Issue 416 - Help subcommand accepts other subcommands as arguments #450
Conversation
… help subcommand The `help` subcommand can now accept other subcommands as arguments to display their help message. This is similar to how many other CLIs already perform. For example: ``` $ myprog help mysubcmd ``` Would print the help message for `mysubcmd`. But even more, the `help` subcommand accepts nested subcommands as well, i.e. a grandchild subcommand such as ``` $ myprog help child grandchild ``` Would print the help message of `grandchild` where `grandchild` is a subcommand of `child` and `child` is a subcommand of `myprog`.

Thank you! I ❤️ love ❤️ this feature! One tiny complaint is that the help message looks a bit awkward. Shouldn't help messages aim to fit nicely in 80 columns without wrapping? |
|
@crumblingstatue It should wrap nicely at term width (which is not necessarily 80) unless running it in Windows. However, I also think it should be shorter. how about: |
|
@sru yeah we can shorten it to that wording and I'm fine with that since I think it's a little long too. @crumblingstatue if you're not disabling the default cargo features or running Windows it should wrap at the term width...although I think adding a setting to wrap at a specified width regardless would be great too. I'll add a new issue to track that once I get home if someone hasn't already done it. |
