# Change Log ## 0.8.0-beta.0 ### Breaking changes - [#350](https://github.com/mozilla/source-map/pull/350) - Change browser detection logic for WASM loading. - [#363](https://github.com/mozilla/source-map/pull/363) - Change WASM loading detection to rely on `package.json#browser` field. - [#362](https://github.com/mozilla/source-map/pull/362) - Remove the `dist/` bundle. - [#371](https://github.com/mozilla/source-map/pull/371) - Reimplement sourcemap URL processing using the WHATWG URL API. ### Nonbreaking changes: - [#339](https://github.com/mozilla/source-map/pull/339) - Allow initializing the consumer `mappings.wasm` file as an `ArrayBuffer`. ### Internal Improvements: - [#347](https://github.com/mozilla/source-map/pull/347) - Improve tests. - [#352](https://github.com/mozilla/source-map/pull/352) - Improve documentation. - [#361](https://github.com/mozilla/source-map/pull/361) - Use newer Webpack CLI when bundling. - [#364](https://github.com/mozilla/source-map/pull/364) - Convert `IndexedSourceMapConsumer` implementation to pass more through to `BasicSourceMapConsumer`. - [#366](https://github.com/mozilla/source-map/pull/366) - Normalize internal URL representation to be easier to follow. - [#341](https://github.com/mozilla/source-map/pull/341) - Use async functions to simplify `SourceMapConsumer.with` implementation. ## 0.7.3 - Fix a bug where nested uses of `SourceMapConsumer` could result in a `TypeError`. [#338](https://github.com/mozilla/source-map/issues/338) [#330](https://github.com/mozilla/source-map/issues/330) [#319](https://github.com/mozilla/source-map/issues/319) ## 0.7.2 - Another 3x speed up in `SourceMapConsumer`. Read about it here: http://fitzgeraldnick.com/2018/02/26/speed-without-wizardry.html ## 0.7.1 - Updated TypeScript typings. [#321][] [#321]: https://github.com/mozilla/source-map/pull/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 `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 - Added name support to SourceNode. ## 0.1.10 - Added sourcesContent support to the customer and generator.
