An automated way to convert a vim GUI color scheme to work with 256-color vim?

Question

I only have a graphical VIM graphical interface that I would like to convert to a 256-color version. Is there an automated way to do this?

Googling found only http://www.vim.org/scripts/script.php?script_id=1809 that didn’t work for me (the colors turned out to be completely wrong) and was not really intended to be converted and reused, but rather for conversions on the fly.

Answer 1

You can use CSApprox , which is a plugin that converts GUI color schemes to terminal color schemes.

I tried this once or twice, and the result was acceptable.

Answer 2

I use gnome-terminal and just add

set t_Co=256 

in my .vimrc file made all the difference

Answer 3

here is a simple python script that will do the conversion for you:

 '''add terminal color values to a GUI only colorscheme''' # USAGE: vim_colorscheme_convert.py <colorscheme_file> import sys import re # requires path.py: https://pypi.python.org/pypi/path.py from path import path # requires colortrans.py: https://gist.github.com/MicahElliott/719710 from colortrans import rgb2short HI_LINE = 'hi %(name)s guifg=%(guifg)s guibg=%(guibg)s gui=%(gui)s ctermfg=%(ctermfg)s ctermbg=%(ctermbg)s cterm=%(cterm)s' f = path(sys.argv[1]) if not f.isfile(): print('File does not exist: %s' % f) sys.exit(-1) output = [] for line in f.lines(): m = re.match('hi\s+(?P<name>\w+)\s+.*$', line) if not m: # append non "hi" lines verbatim output.append(line) else: values = {'name': m.group('name')} for val in ('', 'fg', 'bg'): m = re.search('gui%s=(?P<gui%s>\S+)' % (val, val), line) if not m: values['gui%s' % val] = 'NONE' values['cterm%s' % val] = 'NONE' else: values['gui%s' % val] = m.group('gui%s' % val) if not values['gui%s' % val].startswith('#'): values['cterm%s' % val] = values['gui%s' % val] else: values['cterm%s' % val] = rgb2short(m.group('gui%s' % val).strip('#'))[0] output.append(HI_LINE % values) # make a back up of the original and write the new contents f.copy('%s.bak' % f) f.write_lines(output)
