These are my dotfiles. There are many like them, but these are mine.
They're set up for elaborate color prompts, bash, zsh, emacs, python and git, and work on Linux (Ubuntu, Debian, possibly Fedora, Mint) and macOS. Parts of them probably originated on a 4.2bsd VAX 11/780 and a 3b2 running System V in the early 80s, but like Abe Lincoln's axe, the handle has been replaced three times and the head twice.
./setup.sh && make
Any existing (non-symlink) dotfiles will be set aside and symbolic links will be created that point to these dotfiles. So keep them checked out. "make clean" will delete emacs cruft in this directory. "make really-clean" will delete the set aside files from your home directory, PLUS any emacs cruft in this directory.
To install on macOS, you'll need to install the XCode command line tools, but I usually already have XCode installed. Sometimes the script will seem to hang as it pops up the UI for accepting the XCode EULA.
Setup.sh && make should be "idempotent," i.e., you should be able to
run them as often as you like without breaking anything.
I want to install emacs 28 everywhere to avoid flapping of (quote
vs. ' in emacs lisp files.
Now that setup.sh can check for previously installed packages, I'm kind of moving away from installing stuff with the Makefile and just having setup.sh install everything.
