crabmail VS cli-guidelines

You may be interested in `arg.rs`, which isn't a library, just some code snippets I use to write command line parsers. Here's an example: https://github.com/alexwennerberg/crabmail/blob/main/src/arg.rs

The Command Line Interface Guidelines [1] says:

> Do not read secrets from environment variables

> Secrets should only be accepted via credential files, pipes, `AF_UNIX` sockets, secret management services, or another IPC mechanism

Which one of these do you use? On github it seems common for projects to use environment variables for secrets.

[1] https://clig.dev/#environment-variables

Seems they took a small step back from their previous "don't bother with man pages" stance. Now it's "Consider providing man pages."

I still find it a rather shocking order of priority, honestly.

- E. `blah project foo --edit`

Wondering if there was any guidance on this from the UNIX people. Perhaps scoping should be done using the file system. `cd path/to/project && blah edit`. Like git does with `git --cwd=path/to/project`. Maybe a virtual FS could even be used. Then you wouldn't have to continuously type in the scope with each command. Interesting thinking about how to maintain state in the terminal...thinking about how Python's virtual env bin/activate modifies the shell.

Found an interesting guide here: https://clig.dev/

Capturing these guidelines is one of the primary reasons that https://clig.dev/ exists.

You may want to take a look at various existing CLIs to get inspiration on how they operate, the user feedback loop and the ergonomics on using them. Here is a great website on some CLI structing guidance https://clig.dev/
