Question

I’m trying to define a user function in vim to change the current color scheme, then override some of the theme’s settings to make it work better with my transparent terminal configuration. I can’t seem to find any info on how to call set lines inside of a function.

This conveys what I’d like to accomplish:

function SetColorscheme (colorscheme)
  set colorscheme a:colorscheme
  hi Normal ctermbg=NONE
  hi LineNr ctermbg=NONE
endfunction

And I’m currently calling it like this:

:call SetColorscheme ('wombat256')

Currently vim is complaining about missing parentheses.

What’s the correct syntax for what I’m trying to do here?

Answer 1

colorscheme is not an option you use with the set command, it’s a command of its own. So try this for the colorscheme line:

execute 'colorscheme ' . a:colorscheme
