Version 10 Breaking Changes

[joshgoebel]

Creating an issue to keep track of all the "breaking changes" I'd like to do when we get around to major release time.

• Expose parse tree, renderer, and new emitter API. enh(parser) Refactor parse tree and HTML render into components #2404
• Rename cs.js to csharp.js
• Rename tex.js to latex.js
• No prohibition against using ES2015 features in the codebase (will cut out a few older browsers we currently technically might support)
• Review ":common" group for potential removals
• remove older onload hook, keeping newer DOMContentLoaded.
• remove darkula.css (mispelling)
• remove restoreLanguageAPI (version 9 compressed languages are not compatible with version 10)
• Good time to split C/C++ with a common foundation if we have anyone to work on that Create C/C++ dependency on 'c-like' to prevent future breaking changes (cpp) syntax should be split into C and C++ syntaxes #2146
• consider XML/PHP entanglement and how to resolve Discuss: How we handle the PHP templating language #2330
• [in progress] Fix-up htmlbars and handlebars dependencies (htmlbars) should inherit from Handlebars #2181
• 3rd party language grammar official packaging format Discuss: 3rd party language packages spec #2328
• New build system Build system for 2019 #1759
• Resolve build inconsistency issues: highlightjs.org build seems to differ from ./tools/build.js -t browser :common #2291
• Switch to createElement vs NS

Thing that probably aren't making it into 10.0

• Consider deprecating endSameAsBegin and encourage callback use instead (cpp) Fix highlighting of unterminated raw strings #2261
• auto highlighting should return a list of possible matches, not just top two
• Change highlight(name, x, x, x) API to highlight(code, options={}), we'd still support the legacy API until 11.0 I'd imagine. Propose: Improve highlight API #2277
• add baseLanguage to some language grammars and Add baseLangage to language grammars #2275

Closing out, so close. Remaining issues will stand on their own (and may not make it into v10).
