Filename extension is a "suffix to the name of a computer file, designed to show its format" (-- wikipedia). General format of ebuilds is bash. Putting version of bash scripts inside filename extension just breaks common convention people got accustomed to.

You don't need to parse full bash script. You just need to get EAPI="something" string from there. If you wish to implement new ebuild format, e.g. ebuilds in xml, in such a case you'll change extension on .xebuild or whatever suits better. > Another cache won't solve anything since there's no way to generate > that cache to begin with -- and a second level of cache would slow > things down, not speed them up. I told about caching just to avoid "it's slow to get EAPI from ebuild" argument. > Because all the alternatives are worse, and none of the objections to > the extension have been technical in nature.

If by technical objection you mean 'explanation why technically it's impossible or bad to implement .eapi extensions' I agree with you. It is possible to code it and it will work. But ... again. Statement is: Filename extension is a "suffix to the name of a computer file, designed to show its format". General format of ebuilds is bash. Putting version of bash scripts inside filename extension just breaks common convention people got accustomed to. Although this is not a technical objection it is not unimportant. Even color is important if your are talking about things people will see/use on daily basis. I doubt you'll paint your room in violet only because you can easy get this paint right now. That said, technically there are other solutions for this problem, e.g. 1) it is possible to read one line of defined format from any file 2) it is possible to make eapi inside ebuild name (foo-1.0-eapi2.ebuild), but not as extension. Any solution, even breaking compatibility solution, we could already start using if we had forgotten about GLEP 55 long time ago... Putting GLEP 55 infinite number of times on council agenda makes me feel that this issue has something common with perpetuum mobile. At least I'd like similar resolution from our council as the Royal Academy of Sciences in Paris did in 1775. It's hard to tell anything new about GLEP 55 but people still don't like it, so, council, please, ban it forever and let something else arise. -- Peter.
