Re: Automatic pretty-print

This is not my case. I don't want to impose my programming style because I
think is better. All programmers in the group have accepted this style simply
because they don't want to see another piece of code that is not formatted as
they will expect only because other person wrote it.

We all are agree with this style but I think is to painful to impose the
programmers to do the pretty-print in each commit. I think for me this tool
(Subversion) is very good but it's missing some functionality. The
restriction for the pre-commit hooks not to modify the data is too strict. I
think for future releases, subversion could accept the modifications in the
pre-commit hooks, syncronize the commiter with these changes and insert the
new revision in the database.

Maybe this reason for pretty-printing is too fool to consider but I can
imagine a situation where the repository must be a 'canonical copy' of the
data summitted. I cannot think why all commiters must execute the canonical
transformation and not doing in the server-side if it's much simpler.


PS. I was thinking that maybe it was possible to do so but what you are
suggesting me that this is not possible. :(
