wal.vim includes a color scheme for lightline, but it only plays nicely
with neovim. This commit conditionally loads the wal color scheme since
using it in vim will throw multiple errors.
Previously I separated my .vimrc into multiple files in attempt to
organize it. Now that I know more about vim, however, using only one
config file leads to less moving parts. Additionally, I now use less
vim settings altogether since I frequently have to work on foreign
machines, which probably won't have my .vimrc anyway.
pywal (also known as wal) lets us change color schemes with a cache
directory instead of editing config files directly. This helps us
separate the dotfiles from the color schemes.
This commit removes explicit color settings from my dotfiles, which are
now managed by pywal. Dunst has been added to show any notifications
that I may want to use in the future. The colors.Xresources file is used
to prevent urxvt from using a depth of 32.
My custom colors.vim file has been removed in favor of wal.vim, which
solves some problems I had to manually resolve myself and should make
things easier to maintain in the long term.
Note that pywal also supports base16 color schemes, as well as any other
color scheme you can think of.
Instead of stowing dotfiles individually by software, and instead of
stowing dotfiles based on working environment, I now just stow all
dotfiles at once, so the extra hierarchy isn't needed.
