Generated Lightline colorscheme names differ from base16-vim names due to conversion of hyphens to underscores

[antoineco]

Right now, it is not possible to set g:lightline['colorscheme'] directly to the value of g:colors_name, because the Mustache template substitutes hyphen characters with underscores in the name of generated files:

base16-vim-lightline/templates/default.mustache

Line 41 in cea11b7

let g:lightline#colorscheme#base16_{{scheme-slug-underscored}}#palette = lightline#colorscheme#flatten(s:p)

(in the postbuild script as well)

base16-vim does not perform such conversion, which result in different names between the two projects:
https://github.com/fnune/base16-vim/blob/dd770de2790ef42f260a79878f1dee131d2e3d7d/templates/default.mustache#L148

I was wondering whether this was intentional, since this conversion requires another substitution in order to be able to automatically set the Lightline colorsheme to the current Vim colorscheme, which might be avoidable.

Example:

let g:lightline = {
    \ 'colorscheme': substitute(g:colors_name, '-', '_', 'g')
    \ }
