" Each theme is contained in its own file and declares variables scoped to the
" file. These variables represent the possible "modes" that airline can
" detect. The mode is the return value of mode(), which gets converted to a
" readable string. The following is a list currently supported modes: normal,
" insert, replace, visual, and inactive.
" Airline themes are generated based on the following concepts:
" * The section of the status line, valid Airline statusline sections are:
" * airline_a (left most section)
" * airline_b (section just to the right of airline_a)
" * airline_c (section just to the right of airline_b)
" * airline_x (first section of the right most sections)
" * airline_y (section just to the right of airline_x)
" * airline_z (right most section)
" * The mode of the buffer, as reported by the :mode() function. Airline
" converts the values reported by mode() to the following:
" * normal
" * insert
" * replace
" * visual
" * inactive
" The last one is actually no real mode as returned by mode(), but used by
" airline to style inactive statuslines (e.g. windows, where the cursor
" currently does not reside in).
" * In addition to each section and mode specified above, airline themes
" can also specify overrides. Overrides can be provided for the following
" scenarios:
" * 'modified'
" * 'paste'
"
" Each mode can also have overrides. These are small changes to the mode that
" don't require a completely different look. "modified" and "paste" are two
" such supported overrides. These are simply suffixed to the major mode,
" separated by an underscore. For example, "normal_modified" would be normal
" mode where the current buffer is modified.
" Airline themes are specified as a global viml dictionary using the above
" sections, modes and overrides as keys to the dictionary. The name of the
" dictionary is significant and should be specified as:
" * g:airline#themes#<theme_name>#palette
" where <theme_name> is substituted for the name of the theme.vim file where the
" theme definition resides. Airline themes should reside somewhere on the
" 'runtimepath' where it will be loaded at vim startup, for example:
" * autoload/airline/themes/theme_name.vim
"
" The theming algorithm is a 2-pass system where the mode will draw over all
" parts of the statusline, and then the override is applied after. This means
" it is possible to specify a subset of the theme in overrides, as it will
" simply overwrite the previous colors. If you want simultaneous overrides,
" then they will need to change different parts of the statusline so they do
" not conflict with each other.
"
" First, let's define an empty dictionary and assign it to the "palette"
" variable. The # is a separator that maps with the directory structure. If
" you get this wrong, Vim will complain loudly.
" For this, the dark.vim, theme, this is defined as
let g:airline#themes#dark#palette = {}
" First let's define some arrays. The s: is just a VimL thing for scoping the
" variables to the current script. Without this, these variables would be
" declared globally. Now let's declare some colors for normal mode and add it
" to the dictionary. The array is in the format:
" [ guifg, guibg, ctermfg, ctermbg, opts ]. See "help attr-list" for valid
" values for the "opt" value.
let s:N1 = [ '#00005f' , '#dfff00' , 17 , 190 ]
let s:N2 = [ '#ffffff' , '#444444' , 255 , 238 ]
let s:N3 = [ '#9cffd3' , '#202020' , 85 , 234 ]
let g:airline#themes#dark#palette.normal = airline#themes#generate_color_map(s:N1, s:N2, s:N3)
" Keys in the dictionary are composed of the mode, and if specified the
" override. For example:
" * g:airline#themes#dark#palette.normal
" * the colors for a statusline while in normal mode
" * g:airline#themes#dark#palette.normal_modified
" * the colors for a statusline while in normal mode when the buffer has
" been modified
" * g:airline#themes#dark#palette.visual
" * the colors for a statusline while in visual mode
"
" Values for each dictionary key is an array of color values that should be
" familiar for colorscheme designers:
" * [guifg, guibg, ctermfg, ctermbg, opts]
" See "help attr-list" for valid values for the "opt" value.
"
" Each theme must provide an array of such values for each airline section of
" the statusline (airline_a through airline_z). A convenience function,
" airline#themes#generate_color_map() exists to mirror airline_a/b/c to
" airline_x/y/z, respectively.
" The dark.vim theme:
let s:airline_a_normal = [ '#00005f' , '#dfff00' , 17 , 190 ]
let s:airline_b_normal = [ '#ffffff' , '#444444' , 255 , 238 ]
let s:airline_c_normal = [ '#9cffd3' , '#202020' , 85 , 234 ]
let g:airline#themes#dark#palette.normal = airline#themes#generate_color_map(s:airline_a_normal, s:airline_b_normal, s:airline_c_normal)
" It should be noted the above is equivalent to:
" let g:airline#themes#dark#palette.normal = airline#themes#generate_color_map(
" \ [ '#00005f' , '#dfff00' , 17 , 190 ], " section airline_a
" \ [ '#ffffff' , '#444444' , 255 , 238 ], " section airline_b
" \ [ '#9cffd3' , '#202020' , 85 , 234 ] " section airline_c
" \)
"
" In turn, that is equivalent to:
" let g:airline#themes#dark#palette.normal = {
" \ 'airline_a': [ '#00005f' , '#dfff00' , 17 , 190 ], "section airline_a
" \ 'airline_b': [ '#ffffff' , '#444444' , 255 , 238 ], "section airline_b
" \ 'airline_c': [ '#9cffd3' , '#202020' , 85 , 234 ], "section airline_c
" \ 'airline_x': [ '#9cffd3' , '#202020' , 85 , 234 ], "section airline_x
" \ 'airline_y': [ '#ffffff' , '#444444' , 255 , 238 ], "section airline_y
" \ 'airline_z': [ '#00005f' , '#dfff00' , 17 , 190 ] "section airline_z
" \}
"
" airline#themes#generate_color_map() also uses the values provided as
" parameters to create intermediary groups such as:
" airline_a_to_airline_b
" airline_b_to_airline_c
" etc...
" Here we define overrides for when the buffer is modified. This will be
" applied after g:airline#themes#dark#palette.normal, hence why only certain keys are
