design encoding scheme for module and class names

[boegel]

We need an encoding scheme to handle problems with names of software packages that would yield identifical module and/or class names via the current scheme (lowercase module names, camel-case class names).

Clashes would occur for e.g. 'R' / 'r', 'LAPACK' / 'LaPack' / 'lapack'.

Problems would also occur for e.g. '7zip' (class names can't start with a number), '_' or '-' or 'c++' or '|' .

Hi there,

this guy seems to be doing the same thing to escape funny symbols like the one we discussed:

Hi there,

I think the patch for this issue is ready by now as seen over here:
https://github.com/fgeorgatos/easybuild/tree/86_new_encoding_scheme

when I do the testing though it breaks as follows:

fgeorgatos@gaia-1:~/easybuild$ time eb -k Python-3.2.3-goalf-1.1.0-no-OFED.eb -ld -f

documentation draft: https://github.com/fgeorgatos/easybuild.experimental/wiki/Encode-class-names

[boegel]

documentation added to main EasyBuild wiki

@fgeorgatos: For subsequent documentation, please create it on your EasyBuild repository (as opposed to on a different repo, easybuild.experimental in this case).

That makes it easier for us to pull in the documentation, and push it to the main repo.

Code has been merged in develop, and documentation is taken care of, so closing this issue.
