What does this do?

This will get you the bleeding-edge syntax highlighting for C++. This used to be a fix, but then VS Code starting using it as the official source for C++ highlighting.

How do I use it?

Just install the VS Code extension and the changes will automatically be applied to all C++/C files.

What is different from atom/language-c?

It fixes:

  • The issue of single quotes inside #error and #warning being highlighted when then shouldn't be
  • The issue of initilization functions only highlighting the first paraenthese
  • The bug that treats the 'and' and 'or' operator as functions (instead of operators) when they are followed by ()'s
  • Old C99 function highlighting that broke the standard function highlighting
  • The failure of highlighting for the semicolon after namespaces
  • The missing operator overloading symbols
  • The failure to tag operator overloading functions as functions
  • The failure to tag implicit operator overrides
  • The marking of some %'s as invalid inside of strings https://github.com/atom/language-c/issues/289
  • The highlighting of namespaces with ::'s https://github.com/atom/language-c/issues/260
  • The issue of the C++ syntax depending on (and getting screwed up by) the C syntax
  • And many many more issues (#318, #309, #270, #246, etc)

It adds:

  • Parameter highlighting
  • Lambda highlighting
  • C++14 literal support (100'000ms)
  • Template definition syntax highlighting (including C++ 2020 syntax)
  • Better object identification
  • Improved scope resolution :: syntax
  • Highlighting of templated function calls aFunction<int>(arguments)
  • Additional specificity for many existing tags
  • Many other features

Contributing

This is a project that is converting legacy JSON file into ruby files that generate a JSON file. The main ruby file "generate.rb" uses tools (that are in beta) that help generate the JSON file. If you want to contribute, take a look at number_literal = newPattern( inside of "generate.rb" to see how the new syntax looks. Take a look at "comments-c" => { to see how the old syntax looks. The code is ready for contributions, and in the future there will be much more documentation for contributors.

Planned future fixes/featues:

  • Fix multiple inheritance https://github.com/atom/language-c/issues/245
  • Start coding patterns according to the offical C++ syntax specifications
  • Fix function-pointer tagging
  • Add tagging for type-casting statements
  • Add tagging for template-usage (rather than only template definition)
  • Add tagging for custom types words
  • Better support for dereferenced/pointer tagging

What if I see a highlighting bug?

Let me know! Post an issue on https://github.com/jeff-hykin/cpp-textmate-grammar I love regular expressions, and I plan on actively maintaining this.

Did you write all of this youself?

The original JSON was taken from https://github.com/atom/language-c
The #error fix was taken from fnadeau's pull request here: https://github.com/atom/language-c/pull/251
@matter123 has written almost every pull request, containing entirely new patterns and fixes for numerous things
Thanks fnadeau and @matter123!
