This commit adds fish support for the other functions I used to use in
zsh. Since my dotfiles are now separated by environment, it's easy to
see which environment depends on which dotfiles, instead of stowing them
one by one based on software name.
Really, there is no reason to use zsh when fish exists, at least not for
my use case. Maintaining one set of shell config files is easier than
two, so I'm removing the zsh files.
Some other changes in this commit include:
- The addition of the current user and hostname to the fish prompt
- The addition of some zsh functions I re-implemented in fish
- The removal of the dircolors file (not needed with exa anyway)
- The removal of some aliases I never used
-
It doesn't make sense to manage an entire neofetch config file since the
majority of the settings required to produce a decent output can be
achieved by just passing options at runtime.
