An alpm_find_satisifier equivilent is what I want too, thing is once you get the package names from that alpm_find_satisifier equivelent what are you going to do with thoes names? Probably call "info" on all of them. So why not skip that step and just have info support it.

Yes point b is what I was thinking. info("foo") would return "foo" because it matches by name, and it would also return "foo-git" because it provides "foo". Maybe it would be &type=info&by[]=provides&by[]=name rather than just "info". Point being you still get the same hunk of json that info gets you.

Would your type=provides return just package names or the same stuff info does? If its the latter it's the same as what I want but under a different name.
