I think the general policy is to export stuff on demand as plugins need
it. Seeing as you wrote the API in question, I'm assuming you know best
the stuff you will need, so I don't personally see much problem
preemptively exposing that stuff.
From you're previous email you mentioned the stuff checked with [x] below:
[ ] spawn_get_program_name()
[ ] spawn_check_command()
[ ] spawn_async_with_pipes()
[ ] spawn_async()
[ ] spawn_get_exit_status()
[ ] spawn_sync()
Is that sufficient, or is there other stuff? I will remove the /** from
anything that is not expected to be needed, if nobody objects.
About the WIF* macros, those (at present) are not "officially" part of
the plugin API as they have no Doxygen comments, though they will still
be visible to plugins since they're macros and bypass the linker trick
we use to hide functions. I think it would be best to add documentation
to those (and possible define them into the "GEANY_" 'namespace'?), at
the very least to ensure nobody accidentally moves or hides them. Just
the other day I tried to move them into spawn.c thinking they were there
on accident, but then I left them because another .c file uses them so
they need to be in a (not necessarily public) header.

Well you know my opinion :) I think everyone pretty much agrees we
shouldn't expose stuff unrelated to the plugin API, and I think we all
also agree it's stupid for plugins to have to copy&paste code that
exists already or else use an inferior version. I also think everyone
agrees that a separate utility library would be a good idea. The problem
I have is that once this API makes it into the next release, it's
"forever" stuck inside Geany and we'll have to keep it indefinitely,
regardless if something possibly better like GProcess comes available
to us, and we don't even use it internally anymore.
: At least until we establish a policy around what belongs in the
plugin API or not.
: I have no idea if it's better, just an example.
