Thanks to Glynn's expert help, I added a G_find_etc() function to
libgis, and a companion g.findetc command.
These are used to locate support files for C and script modules that
may be in a directory not inside the GRASS installation ($GISBASE/
etc). They are intended for use by addon modules and scripts that
are installed externally to the GRASS installation ($GISBASE). The
search paths are specified in the env var GRASS_ADDON_ETC. If not
found in those paths (or none are specified), it tries $GISBASE/etc.
To use, instead of hardwiring the etc path to $GISBASE:
sprintf(path, "%s/etc/somefile", G_gisbase());
search for it with:
path = G_find_etc("somefile");
and make sure to test for null = it wasn't found.
For scripts, use something like:
Works to find both files and folders, and subfolders. The Mac OS X
app startup has been updated to add the default global and user addon
etc folders to GRASS_ADDON_ETC.
This is a followup to my message from March:
