调整Vim colorscheme的ruby哈希语法键：：val

Question

Is there a way to have the value symbol or key symbol in a key-value pair highlighted differently?

something like:

ruby: :has_nice_hash

Answer 1

If you want to modify the colour of a specific syntax token in Vim you have to know its idName. You can place the cursor on the token and then on the command line type the following command:

:echo synIDattr(synID(line("."), col("."), 1), "name")

In the case of the ruby hash you'll get rubySymbol . Now with this information you can do something like:

:hi rubySymbol guifg=red

Of course you'll have to tweak the colors based on your needs. See docs for further information.
