Putting words in Steven's mouth, but I would say a major advantage is it
doesn't need Lua or Python.

You will have to add those to the lua interface, they are available in the
geany plugin interface so it shouldn't be too hard.  Just a little C
programming.  And documenting!!!!

Well the Geanypy interface tries to wrap the whole Geany plugin interface,
Geany lua has its own very restricted interface, simple, but limited.

Well, if you have to install all of Python, yeah, but then many (most)
systems include it now anyway.  And the -dev packages are only needed to
compile geanypy, using the packages noted above shouldn't need them.

But still with no maintainer you are running the risk of the plugin being
removed and all your work being useless.  Especially if you are going to
add to Geanylua itself (eg GUI access), find a maintainer, or become it
yourself.  (you may need to do that anyway to add stuff, with no maintainer
there is no committer, unless you impose on someone else)

Methinks he exagerateth for effect ;)

Geanypy could be made part of geany-plugins, there are some issues to
solve, but it works well enough for many uses that they don't need to be
solved first.  But Matthew is a perfectionist.

I'm sure help would be given on the build system issues if geanypy was to
be included in g-p (but don't look at me, I'm autotools ignorant :).

How do you handle modality?
