This cleans up the way gnap_* scripts get their information. Since i
mostly worked on gnap_make this is optimized for gnap_make and the other
scripts are only changed in the same way. In gnap_make we have the
following sources of configuration:
- The command line
- common.conf
- catalyst.conf
- the environment
Until now, catalyst.conf was used for... i don't know, it was sourced
but not really used, i think. common.conf was used for all the arch
specific stuff, that has to be passed to catalyst. The command line was
used for most of the configuration options, including the location of
common.conf and catalyst.conf.
The new behavior is the following:
gnap_make and gnap_shared specify default values for all the GNAP_
variables (sometimes undef is default). This can be overwritten by
environment variables (export GNAP_LIBDIR=/home/test/foo/bar for
specifying the place of all the gnap files for testing new
configurations, export GNAP_CATALYST_BIN="echo catalyst" for only
getting the configurations created by gnap_make and not building the
stuff come to mind), next the spec location is read from command line if
available and common.conf is sourced, the catalyst.conf info is read
from the command line if available and the file is sourced, the rest of
the command line is read and sets/overwrites whatever is given there.
With this you can:
- add GNAP_ options to catalyst.conf (DON'T DO THAT)
- add GNAP_ options to common.conf (shorter command line, nice)
- add GNAP_ options to the environment (GNAP_LIBDIR since we only use
tha lates testing stuff located in /home/somewhere, whatever you want)
- have new problems because you don't know why a special option is set.
Well, if you are advanced enough to make such a mess, you are advanced
enough for cat, grep, export -p and set -x to debug that.
Before i gorget it: I also did some more cleanup here. I was too lazy to
apply it to all the previous branches that it would be in the -cleanup
patch, i hope you can live with that.
Enjoy,
Philipp
