Changelog

Sourced from syntect's changelog.

Version 4.1.0 (2020-03-30)

• Make sure errors implement Send #285
• Fix errors to not use the deprecated description() #286

Thanks @sharkdp for the bug fixes! Bumping second part of semver since Send is adding functionality (back).

Version 4.0.0 (2020-03-29)

Headline feature: pure-Rust fancy-regex engine option

Users can now opt in to a pure-Rust regex engine using Cargo features, making compilation easier in general. People experiencing difficulty compiling for Windows and Wasm should try switching to fancy-regex. Note this currently approximately halves highlighting speed.

See the Readme and #270 for details. Thanks to @robinst for implementing this!

Other changes

• Ability to generate CSS for a theme for use with classed HTML generation (won't always be correct) #274
• Don't generate empty spans in classed HTML #276
• Miscellaneous dependency bumps and cleanup

Breaking changes and upgrading

Upgrading should cause no errors for nearly all users. Users using more unusual APIs may have a small amount of tweaking to do.

• If you use default-features = false you may need to update your features to choose a regex engine
• A bunch of technically public APIs that I don't know if anyone uses changed due to the regex engine refactor, common uses shouldn't break

Version 3.3.0 (2019-09-22)

Bug fixes and new utilities

• Fixes multiple bugs
• Add RangedHighlightIterator
• Add as_latex_escaped util

Version 3.2.1 (2019-08-10)

Fan of this - this makes onig optional and allows people to use a pure rust alternative.

[mre]

That's nice! I wonder why the CI didn't run... 🤔

[mre]

Maybe because I don't have a CI yet. 😅 Will add that now.

[mre]

See #25

@dependabot rebase

[mre]

Just released prettyprint 0.8 with this PR merged in. 🎉 @gilescope fyi

[sharkdp]

Note that you might need something like what we did in https://github.com/sharkdp/bat/pull/900 in order to allow users to choose between onig and fancy-regex.

Also, note that the binary syntax assets are not compatible with the fancy-regex version (as described in the linked PR as well).

[mre]

Thanks for the heads up @sharkdp. I don't think I'll add this myself due to focusing on other projects at the moment and trying to redirect future users to bat. That said, maybe you could add the flags @gilescope? PR would be very much appreciated.

[gilescope]

Sure I can do that :-)
