vic / clap-nix Goto Github PK

Eg, -h is same than --help

Since clap-nix is implemented in Nix, it will always need a Nix interpreter to work. However there would be some benefit on creating an external interface (a nix-clap command perhaps) that you could use from the shell and get the resolved options output either in another nix file or json or anything that nix can write to.

Since nix options are self-documenting, it would be nice to be able to output help in various formats: plain-text (for showing as part of --help), as a file for man(1) for longer documentation, as json for processing from other tools.

At least plain text should be implemented.

Currently if you select a command options from their parent commands are no longer recognized. This should not be case since, for example the following should be possible:

mycmd foo --enable-x bar --enable-y <=> mycmd foo bar --enable-x --enable-y

and clap-nix should automatically know that enable-x belongs to the foo command (only if there's not an enable-x in bar itself.

Change the enabled flag to be true only if anything inside the command was explicitly set by the user. Or perhaps this should be another flag ?
