Group options and arguments by topic

[john-cd]

[nitpick] too many commands

1. Group options by topic when running just --help from the command line
2. Same thing with commands

a) recipe listing / selection --choose --list --groups --summary

b) justfile formatting / checking --fmt --check

c) justfile management --init --dump --edit

d) variables --variables --evaluate

e) help --help --changelog --man

f) others --version --completions

[casey]

I think that's pretty reasonable. There's a help_heading feature that clap provides, that we already use to separate commands from other options, so this would just require using different headings for the different groups of commands.

[john-cd]

Part of the confusion is that commands look like options. Thinking loud, could commands behave like built-in recipes??

just --sys help just --sys list just --sys init ...

[casey]

It would be pretty annoying to have to type --sys. Also, this would be a very disruptive breaking change.

[john-cd]

Yeah, I agree

[prathyk]

It would be nice to have a different command for managing just and another command for running recipes justrun.

Would have justrun as a separate command ease the user experience for #476

Because most of the options of the just command are about managing just or justfiles etc. If we have a dedicated justrun, then have options/flags, commands and subcommands(using modules) etc...?
