# Change Log
|
||||
|
||||
## 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
|
||||

||||
|
||||
## 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
|
||||
|
||||
