CHANGELOG.md
# Change Log
## 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

/**
* 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.
*
* The only parameter is the raw source map (either as a JSON string, or
* already parsed to 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: Optional. The generated file this source map is associated with.
*
* Here is an example source map, taken from the source map spec[0]:
*
* {
* version : 3,
* file: "out.js",
* sourceRoot : "",
* sources: ["foo.js", "bar.js"],
* names: ["src", "maps", "are", "fun"],
