I agree that it is not good to encourage using of it yet. The bare
minimum of functionality is the undo/redo. Or at least backing up the
project somehow before.

I think encouraging people to use this is very dangerous. It is tied so
much into our internal APIs at the moment. The more people who use it,
the more everybody is going to scream every single time we change
anything. We have so much poorly structured code that needs to be
rewritten - I'm sure a lot of it *will* be when it comes time to remove
the legacy canvas. If we end up with this many users of the scripting
API, we will never be able to touch anything again without breaking
everything.
Wayne, JP: I'm making an appeal to you now to be conservative with
what you accept for use with the scripting API. This would be a very bad
point to lock ourselves into having to stabilize it as is. I do not
think we should be doing this until an interposing layer with a
formalized, stable API can be created.

Hi,
Just from my point of view:
We use some python plugin currently and it's not really easy to open
each time python console (and remember plugins name, call mode...).
I'm agree with you: During devs of scripts it's crashing and my devs
have to find the rigth way to process.
But this kind of feature can increase number of users/devs of this kind
of scripts and raise crash case easily.

Frankly I don't think we should be encouraging users to use the Python
API until it is significantly improved. The issues JP raises make the
API completely unsuitable for plugin use. It's opaque and no users have
any idea how to write robust Python plugins given the current state of
the API.

This is a good work.
Thanks Jean-Samuel.
However, before merging we have to take care of issues which can
easily crash Pcbnew:
Because a python script can modify the board outside the control of
pcbnew edit functions, I am
thinking problems will arise with undo/redo lists (invalid
pointers), ratsnest data and certainly a
few other things.
Especially for scripts which add or delete items, or change
connectivity.
Of course, undo/redo lists are alway incorrect after running such
scripts.
This is already a known issue for scripts that are run from the
Pcbnew python console.
