mcfly VS direnv

It is a custom pretrained NN with very few nodes, the full source code is here: https://github.com/cantino/mcfly/blob/master/src/network.rs

I've had a great time using McFly (https://github.com/cantino/mcfly) for going through my command history. It prioritizes showing commands that were previously run in your current directory!

I end up installing mcfly (https://github.com/cantino/mcfly) in all my shells, and it works great in fish as well.

You should try https://github.com/cantino/mcfly, it replaces the Ctrl r bind for fuzzy-search-style patter matching, that you can see all the similar commands and then select the one you want, it has been on all my machines ever since I've learnd of it

There's also McFly which does the same thing.

I've only used McFly and found it to be pretty great. My only complaint is the default search mode is SQL strings, so you have to use `%` for wildcards. I wish it was a more forgiving, less exact search.

Has anyone used both and could compare them?

If you like searching your Bash history with fzf, you're gonna love McFly: https://github.com/cantino/mcfly

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.

The more applications I write, the more I tend to avoid typical config files in favor of using direnv [0] to set environment variables.
