Change Log

0.7.3

  • Fix a bug where nested uses of SourceMapConsumer could result in a TypeError. #338 #330 #319

0.7.2

0.7.1

  • Updated TypeScript typings. #321

0.7.0

  • SourceMapConsumer now uses WebAssembly, and is much faster! Read about it here: https://hacks.mozilla.org/2018/01/oxidizing-source-maps-with-rust-and-webassembly/

  • Breaking change: new SourceMapConsumer now returns a Promise object that resolves to the newly constructed SourceMapConsumer instance, rather than returning the new instance immediately.

  • Breaking change: when you're done using a SourceMapConsumer instance, you must call SourceMapConsumer.prototype.destroy on it. After calling destroy, you must not use the instance again.

  • Breaking change: SourceMapConsumer used to be able to handle lines, columns numbers and source and name indices up to 2^53 - 1 (aka Number.MAX_SAFE_INTEGER). It can now only handle them up to 2^32 - 1.

  • Breaking change: The source-map library now uses modern ECMAScript-isms: let, arrow functions, async, etc. Use Babel to compile it down to ECMAScript 5 if you need to support older JavaScript environments.

  • Breaking change: Drop support for Node < 8. If you want to support older versions of node, please use v0.6 or below.

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 SourceNodes 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.

  • 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 SourceNodes. 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

0.1.24

0.1.23
