|
|
* A BasicSourceMapConsumer 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 first 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"],
|
|
* mappings: "AA,AB;;ABCDE;"
|
|
* }
|
|
*
|
|
* The second parameter, if given, is a string whose value is the URL
|
|
* at which the source map was found. This URL is used to compute the
|
|
* sources array.

|
|
* that it takes "indexed" source maps (i.e. ones with a "sections" field) as
|
|
* input.
|
|
*
|
|
* The first parameter is a raw source map (either as a JSON string, or already
|
|
* parsed to an object). According to the spec for indexed source maps, they
|
|
* have the following attributes:
|
|
*
|
|
* - version: Which version of the source map spec this map is following.
|
|
* - file: Optional. The generated file this source map is associated with.
|
|
* - sections: A list of section definitions.
|
|
*
|
|
* Each value under the "sections" field has two fields:
|
|
* - offset: The offset into the original specified at which this section
|
|
* begins to apply, defined as an object with a "line" and "column"
|
|
* field.
|
|
* - map: A source map definition. This source map could also be indexed,
|
|
* but doesn't have to be.
|
|
*
|
|
* Instead of the "map" field, it's also possible to have a "url" field
|
|
* specifying a URL to retrieve a source map from, but that's currently
|
|
* unsupported.
|
|
*
|
|
* Here's an example source map, taken from the source map spec[0], but
|
|
* modified to omit a section which uses the "url" field.
|
|
*
|
|
* {
|
|
* version : 3,
|
|
* file: "app.js",
|
|
* sections: [{
|
|
* offset: {line:100, column:10},
|
|
* map: {
|
|
* version : 3,
|
|
* file: "section.js",
|
|
* sources: ["foo.js", "bar.js"],
|
|
* names: ["src", "maps", "are", "fun"],
|
|
* mappings: "AAAA,E;;ABCDE;"
|
|
* }
|
|
* }],
|
|
* }
|
|
*
|
|
* The second parameter, if given, is a string whose value is the URL
|
|
* at which the source map was found. This URL is used to compute the
|
|
* sources array.
