hash syntax highlighting

[Ritchie Lee]

Hello,

I'm looking for hash syntax highlighting capability --- words that are not highlighted as keywords, such as user variables, etc., are hashed to a random color. The color would be consistent for the same variable though. This makes it easy to spot where the variable is being used at a glance.

If this sort of plugin is not already available, how would I go about implementing it? Or adding it to an existing syntax plugin?

Thanks!

HI Ritchie,

Maybe this is something you'll find useful.

I use an older plugin highlights.vim [1] and have added the following to my .vimrc

--- snip ---

" The leader defaults to backslash, so (by default) this maps \* and \g* (see :help Leader).

" These work like * and g*, but do not move the cursor and always set hls.

map         <Leader>*       :let @/ = '\<'.expand('<cword>').'\>'\|set hlsearch<C-M>

map         <Leader>g*      :let @/ = expand('<cword>')\|set hlsearch<C-M>

nm          <Leader>1       :Highlight 1 <C-R>='\<'.expand("<cword>").'\>'<CR><CR>

nm          <Leader>2       :Highlight 2 <C-R>='\<'.expand("<cword>").'\>'<CR><CR>

nm          <Leader>3       :Highlight 3 <C-R>='\<'.expand("<cword>").'\>'<CR><CR>

nm          <Leader>4       :Highlight 4 <C-R>='\<'.expand("<cword>").'\>'<CR><CR>

nm          <Leader>5       :Highlight 5 <C-R>='\<'.expand("<cword>").'\>'<CR><CR>

nm          <Leader>0       :Hclear <C-R>='\<'.expand("<cword>").'\>'<CR><CR>

nm          <Leader>*0      :Hclear *<CR><CR>

--- end snip ---

And this gives me a quick and efficient way to uniquely highlight the keyword under the cursor with one of <Leader>1-9. Turn off highlighting the specific keyword under cursor with <Leader>0; to disable all highlights I execute ":hclear".

You'll additionally need to provide your own hightlights.csv in the same directory as highlights.vim. Here is mine as an example

--- snip ---

hlnum,ctermfg,ctermbg,guifg,guibg

1,white,red,white,red

2,white,blue,white,blue

3,white,green,white,green

4,white,magenta,white,magenta

5,white,black,white,black

6,white,red,white,red

7,white,blue,white,blue

8,white,green,white,green

9,white,magenta,white,magenta

--- end snip ---
