Ok - I've added the current API to the wiki . I did not manage to
include all of the needs of porthole, as I don't know what some of the
calls do, and whether they are really needed ;).
Please see the attached file for the comments.
@dol-sen: Would be great if you could scan through the list and see,
which ones are really needed. Because portage calls inside functions
that are then moved into catapult don't need to have an equivalent in
the API (at least in most cases). - And for the vast majority I was just
clueless ^^. (and too lazy to lookup portage code).
There are certain issues with the current API:
1.) Add some more stuff needed by other frontends.
2.) Perhaps merge the Package and the System object as they both just
3.) Merge package.is_in_overlay() and package.get_overlay_path()
4.) Get rid of the different get_*_settings functions and add special
ones: get_homepage, get_depend(which), get_arch, ...
5.) Currently there are two functions returning use flags which were set
at installation time of a package:
- get_use_flags(): Returning ALL set useflags
- get_installed_use_flags(): Return only the set useflags which are
also in IUSE.
This should perhaps be merged into one function with an attribute
"only_iuse" or similar.
Some comments are appreciated ;)
