This is a preparation to start experimenting with zsh. The idea is to
share the aliases and environment setup between both shells to avoid
having a bunch of duplication. Even if I decide to stick with zsh it
would be nice to keep the bash configs around for systems where I might
not want to install zsh for some reason. We'll see how this goes...
This makes the common actions previously encoded as bash aliases
independent of the shell (I'm using /bin/sh for the scripts), which will
make a potential switch to zsh easier by having less bash-specific stuff
around.
The solarize script evalss the output of the dircolors(1) but the
LS_COLORS variable gets exported in its environmnent, not the calling
shell where we actually need it so ls(1) and other programs wiill
inherit it.
Therefore, the evaluation of the dircolors(1) output is moved to the
change_bg() function in the shell, so that the LS_COLORS variable is
available to any children of the shell.
The reason why I had missed this is that in most systems I have ls
aliased to exa, which does not care about LS_COLORS and has its own
coloring system. On cygwin, however, exa is not available and I noticed
that the colors were missind; and indeed, on systems with exa the colors
are also missing if I run ls as \ls.
