavaScript, but JS code described in SpiderMonkey AST in JSON. Therefore we
don't use our own parser in this case, but just transform that AST into our
internal AST.
### Use Acorn for parsing
More for fun, I added the `--acorn` option which will use Acorn to do all
the parsing. If you pass this option, UglifyJS will `require("acorn")`.
Acorn is really fast (e.g. 250ms instead of 380ms on some 650K code), but
converting the SpiderMonkey tree that Acorn produces takes another 150ms so
in total it's a bit more than just using UglifyJS's own parser.
API Reference
-------------
Assuming installation via NPM, you can load UglifyJS in your application
like this:
```javascript
var UglifyJS = require("uglify-js");
```
It exports a lot of names, but I'll discuss here the basics that are needed
for parsing, mangling and compressing a piece of code. The sequence is (1)
parse, (2) compress, (3) mangle, (4) generate output code.
### The simple way
There's a single toplevel function which combines all the steps. If you
don't need additional customization, you might want to go with `minify`.
Example:
```javascript
var result = UglifyJS.minify("/path/to/file.js");
console.log(result.code); // minified output
// if you need to pass code instead of file name
var result = UglifyJS.minify("var b = function () {};", {fromString: true});
```
You can also compress multiple files:
```javascript
var result = UglifyJS.minify([ "file1.js", "file2.js", "file3.js" ]);
console.log(result.code);
```
To generate a source map:
```javascript
var result = UglifyJS.minify([ "file1.js", "file2.js", "file3.js" ], {
outSourceMap: "out.js.map"
});
console.log(result.code); // minified output
console.log(result.map);
```
Note that the source map is not saved in a file, it's just returned in
`result.map`. The value passed for `outSourceMap` is only used to set the
`file` attribute in the source map (see [the spec][sm-spec]).
You can also specify sourceRoot property to be included in source map:
```javascript
var result = UglifyJS.minify([ "file1.js", "file2.js", "file3.js" ], {
outSourceMap: "out.js.map",
sourceRoot: "http://example.com/src"
});
```
If you're compressing compiled JavaScript and have a source map for it, you
can use the `inSourceMap` argument:
```javascript
var result = UglifyJS.minify("compiled.js", {
inSourceMap: "compiled.js.map",
outSourceMap: "minified.js.map"
});
// same as before, it returns `code` and `map`
```
The `inSourceMap` is only used if you also request `outSourceMap` (it makes
no sense otherwise).
Other options:
- `warnings` (default `false`) — pass `true` to display compressor warnings.
- `fromString` (default `false`) — if you pass `true` then you can pass
JavaScript source code, rather than file names.
- `mangle` — pass `false` to skip mangling names.
- `output` (default `null`) — pass an object if you wish to specify
additional [output options][codegen]. The defaults are optimized
for best compression.
- `compress` (default `{}`) — pass `false` to skip compressing entirely.
Pass an object to specify custom [compressor options][compressor].
We could add more options to `UglifyJS.minify` — if you need additional
functionality please suggest!
### The hard way
Following there's more detailed API info, in case the `minify` function is
too simple for your needs.
#### The parser
```javascript
var toplevel_ast = UglifyJS.parse(code, options);
```
`options` is optional and if present it must be an object. The following
properties are available:
- `strict` — disable automatic semicolon insertion and support for trailing
comma in arrays and objects
- `filename` — the name of the file where this code is coming from
- `toplevel` — a `toplevel` node (as returned by a previous invocation of
`parse`)
The last two options are useful when you'd like to minify multiple files and
get a single file as the output and a proper source map. Our CLI tool does
something like this:
```javascript
var toplevel = null;
files.forEach(function(file){
var code = fs.readFileSync(file);
toplevel = UglifyJS.parse(code, {
filename: file,
toplevel: toplevel
});
});
```
After this, we have in `toplevel` a big AST containing all our files, with
each token having proper information about where it came from.
#### Scope information
UglifyJS contains a scope analyzer that you need to call manually before
compressing or mangling. Basically it augments various nodes in the AST
with information about where is a name defined, how many times is a name
referenced, if it is a global or not, if a function is using `eval` or the
`with` statement etc. I will discuss this some place else, for now what's
important to know is that you need to call the following before doing
anything with the tree:
```javascript
toplevel.figure_out_scope()
```
#### Compression
Like this:
```javascript
var compressor = UglifyJS.Compressor(options);
var compressed_ast = toplevel.transform(compressor);
```
The `options` can be missing. Available options are discussed above in
“Compressor options”. Defaults should lead to best compression in most
scripts.
The compressor is destructive, so don't rely that `toplevel` remains the
original tree.
#### Mangling
After compression it is a good idea to call again `figure_out_scope` (since
the compressor might drop unused variables / unreachable code and this might
change the number of identifiers or their position). Optionally, you can
call a trick that helps after Gzip (counting character frequency in
non-mangleable words). Example:
```javascript
compressed_ast.figure_out_scope();
compressed_ast.compute_char_frequency();
compressed_ast.mangle_names();
```
#### Generating output
AST nodes have a `print` method that takes an output stream. Essentially,
to generate code you do this:
```javascript
var stream = UglifyJS.OutputStream(options);
compressed_ast.print(stream);
var code = stream.toString(); // this is your minified code
```
or, for a shortcut you can do:
```javascript
var code = compressed_ast.print_to_string(options);
```
As usual, `options` is optional. The output stream accepts a lot of otions,
most of them documented above in section “Beautifier options”. The two
which we care about here are `source_map` and `comments`.
#### Keeping comments in the output
In order to keep certain comments in the output you need to pass the
`comments` option. Pass a RegExp or a function. If you pass a RegExp, only
those comments whose body matches the regexp will be kept. Note that body
means without the initial `//` or `/*`. If you pass a function, it will be
called for every comment in the tree and will receive two arguments: the
node that the comment is attached to, and the comment token itself.
The comment token has these properties:
- `type`: "comment1" for single-line comments or "comment2" for multi-line
comments
- `value`: the comment body
- `pos` and `endpos`: the start/end positions (zero-based indexes) in the
original code where this comment appears
- `line` and `col`: the line and column where this comment appears in the
original code
- `file` — the file name of the original file
- `nlb` — true if there was a newline before this comment in the original
code, or if this comment contains a newline.
Your function should return `true` to keep the comment, or a falsy value
otherwise.
#### Generating a source mapping
You need to pass the `source_map` argument when calling `print`. It needs
to be a `SourceMap` object (which is a thin wrapper on top of the
[source-map][source-map] library).
Example:
```javascript
var source_map = UglifyJS.SourceMap(source_map_options);
var stream = UglifyJS.OutputStream({
...

```
The `source_map_options` (optional) can contain the following properties:
- `file`: the name of the JavaScript output file that this mapping refers to
- `root`: the `sourceRoot` property (see the [spec][sm-spec])
- `orig`: the "original source map", handy when you compress generated JS
and want to map the minified output back to the original code where it
came from. It can be simply a string in JSON, or a JSON object containing
the original source map.

"readme": "# Async.js\n\nAsync is a utility module which provides straight-forward, powerful functions\nfor working with asynchronous JavaScript. Although originally designed for\nuse with [node.js](http://nodejs.org), it can also be used directly in the\nbrowser. Also supports [component](https://github.com/component/component).\n\nAsync provides around 20 functions that include the usual 'functional'\nsuspects (map, reduce, filter, each…) as well as some common patterns\nfor asynchronous control flow (parallel, series, waterfall…). All these\nfunctions assume you follow the node.js convention of providing a single\ncallback as the last argument of your async function.\n\n\n## Quick Examples\n\n```javascript\nasync.map(['file1','file2','file3'], fs.stat, function(err, results){\n // results is now an array of stats for each file\n});\n\nasync.filter(['file1','file2','file3'], fs.exists, function(results){\n // results now equals an array of the existing files\n});\n\nasync.parallel([\n function(){ ... },\n function(){ ... }\n], callback);\n\nasync.series([\n function(){ ... },\n function(){ ... }\n]);\n```\n\nThere are many more functions available so take a look at the docs below for a\nfull list. This module aims to be comprehensive, so if you feel anything is\nmissing please create a GitHub issue for it.\n\n## Common Pitfalls\n\n### Binding a context to an iterator\n\nThis section is really about bind, not about async. If you are wondering how to\nmake async execute your iterators in a given context, or are confused as to why\na method of another library isn't working as an iterator, study this example:\n\n```js\n// Here is a simple object with an (unnecessarily roundabout) squaring method\nvar AsyncSquaringLibrary = {\n squareExponent: 2,\n square: function(number, callback){ \n var result = Math.pow(number, this.squareExponent);\n setTimeout(function(){\n callback(null, result);\n }, 200);\n }\n};\n\nasync.map([1, 2, 3], AsyncSquaringLibrary.square, function(err, result){\n // result is [NaN, NaN, NaN]\n // This fails because the `this.squareExponent` expression in the square\n // function is not evaluated in the context of AsyncSquaringLibrary, and is\n // therefore undefined.\n});\n\nasync.map([1, 2, 3], AsyncSquaringLibrary.square.bind(AsyncSquaringLibrary), function(err, result){\n // result is [1, 4, 9]\n // With the help of bind we can attach a context to the iterator before\n // passing it to async. Now the square function will be executed in its \n // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent`\n // will be as expected.\n});\n```\n\n## Download\n\nThe source is available for download from\n[GitHub](http://github.com/caolan/async).\nAlternatively, you can install using Node Package Manager (npm):\n\n npm install async\n\n__Development:__ [async.js](https://github.com/caolan/async/raw/master/lib/async.js) - 29.6kb Uncompressed\n\n## In the Browser\n\nSo far it's been tested in IE6, IE7, IE8, FF3.6 and Chrome 5. Usage:\n\n```html\n<script type=\"text/javascript\" src=\"async.js\"></script>\n<script type=\"text/javascript\">\n\n async.map(data, asyncProcess, function(err, results){\n alert(results);\n });\n\n</script>\n```\n\n## Documentation\n\n### Collections\n\n* [each](#each)\n* [eachSeries](#eachSeries)\n* [eachLimit](#eachLimit)\n* [map](#map)\n* [mapSeries](#mapSeries)\n* [mapLimit](#mapLimit)\n* [filter](#filter)\n* [filterSeries](#filterSeries)\n* [reject](#reject)\n* [rejectSeries](#rejectSeries)\n* [reduce](#reduce)\n* [reduceRight](#reduceRight)\n* [detect](#detect)\n* [detectSeries](#detectSeries)\n* [sortBy](#sortBy)\n* [some](#some)\n* [every](#every)\n* [concat](#concat)\n* [concatSeries](#concatSeries)\n\n### Control Flow\n\n* [series](#series)\n* [parallel](#parallel)\n* [parallelLimit](#parallellimittasks-limit-callback)\n* [whilst](#whilst)\n* [doWhilst](#doWhilst)\n* [until](#until)\n* [doUntil](#doUntil)\n* [forever](#forever)\n* [waterfall](#waterfall)\n* [compose](#compose)\n* [applyEach](#applyEach)\n* [applyEachSeries](#applyEachSeries)\n* [queue](#queue)\n* [cargo](#cargo)\n* [auto](#auto)\n* [iterator](#iterator)\n* [apply](#apply)\n* [nextTick](#nextTick)\n* [times](#times)\n* [timesSeries](#timesSeries)\n\n### Utils\n\n* [memoize](#memoize)\n* [unmemoize](#unmemoize)\n* [log](#log)\n* [dir](#dir)\n* [noConflict](#noConflict)\n\n\n## Collections\n\n<a name=\"forEach\" />\n<a name=\"each\" />\n### each(arr, iterator, callback)\n\nApplies an iterator function to each item in an array, in parallel.\nThe iterator is called with an item from the list and a callback for when it\nhas finished. If the iterator passes an error to this callback, the main\ncallback for the each function is immediately called with the error.\n\nNote, that since this function applies the iterator to each item in parallel\nthere is no guarantee that the iterator functions will complete in order.\n\n__ArLine truncated

In Praise of Idleness
By Bertrand Russell
[1932]
Like most of my generation, I was brought up on the saying: 'Satan finds some mischief for idle hands to do.' Being a highly virtuous child, I believed all that I was told, and acquired a conscience which has kept me working hard down to the present moment. But although my conscience has controlled my actions, my opinions have undergone a revolution. I think that there is far too much work done in the world, that immense harm is caused by the belief that work is virtuous, and that what needs to be preached in modern industrial countries is quite different from what always has been preached. Everyone knows the story of the traveler in Naples who saw twelve beggars lying in the sun (it was before the days of Mussolini), and offered a lira to the laziest of them. Eleven of them jumped up to claim it, so he gave it to the twelfth. this traveler was on the right lines. But in countries which do not enjoy Mediterranean sunshine idleness is more difficult, and a great public propaganda will be required to inaugurate it. I hope that, after reading the following pages, the leaders of the YMCA will start a campaign to induce good young men to do nothing. If so, I shall not have lived in vain.
Before advancing my own arguments for laziness, I must dispose of one which I cannot accept. Whenever a person who already has enough to live on proposes to engage in some everyday kind of job, such as school-teaching or typing, he or she is told that such conduct takes the bread out of other people's mouths, and is therefore wicked. If this argument were valid, it would only be necessary for us all to be idle in order that we should all have our mouths full of bread. What people who say such things forget is that what a man earns he usually spends, and in spending he gives employment. As long as a man spends his income, he puts just as much bread into people's mouths in spending as he takes out of other people's mouths in earning. The real villain, from this point of view, is the man who saves. If he merely puts his savings in a stocking, like the proverbial French peasant, it is obvious that they do not give employment. If he invests his savings, the matter is less obvious, and different cases arise.
One of the commonest things to do with savings is to lend them to some Government. In view of the fact that the bulk of the public expenditure of most civilized Governments consists in payment for past wars or preparation for future wars, the man who lends his money to a Government is in the same position as the bad men in Shakespeare who hire murderers. The net result of the man's economical habits is to increase the armed forces of the State to which he lends his savings. Obviously it would be better if he spent the money, even if he spent it in drink or gambling.
But, I shall be told, the case is quite different when savings are invested in industrial enterprises. When such enterprises succeed, and produce something useful, this may be conceded. In these days, however, no one will deny that most enterprises fail. That means that a large amount of human labor, which might have been devoted to producing something that could be enjoyed, was expended on producing machines which, when produced, lay idle and did no good to anyone. The man who invests his savings in a concern that goes bankrupt is therefore injuring others as well as himself. If he spent his money, say, in giving parties for his friends, they (we may hope) would get pleasure, and so would all those upon whom he spent money, such as the butcher, the baker, and the bootlegger. But if he spends it (let us say) upon laying down rails for surface card in some place where surface cars turn out not to be wanted, he has diverted a mass of labor into channels where it gives pleasure to no one. Nevertheless, when he becomes poor through failure of his investment he will be regarded as a victim of undeserved misfortune, whereas the gay spendthrift, who has spent his money philanthropically, will be despised as a fool and a frivolous person.
All this is only preliminary. I want to say, in all seriousness, that a great deal of harm is being done in the modern world by belief in the virtuousness of work, and that the road to happiness and prosperity lies in an organized diminution of work.
First of all: what is work? Work is of two kinds: first, altering the position of matter at or near the earth's surface relatively to other such matter; second, telling other people to do so. The first kind is unpleasant and ill paid; the second is pleasant and highly paid. The second kind is capable of indefinite extension: there are not only those who give orders, but those who give advice as to what orders should be given. Usually two opposite kinds of advice are given simultaneously by two organized bodies of men; this is called politics. The skill required for this kind of work is not knowledge of the subjects as to which advice is given, but knowledge of the art of persuasive speaking and writing, i.e. of advertising.
Throughout Europe, though not in America, there is a third class of men, more respected than either of the classes of workers. There are men who, through ownership of land, are able to make others pay for the privilege of being allowed to exist and to work. These landowners are idle, and I might therefore be expected to praise them. Unfortunately, their idleness is only rendered possible by the industry of others; indeed their desire for comfortable idleness is historically the source of the whole gospel of work. The last thing they have ever wished is that others should follow their example.
From the beginning of civilization until the Industrial Revolution, a man could, as a rule, produce by hard work little more than was required for the subsistence of himself and his family, although his wife worked at least as hard as he did, and his children added their labor as soon as they were old enough to do so. The small surplus above bare necessaries was not left to those who produced it, but was appropriated by warriors and priests. In times of famine there was no surplus; the warriors and priests, however, still secured as much as at other times, with the result that many of the workers died of hunger. This system persisted in Russia until 1917 [1], and still persists in the East; in England, in spite of the Industrial Revolution, it remained in full force throughout the Napoleonic wars, and until a hundred years ago, when the new class of manufacturers acquired power. In America, the system came to an end with the Revolution, except in the South, where it persisted until the Civil War. A system which lasted so long and ended so recently has naturally left a profound impress upon men's thoughts and opinions. Much that we take for granted about the desirability of work is derived from this system, and, being pre-industrial, is not adapted to the modern world. Modern technique has made it possible for leisure, within limits, to be not the prerogative of small privileged classes, but a right evenly distributed throughout the community. The morality of work is the morality of slaves, and the modern world has no need of slavery.
It is obvious that, in primitive communities, peasants, left to themselves, would not have parted with the slender surplus upon which the warriors and priests subsisted, but would have either produced less or consumed more. At first, sheer force compelled them to produce and part with the surplus. Gradually, however, it was found possible to induce many of them to accept an ethic according to which it was their duty to work hard, although part of their work went to support others in idleness. By this means the amount of compulsion required was lessened, and the expenses of government were diminished. To this day, 99 per cent of British wage-earners would be genuinely shocked if it were proposed that the King should not have a larger income than a working man. The conception of duty, speaking historically, has been a means used by the holders of power to induce others to live for the interests of their masters rather than for their own. Of course the holders of power conceal this fact from themselves by managing to believe that their interests are identical with the larger interests of humanity. Sometimes this is true; Athenian slave-owners, for instance, employed part of their leisure in making a permanent contribution to civilization which would have been impossible under a just economic system. Leisure is essential to civilization, and in former times leisure for the few was only rendered possible by the labors of the many. But their labors were valuable, not because work is good, but because leisure is good. And with modern technique it would be possible to distribute leisure justly without injury to civilization.
Modern technique has made it possible to diminish enormously the amount of labor required to secure the necessaries of life for everyone. This was made obvious during the war. At that time all the men in the armed forces, and all the men and women engaged in the production of munitions, all the men and women engaged in spying, war propaganda, or Government offices connected with the war, were withdrawn from productive occupations. In spite of this, the general level of well-being among unskilled wage-earners on the side of the Allies was higher than before or since. The significance of this fact was concealed by finance: borrowing made it appear as if the future was nourishing the present. But that, of course, would have been impossible; a man cannot eat a loaf of bread that does not yet exist. The war showed conclusively that, by the scientific organization of production, it is possible to keep modern populations in fair comfort on a small part of the working capacity of the modern world. If, at the end of the war, the scientific organization, which had been created in order to liberate men for fighting and munition work, had been preserved, and the hours of the week had been cut down to four, all would have been well. Instead of that the old chaos was restored, those whose work was demanded were made to work long hours, and the rest were left to starve as unemployed. Why? Because work is a duty, and a man should not receive wages in proportion to what he has produced, but in proportion to his virtue as exemplified by his industry.
This is the morality of the Slave State, applied in circumstances totally unlike those in which it arose. No wonder the result has been disastrous. Let us take an illustration. Suppose that, at a given moment, a certain number of people are engaged in the manufacture of pins. They make as many pins as the world needs, working (say) eight hours a day. Someone makes an invention by which the same number of men can make twice as many pins: pins are already so cheap that hardly any more will be bought at a lower price. In a sensible world, everybody concerned in the manufacturing of pins would take to working four hours instead of eight, and everything else would go on as before. But in the actual world this would be thought demoralizing. The men still work eight hours, there are too many pins, some employers go bankrupt, and half the men previously concerned in making pins are thrown out of work. There is, in the end, just as much leisure as on the other plan, but half the men are totally idle while half are still overworked. In this way, it is insured that the unavoidable leisure shall cause misery all round instead of being a universal source of happiness. Can anything more insane be imagined?
The idea that the poor should have leisure has always been shocking to the rich. In England, in the early nineteenth century, fifteen hours was the ordinary day's work for a man; children sometimes did as much, and very commonly did twelve hours a day. When meddlesome busybodies suggested that perhaps these hours were rather long, they were told that work kept adults from drink and children from mischief. When I was a child, shortly after urban working men had acquired the vote, certain public holidays were established by law, to the great indignation of the upper classes. I remember hearing an old Duchess say: 'What do the poor want with holidays? They ought to work.' People nowadays are less frank, but the sentiment persists, and is the source of much of our economic confusion.
Let us, for a moment, consider the ethics of work frankly, without superstition. Every human being, of necessity, consumes, in the course of his life, a certain amount of the produce of human labor. Assuming, as we may, that labor is on the whole disagreeable, it is unjust that a man should consume more than he produces. Of course he may provide services rather than commodities, like a medical man, for example; but he should provide something in return for his board and lodging. to this extent, the duty of work must be admitted, but to this extent only.
I shall not dwell upon the fact that, in all modern societies outside the USSR, many people escape even this minimum amount of work, namely all those who inherit money and all those who marry money. I do not think the fact that these people are allowed to be idle is nearly so harmful as the fact that wage-earners are expected to overwork or starve.
If the ordinary wage-earner worked four hours a day, there would be enough for everybody and no unemployment -- assuming a certain very moderate amount of sensible organization. This idea shocks the well-to-do, because they are convinced that the poor would not know how to use so much leisure. In America men often work long hours even when they are well off; such men, naturally, are indignant at the idea of leisure for wage-earners, except as the grim punishment of unemployment; in fact, they dislike leisure even for their sons. Oddly enough, while they wish their sons to work so hard as to have no time to be civilized, they do not mind their wives and daughters having no work at all. the snobbish admiration of uselessness, which, in an aristocratic society, extends to both sexes, is, under a plutocracy, confined to women; this, however, does not make it any more in agreement with common sense.
The wise use of leisure, it must be conceded, is a product of civilization and education. A man who has worked long hours all his life will become bored if he becomes suddenly idle. But without a considerable amount of leisure a man is cut off from many of the best things. There is no longer any reason why the bulk of the population should suffer this deprivation; only a foolish asceticism, usually vicarious, makes us continue to insist on work in excessive quantities now that the need no longer exists.
In the new creed which controls the government of Russia, while there is much that is very different from the traditional teaching of the West, there are some things that are quite unchanged. The attitude of the governing classes, and especially of those who conduct educational propaganda, on the subject of the dignity of labor, is almost exactly that which the governing classes of the world have always preached to what were called the 'honest poor'. Industry, sobriety, willingness to work long hours for distant advantages, even submissiveness to authority, all these reappear; moreover authority still represents the will of the Ruler of the Universe, Who, however, is now called by a new name, Dialectical Materialism.
The victory of the proletariat in Russia has some points in common with the victory of the feminists in some other countries. For ages, men had conceded the superior saintliness of women, and had consoled women for their inferiority by maintaining that saintliness is more desirable than power. At last the feminists decided that they would have both, since the pioneers among them believed all that the men had told them about the desirability of virtue, but not what they had told them about the worthlessness of political power. A similar thing has happened in Russia as regards manual work. For ages, the rich and their sycophants have written in praise of 'honest toil', have praised the simple life, have professed a religion which teaches that the poor are much more likely to go to heaven than the rich, and in general have tried to make manual workers believe that there is some special nobility about altering the position of matter in space, just as men tried to make women believe that they derived some special nobility from their sexual enslavement. In Russia, all this teaching about the excellence of manual work has been taken seriously, with the result that the manual worker is more honored than anyone else. What are, in essence, revivalist appeals are made, but not for the old purposes: they are made to secure shock workers for special tasks. Manual work is the ideal which is held before the young, and is the basis of all ethical teaching.
For the present, possibly, this is all to the good. A large country, full of natural resources, awaits development, and has has to be developed with very little use of credit. In these circumstances, hard work is necessary, and is likely to bring a great reward. But what will happen when the point has been reached where everybody could be comfortable without working long hours?
In the West, we have various ways of dealing with this problem. We have no attempt at economic justice, so that a large proportion of the total produce goes to a small minority of the population, many of whom do no work at all. Owing to the absence of any central control over production, we produce hosts of things that are not wanted. We keep a large percentage of the working population idle, because we can dispense with their labor by making the others overwork. When all these methods prove inadequate, we have a war: we cause a number of people to manufacture high explosives, and a number of others to explode them, as if we were children who had just discovered fireworks. By a combination of all these devices we manage, though with difficulty, to keep alive the notion that a great deal of severe manual work must be the lot of the average man.
In Russia, owing to more economic justice and central control over production, the problem will have to be differently solved. the rational solution would be, as soon as the necessaries and elementary comforts can be provided for all, to reduce the hours of labor gradually, allowing a popular vote to decide, at each stage, whether more leisure or more goods were to be preferred. But, having taught the supreme virtue of hard work, it is difficult to see how the authorities can aim at a paradise in which there will be much leisure and little work. It seems more likely that they will find continually fresh schemes, by which present leisure is to be sacrificed to future productivity. I read recently of an ingenious plan put forward by Russian engineers, for making the White Sea and the northern coasts of Siberia warm, by putting a dam across the Kara Sea. An admirable project, but liable to postpone proletarian comfort for a generation, while the nobility of toil is being displayed amid the ice-fields and snowstorms of the Arctic Ocean. This sort of thing, if it happens, will be the result of regarding the virtue of hard work as an end in itself, rather than as a means to a state of affairs in which it is no longer needed.
The fact is that moving matter about, while a certain amount of it is necessary to our existence, is emphatically not one of the ends of human life. If it were, we should have to consider every navvy superior to Shakespeare. We have been misled in this matter by two causes. One is the necessity of keeping the poor contented, which has led the rich, for thousands of years, to preach the dignity of labor, while taking care themselves to remain undignified in this respect. The other is the new pleasure in mechanism, which makes us delight in the astonishingly clever changes that we can produce on the earth's surface. Neither of these motives makes any great appeal to the actual worker. If you ask him what he thinks the best part of his life, he is not likely to say: 'I enjoy manual work because it makes me feel that I am fulfilling man's noblest task, and because I like to think how much man can transform his planet. It is true that my body demands periods of rest, which I have to fill in as best I may, but I am never so happy as when the morning comes and I can return to the toil from which my contentment springs.' I have never heard working men say this sort of thing. They consider work, as it should be considered, a necessary means to a livelihood, and it is from their leisure that they derive whatever happiness they may enjoy.
It will be said that, while a little leisure is pleasant, men would not know how to fill their days if they had only four hours of work out of the twenty-four. In so far as this is true in the modern world, it is a condemnation of our civilization; it would not have been true at any earlier period. There was formerly a capacity for light-heartedness and play which has been to some extent inhibited by the cult of efficiency. The modern man thinks that everything ought to be done for the sake of something else, and never for its own sake. Serious-minded persons, for example, are continually condemning the habit of going to the cinema, and telling us that it leads the young into crime. But all the work that goes to producing a cinema is respectable, because it is work, and because it brings a money profit. The notion that the desirable activities are those that bring a profit has made everything topsy-turvy. The butcher who provides you with meat and the baker who provides you with bread are praiseworthy, because they are making money; but when you enjoy the food they have provided, you are merely frivolous, unless you eat only to get strength for your work. Broadly speaking, it is held that getting money is good and spending money is bad. Seeing that they are two sides of one transaction, this is absurd; one might as well maintain that keys are good, but keyholes are bad. Whatever merit there may be in the production of goods must be entirely derivative from the advantage to be obtained by consuming them. The individual, in our society, works for profit; but the social purpose of his work lies in the consumption of what he produces. It is this divorce between the individual and the social purpose of production that makes it so difficult for men to think clearly in a world in which profit-making is the incentive to industry. We think too much of production, and too little of consumption. One result is that we attach too little importance to enjoyment and simple happiness, and that we do not judge production by the pleasure that it gives to the consumer.
When I suggest that working hours should be reduced to four, I am not meaning to imply that all the remaining time should necessarily be spent in pure frivolity. I mean that four hours' work a day should entitle a man to the necessities and elementary comforts of life, and that the rest of his time should be his to use as he might see fit. It is an essential part of any such social system that education should be carried further than it usually is at present, and should aim, in part, at providing tastes which would enable a man to use leisure intelligently. I am not thinking mainly of the sort of things that would be considered 'highbrow'. Peasant dances have died out except in remote rural areas, but the impulses which caused them to be cultivated must still exist in human nature. The pleasures of urban populations have become mainly passive: seeing cinemas, watching football matches, listening to the radio, and so on. This results from the fact that their active energies are fully taken up with work; if they had more leisure, they would again enjoy pleasures in which they took an active part.
In the past, there was a small leisure class and a larger working class. The leisure class enjoyed advantages for which there was no basis in social justice; this necessarily made it oppressive, limited its sympathies, and caused it to invent theories by which to justify its privileges. These facts greatly diminished its excellence, but in spite of this drawback it contributed nearly the whole of what we call civilization. It cultivated the arts and discovered the sciences; it wrote the books, invented the philosophies, and refined social relations. Even the liberation of the oppressed has usually been inaugurated from above. Without the leisure class, mankind would never have emerged from barbarism.
The method of a leisure class without duties was, however, extraordinarily wasteful. None of the members of the class had to be taught to be industrious, and the class as a whole was not exceptionally intelligent. The class might produce one Darwin, but against him had to be set tens of thousands of country gentlemen who never thought of anything more intelligent than fox-hunting and punishing poachers. At present, the universities are supposed to provide, in a more systematic way, what the leisure class provided accidentally and as a by-product. This is a great improvement, but it has certain drawbacks. University life is so different from life in the world at large that men who live in academic milieu tend to be unaware of the preoccupations and problems of ordinary men and women; moreover their ways of expressing themselves are usually such as to rob their opinions of the influence that they ought to have upon the general public. Another disadvantage is that in universities studies are organized, and the man who thinks of some original line of research is likely to be discouraged. Academic institutions, therefore, useful as they are, are not adequate guardians of the interests of civilization in a world where everyone outside their walls is too busy for unutilitarian pursuits.
In a world where no one is compelled to work more than four hours a day, every person possessed of scientific curiosity will be able to indulge it, and every painter will be able to paint without starving, however excellent his pictures may be. Young writers will not be obliged to draw attention to themselves by sensational pot-boilers, with a view to acquiring the economic independence needed for monumental works, for which, when the time at last comes, they will have lost the taste and capacity. Men who, in their professional work, have become interested in some phase of economics or government, will be able to develop their ideas without the academic detachment that makes the work of university economists often seem lacking in reality. Medical men will have the time to learn about the progress of medicine, teachers will not be exasperatedly struggling to teach by routine methods things which they learnt in their youth, which may, in the interval, have been proved to be untrue.
Above all, there will be happiness and joy of life, instead of frayed nerves, weariness, and dyspepsia. The work exacted will be enough to make leisure delightful, but not enough to produce exhaustion. Since men will not be tired in their spare time, they will not demand only such amusements as are passive and vapid. At least one per cent will probably devote the time not spent in professional work to pursuits of some public importance, and, since they will not depend upon these pursuits for their livelihood, their originality will be unhampered, and there will be no need to conform to the standards set by elderly pundits. But it is not only in these exceptional cases that the advantages of leisure will appear. Ordinary men and women, having the opportunity of a happy life, will become more kindly and less persecuting and less inclined to view others with suspicion. The taste for war will die out, partly for this reason, and partly because it will involve long and severe work for all. Good nature is, of all moral qualities, the one that the world needs most, and good nature is the result of ease and security, not of a life of arduous struggle. Modern methods of production have given us the possibility of ease and security for all; we have chosen, instead, to have overwork for some and starvation for others. Hitherto we have continued to be as energetic as we were before there were machines; in this we have been foolish, but there is no reason to go on being foolish forever.

methods
=======
By itself,
````javascript
require('optimist').argv
`````
will use `process.argv` array to construct the `argv` object.
You can pass in the `process.argv` yourself:
````javascript
require('optimist')([ '-x', '1', '-y', '2' ]).argv
````
or use .parse() to do the same thing:
````javascript
require('optimist').parse([ '-x', '1', '-y', '2' ])
````
The rest of these methods below come in just before the terminating `.argv`.
.alias(key, alias)
------------------
Set key names as equivalent such that updates to a key will propagate to aliases
and vice-versa.
Optionally `.alias()` can take an object that maps keys to aliases.
.default(key, value)
--------------------
Set `argv[key]` to `value` if no option was specified on `process.argv`.
Optionally `.default()` can take an object that maps keys to default values.
.demand(key)
------------
If `key` is a string, show the usage information and exit if `key` wasn't
specified in `process.argv`.
If `key` is a number, demand at least as many non-option arguments, which show
up in `argv._`.
If `key` is an Array, demand each element.
.describe(key, desc)
--------------------
Describe a `key` for the generated usage information.
Optionally `.describe()` can take an object that maps keys to descriptions.
.options(key, opt)
------------------
Instead of chaining together `.alias().demand().default()`, you can specify
keys in `opt` for each of the chainable methods.
For example:
````javascript
var argv = require('optimist')
.options('f', {
alias : 'file',
default : '/etc/passwd',
})
.argv
;
````
is the same as
````javascript
var argv = require('optimist')
.alias('f', 'file')
.default('f', '/etc/passwd')
.argv
;
````
Optionally `.options()` can take an object that maps keys to `opt` parameters.
.usage(message)
---------------
Set a usage message to show which commands to use. Inside `message`, the string
`$0` will get interpolated to the current script name or node command for the
present script similar to how `$0` works in bash or perl.
.check(fn)
----------
Check that certain conditions are met in the provided arguments.
If `fn` throws or returns `false`, show the thrown error, usage information, and
exit.
.boolean(key)
-------------
Interpret `key` as a boolean. If a non-flag option follows `key` in
`process.argv`, that string won't get set as the value of `key`.
If `key` never shows up as a flag in `process.arguments`, `argv[key]` will be
`false`.
If `key` is an Array, interpret all the elements as booleans.
.string(key)
------------
Tell the parser logic not to interpret `key` as a number or boolean.
This can be useful if you need to preserve leading zeros in an input.
If `key` is an Array, interpret all the elements as strings.
.wrap(columns)
--------------
Format usage output to wrap at `columns` many columns.
.help()
-------
Return the generated usage string.
.showHelp(fn=console.error)
---------------------------
Print the usage data using `fn` for printing.
.parse(args)
------------
Parse `args` instead of `process.argv`. Returns the `argv` object.
.argv
-----
Get the arguments as a plain old object.
Arguments without a corresponding flag show up in the `argv._` array.
The script name or node command is available at `argv.$0` similarly to how `$0`
works in bash or perl.
parsing tricks
==============
stop parsing
------------
Use `--` to stop parsing flags and stuff the remainder into `argv._`.
$ node examples/reflect.js -a 1 -b 2 -- -c 3 -d 4
{ _: [ '-c', '3', '-d', '4' ],
'$0': 'node ./examples/reflect.js',
a: 1,
b: 2 }
negate fields
-------------
If you want to explicity set a field to false instead of just leaving it
undefined or to override a default you can do `--no-key`.
$ node examples/reflect.js -a --no-b
{ _: [],
'$0': 'node ./examples/reflect.js',
a: true,
b: false }
numbers
-------
Every argument that looks like a number (`!isNaN(Number(arg))`) is converted to
one. This way you can just `net.createConnection(argv.port)` and you can add
numbers out of `argv` with `+` without having that mean concatenation,
which is super frustrating.
duplicates
----------
If you specify a flag multiple times it will get turned into an array containing
all the values in order.
$ node examples/reflect.js -x 5 -x 8 -x 0
{ _: [],
'$0': 'node ./examples/reflect.js',
x: [ 5, 8, 0 ] }
dot notation
------------
When you use dots (`.`s) in argument names, an implicit object path is assumed.
This lets you organize arguments into nested objects.
$ node examples/reflect.js --foo.bar.baz=33 --foo.quux=5
{ _: [],
'$0': 'node ./examples/reflect.js',
foo: { bar: { baz: 33 }, quux: 5 } }
installation
============
With [npm](http://github.com/isaacs/npm), just do:
npm install optimist
or clone this project on github:
git clone http://github.com/substack/node-optimist.git
To run the tests with [expresso](http://github.com/visionmedia/expresso),
just do:
expresso

# Change Log
## 0.1.31
* Delay parsing the mappings in SourceMapConsumer until queried for a source
location.
* Support Sass source maps (which at the time of writing deviate from the spec
in small ways) in SourceMapConsumer.
## 0.1.30
* Do not join source root with a source, when the source is a data URI.
* Extend the test runner to allow running single specific test files at a time.
* Performance improvements in `SourceNode.prototype.walk` and
`SourceMapConsumer.prototype.eachMapping`.
* Source map browser builds will now work inside Workers.
* Better error messages when attempting to add an invalid mapping to a
`SourceMapGenerator`.
## 0.1.29
* Allow duplicate entries in the `names` and `sources` arrays of source maps
(usually from TypeScript) we are parsing. Fixes github isse 72.
## 0.1.28
* Skip duplicate mappings when creating source maps from SourceNode; github
issue 75.
## 0.1.27
* Don't throw an error when the `file` property is missing in SourceMapConsumer,
we don't use it anyway.
## 0.1.26
* Fix SourceNode.fromStringWithSourceMap for empty maps. Fixes github issue 70.
## 0.1.25
* Make compatible with browserify
## 0.1.24
* Fix issue with absolute paths and `file://` URIs. See
https://bugzilla.mozilla.org/show_bug.cgi?id=885597
## 0.1.23
* Fix issue with absolute paths and sourcesContent, github issue 64.

# Source Map
This is a library to generate and consume the source map format
[described here][format].
This library is written in the Asynchronous Module Definition format, and works
in the following environments:
* Modern Browsers supporting ECMAScript 5 (either after the build, or with an
AMD loader such as RequireJS)
* Inside Firefox (as a JSM file, after the build)
* With NodeJS versions 0.8.X and higher
## Node
$ npm install source-map
## Building from Source (for everywhere else)
Install Node and then run
$ git clone https://fitzgen@github.com/mozilla/source-map.git
$ cd source-map
$ npm link .
Next, run
$ node Makefile.dryice.js
This should spew a bunch of stuff to stdout, and create the following files:
* `dist/source-map.js` - The unminified browser version.
* `dist/source-map.min.js` - The minified browser version.
* `dist/SourceMap.jsm` - The JavaScript Module for inclusion in Firefox source.
## Examples
### Consuming a source map
var rawSourceMap = {
version: 3,
file: 'min.js',
names: ['bar', 'baz', 'n'],
sources: ['one.js', 'two.js'],
sourceRoot: 'http://example.com/www/js/',
mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'
};
var smc = new SourceMapConsumer(rawSourceMap);
console.log(smc.sources);
// [ 'http://example.com/www/js/one.js',
// 'http://example.com/www/js/two.js' ]
console.log(smc.originalPositionFor({
line: 2,
column: 28
}));
// { source: 'http://example.com/www/js/two.js',
// line: 2,
// column: 10,
// name: 'n' }
console.log(smc.generatedPositionFor({
source: 'http://example.com/www/js/two.js',
line: 2,
column: 10
}));
// { line: 2, column: 28 }
smc.eachMapping(function (m) {
// ...
});
### Generating a source map
In depth guide:
[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)
#### With SourceNode (high level API)
function compile(ast) {
switch (ast.type) {
case 'BinaryExpression':
return new SourceNode(
ast.location.line,
ast.location.column,
ast.location.source,
[compile(ast.left), " + ", compile(ast.right)]
);
case 'Literal':
return new SourceNode(
ast.location.line,
ast.location.column,
ast.location.source,
String(ast.value)
);
// ...
default:
throw new Error("Bad AST");
}
}
var ast = parse("40 + 2", "add.js");
console.log(compile(ast).toStringWithSourceMap({
file: 'add.js'
}));
// { code: '40 + 2',
// map: [object SourceMapGenerator] }
#### With SourceMapGenerator (low level API)
var map = new SourceMapGenerator({
file: "source-mapped.js"
});
map.addMapping({
generated: {
line: 10,
column: 35
},
source: "foo.js",
original: {
line: 33,
column: 2
},
name: "christopher"
});
console.log(map.toString());
// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
## API
Get a reference to the module:
// NodeJS
var sourceMap = require('source-map');
// Browser builds
var sourceMap = window.sourceMap;
// Inside Firefox
let sourceMap = {};
Components.utils.import('resource:///modules/devtools/SourceMap.jsm', sourceMap);
### SourceMapConsumer
A SourceMapConsumer instance represents a parsed source map which we can query
for information about the original file positions by giving it a file position
in the generated source.
#### new SourceMapConsumer(rawSourceMap)
The only parameter is the raw source map (either as a string which can be
`JSON.parse`'d, or an object). According to the spec, source maps have the
following attributes:
* `version`: Which version of the source map spec this map is following.
* `sources`: An array of URLs to the original source files.
* `names`: An array of identifiers which can be referrenced by individual
mappings.
* `sourceRoot`: Optional. The URL root from which all sources are relative.
* `sourcesContent`: Optional. An array of contents of the original source files.
* `mappings`: A string of base64 VLQs which contain the actual mappings.
* `file`: The generated filename this source map is associated with.
#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)
Returns the original source, line, and column information for the generated
source's line and column positions provided. The only argument is an object with
the following properties:
* `line`: The line number in the generated source.
* `column`: The column number in the generated source.
and an object is returned with the following properties:
* `source`: The original source file, or null if this information is not
available.
* `line`: The line number in the original source, or null if this information is
not available.
* `column`: The column number in the original source, or null or null if this
information is not available.
* `name`: The original identifier, or null if this information is not available.
#### SourceMapConsumer.prototype.generatedPositionFor(originalPosition)
Returns the generated line and column information for the original source,
line, and column positions provided. The only argument is an object with
the following properties:
* `source`: The filename of the original source.
* `line`: The line number in the original source.
* `column`: The column number in the original source.
and an object is returned with the following properties:
* `line`: The line number in the generated source, or null.
* `column`: The column number in the generated source, or null.
#### SourceMapConsumer.prototype.sourceContentFor(source)
Returns the original source content for the source provided. The only
argument is the URL of the original source file.
#### SourceMapConsumer.prototype.eachMapping(callback, context, order)
Iterate over each mapping between an original source/line/column and a
generated line/column in this source map.
* `callback`: The function that is called with each mapping. Mappings have the
form `{ source, generatedLine, generatedColumn, originalLine, originalColumn,
name }`
* `context`: Optional. If specified, this object will be the value of `this`
every time that `callback` is called.
* `order`: Either `SourceMapConsumer.GENERATED_ORDER` or
`SourceMapConsumer.ORIGINAL_ORDER`. Specifies whether you want to iterate over
the mappings sorted by the generated file's line/column order or the
original's source/line/column order, respectively. Defaults to
`SourceMapConsumer.GENERATED_ORDER`.
### SourceMapGenerator
An instance of the SourceMapGenerator represents a source map which is being
built incrementally.
#### new SourceMapGenerator(startOfSourceMap)
To create a new one, you must pass an object with the following properties:
* `file`: The filename of the generated source that this source map is
associated with.
* `sourceRoot`: An optional root for all relative URLs in this source map.
#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
Creates a new SourceMapGenerator based on a SourceMapConsumer
* `sourceMapConsumer` The SourceMap.
#### SourceMapGenerator.prototype.addMapping(mapping)
Add a single mapping from original source line and column to the generated
source's line and column for this source map being created. The mapping object
should have the following properties:
* `generated`: An object with the generated line and column positions.
* `original`: An object with the original line and column positions.
* `source`: The original source file (relative to the sourceRoot).
* `name`: An optional original token name for this mapping.
#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent)
Set the source content for an original source file.
* `sourceFile` the URL of the original source file.
* `sourceContent` the content of the source file.
#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile])
Applies a SourceMap for a source file to the SourceMap.
Each mapping to the supplied source file is rewritten using the
supplied SourceMap. Note: The resolution for the resulting mappings
is the minimium of this map and the supplied map.
* `sourceMapConsumer`: The SourceMap to be applied.
* `sourceFile`: Optional. The filename of the source file.
If omitted, sourceMapConsumer.file will be used.
#### SourceMapGenerator.prototype.toString()
Renders the source map being generated to a string.
### SourceNode
SourceNodes provide a way to abstract over interpolating and/or concatenating
snippets of generated JavaScript source code, while maintaining the line and
column information associated between those snippets and the original source
code. This is useful as the final intermediate representation a compiler might
use before outputting the generated JS and source map.
#### new SourceNode(line, column, source[, chunk[, name]])
* `line`: The original line number associated with this source node, or null if
it isn't associated with an original line.
* `column`: The original column number associated with this source node, or null
if it isn't associated with an original column.
* `source`: The original source's filename.
* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
below.
* `name`: Optional. The original identifier.
#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer)
Creates a SourceNode from generated code and a SourceMapConsumer.
* `code`: The generated code
* `sourceMapConsumer` The SourceMap for the generated code
#### SourceNode.prototype.add(chunk)
Add a chunk of generated JS to this source node.
* `chunk`: A string snippet of generated JS code, another instance of
`SourceNode`, or an array where each member is one of those things.
#### SourceNode.prototype.prepend(chunk)
Prepend a chunk of generated JS to this source node.
* `chunk`: A string snippet of generated JS code, another instance of
`SourceNode`, or an array where each member is one of those things.
#### SourceNode.prototype.setSourceContent(sourceFile, sourceContent)
Set the source content for a source file. This will be added to the
`SourceMap` in the `sourcesContent` field.
* `sourceFile`: The filename of the source file
* `sourceContent`: The content of the source file
#### SourceNode.prototype.walk(fn)
Walk over the tree of JS snippets in this node and its children. The walking
function is called once for each snippet of JS and is passed that snippet and
the its original associated source's line/column location.
* `fn`: The traversal function.
#### SourceNode.prototype.walkSourceContents(fn)
Walk over the tree of SourceNodes. The walking function is called for each
source file content and is passed the filename and source content.
* `fn`: The traversal function.
#### SourceNode.prototype.join(sep)
Like `Array.prototype.join` except for SourceNodes. Inserts the separator
between each of this source node's children.
* `sep`: The separator.
#### SourceNode.prototype.replaceRight(pattern, replacement)
Call `String.prototype.replace` on the very right-most source snippet. Useful
for trimming whitespace from the end of a source node, etc.
* `pattern`: The pattern to replace.
* `replacement`: The thing to replace the pattern with.
#### SourceNode.prototype.toString()
Return the string representation of this source node. Walks over the tree and
concatenates all the various snippets together to one string.
### SourceNode.prototype.toStringWithSourceMap(startOfSourceMap)
Returns the string representation of this tree of source nodes, plus a
SourceMapGenerator which contains all the mappings between the generated and
original sources.
The arguments are the same as those to `new SourceMapGenerator`.
## Tests
[![Build Status](https://travis-ci.org/mozilla/source-map.png?branch=master)](https://travis-ci.org/mozilla/source-map)
Install NodeJS version 0.8.0 or greater, then run `node test/run-tests.js`.
To add new tests, create a new file named `test/test-<your new test name>.js`
and export your test functions with names that start with "test", for example
exports["test doing the foo bar"] = function (assert, util) {
...
};
The new test will be located automatically when you run the suite.
The `util` argument is the test utility module located at `test/source-map/util`.
The `assert` argument is a cut down version of node's assert module. You have
access to the following assertion functions:
* `doesNotThrow`
* `equal`
* `ok`
* `strictEqual`
* `throws`
(The reason for the restricted set of test functions is because we need the
tests to run inside Firefox's test suite as well and so the assert module is
shimmed in that environment. See `build/assert-shim.js`.)

# amdefine
A module that can be used to implement AMD's define() in Node. This allows you
to code to the AMD API and have the module work in node programs without
requiring those other programs to use AMD.
## Usage
**1)** Update your package.json to indicate amdefine as a dependency:
```javascript
"dependencies": {
"amdefine": ">=0.1.0"
}
```
Then run `npm install` to get amdefine into your project.
**2)** At the top of each module that uses define(), place this code:
```javascript
if (typeof define !== 'function') { var define = require('amdefine')(module) }
```
**Only use these snippets** when loading amdefine. If you preserve the basic structure,
with the braces, it will be stripped out when using the [RequireJS optimizer](#optimizer).
You can add spaces, line breaks and even require amdefine with a local path, but
keep the rest of the structure to get the stripping behavior.
As you may know, because `if` statements in JavaScript don't have their own scope, the var
declaration in the above snippet is made whether the `if` expression is truthy or not. If
RequireJS is loaded then the declaration is superfluous because `define` is already already
declared in the same scope in RequireJS. Fortunately JavaScript handles multiple `var`
declarations of the same variable in the same scope gracefully.
If you want to deliver amdefine.js with your code rather than specifying it as a dependency
with npm, then just download the latest release and refer to it using a relative path:
[Latest Version](https://github.com/jrburke/amdefine/raw/latest/amdefine.js)
### amdefine/intercept
Consider this very experimental.
Instead of pasting the piece of text for the amdefine setup of a `define`
variable in each module you create or consume, you can use `amdefine/intercept`
instead. It will automatically insert the above snippet in each .js file loaded
by Node.
**Warning**: you should only use this if you are creating an application that
is consuming AMD style defined()'d modules that are distributed via npm and want
to run that code in Node.
For library code where you are not sure if it will be used by others in Node or
in the browser, then explicitly depending on amdefine and placing the code
snippet above is suggested path, instead of using `amdefine/intercept`. The
intercept module affects all .js files loaded in the Node app, and it is
inconsiderate to modify global state like that unless you are also controlling
the top level app.
#### Why distribute AMD-style nodes via npm?
npm has a lot of weaknesses for front-end use (installed layout is not great,
should have better support for the `baseUrl + moduleID + '.js' style of loading,
single file JS installs), but some people want a JS package manager and are
willing to live with those constraints. If that is you, but still want to author
in AMD style modules to get dynamic require([]), better direct source usage and
powerful loader plugin support in the browser, then this tool can help.
#### amdefine/intercept usage
Just require it in your top level app module (for example index.js, server.js):
```javascript
require('amdefine/intercept');
```
The module does not return a value, so no need to assign the result to a local
variable.
Then just require() code as you normally would with Node's require(). Any .js
loaded after the intercept require will have the amdefine check injected in
the .js source as it is loaded. It does not modify the source on disk, just
prepends some content to the text of the module as it is loaded by Node.
#### How amdefine/intercept works
It overrides the `Module._extensions['.js']` in Node to automatically prepend
the amdefine snippet above. So, it will affect any .js file loaded by your
app.
## define() usage
It is best if you use the anonymous forms of define() in your module:
```javascript
define(function (require) {
var dependency = require('dependency');
});
```
or
```javascript
define(['dependency'], function (dependency) {
});
```
## RequireJS optimizer integration. <a name="optimizer"></name>
Version 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html)
will have support for stripping the `if (typeof define !== 'function')` check
mentioned above, so you can include this snippet for code that runs in the
browser, but avoid taking the cost of the if() statement once the code is
optimized for deployment.
## Node 0.4 Support
If you want to support Node 0.4, then add `require` as the second parameter to amdefine:
```javascript
//Only if you want Node 0.4. If using 0.5 or later, use the above snippet.
if (typeof define !== 'function') { var define = require('amdefine')(module, require) }
```
## Limitations
### Synchronous vs Asynchronous
amdefine creates a define() function that is callable by your code. It will
execute and trace dependencies and call the factory function *synchronously*,
to keep the behavior in line with Node's synchronous dependency tracing.
The exception: calling AMD's callback-style require() from inside a factory
function. The require callback is called on process.nextTick():
```javascript
define(function (require) {
require(['a'], function(a) {
//'a' is loaded synchronously, but
//this callback is called on process.nextTick().
});
});
```
### Loader Plugins
Loader plugins are supported as long as they call their load() callbacks
synchronously. So ones that do network requests will not work. However plugins
like [text](http://requirejs.org/docs/api.html#text) can load text files locally.
The plugin API's `load.fromText()` is **not supported** in amdefine, so this means
transpiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs)
will not work. This may be fixable, but it is a bit complex, and I do not have
enough node-fu to figure it out yet. See the source for amdefine.js if you want
to get an idea of the issues involved.
## Tests
To run the tests, cd to **tests** and run:
```
node all.js
node all-intercept.js
```

"readme": "# Source Map\n\nThis is a library to generate and consume the source map format\n[described here][format].\n\nThis library is written in the Asynchronous Module Definition format, and works\nin the following environments:\n\n* Modern Browsers supporting ECMAScript 5 (either after the build, or with an\n AMD loader such as RequireJS)\n\n* Inside Firefox (as a JSM file, after the build)\n\n* With NodeJS versions 0.8.X and higher\n\n## Node\n\n $ npm install source-map\n\n## Building from Source (for everywhere else)\n\nInstall Node and then run\n\n $ git clone https://fitzgen@github.com/mozilla/source-map.git\n $ cd source-map\n $ npm link .\n\nNext, run\n\n $ node Makefile.dryice.js\n\nThis should spew a bunch of stuff to stdout, and create the following files:\n\n* `dist/source-map.js` - The unminified browser version.\n\n* `dist/source-map.min.js` - The minified browser version.\n\n* `dist/SourceMap.jsm` - The JavaScript Module for inclusion in Firefox source.\n\n## Examples\n\n### Consuming a source map\n\n var rawSourceMap = {\n version: 3,\n file: 'min.js',\n names: ['bar', 'baz', 'n'],\n sources: ['one.js', 'two.js'],\n sourceRoot: 'http://example.com/www/js/',\n mappings: 'CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA'\n };\n\n var smc = new SourceMapConsumer(rawSourceMap);\n\n console.log(smc.sources);\n // [ 'http://example.com/www/js/one.js',\n // 'http://example.com/www/js/two.js' ]\n\n console.log(smc.originalPositionFor({\n line: 2,\n column: 28\n }));\n // { source: 'http://example.com/www/js/two.js',\n // line: 2,\n // column: 10,\n // name: 'n' }\n\n console.log(smc.generatedPositionFor({\n source: 'http://example.com/www/js/two.js',\n line: 2,\n column: 10\n }));\n // { line: 2, column: 28 }\n\n smc.eachMapping(function (m) {\n // ...\n });\n\n### Generating a source map\n\nIn depth guide:\n[**Compiling to JavaScript, and Debugging with Source Maps**](https://hacks.mozilla.org/2013/05/compiling-to-javascript-and-debugging-with-source-maps/)\n\n#### With SourceNode (high level API)\n\n function compile(ast) {\n switch (ast.type) {\n case 'BinaryExpression':\n return new SourceNode(\n ast.location.line,\n ast.location.column,\n ast.location.source,\n [compile(ast.left), \" + \", compile(ast.right)]\n );\n case 'Literal':\n return new SourceNode(\n ast.location.line,\n ast.location.column,\n ast.location.source,\n String(ast.value)\n );\n // ...\n default:\n throw new Error(\"Bad AST\");\n }\n }\n\n var ast = parse(\"40 + 2\", \"add.js\");\n console.log(compile(ast).toStringWithSourceMap({\n file: 'add.js'\n }));\n // { code: '40 + 2',\n // map: [object SourceMapGenerator] }\n\n#### With SourceMapGenerator (low level API)\n\n var map = new SourceMapGenerator({\n file: \"source-mapped.js\"\n });\n\n map.addMapping({\n generated: {\n line: 10,\n column: 35\n },\n source: \"foo.js\",\n original: {\n line: 33,\n column: 2\n },\n name: \"christopher\"\n });\n\n console.log(map.toString());\n // '{\"version\":3,\"file\":\"source-mapped.js\",\"sources\":[\"foo.js\"],\"names\":[\"christopher\"],\"mappings\":\";;;;;;;;;mCAgCEA\"}'\n\n## API\n\nGet a reference to the module:\n\n // NodeJS\n var sourceMap = require('source-map');\n\n // Browser builds\n var sourceMap = window.sourceMap;\n\n // Inside Firefox\n let sourceMap = {};\n Components.utils.import('resource:///modules/devtools/SourceMap.jsm', sourceMap);\n\n### SourceMapConsumer\n\nA SourceMapConsumer instance represents a parsed source map which we can query\nfor information about the original file positions by giving it a file position\nin the generated source.\n\n#### new SourceMapConsumer(rawSourceMap)\n\nThe only parameter is the raw source map (either as a string which can be\n`JSON.parse`'d, or an object). According to the spec, source maps have the\nfollowing attributes:\n\n* `version`: Which version of the source map spec this map is following.\n\n* `sources`: An array of URLs to the original source files.\n\n* `names`: An array of identifiers which can be referrenced by individual\n mappings.\n\n* `sourceRoot`: Optional. The URL root from which all sources are relative.\n\n* `sourcesContent`: Optional. An array of contents of the original source files.\n\n* `mappings`: A string of base64 VLQs which contain the actual mappings.\n\n* `file`: The generated filename this source map is associated with.\n\n#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition)\n\nReturns the original source, line, and column information for the generated\nsource's line and column positions provided.
