Add ability to use colorscheme in lightline

[mambusskruj]

Hi!

Lightline is a popular light and configurable statusline/tabline plugin for Vim. – https://github.com/itchyny/lightline.vim

Lightline provides ability to configure colors for theme developers. Here's example for popular vim theme called gruvbox: https://github.com/morhetz/gruvbox/blob/master/autoload/lightline/colorscheme/gruvbox.vim

Would you mind to add colors for lightline in yui?

I really enjoy your theme, btw!

Glad you like it 👍🏻 thank you. Sounds like a reasonable request I'll try to take care of it ASAP

[cideM]

I started working on this and I'll have a branch ready for you to try tomorrow, sorry for the delay

There's a lightline branch which you can test with

let g:yui_lightline = v:true
let g:lightline = {}
let g:lightline.colorscheme = 'yui'
call lightline#init()
call lightline#colorscheme()
call lightline#update()

Hey! Hmm, I get error:

lightline.vim: Could not load colorscheme yui.

I see lightline block in colors/yui.vim

UPD: Ah, I get it now!

Looks good!

Personally I'm not sure about bold text. For reference, lightline's solarized theme doesn't use any bold text, and it looks sharper to me. https://github.com/itchyny/lightline.vim#solarized-backgroundlight

But it's all of your taste ofc. :) So for me it already looks very nice!

I agree that the solarized theme without bold text looks better. I'll take another look and tweak some colors and remove the bold, just need to make sure that contrast is good enough

@mambusskruj I pushed another commit to the branch which removes the bold

[mambusskruj]

Love it! Thank you, it looks very clean and pretty.

@mambusskruj I updated the documentation and made sure that the colorscheme uses the documented option. Would it be possible for you to check this again? I verified that the colorscheme works with and without lightline and that people can still use other lightline color schemes even when yui_lightline = v:true

I'll merge this soon then.

g:yui_lightline

• v:false (default): do not register the yui palette with lightline
• v:true: register the yui palette with lightline. You still need to set the lightline color scheme to yui.

let g:yui_lightline = v:true
colorscheme yui
let g:lightline = {
  \ 'colorscheme': 'yui'
  \ }

Would it be possible for you to check this again?

Checked it. Yes, it works as you described it!
