# PostCSS Media Minmax
[![Build Status](https://travis-ci.org/postcss/postcss-media-minmax.svg?branch=master)](https://travis-ci.org/postcss/postcss-media-minmax)

> 写简单优雅的 Media Queries！
Media Queries 中的 `min-width` 和 `max-width` 等属性非常容易混淆，每次看到他们，我都想哭。现在[新的规范](https://drafts.csswg.org/mediaqueries/#mq-range-context)中，可以使用更加直观的 `>=`或`<=` 替代 media queries 中的 min-/max- 前缀。
**V2.1.0 开始支持 `>` 或 `<` 符号。**
这是一个实现 [CSS Media Queries Level 4](http://dev.w3.org/csswg/mediaqueries/) Polyfill 的插件，让你现在就可以使用这些特性，妈妈再也不用担心我记不住了，鹅妹子嘤！
[English](README.md)
-----
![Gif Demo](http://gtms02.alicdn.com/tps/i2/TB1UIjyGVXXXXcCaXXXx274FpXX-877-339.gif)
## 安装
$ npm install postcss-media-minmax
## 快速开始
示例 1：
```js
var fs = require('fs')
var postcss = require('postcss')
var minmax = require('postcss-media-minmax')
var css = fs.readFileSync('input.css', 'utf8')
var output = postcss()
.use(minmax())
.process(css)
.css
console.log('\n====>Output CSS:\n', output)
```
或者只需：
```js
var output = postcss(minmax())
.process(css)
.css
```
input.css：
```css
@media screen and (width >= 500px) and (width <= 1200px) {
.bar {
display: block;
}
}
```
你将得到：
```css
@media screen and (min-width: 500px) and (max-width: 1200px) {
.bar {
display: block;
}
}
```
## CSS 语法
### [语法](http://dev.w3.org/csswg/mediaqueries/#mq-syntax)
```
<mf-range> = <mf-name> [ '<' | '>' ]? '='? <mf-value>
| <mf-value> [ '<' | '>' ]? '='? <mf-name>
| <mf-value> '<' '='? <mf-name> '<' '='? <mf-value>
| <mf-value> '>' '='? <mf-name> '>' '='? <mf-value>
```
![syntax](http://gtms03.alicdn.com/tps/i3/TB1Rje0HXXXXXXeXpXXccZJ0FXX-640-290.png)
PostCSS Media Minmax 目前并没有实现 `200px >= width` 或者 `200px <= width` 这样的语法，因为这样的语法可读性并不不是太好。
## [取值(Values)](http://dev.w3.org/csswg/mediaqueries/#values)
**The special values:**
* [<ratio>](http://dev.w3.org/csswg/mediaqueries/#typedef-ratio)
<ratio> 是一个正（非零非负）的 <integer>（整型）取值，其后跟随0个或多个空白，接着跟随一个斜线（“/”），再跟随0个或多个空白，最后跟随一个正<integer>。
```css
@media screen and (device-aspect-ratio: 16 / 9) {
/* rules */
}
/* equivalent to */
@media screen and (device-aspect-ratio: 16/9) {
/* rules */
}
```
* [<mq-boolean>](http://dev.w3.org/csswg/mediaqueries/#typedef-mq-boolean)
<mq-boolean> 值是一个 0 或 1 的 <integer>（整型）取值。其他任何整数无效。注意， 在 CSS 中 -0 总是等价于 0 的，所以也作为一种有效的 <mq-boolean> 取值。
```css
@media screen and (grid: -0) {
/* rules */
}
/* equivalent to */
@media screen and (grid: 0) {
/* rules */
}
```
## 如何使用
### 简写
示例 1中同一个 Media features name 同时存在 `>=` 和 `<=` 时，可以简写为：
```css
@media screen and (500px <= width <= 1200px) {
.bar {
display: block;
}
}
/* 或者 */
@media screen and (1200px >= width >= 500px) {
.bar {
display: block;
}
}
```
都会得到一样的输出结果：
```css
@media screen and (min-width: 500px) and (max-width: 1200px) {
.bar {
display: block;
}
}
```
**注意**：当 Media features name 在中间的时候，一定要保证两个 `<=` 或 `>=` 的方向一致，否则不会转换。
例如在下面的示例中，width 大于等于 500px 同时又大于等于 1200px，这在语法和逻辑上都是错误的。
```css
@media screen and (1200px <= width >= 500px) {
.bar {
display: block;
}
}
```
### 支持的 Media features name
规范中目前以下属性支持 min-/max 前缀，PostCSS Media Minmax 全部支持自动转换。
* `width`
* `height`
* `device-width`
* `device-height`
* `aspect-ratio`
* `device-aspect-ratio`
* `color`
* `color-index`
* `monochrome`
* `resolution`
### 支持在 `@custom-media` 中使用 & Node Watch
```js
var fs = require('fs')
var chokidar = require('chokidar')
var postcss = require('postcss')
var minmax = require('postcss-media-minmax')
var customMedia = require('postcss-custom-media')
var src = 'input.css'
console.info('Watching…\nModify the input.css and save.')
chokidar.watch(src, {
ignored: /[\/\\]\./,
persistent: true
}).on('all',
function(event, path, stats) {
var css = fs.readFileSync(src, 'utf8')
var output = postcss()
.use(customMedia())
.use(minmax())
.process(css)
.css;
fs.writeFileSync('output.css', output)
})
```
input.css:
```css
@custom-media --foo (width >= 20em) and (width <= 50em);
@custom-media --bar (height >= 300px) and (height <= 600px);
@media (--foo) and (--bar) {
}
```
output.css:
```css
@media (min-width: 20em) and (max-width: 50em) and (min-height: 300px) and (max-height: 600px) {
}
```
### Grunt
```js
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
postcss: {
options: {
processors: [
require('autoprefixer-core')({ browsers: ['> 0%'] }).postcss, //Other plugin
require('postcss-media-minmax')(),
]
},
dist: {
src: ['src/*.css'],
dest: 'build/grunt.css'
}
}
});
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-postcss');
grunt.registerTask('default', ['postcss']);
}
```
### Gulp
```js
var gulp = require('gulp');
var rename = require('gulp-rename');
var postcss = require('gulp-postcss');
var selector = require('postcss-media-minmax')
var autoprefixer = require('autoprefixer-core')
gulp.task('default', function () {
var processors = [
autoprefixer({ browsers: ['> 0%'] }), //Other plugin
minmax()
];
gulp.src('src/*.css')
.pipe(postcss(processors))
.pipe(rename('gulp.css'))
.pipe(gulp.dest('build'))
});
gulp.watch('src/*.css', ['default']);
```

# PostCSS Media Minmax
[![CSS Standard Status](https://cssdb.org/badge/media-query-ranges.svg)](https://cssdb.org/#media-query-ranges)
[![Build Status](https://travis-ci.org/postcss/postcss-media-minmax.svg?branch=master)](https://travis-ci.org/postcss/postcss-media-minmax)

> Writing simple and graceful media queries!
The `min-width`, `max-width` and many other properties of media queries are really confusing. I want to cry every time I see them. But right now according to the new specs, you can use more intuitive `<=` or `>=` to replace the `min-`/`max-` prefixes in media queries.
V2.1.0 began to support `>` or `<` symbol.
This is a polyfill plugin which supports [CSS Media Queries Level 4](https://drafts.csswg.org/mediaqueries/#mq-range-context) and gives you access to the new features right away. Mom will never worry about my study any more. So amazing!

![Gif Demo](https://gtms02.alicdn.com/tps/i2/TB1UIjyGVXXXXcCaXXXx274FpXX-877-339.gif)
## Installation
$ npm install postcss-media-minmax
## Quick Start
Example 1:
```js
var fs = require('fs')
var postcss = require('postcss')
var minmax = require('postcss-media-minmax')
var css = fs.readFileSync('input.css', 'utf8')
var output = postcss()
.use(minmax())
.process(css)
.css
console.log('\n====>Output CSS:\n', output)
```
Or just:
```js
var output = postcss(minmax())
.process(css)
.css
```
input.css:
```css
@media screen and (width >= 500px) and (width <= 1200px) {
.bar {
display: block;
}
}
```
You will get:
```css
@media screen and (min-width: 500px) and (max-width: 1200px) {
.bar {
display: block;
}
}
```
## CSS syntax
### [Syntax](https://drafts.csswg.org/mediaqueries/#mq-range-context)
```
<mf-range> = <mf-name> [ '<' | '>' ]? '='? <mf-value>
| <mf-value> [ '<' | '>' ]? '='? <mf-name>
| <mf-value> '<' '='? <mf-name> '<' '='? <mf-value>
| <mf-value> '>' '='? <mf-name> '>' '='? <mf-value>
```
![syntax](https://gtms03.alicdn.com/tps/i3/TB1Rje0HXXXXXXeXpXXccZJ0FXX-640-290.png)
PostCSS Media Minmax hasn't implemented syntax such as `200px > = width` or `200px < = width` currently because its readability is not good enough yet.
## [Values](https://drafts.csswg.org/mediaqueries/#values)
**The special values:**
* [<ratio>](https://drafts.csswg.org/mediaqueries/#typedef-ratio)
The <ratio> value type is a positive (not zero or negative) <integer> followed by optional whitespace, followed by a solidus ('/'), followed by optional whitespace, followed by a positive <integer>. <ratio>s can be ordered or compared by transforming them into the number obtained by dividing their first <integer> by their second <integer>.
```css
@media screen and (device-aspect-ratio: 16 / 9) {
/* rules */
}
/* equivalent to */
@media screen and (device-aspect-ratio: 16/9) {
/* rules */
}
```
* [<mq-boolean>](https://drafts.csswg.org/mediaqueries/#typedef-mq-boolean)
The <mq-boolean> value type is an <integer> with the value 0 or 1. Any other integer value is invalid. Note that -0 is always equivalent to 0 in CSS, and so is also accepted as a valid <mq-boolean> value.
```css
@media screen and (grid: -0) {
/* rules */
}
/* equivalent to */
@media screen and (grid: 0) {
/* rules */
}
```
## How to use
### Shorthand
In Example 1, if a feature has both `>=` and `<=` logic, it can be written as follows:
```css
@media screen and (500px <= width <= 1200px) {
.bar {
display: block;
}
}
/* Or */
@media screen and (1200px >= width >= 500px) {
.bar {
display: block;
}
}
```
Which will output:
```css
@media screen and (min-width: 500px) and (max-width: 1200px) {
.bar {
display: block;
}
}
```
**Note**: When the media feature name is in the middle, we must ensure that two `<=` or `>=` are in the same direction, otherwise which will not be converted.
E.g. in the example below, `width` is greater than or equal to 500px and is greater than or equal to 1200px, which is the wrong in both grammar and logic.
```css
@media screen and (1200px <= width >= 500px) {
.bar {
display: block;
}
}
```
### Media feature names
The following properties support the `min-`/`max-` prefixes in the specifications at present, and will be automatically converted by PostCSS Media Minmax.
* `width`
* `height`
* `device-width`
* `device-height`
* `aspect-ratio`
* `device-aspect-ratio`
* `color`
* `color-index`
* `monochrome`
* `resolution`
### Using with `@custom-media` & Node Watch
```js
var fs = require('fs')
var chokidar = require('chokidar')
var postcss = require('postcss')
var minmax = require('postcss-media-minmax')
var customMedia = require('postcss-custom-media')
var src = 'input.css'
console.info('Watching…\nModify the input.css and save.')
chokidar.watch(src, {
ignored: /[\/\\]\./,
persistent: true
}).on('all',
function(event, path, stats) {
var css = fs.readFileSync(src, 'utf8')
var output = postcss()
.use(customMedia())
.use(minmax())
.process(css)
.css;
fs.writeFileSync('output.css', output)
})
```
input.css:
```css
@custom-media --foo (width >= 20em) and (width <= 50em);
@custom-media --bar (height >= 300px) and (height <= 600px);
@media (--foo) and (--bar) {
}
```
output.css:
```css
@media (min-width: 20em) and (max-width: 50em) and (min-height: 300px) and (max-height: 600px) {
}
```
### Grunt
```js
module.exports = function(grunt) {
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
postcss: {
options: {
processors: [
require('autoprefixer-core')({ browsers: ['> 0%'] }).postcss, //Other plugin
require('postcss-media-minmax')(),
]
},
dist: {
src: ['src/*.css'],
dest: 'build/grunt.css'
}
}
});
grunt.loadNpmTasks('grunt-contrib-uglify');
grunt.loadNpmTasks('grunt-postcss');
grunt.registerTask('default', ['postcss']);
}
```
### Gulp
```js
var gulp = require('gulp');
var rename = require('gulp-rename');
var postcss = require('gulp-postcss');
var selector = require('postcss-media-minmax')
var autoprefixer = require('autoprefixer-core')
gulp.task('default', function () {
var processors = [
autoprefixer({ browsers: ['> 0%'] }), //Other plugin
minmax()
];
gulp.src('src/*.css')
.pipe(postcss(processors))
.pipe(rename('gulp.css'))
.pipe(gulp.dest('build'))
});
gulp.watch('src/*.css', ['default']);
```

# picocolors
npm install picocolors
A tinier and faster alternative to [nanocolors](https://github.com/ai/nanocolors). Andrey, are you even trying?
```javascript
import pc from "picocolors";
console.log(pc.green(`How are ${pc.italic(`you`)} doing?`));
```
- Up to [2x faster and 2x smaller](#benchmarks) than alternatives
- 3x faster and 10x smaller than `chalk`
- [TypeScript](https://www.typescriptlang.org/) support
- [`NO_COLOR`](https://no-color.org/) friendly
- Node.js v6+ & browsers support
- The same API, but faster, much faster
- No `String.prototype` modifications (anyone still doing it?)
- No dependencies and the smallest `node_modules` footprint

PostCSS is a tool for transforming styles with JS plugins.
These plugins can lint your CSS, support variables and mixins,
transpile future CSS syntax, inline images, and more.
PostCSS is used by industry leaders including Wikipedia, Twitter, Alibaba,
and JetBrains. The [Autoprefixer] PostCSS plugin is one of the most popular
CSS processors.
PostCSS takes a CSS file and provides an API to analyze and modify its rules
(by transforming them into an [Abstract Syntax Tree]).
This API can then be used by [plugins] to do a lot of useful things,
e.g. to find errors automatically insert vendor prefixes.

# Change Log
## 0.5.6
* Fix for regression when people were using numbers as names in source maps. See
#236.
## 0.5.5
* Fix "regression" of unsupported, implementation behavior that half the world
happens to have come to depend on. See #235.
* Fix regression involving function hoisting in SpiderMonkey. See #233.
## 0.5.4
* Large performance improvements to source-map serialization. See #228 and #229.
## 0.5.3
* Do not include unnecessary distribution files. See
commit ef7006f8d1647e0a83fdc60f04f5a7ca54886f86.
## 0.5.2
* Include browser distributions of the library in package.json's `files`. See
issue #212.
## 0.5.1
* Fix latent bugs in IndexedSourceMapConsumer.prototype._parseMappings. See
ff05274becc9e6e1295ed60f3ea090d31d843379.
## 0.5.0
* Node 0.8 is no longer supported.
* Use webpack instead of dryice for bundling.
* Big speedups serializing source maps. See pull request #203.
* Fix a bug with `SourceMapConsumer.prototype.sourceContentFor` and sources that
explicitly start with the source root. See issue #199.
## 0.4.4
* Fix an issue where using a `SourceMapGenerator` after having created a
`SourceMapConsumer` from it via `SourceMapConsumer.fromSourceMap` failed. See
issue #191.
* Fix an issue with where `SourceMapGenerator` would mistakenly consider
different mappings as duplicates of each other and avoid generating them. See
issue #192.
## 0.4.3
* A very large number of performance improvements, particularly when parsing
source maps. Collectively about 75% of time shaved off of the source map
parsing benchmark!
* Fix a bug in `SourceMapConsumer.prototype.allGeneratedPositionsFor` and fuzzy
searching in the presence of a column option. See issue #177.
* Fix a bug with joining a source and its source root when the source is above
the root. See issue #182.
* Add the `SourceMapConsumer.prototype.hasContentsOfAllSources` method to
determine when all sources' contents are inlined into the source map. See
issue #190.
## 0.4.2
* Add an `.npmignore` file so that the benchmarks aren't pulled down by
dependent projects. Issue #169.
* Add an optional `column` argument to
`SourceMapConsumer.prototype.allGeneratedPositionsFor` and better handle lines
with no mappings. Issues #172 and #173.
## 0.4.1
* Fix accidentally defining a global variable. #170.
## 0.4.0
* The default direction for fuzzy searching was changed back to its original
direction. See #164.
* There is now a `bias` option you can supply to `SourceMapConsumer` to control
the fuzzy searching direction. See #167.
* About an 8% speed up in parsing source maps. See #159.
* Added a benchmark for parsing and generating source maps.
## 0.3.0
* Change the default direction that searching for positions fuzzes when there is
not an exact match. See #154.
* Support for environments using json2.js for JSON serialization. See #156.
## 0.2.0
* Support for consuming "indexed" source maps which do not have any remote
sections. See pull request #127. This introduces a minor backwards
incompatibility if you are monkey patching `SourceMapConsumer.prototype`
methods.
## 0.1.43
* Performance improvements for `SourceMapGenerator` and `SourceNode`. See issue
#148 for some discussion and issues #150, #151, and #152 for implementations.
## 0.1.42
* Fix an issue where `SourceNode`s from different versions of the source-map
library couldn't be used in conjunction with each other. See issue #142.
## 0.1.41
* Fix a bug with getting the source content of relative sources with a "./"
prefix. See issue #145 and [Bug 1090768](bugzil.la/1090768).
* Add the `SourceMapConsumer.prototype.computeColumnSpans` method to compute the
column span of each mapping.
* Add the `SourceMapConsumer.prototype.allGeneratedPositionsFor` method to find
all generated positions associated with a given original source and line.
## 0.1.40
* Performance improvements for parsing source maps in SourceMapConsumer.
## 0.1.39
* Fix a bug where setting a source's contents to null before any source content
had been set before threw a TypeError. See issue #131.
## 0.1.38
* Fix a bug where finding relative paths from an empty path were creating
absolute paths. See issue #129.
## 0.1.37
* Fix a bug where if the source root was an empty string, relative source paths
would turn into absolute source paths. Issue #124.
## 0.1.36
* Allow the `names` mapping property to be an empty string. Issue #121.
## 0.1.35
* A third optional parameter was added to `SourceNode.fromStringWithSourceMap`
to specify a path that relative sources in the second parameter should be
relative to. Issue #105.
* If no file property is given to a `SourceMapGenerator`, then the resulting
source map will no longer have a `null` file property. The property will
simply not exist. Issue #104.
* Fixed a bug where consecutive newlines were ignored in `SourceNode`s.
Issue #116.
## 0.1.34
* Make `SourceNode` work with windows style ("\r\n") newlines. Issue #103.
* Fix bug involving source contents and the
`SourceMapGenerator.prototype.applySourceMap`. Issue #100.
## 0.1.33
* Fix some edge cases surrounding path joining and URL resolution.
* Add a third parameter for relative path to
`SourceMapGenerator.prototype.applySourceMap`.
* Fix issues with mappings and EOLs.
## 0.1.32
* Fixed a bug where SourceMapConsumer couldn't handle negative relative columns
(issue 92).
* Fixed test runner to actually report number of failed tests as its process
exit code.
* Fixed a typo when reporting bad mappings (issue 87).
## 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 issue 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

## Examples
### Consuming a source map
```js
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)
```js
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)
```js
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"

### 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 referenced 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`: Optional. The generated filename this source map is associated with.
```js
var consumer = new sourceMap.SourceMapConsumer(rawSourceMapJsonData);
```
#### SourceMapConsumer.prototype.computeColumnSpans()
Compute the last column for each generated mapping. The last column is
inclusive.
```js
// Before:
consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
// [ { line: 2,
// column: 1 },
// { line: 2,
// column: 10 },
// { line: 2,
// column: 20 } ]
consumer.computeColumnSpans();
// After:
consumer.allGeneratedPositionsFor({ line: 2, source: "foo.coffee" })
// [ { line: 2,
// column: 1,
// lastColumn: 9 },
// { line: 2,
// column: 10,
// lastColumn: 19 },
// { line: 2,
// column: 20,
// lastColumn: Infinity } ]
```
#### 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. Line numbers in
this library are 1-based (note that the underlying source map
specification uses 0-based line numbers -- this library handles the
translation).
* `column`: The column number in the generated source. Column numbers
in this library are 0-based.
* `bias`: Either `SourceMapConsumer.GREATEST_LOWER_BOUND` or
`SourceMapConsumer.LEAST_UPPER_BOUND`. Specifies whether to return the closest
element that is smaller than or greater than the one we are searching for,
respectively, if the exact element cannot be found. Defaults to
`SourceMapConsumer.GREATEST_LOWER_BOUND`.
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. The line number is 1-based.
* `column`: The column number in the original source, or null if this
information is not available. The column number is 0-based.
* `name`: The original identifier, or null if this information is not available.
```js
consumer.originalPositionFor({ line: 2, column: 10 })
// { source: 'foo.coffee',
// line: 2,
// column: 2,
// name: null }
consumer.originalPositionFor({ line: 99999999999999999, column: 999999999999999 })
// { source: null,
// line: null,
// column: null,
// name: null }
```
#### 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. The line number is
1-based.
* `column`: The column number in the original source. The column
number is 0-based.
and an object is returned with the following properties:
* `line`: The line number in the generated source, or null. The line
number is 1-based.
* `column`: The column number in the generated source, or null. The
column number is 0-based.
```js
consumer.generatedPositionFor({ source: "example.js", line: 2, column: 10 })
// { line: 1,
// column: 56 }
```
#### SourceMapConsumer.prototype.allGeneratedPositionsFor(originalPosition)
Returns all generated line and column information for the original source, line,
and column provided. If no column is provided, returns all mappings
corresponding to a either the line we are searching for or the next closest line
that has any mappings. Otherwise, returns all mappings corresponding to the
given line and either the column we are searching for or the next closest column
that has any offsets.
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. The line number is
1-based.
* `column`: Optional. The column number in the original source. The
column number is 0-based.
and an array of objects is returned, each with the following properties:
* `line`: The line number in the generated source, or null. The line
number is 1-based.
* `column`: The column number in the generated source, or null. The
column number is 0-based.
```js
consumer.allGeneratedpositionsfor({ line: 2, source: "foo.coffee" })
// [ { line: 2,
// column: 1 },
// { line: 2,
// column: 10 },
// { line: 2,
// column: 20 } ]
```
#### SourceMapConsumer.prototype.hasContentsOfAllSources()
Return true if we have the embedded source content for every source listed in
the source map, false otherwise.
In other words, if this method returns `true`, then
`consumer.sourceContentFor(s)` will succeed for every source `s` in
`consumer.sources`.
```js
// ...
if (consumer.hasContentsOfAllSources()) {
consumerReadyCallback(consumer);
} else {
fetchSources(consumer, consumerReadyCallback);
}
// ...
```
#### SourceMapConsumer.prototype.sourceContentFor(source[, returnNullOnMissing])
Returns the original source content for the source provided. The only
argument is the URL of the original source file.
If the source content for the given source is not found, then an error is
thrown. Optionally, pass `true` as the second param to have `null` returned
instead.
```js
consumer.sources
// [ "my-cool-lib.clj" ]
consumer.sourceContentFor("my-cool-lib.clj")
// "..."
consumer.sourceContentFor("this is not in the source map");
// Error: "this is not in the source map" is not in the source map
consumer.sourceContentFor("this is not in the source map", true);
// null
```
#### 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`.
```js
consumer.eachMapping(function (m) { console.log(m); })
// ...
// { source: 'illmatic.js',
// generatedLine: 1,
// generatedColumn: 0,
// originalLine: 1,
// originalColumn: 0,
// name: null }
// { source: 'illmatic.js',
// generatedLine: 2,
// generatedColumn: 0,
// originalLine: 2,
// originalColumn: 0,
// name: null }
// ...
```
### SourceMapGenerator
An instance of the SourceMapGenerator represents a source map which is being
built incrementally.
#### new SourceMapGenerator([startOfSourceMap])
You may pass an object with the following properties:
* `file`: The filename of the generated source that this source map is
associated with.
* `sourceRoot`: A root for all relative URLs in this source map.
* `skipValidation`: Optional. When `true`, disables validation of mappings as
they are added. This can improve performance but should be used with
discretion, as a last resort. Even then, one should avoid using this flag when
running tests, if possible.
```js
var generator = new sourceMap.SourceMapGenerator({
file: "my-generated-javascript-file.js",
sourceRoot: "http://example.com/app/js/"
});
```
#### SourceMapGenerator.fromSourceMap(sourceMapConsumer)
Creates a new `SourceMapGenerator` from an existing `SourceMapConsumer` instance.
* `sourceMapConsumer` The SourceMap.
```js
var generator = sourceMap.SourceMapGenerator.fromSourceMap(consumer);
```
#### 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.
```js
generator.addMapping({
source: "module-one.scm",
original: { line: 128, column: 0 },
generated: { line: 3, column: 456 }
})
```
#### 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.
```js
generator.setSourceContent("module-one.scm",
fs.readFileSync("path/to/module-one.scm"))
```
#### SourceMapGenerator.prototype.applySourceMap(sourceMapConsumer[, sourceFile[, sourceMapPath]])
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 minimum 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, if it exists.
Otherwise an error will be thrown.
* `sourceMapPath`: Optional. The dirname of the path to the SourceMap
to be applied. If relative, it is relative to the SourceMap.
This parameter is needed when the two SourceMaps aren't in the same
directory, and the SourceMap to be applied contains relative source
paths. If so, those relative source paths need to be rewritten
relative to the SourceMap.
If omitted, it is assumed that both SourceMaps are in the same directory,
thus not needing any rewriting. (Supplying `'.'` has the same effect.)
#### SourceMapGenerator.prototype.toString()
Renders the source map being generated to a string.
```js
generator.toString()
// '{"version":3,"sources":["module-one.scm"],"names":[],"mappings":"...snip...","file":"my-generated-javascript-file.js","sourceRoot":"http://example.com/app/js/"}'
```
### 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. The line number is 1-based.
* `column`: The original column number associated with this source node, or null
if it isn't associated with an original column. The column number
is 0-based.
* `source`: The original source's filename; null if no filename is provided.
* `chunk`: Optional. Is immediately passed to `SourceNode.prototype.add`, see
below.
* `name`: Optional. The original identifier.
```js
var node = new SourceNode(1, 2, "a.cpp", [
new SourceNode(3, 4, "b.cpp", "extern int status;\n"),
new SourceNode(5, 6, "c.cpp", "std::string* make_string(size_t n);\n"),
new SourceNode(7, 8, "d.cpp", "int main(int argc, char** argv) {}\n"),
]);
```
#### SourceNode.fromStringWithSourceMap(code, sourceMapConsumer[, relativePath])
Creates a SourceNode from generated code and a SourceMapConsumer.
* `code`: The generated code
* `sourceMapConsumer` The SourceMap for the generated code
* `relativePath` The optional path that relative sources in `sourceMapConsumer`
should be relative to.
```js
var consumer = new SourceMapConsumer(fs.readFileSync("path/to/my-file.js.map", "utf8"));
var node = SourceNode.fromStringWithSourceMap(fs.readFileSync("path/to/my-file.js"),
consumer);
```
#### 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.
```js
node.add(" + ");
node.add(otherNode);
node.add([leftHandOperandNode, " + ", rightHandOperandNode]);
```
#### 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.
```js
node.prepend("/** Build Id: f783haef86324gf **/\n\n");
```
#### 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
```js
node.setSourceContent("module-one.scm",
fs.readFileSync("path/to/module-one.scm"))
```
#### 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.
```js
var node = new SourceNode(1, 2, "a.js", [
new SourceNode(3, 4, "b.js", "uno"),
"dos",
[
"tres",
new SourceNode(5, 6, "c.js", "quatro")
]
]);
node.walk(function (code, loc) { console.log("WALK:", code, loc); })
// WALK: uno { source: 'b.js', line: 3, column: 4, name: null }
// WALK: dos { source: 'a.js', line: 1, column: 2, name: null }
// WALK: tres { source: 'a.js', line: 1, column: 2, name: null }
// WALK: quatro { source: 'c.js', line: 5, column: 6, name: null }
```
#### 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.
```js
var a = new SourceNode(1, 2, "a.js", "generated from a");
a.setSourceContent("a.js", "original a");
var b = new SourceNode(1, 2, "b.js", "generated from b");
b.setSourceContent("b.js", "original b");
var c = new SourceNode(1, 2, "c.js", "generated from c");
c.setSourceContent("c.js", "original c");
var node = new SourceNode(null, null, null, [a, b, c]);
node.walkSourceContents(function (source, contents) { console.log("WALK:", source, ":", contents); })
// WALK: a.js : original a
// WALK: b.js : original b
// WALK: c.js : original c
```
#### 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.
```js
var lhs = new SourceNode(1, 2, "a.rs", "my_copy");
var operand = new SourceNode(3, 4, "a.rs", "=");
var rhs = new SourceNode(5, 6, "a.rs", "orig.clone()");
var node = new SourceNode(null, null, null, [ lhs, operand, rhs ]);
var joinedNode = node.join(" ");
```
#### SourceNode.prototype.replaceRight(pattern, replacement)
Call `String.prototype.replace` on the very right-most source snippet. Useful
for trimming white space from the end of a source node, etc.
* `pattern`: The pattern to replace.
* `replacement`: The thing to replace the pattern with.
```js
// Trim trailing white space.
node.replaceRight(/\s*$/, "");
```
#### 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.
```js
var node = new SourceNode(1, 2, "a.js", [
new SourceNode(3, 4, "b.js", "uno"),
"dos",
[
"tres",
new SourceNode(5, 6, "c.js", "quatro")
]
]);
node.toString()
// 'unodostresquatro'
```
#### 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`.
```js
var node = new SourceNode(1, 2, "a.js", [
new SourceNode(3, 4, "b.js", "uno"),
"dos",
[
"tres",
new SourceNode(5, 6, "c.js", "quatro")
]
]);
node.toStringWithSourceMap({ file: "my-output-file.js" })
// { code: 'unodostresquatro',
// map: [object SourceMapGenerator] }
```
