Re: [LMMS-devel] Piano roll

[Paul G. <dr...@gm...>]

Joshua,

The Cusis them is actually something I started to implement when Mike
created it a few years ago.  This is when I discovered that the theme
support needs an overhaul.

Emilio,

Yes, loading from something such as an ini file will work, although I
think a format such as CSS is more appropriate.  I don't have anything
special to say about the code, but if you ask then I can add my
response to the wiki:
http://lmms.sourceforge.net/wiki/index.php/Developer_Documentation

Regarding pulling changes, we are using git, just not on github.  So
everything you know about git still applies:
http://lmms.sourceforge.net/wiki/index.php/Accessing_Git_repository

What I would do, if I were you and you want to maintain a fork on
github, is something like this:
Create a repository on github
git clone --origin upstream git://lmms.git.sourceforge.net/gitroot/lmms/lmms
cd lmms
git remote add -t master origin <path-to-github-repo>
git push --force origin

This will clone all the LMMS repo onto your computer, the official
repo is named "upstream".  Then you add a remote repo for your newly
created github repository named "origin".  Then you push all of the
commits to your github repo.  For maintenance, you can do something
like:

git push origin # Push changes to origin whenever you like
git pulll upstream # Occasionally merge in changes from upstream

I hope this helps.
