I am on neovim with Oni. vim-netranger plugin uses terminal colors in this format to highlight things. It does work in terminal with neovim , but not in a gui app.

I am looking for a way to replace this that will work.

def c256(msg, c, background):
    if background:
        return '[38;5;{};7m{}[0m'.format(c, msg)
    else:
        return '[38;5;{}m{}[0m'.format(c, msg)

This string is printed into a line(in a buffer) somehow.

Thanks

Those are ANSI escape sequences which are commonly used to print colored text in terminal windows. If valid sequences are being inserted into Vim buffers then you'll be happy to know that there's a plugin that will translate to Vim highlighting/colors: AnsiEsc

Here's are basic examples of the concepts...


Using something close to one of your samples this shows what happens on shell command line...

Now if we redirect the printf output to a file and open with generic Vim we see...

With plugin installed just run command :AnsiEsc and you get...

Assuming by text line OP means the command line window (e.g., via echom), use :echohl to set the colors and :echom to print strings.

Note that echohl uses the available highlight groups; you may want to use execute and highlightto create your own from function arguments if custom highlights are needed. Otherwise, just lean on the provided groups and trust the colorscheme.

For a buffer you need to use custom syntax commands, or borrow an existing syntax.

See the relevant docs.

I ask it also here

https://github.com/ipod825/vim-netranger/issues/22

and what he wrote is:

I now see that this is because I didn't set the highlit color for gui in the syntax file. The line should be modified to something like:

 'hi NETRhi'.c.' ctermfg='.c.' ctermbg=None guifg=#rrggbb guibg =None'

It is working now.
