The PMS says in section 3.1 about category names: A category name may contain any of the characters [A-Za-z0-9+_.-]. It must not begin with a hyphen, a dot or a plus sign. and about package names: A package name may contain any of the characters [A-Za-z0-9+_-]. It must not begin with a hyphen or a plus sign, and must not end in a hyphen followed by anything matching the version syntax described in section 3.2. Portage allows the plus sign, though. In pym/portage/versions.py: _cat = r'[\w+][\w+.-]*' _pkg = { "dots_disallowed_in_PN": r'[\w+][\w+-]*?', "dots_allowed_in_PN": r'[\w+][\w+.-]*?', }
Same for SLOT, the spec forbids that it starts with a plus sign. _slot = r'([\w+][\w+.-]*)'
I'm not really convinced about this. Repoman warning about invalid package name, sure. But as long as portage itself can handle such a name, I don't think we should prohibit users from using it locally.

Otherwise, I'd suggest that we go for the simple solution, namely fixing the regexps in versions.py.
