Additional Declaration Highlights

[kbenzie]

After using vim-cpp-enhanced-highlight for a while I've grown used to function and (some) namespace highlighting. I've become frustrated at the inconsistency of highlighting this plugin show due to only STL namespaces being highlighted and also by the highlighting of certain STL keywords.

I like how clighter highlights enums and macros but still find the results bland for other general code. My requests, in order of preference, are as follows.

1. Function invocations
2. Function declarations
3. Namespace qualifiers
4. Member qualifiers

I can provide examples of the desired results if you feel this would be something you would like to add in future. Thanks for the interesting plugin.

I have added 4 highlight groups into clighter, but all of them are link to "None" by default, because it's a little annoying.

The added highlight groups work great. Is it possible to also add a highlight group for function invocations/calls? With function calls (and template classes) highlighted, this plugin would replace vim-cpp-enhanced-highlight for me.

This recently got posted on LLVM weekly, color_coded

[bbchung]

I will list all highlight groups in next release, and make them as an option

[bbchung]

plz update clighter to get these work, and this is default settings.

1.Function invocations
hi default link clighterDeclRefExprCall Identifier -> disable

2.Function declarations
hi default link clighterFunctionDecl Function -> disable

3.Namespace qualifiers
hi default link clighterNamespace Type -> disable

4.Member qualifiers
hi default link clighterFieldDecl Type -> disable
hi default link clighterMemberRefExpr Identifier -> disable

1. template class
   behavior should like normal class in the newest version

1~4 is disabled by default, because
let g:clighter_syntax_groups = get(g:, 'clighter_syntax_groups', ['clighterMacroInstantiation', 'clighterStructDecl', 'clighterClassDecl', 'clighterEnumDecl', 'clighterEnumConstantDecl', 'clighterTypeRef', 'clighterDeclRefExprEnum'])

you can enable them by set g:clighter_syntax_groups, for example
let g:clighter_syntax_groups = get(g:, 'clighter_syntax_groups', ['clighterMacroInstantiation', 'clighterStructDecl', 'clighterClassDecl', 'clighterEnumDecl', 'clighterEnumConstantDecl', 'clighterTypeRef', 'clighterDeclRefExprEnum','clighterDeclRefExprCall','clighterFunctionDecl','clighterNamespace','clighterFieldDecl','clighterMemberRefExpr'])

Clang provides too many type to highlight, enable all type is not unrealistic and low performance, so if there is any type should be highlighted in the future, just tell me.

With the latest version function invocations now work, and class template declarations as well. Great work!

Three things that are not yet included in any syntax group:

• Templated variable types

• Template arguments in function declarations: in the following example It is not hightlighted after class, or before from/to, but it is highlighted inside pair.

  template<class It>
  vector<pair<It, It>> divide(It from, It to, const std::ptrdiff_t number)
  

• Function declarations inside classes in the headers.

Ok, I add more template support in 95e48b5 . By the way, in my environment, 'It' before 'from'/'to' is highlighted in 2b36f5e.

Thanks for your testing and keep testing :)

Fixed:

• I got 'It' in the above example highlighted correctly in the latest commit.
• Templated variably types work too.

Left to do:

• Functions declarations inside classes, such as

  class Test {
      void func();
  };
  

• In the following example, std::vector in the return statement is not highlighted:

  std::vector<int> func1(int x) {
      return std::vector<int>(x);
  }

Great work adding class functions in 2ac874a.
Constructors are not yet highlighted though...

[octol]

Another missing highlight:

std::for_each(begin(threads), end(threads), [](std::thread & t) { t.join(); });

Here "join" is not highlighted as a function.

[octol]

Also:

vector<int> test = {1, 2};
vector<int> test2(test.size());

"size" is not highlighted as a function
