I know it's possible to use gitk for that, but most the time I use the console to build and test Wings3D that I prefer to not start an IDE just for manage the branches. It's like to say a Linux user to use a graphic file manager instead of to use the shell.
I'm a linux user and never use a file manager but I use gitk all the time. :-)
I check every commit there to see that I've not left debug printouts, that commit message
is ok and so on, where to do merges from and/or rebase's and which commit touched which files.
You should use it more, it is really useful.
Dialyzer "is a static analysis tool that identifies software discrepancies, such as definite type errors, code that has become dead or unreachable because of programming error, and unnecessary tests, in single Erlang modules or entire (sets of) applications." (ref.
documentation)
1) After installing new erlang or running dialyzer the first time (by considering you are using the MSYS shell):
$ rm ~/.dialyzer_plt (or whatever the file is)
$ dialyzer --build_plt --apps erts kernel stdlib wx
2) Start wings (and erlang) from Erlang shell:
1> dialyze().
OBS: Have lot of patience and memory
