Coding guide lines / formatter

[tobias-hammerschmidt]

It would be nice if some coding guide lines and some formatter settings could be made part of the pellet repository. At least the common IDEs like eclipse or intellij idea should be supported. Its already fun to work on the pellet codeline with lots of mixed spaces and tabs (lets not get into this discussion). Automatic formatting of source code which is often enabled in IDEs also doesn't improve the situation when comparing changes in pull requests.
