### All contributions are very welcome but themes/ extensions require a lot of work on my part if not done properly so here's a guide on how to do them.
|
|
|
|
### Adding a theme
|
|
|
|
* refer to example below to see how themes are defined
|
|
* take 4 screenshots showing a different vim modes (normal, insert, visual, replace)
|
|
* add your theme with screenshots attached to [THEMES.md](./THEMES.md) while maintaining alphabetical order
|

To create a custom theme you need to define a colorscheme for each of vim's modes. Each mode has a `fg` and `bg` field for every lualine section.
|
|
This is really easy in lua. Here is and example of a gruvbox theme.
|
|
|
|
```lua
|
|
local gruvbox = { }
|
|
|
|
local colors = {
|
|
black = "#282828",
|
|
white = '#ebdbb2',
|
|
red = '#fb4934',
|
|
green = '#b8bb26',
|
|
blue = '#83a598',
|
|
yellow = '#fe8019',
|
|
|
|
gray = '#a89984',
|
|
darkgray = '#3c3836',
|
|
|
|
lightgray = '#504945',
|
|
inactivegray = '#7c6f64',
|
|
}
|
|
|
|
gruvbox.normal = {
|
|
a = {
|
|
bg = colors.gray,
|
|
fg = colors.black,
|
|
},
|
|
b = {
|
|
bg = colors.lightgray,
|
|
fg = colors.white,
|
|
},
|
|
c = {
|
|
bg = colors.darkgray,
|
|
fg = colors.gray
|
|
}
|
|
}
|
|
|
|
gruvbox.insert = {
|
|
a = {
|
|
bg = colors.blue,
|
|
fg = colors.black,
|
|
},
|
|
b = {
|
|
bg = colors.lightgray,
|
|
fg = colors.white,
|
|
},
|
|
c = {
|
|
bg = colors.lightgray,
|
|
fg = colors.white
|
|
}
|
|
}
|
|
|
|
|
|
gruvbox.visual = {
|
|
a = {
|
|
bg = colors.yellow,
|
|
fg = colors.black,
|
|
},
|
|
b = {
|
|
bg = colors.lightgray,
|
|
fg = colors.white,
|
|
},
|
|
c = {
|
|
bg = colors.inactivegray,
|
|
fg = colors.black
|
|
},
|
|
}
|
|
|
|
gruvbox.replace = {
|
|
a = {
|
|
bg = colors.red,
|
|
fg = colors.black,
|
|
},
|
|
b = {
|
|
bg = colors.lightgray,
|
|
fg = colors.white,
|
|
},
|
|
c = {
|
|
bg = colors.black,
|
|
fg = colors.white
|
|
},
|
|
}
|
|
|
|
gruvbox.command = {
|
|
a = {
|
|
bg = colors.green,
|
|
fg = colors.black,
|
|
},
|
|
b = {

c = {

fg = colors.black
|

},
|
|
}
|
|
|
|
gruvbox.terminal = gruvbox.normal
|
|
|
|
gruvbox.inactive = {
|
|
a = {
|
|
bg = colors.darkgray,
|
|
fg = colors.gray,
|
|
},
|
|
b = {

|

fg = colors.gray,
|
|
},
|
|
c = {
|
|
bg = colors.darkgray,
|
|
fg = colors.gray
|
|
},
|
|
}
|
|
|

lualine.theme = gruvbox
