Hi Thomas,

There are two questions:

1. Should a general solution to language specific indentation go in core,
most definitely yes, when we know what that is !!!

So far such a solution has not been found, Colomban's regex prototype was
closest but still had a high proportion of incorrect results leading to the
conclusion that the approach was not capable enough.
Implementing a bad approach in core and then having to try to fix/expand or
replace it is just a waste of time.

So as I said trying out indentation schemes in plugins makes it easier to
replace them (but the user can always still use the old one if they like it
better, they can't do that with in-core code that has been removed).  There
is a PR that demonstrates that plugins can be autoloaded by filetypes, so
each plugin only needs to do one language, making them simpler and easier
to get right.

Then it will be possible to identify commonality that is suitable for
implementing in core.

2. Should this particular function Thrawn is offering be in core?  Since it
is limited to one situation in one language (or group of {} languages) and
he wants to implement it in Lua, no.

Now that you mention it, there is probably no reason why we could not
default enable some of the plugins shipped with geany, its just having the
settings in the default config file.  And possibly some more plugins could
move to core (+1 for Enrico's Addons TODO for example :)

Note that it is probable that Geany core could provide some more support
for plugin indentation, but as yet nobody is sure what that consists of.
