It might be just a typo on your part, but it is the biggest A*P*I number
you get from the table that you plug into the version check. You don't do
anything with the ABI number, its automatic.
Or to be more realistic, plug in the API number of the geany you are
developing your plugin against. If you are using a function that is too new
for the Geany you are using you will get a compilation error. So simply use
the oldest version of Geany you want the plugin to work for and sit back
and let the compiler take the strain :)
If you develop with a new version of Geany, then only when you are *sure*
your plugin is finished should you consider looking for the oldest version
of API that will work, therefore defining the oldest version of Geany that
will work. But due to the unfortunate changes of ABI that have happened
every few versions, people will have to compile your plugin themselves to
use older Geany versions, so your audience is narrowed significantly (those
who use an older Geany but are willing to compile plugins). It is not
possible to use a precompiled plugin with a version of Geany that has a
different ABI, even if the API is ok.

Actually I wanted to know how to add them to the g-p build system, rather
than just plugins in general, since I havn't done anything g-p before :)
Since various people claim its just copying the examples in the docs I'll
see tomorrow :)
But thanks for the feedback that it isn't clear how best to use the API/ABI
versions, thats the sort of info the experts need if they are to be able to
improve the docs.
