Dear all,

I would like to add a new flavor to the discussion. Lately I stumbled upon uncrustify [1], which is a command line code formatting tool for various languages. Given a text based config file it can more or less format _every_ aspect of the code (this is, I believe, not an exaggeration! It took us several hours to work through all settings). Such a config file can be crated in a graphical way using the universal indent gui [2]. What I like about these two tools is the following:
* they are available on all platforms, open source and free
* the configuration lies in a text file, which can be easily distributed
* the configuration covers every possible aspect (once agreed upon everyone can infer the settings for their editors)
* uncrustify can be integrated into most editors (if only by defining an external tool and assigning a shortcut) and version control systems

Given such a config file, users can adapt their editors to comply with the config file (or use uncrustify directly). One could even implement uncrustify as a post-commit hook to check if commited files comply with he coding standard (if wished). I do not care that much about the actual configuration but I think it would just be great to have.

If you want to play around with uncrustify I recommend getting your hands on a recent version of both uncrustify and the universal indent gui. I also append a sample config file to play with (not a suggestion for an actual configuration!). Be sure to run uncrustify with '-l CPP', since it would otherwise interpret .hh files as C code: 'uncrustify -l CPP -c sample.cfg --replace *.hh'

I do thus ask for opinions and, if there was general agreement, would be willing to create a first configuration file base on past discussions and try to moderate an agreement upon a configuration.
