To me this seems to be much better than the current state and would
solve all the problems I have with the current settings (like the mess
with the project filetype configuration). As we talked about it in our
programming language thread - one has to make compromises during the
design - this solution is very slightly less flexible but much easier
to understand how it works, which is more important IMO.

No, my point wasn't that they shouldn't be per filetype - my point was
that the dialog doesn't say that! So at least there should be
something like "execute commands for C files". In addition, the order
of the groups in the dialog suggests that they are global - first
group is per filetype, the second group is global and you expect that
the third group is global too because it follows the global options
and the title doesn't tell you.

Ideally, I would like to see:
* Non-filetype commands first
* Filetype commands + executes second - they would have to be somehow
visually grouped so you would know they are per-filetype. I think the
combobox with the currently selected language would contribute to
making it clear these are dynamic.

I'll read it once it's online on geany's web page. But unless I
overlook something, it's not there right now. But if there is such an
option, great, no extra implementation needed.

Nope, I avoid them (for multithreaded server applications anything
like global variable is evil). For gproject I use only static
variables per-file which are a sort of alternative to member variables
in classes.

Not quite sure what you mean here.

But you can still use the global commands to run python (whatever
version you want).

No, because you don't have any indication that a command is overridden
in project. So even you know you saw there was python2 in the project
properties last week and you know you haven't changed the project, you
will be running python3 because meanwhile you changed your global
properties. This is just totally wrong. My suggestion was to drop the
per-filetype commands from the project, but you can use whatever other
reasonable way. It just has to be fixed some way.

See above, this is confusing. One more idea I have is to have all the
project filetype commands initially blank - meaning they use the
global commands. There would be a "copy from global commands" button
that fills the commands by those used in the global options (to help
you initially fill the commands). Once the filetype commands aren't
blank in the project, it means the commands override the global
commands. With this you'll know when some commands are overridden or
use the global settings.

Don't take the list of required members of the settings structure I
mentioned too seriously - others are reasonable for all projects too
(but some are not and these should be private). Regarding the rest,
see my comment below.

I think you misunderstand the message behind my comments (and possibly
I wasn't expressing myself clearly).

The only two things I want is:
* to have simple and understandable settings dialogs with clear semantics
* every project management plugin to have the same rights as the default one

The rest were just the means of how to achieve that. I'm not strictly
against per-project filetype commands; what I want to say is that IMO
the additional extra flexibility doesn't justify the confusingness.
But see see what I suggest above as the solution that preserves
per-project filetype commands. Regarding project management plugin, I
don't want to take over all the functionality of the current project -
some of its features interfere with the features of my plugin. That's
why I want to to have one "project superclass" implementing the things
common to all projects and let the concrete implementations do the
things their (possibly different) way.

Was not necessary to climb up :-).
