ajjackson's new dotfiles

Declaring bankruptcy and starting again

Things that worked well last time

  • Org-babel

    • One file for emacs config and one file for everything else actually seemed to be a decent way of dividing

  • Using one repository that works for multiple machines (as opposed to previous effort with Git branches)

Things to try differently

  • Public on Github instead of private on bitbucket

    • Bitbucket's new authentication setup is really cumbersome for something I want to clone quickly on a new system and push changes from.
    • I don't really have any secrets in here anyway?

  • Ditch the email stuff. I really did prefer notmuch to webmail, but every other aspect of configuration was too painful to keep up, and most of my accounts use Exchange now :-(

  • Use elisp to conditionally tangle different stuff on different machines. I was finding it a bit tricky to specify the different use-cases / environments in previous hackery, the extra power should be helpful

  • Don't name the setup script setup.py, that was really confusing because of Python conventions

  • Use stow to distribute files that have system-dependent locations:

    • org-babel can tangle to a standard tree within a temporary director or this source folder
    • then call stow -t /suitable/root/position [packages] to copy them
    • --dotfiles argument automatically converts "dot-config" to ".config" etc for a nicer tree

  • Use Elpaca instead of package.el

    • soooooo much faster
    • install unavailable packages by default, if it shouldn't be on this machine then don't configure it (see conditional tangling, above...)

Things that remain a bit of a headache

  • It would be really nice if stow could easily be diffed against the current version. Maybe some kind of --dryrun/--diff mode can be added to make.el that handles this. Would need to:

    • Copy current stow files to a temporary directory
    • Re-stow from the temporary directory
    • Tangle files (which is hard-coded to the "main" stow path)
    • Diff the temporarary (and still-live) version with the new tangle
    • Clean up by deleting the newly-tangled files, moving back the temporary stow tree and re-linking everything to the normal path.

  • That would be made a lot easier by putting all the stow directories under a folder rather than using the main source directory. It also makes it easier to .gitignore them?

Instructions

  • For i3 I put a few scripts into ~/.local/bin; make sure those are visible. (i.e. add ~/.local/bin to PATH in ~/.profile)

  • ./make.el to tangle dotfiles to directories

  • stow -t $HOME --dotfiles i3 fish ... to symlink things to ~/.config and ~/.local/bin

    • Once there are more packages and machines set up, this should be included in make.el, fired off by an optional argument.

  • The dotfiles feature is busted on most builds of GNU stow, we need to use a fork for this name conversion to work properly.

    git clone https://github.com/ajjackson/stow.git
cd stow
git fetch origin bug-56727
git checkout bug-56727
autoreconf -iv
./configure --prefix=$HOME/opt/stow --with-pmdir=$HOME/opt/stow
make

    builds stow under ~/opt/stow

    • To run the tests we need some other Perl modules installed

      cpan
> install Test::Output
> install Test::More
> install IO::Scalar

      Then make test should work.

Containers

WIP: container can be used to test how this works in a clean environment

Currently, build with

    podman build --tag dotfiles --file containers/micromamba --format Docker .

and run with

    podman run -it --rm dotfiles

Note that I am using a slightly old Ubuntu base for compatibility with conda-forge emacs build.
