# combine-source-map [![build status](https://secure.travis-ci.org/thlorenz/combine-source-map.png)](http://travis-ci.org/thlorenz/combine-source-map)
Add source maps of multiple files, offset them and then combine them into one source map.
```js
var convert = require('convert-source-map');
var combine = require('combine-source-map');
var fooComment = '//# sourceMappingURL=data:application/json;base64,eyJ2Z [..] pzJylcbiJdfQ==';
var barComment = '//# sourceMappingURL=data:application/json;base64,eyJ2Z [..] VjaycpXG4iXX0=';
var fooFile = {
source: '(function() {\n\n console.log(require(\'./bar.js\'));\n\n}).call(this);\n' + '\n' + fooComment
, sourceFile: 'foo.js'
};
var barFile = {
source: '(function() {\n\n console.log(alert(\'alerts suck\'));\n\n}).call(this);\n' + '\n' + barComment
, sourceFile: 'bar.js'
};
var offset = { line: 2 };
var base64 = combine
.create('bundle.js')
.addFile(fooFile, offset)
.addFile(barFile, { line: offset.line + 8 })
.base64();
var sm = convert.fromBase64(base64).toObject();
console.log(sm);
```
```
{ version: 3,
file: 'bundle.js',
sources: [ 'foo.coffee', 'bar.coffee' ],
names: [],
mappings: ';;;AAAA;CAAA;CAAA,CAAA,CAAA,IAAO,GAAK;CAAZ;;;;;ACAA;CAAA;CAAA,CAAA,CAAA,IAAO,GAAK;CAAZ',
sourcesContent:
[ 'console.log(require \'./bar.js\')\n',
'console.log(alert \'alerts suck\')\n' ] }
```
## Installation
npm install combine-source-map
## API
### create()
```
/**
* @name create
* @function
* @param file {String} optional name of the generated file
* @param sourceRoot { String} optional sourceRoot of the map to be generated
* @return {Object} Combiner instance to which source maps can be added and later combined
*/
```
### Combiner.prototype.addFile(opts, offset)
```
/**
* Adds map to underlying source map.
* If source contains a source map comment that has the source of the original file inlined it will offset these
* mappings and include them.
* If no source map comment is found or it has no source inlined, mappings for the file will be generated and included
*
* @name addMap
* @function
* @param opts {Object} { sourceFile: {String}, source: {String} }
* @param offset {Object} { line: {Number}, column: {Number} }
*/
```
### Combiner.prototype.base64()
```
/**
* @name base64
* @function
* @return {String} base64 encoded combined source map
*/
```
### Combiner.prototype.comment()
```
/**
* @name comment
* @function
* @return {String} base64 encoded sourceMappingUrl comment of the combined source map
*/
```
### removeComments(src)
```
/**
* @name removeComments
* @function
* @param src
* @return {String} src with all sourceMappingUrl comments removed
*/
```
## Example
Read and run the [more elaborate example](https://github.com/thlorenz/combine-source-map/blob/master/example/two-files.js)

[![NPM](https://nodei.co/npm/convert-source-map.png?downloads=true&stars=true)](https://nodei.co/npm/convert-source-map/)
Converts a source-map from/to different formats and allows adding/changing properties.
```js
var convert = require('convert-source-map');
var json = convert
.fromComment('//# sourceMappingURL=data:application/json;base64,eyJ2ZXJzaW9uIjozLCJmaWxlIjoiZm9vLmpzIiwic291cmNlcyI6WyJjb25zb2xlLmxvZyhcImhpXCIpOyJdLCJuYW1lcyI6W10sIm1hcHBpbmdzIjoiQUFBQSIsInNvdXJjZVJvb3QiOiIvIn0=')

.setProperty('sources', [ 'CONSOLE.LOG("HI");' ])
.toJSON();
console.log(json);
console.log(modified);
```
```json
{"version":3,"file":"foo.js","sources":["console.log(\"hi\");"],"names":[],"mappings":"AAAA","sourceRoot":"/"}
{"version":3,"file":"foo.js","sources":["CONSOLE.LOG(\"HI\");"],"names":[],"mappings":"AAAA","sourceRoot":"/"}
```
## API
### fromObject(obj)
Returns source map converter from given object.
### fromJSON(json)
Returns source map converter from given json string.
### fromBase64(base64)
Returns source map converter from given base64 encoded json string.
### fromComment(comment)
Returns source map converter from given base64 encoded json string prefixed with `//# sourceMappingURL=...`.
### fromMapFileComment(comment, mapFileDir)
Returns source map converter from given `filename` by parsing `//# sourceMappingURL=filename`.
`filename` must point to a file that is found inside the `mapFileDir`. Most tools store this file right next to the
generated file, i.e. the one containing the source map.
### fromSource(source[, largeSource])
Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was found.
If `largeSource` is set to `true`, an algorithm that does not use regex is applied to find the source map. This is faster and especially useful if you're running into "call stack size exceeded" errors with the default algorithm.
However, it is less accurate and may match content that isn't a source map comment.
### fromMapFileSource(source, mapFileDir)
Finds last sourcemap comment in file and returns source map converter or returns null if no source map comment was
found.
The sourcemap will be read from the map file found by parsing `# sourceMappingURL=file` comment. For more info see
fromMapFileComment.
### toObject()
Returns a copy of the underlying source map.
### toJSON([space])
Converts source map to json string. If `space` is given (optional), this will be passed to
[JSON.stringify](https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/JSON/stringify) when the
JSON string is generated.
### toBase64()
Converts source map to base64 encoded json string.
### toComment([options])
Converts source map to an inline comment that can be appended to the source-file.
By default, the comment is formatted like: `//# sourceMappingURL=...`, which you would
normally see in a JS source file.
When `options.multiline == true`, the comment is formatted like: `/*# sourceMappingURL=... */`, which you would find in a CSS source file.
### addProperty(key, value)
Adds given property to the source map. Throws an error if property already exists.
### setProperty(key, value)
Sets given property to the source map. If property doesn't exist it is added, otherwise its value is updated.
### getProperty(key)
Gets given property of the source map.
### removeComments(src)
Returns `src` with all source map comments removed
### removeMapFileComments(src)
Returns `src` with all source map comments pointing to map files removed.
### commentRegex
Returns the regex used to find source map comments.
### mapFileCommentRegex
Returns the regex used to find source map comments pointing to map files.

# 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
* 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.
## 0.1.22
* Ignore duplicate mappings in SourceMapGenerator. Fixes github issue 21.
## 0.1.21
* Fixed handling of sources that start with a slash so that they are relative to
the source root's host.
## 0.1.20
* Fixed github issue #43: absolute URLs aren't joined with the source root
anymore.
## 0.1.19
* Using Travis CI to run tests.
## 0.1.18
* Fixed a bug in the handling of sourceRoot.
## 0.1.17
* Added SourceNode.fromStringWithSourceMap.
## 0.1.16
* Added missing documentation.
* Fixed the generating of empty mappings in SourceNode.
## 0.1.15
* Added SourceMapGenerator.applySourceMap.
## 0.1.14
* The sourceRoot is now handled consistently.
## 0.1.13
* Added SourceMapGenerator.fromSourceMap.
## 0.1.12
* SourceNode now generates empty mappings too.
## 0.1.11

## 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"
});
console.log(map.toString());
// '{"version":3,"file":"source-mapped.js","sources":["foo.js"],"names":["christopher"],"mappings":";;;;;;;;;mCAgCEA"}'
```
## API
Get a reference to the module:
```js
// Node.js
var sourceMap = require('source-map');
// Browser builds
var sourceMap = window.sourceMap;
// Inside Firefox
const sourceMap = require("devtools/toolkit/sourcemap/source-map.js");
```
### 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.
* `column`: The column number in the generated source.
* `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.
* `column`: The column number in the original source, or null if this
information is not available.
* `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.
* `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.
```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.
* `column`: Optional. The column number in the original source.
and an array of objects is returned, each with the following properties:
* `line`: The line number in the generated source, or null.
* `column`: The column number in the generated source, or null.
```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.
* `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; 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] }
```
