[erlang-questions] cover & export_all
Wed Jul 10 01:34:29 CEST 2013
You are right, while cover compiling from source works (you can use this as
> cover:compile(cover_test, UserOptions = [export_all, debug_info]).
(because UserOptions from the arguments is taken when cover recompiles the
when cover compiling from beam UserOptions =  is taken.
This could be fixed in cover by taking the compile options from the beam
file as you assumed how it works.
Actually the documentation still says that "Only options defining include
file directories and macros are passed to compile:file/2, everything else
is ignored." apparently a patch from Tobias Schlager added export_all to
the allowed options of cover:compile for the exact same use case as you
had. But this is missing from cover:compile_beam.
May be I try to come up with a patch
