Bring Vim9 Variable Arguments to airline/themes

[igbanam]

Vim9 now has variable arguments :h vim9-variable-arguments. This change refactors the current capabilities with vim9script variable arguments.

Now, there is no easy way to test this. I had to

• clone vim-airline
• use the local copy as my plugin — Plug ~/path/to/locally-clonned/vim-airline
• for every change…
  • copy-paste the scenarios into an echo to check that the refactor works as should

I had to resort to this sort of testing because thinca/vim-themis#74 is yet unresolved.

My test cases are below

generate_color_map with 6 variables

:echo airline#themes#generate_color_map([ 1, 1, 1, 1, '1' ], [ 2, 2, 2, 2, '2' ], [ 3, 3, 3, 3, '3' ], [ 4, 4, 4, 4, '4' ], [ 5, 5, 5, 5, '5' ], [ 6, 6, 6, 6, '6' ])

generate color_map with 3 variables

:echo airline#themes#generate_color_map([ 1, 1, 1, 1, '1' ], [ 2, 2, 2, 2, '2' ], [ 3, 3, 3, 3, '3' ])

get_highlight with extra arguments

:echo airline#themes#get_highlight('Foo', 'bold', 'italic')

get_highlight2 with extra arguments

:echo airline#themes#get_highlight2(['Foo','bg'], ['Foo','fg'], 'italic', 'bold')
