EAPI checking in eclasses

12-31-2007, 01:34 PM

Is it legal for an eclass to check the EAPI version (presumably by using the EAPI
variable) and perform some dependent behavior based on what it sees? I don't see
any eclasses using EAPI for anything, so I'm curious.

Yes, so long as that dependent behaviour isn't intended to indicate an
error.

You can't treat EAPI as an integer, though, which the commit to the qt
eclass did. You might want to do a case statement instead for string
matches.
