vim-addon-local-vimrc VS direnv

You can? I'd never heard of this. Until now, I'd always used MarcWeber/vim-addon-local-vimrc. It works okay but if there's something built-in I'd much prefer that.

https://github.com/MarcWeber/vim-addon-local-vimrc does the job just fine.

Project-specific editor config: vim-localvimrc, vim-addon-local-vimrc

vim-addon-local-vimrc (project-local settings in a secure way, never use project-local settings without)

VERY IMPORTANT: Do not set your Neovim to automatically load such a file. Vim script files contain executable code and you do not want to load executable code unconditionally, that's a massive vulnerability. And no, setting the secure option does not help. I use this plugin which makes me first confirm that I want to load the file. From then on it will only automatically load the file if it has not been changed. If the file has changed it will prompt me again.

Try vim-addon-local-vimrc to load a project specific vimrc or vim-ctrlspace to load session infos.

I like monotasking - no plugins eating up screen real estate - so I use [vim-projectionist](https://github.com/tpope/vim-projectionist) and [vim-addon-local-vimrc](https://github.com/MarcWeber/vim-addon-local-vimrc). Projectionist allows me to capture the structure of my project: 'view', 'controller', 'test', 'component', 'feature-x-component', whatever. vim-addon-local-vimrc lets me configure projectionist (and other vim plugins) for my particular project.

Plugin: vim addon local vimrc

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.
