dotfiles VS direnv

chezmoi (<https://chezmoi.io> or <https://github.com/twpayne/chezmoi>) has a couple dozen txtar tests. They are both amazing and completely frustrating to use, but I don't think that there would be a better way to test most of what chezmoi does without them.

Tom Payne (the creator and primary developer of chezmoi) has added some extra commands to the txtar context which makes things easier for certain classes of testing.

You can configure Hammerspoon so a hot key combination puts a window in a defined section of the screen. For example, I use Ctrl+Alt+H to put the current window in the left half of the screen, Ctrl+Alt+L for the right half, Ctrl+Alt+Enter for full screen, etc. This makes arranging your windows very fast.

I think direnv already does a good job in this space, and it's already available in your package manager.

I switched from asdf to mise after a comment on lobste.rs[1] suggested I do so a few months ago, and I have been very happy with it.

It sands off some of asdf's sharp UI edges and provides a somewhat larger but still reasonable feature set; I've also replaced most of my direnv[2] usage with it.

The mise -> asdf comparison page is useful[3]

I also made the export diff configurable, motivated by this post: https://github.com/direnv/direnv/pull/1233

Nice.

For years I've been using [direnv](https://direnv.net/) for this, setting environment variables which git picks up. This looks like a more feature complete equivalent, although to be honest I only really need switching of committer email and the SSH key used.

Direnv, for the uninitiated, loads and unloads environment variables when directories are entered and exited. Under every project folder there is a `$PROJ_DIR/.envrc` which contains:

buffer-env: A pure-Elisp version of the direnv utility. Useful to make Emacs aware of Python virtualenvs (which, judging by the questions posted here, is unfortunately still a complication for a lot of people). Similar to (and inspired by) envrc, but doesn't require the direnv program.

You can look at direnv to see this in action as they wrote shell hooks that get loaded into the shell profile and are executed on every prompt. https://direnv.net/

Yes, most Nix users employ https://direnv.net or the equivalent for your IDE of choice. Emacs for instance has https://github.com/purcell/envrc which set per-buffer variables.
