I'm have done by now 90% of the application and I'm busy with minor issues like code style checking. I download and installed the eclipse chekStyle plugin. When activating it I saw a huge (really huge ) amount of messages like this:
Depends on assessor. I'm currently working on project (C/C++) with about 70 developers, some of them use tabs some spaces,.. some of them think tab is equivalent to 2 spaces/4 spaces/8 spaces and sometimes it is annoying to read/merge such files. (But I guess it is less annoying then "^M")
It is not a problem to convert tabs to spaces in eclipse, but if you want use tabs then make sure it is consistent across all your files.
