I'm writing a command line program with Haskell and cmd-args with the Explicit module.
The Implicit module provide a default help message with a list of differents modes with the common flags to these modes, like this :
diffy [COMMAND] ... [OPTIONS]
Create and compare differences
Common flags:
-o --out=FILE Output file
-? --help Display help message
-V --version Print version information
diffy create [OPTIONS]
Create a fingerprint
-s --src=DIR Source directory
diffy diff [OPTIONS] OLDFILE NEWFILE
Perform a diff
Is it possible to make the same thing with the Explicit module ?
Is there a function in cmdargs giving the commons flags of several modes ?
