help/1 in the REPL?

[oubiwann]

Do you think it would be possible to, in addition to the already-supported help/0 in the REPL, to have a help/1 for displaying module man pages?

> (help io_lib)

It would be possible if the man pages are downloaded into the "right places", otherwise not.

What about being able to printing out the docstring of a function via help/1?

EDIT: Nevermind, I just saw the referenced issues: #87 and #67

[oubiwann]

I think I like the idea of help/2 and help/3 as names, instead of describe. help/1 could even be used to get the help of REPL functions. This last would require that the help text for each REPL function be stored somewhere (perhaps in lfe_shell using the docstring module attributes, as proposed in the other ticket?). It would also mean that the output for help/0 could be generated automatically ...

Lots of good work has gone into a solution for this problem; with LFE 2.0 we're even going to have support for Elixir docs metadata, etc.
