Improved AnsiEsc.vim

Files with ANSI escape sequences look good when dumped onto a terminal that accepts them, but have been a distracting clutter when edited via vim. The AnsiEsc.vim file, when sourced, will conceal Ansi escape sequences but will cause subsequent text to be colored as the escape sequence specifies.

This is a Vim script №302: AnsiEsc.vim updated to latest author's version with several fixes/improvements.

Now with custom colors!

Changing Colors

" Returns the #rrggbb hex value for a HL group.

" @function GetHLHex
" @description Returns the #rrggbb hex value for a HL group.
" @param group The highlight group to get. e.g. 'Comment'
" @param ground The value to get ('fg' or 'bg').
" @return The #rrggbb color value.
function! GetHLHex(group, ground)
    " Get the syntax ID of the highlight group
    let syn_id = synIDtrans(hlID(a:group))

    " Get the RGB values of the foreground color in GUI mode
    let hex_color = synIDattr(syn_id, a:ground . '#')

    " Return the hex color
    return hex_color
endfunction
