Yes, I also store environment variables in the quirks file - it's what I
was alluding to as "possible further use of a quirks file" in the
original email but didn't elaborate on as it was already so long.
In the case where python3 is optional but not autodetected, thus
requiring a "PYTHON3=yes" in the environment, the quirks file entry I
use is something like:
QK_REQUIRES = python3
QK_ENVOPTS = "PYTHON3=yes"
HooRex itself ignores the QK_ENVOPTS line. However my package building
software recognises that line and exports PYTHON3=yes when starting the
The quirks file is in .INI file format. It's easily parsed in Python
(import ConfigParser), which suits HooRex. It's also easily parsed in
bash (which suits my package building software) by including
although I had to rename cfg_parser() to cfg.parser() due to some not
clearly remembered issue to do with allowable function names in bash.
