Erlang dialyzer from werl.exe?

Question

I tried running dialyzer --help from the werl command line and it hung. Am I missing something? Is it only available for the dos shell (I'm on XP SP3)?

Answer 1

It is possible to run dialyzer from within the Erlang shell (and thus, I assume, werl) but the way you attempted to invoke it is only appropriate for the DOS shell.

See Using the Dialyzer from Erlang near the bottom of http://www.erlang.org/doc/man/dialyzer.html
