[erlang-bugs] R16 EUnit *** context setup failed ***

[Diego Llarrull]

Hello everyone,

I'm working on a riak_core based project, that is, one which uses rebar 
+ GNU make and where the src files are located  in different folders 
than the beam files, which are inside inside zipped (.ez) files.

sync + libnotify will do the trick for unzipped files, but some extra 
trickery was needed to load the new .beam files

a) compile the modified sources
b) (create and) run a script that generates the .zip files containing 
the .beams and deploys those files in their destination directory
c) run the following code:

reload() ->
	Modules = [ X || {X,L} <- code:all_loaded(), is_list(L),string:str(L, 
?PATH_TO_CODE_DIR) =/= 0],
	lists:map(fun(X) -> c:l(X) end, Modules).

Hope this helps anyone, right now I'm trying out ssync to see if it is 
able to handle zipped files.

Best regards,

Diego
