在VIM中更改`rubyLocalVariableOrMethod`颜色

Question

I was wondering whether it's possible to change the rubyLocalVariableOrMethod color in a mytheme.vim color scheme file.

I am currently extending the ir_black theme which I really like, and want to overwrite just a few a colors for certain keywords.

This is my current color scheme that extends from ir_black .

runtime colors/ir_black.vim

let g:colors_name = "mytheme"

hi rubyDefine ctermfg=darkblue
hi rubyFunction ctermfg=lightblue
hi rubyConstant ctermfg=lightblue
hi rubyString ctermfg=green
hi rubyInteger ctermfg=red
hi rubyFloat ctermfg=red
hi rubyLocalVariableOrMethod ctermfg=white

Everything works as expected except for hi rubyLocalVariableOrMethod ctermfg=white . The color remains something that looks like gray . I thought perhaps ir_black was setting a certain value that my rubyLocalVariableOrMethod could not overwrite, but I failed to find anything.

Perhaps someone more experienced in VIM could help me out with this.

This is the link to the ir_black I'm using:
https://github.com/wgibbs/vim-irblack/blob/master/colors/ir_black.vim

This is the ruby syntax file I am using:
https://github.com/vim-ruby/vim-ruby/blob/master/syntax/ruby.vim

Any help figuring out why I'm failing to overwrite the gray -looking color would be much appreciated!

Answer 1

Mine was actually "display transparent" in the syntax highlighting plugin.

~/.vim/bundle/vim-ruby/syntax/ruby.vim
92:syn match rubyLocalVariableOrMethod "\<[_[:lower:]][_[:alnum:]]*[?!=]\=" contains=NONE display transparent

I removed it and magic!

Turns out my Terminal ( iTerm2 )'s Foreground property wasn't set to "full white". Didn't expect that to have any influence, but good to know in case anyone else runs in to this gotcha.
