Transparent background, cursor_column background and selection background options

[Dave-Elec]

Added transparent background which can be set by

let g:gruvbox_transparent_bg=1

Added cursor_column background option which can be set by

let g:gruvbox_cursor_column=<color_name>

Added selection background option which can be set by

let g:gruvbox_selection_bg=<color_name>

@morhetz could you please take a look?

i'm using this branch a while to get the transparent background and from my point of view, it looks good!
thank you @Dave-Elec

[areisrosa]

Working perfectly for me now!
Thanks @Dave-Elec

[Dave-Elec]

Thanks, Glad it helped.

So, are you going to merge it?

This is a great idea, although unfortunately this fails for me in both nvim-qt and gvim in windows (background becomes a solid colour dictated by background value).

Thanks, @Dave-Elec ! This worked for me in nvim.
Using nvim-gtk or gnvim both this and the command on #96 don't work.

When this background is activated, some color's change on airline/tabline.

@saragiotto Try putting colorscheme gruvbox after gruvbox settings.

Sorry, I don't use gruvbox anymore (currently using gruvbox-material) so I can't test it.

I also had the same issue with g:gruvbox_transparent_bg this works fine in Mac's terminal (first screenshot) but creates problems in item (second screenshot)

I answered this on stack over flow - https://stackoverflow.com/a/67569365/14526555. copy-pasting from there.

    " Workaround for creating transparent bg
    autocmd SourcePost * highlight Normal     ctermbg=NONE guibg=NONE
            \ |    highlight LineNr     ctermbg=NONE guibg=NONE
            \ |    highlight SignColumn ctermbg=NONE guibg=NONE

People on internet has similar thing with VimEnter instead of SourcePost. VimEnter solves this problem partially and creates prblem when we source again (therefore SourcePost)

Final Results on iterm
