Add pymt support for mtdev

[Henrik Rydberg]

Adding pymt support for mtdev would be nice.

[Mathieu Virbel (tito-bankiz)]

I already started the python binding, will be published very soon.

[Henrik Rydberg (rydberg)]

Has it been published somewhere? :-)

[Mathieu Virbel (tito-bankiz)]

It's committed : http://github.com/tito/pymt/commit/4ecfad4c046c69db1b3ef2044557f648c2187cc0

Packaging for next version is < 2 days

[Henrik Rydberg (rydberg)]

I checked it out at github. Running touchtracer seems to work fine. Great!

[Mathieu Virbel (tito-bankiz)]

Can you paste the log at startup ?
I really want to be sure that it use mtdev and not hidinput :)

It says it uses mtdev, and I put "mtdev,/dev/input/eventX"
in the config file. I doubt hidinput is capable of showing seven fingers?

hidinput read directly from kernel, and i've got a stantum screen using it with 12 touches :)
ok, thanks for testing !

[Mathieu Virbel (tito-bankiz)]

It's already done and released inside PyMT 0.5.1.
And for the pure binding, it's available here : http://github.com/tito/python-mtdev

[Duncan McGreggor (oubiwann)]

Very cool, Mathieu!

I'm wondering, though... where is the appropriate place for this? Seems like it should be in the mtdev codebase. And that, to use it, pymt could optionally (at the discretion of the user) depend upon mtdev.

Henrik, Mathieu, what are your thoughts?

[Henrik Rydberg (rydberg)]

I already fended this off strongly, on the basis that mtdev is moving towards the kernel, and having python dependencies would be very awkward. If Mathieu feels the generic python part should be someplace else, perhaps we should think about adding another package, with support tools of various kinds.

[Duncan McGreggor (oubiwann)]

Okay, cool. Good to know about mtdev heading toward the kernel.

In that case, I do suggest we create a new project and package for python-mtdev. We can get help from Chase on pacakging, and get it ready for Natty. This way, folks who want to use it for their own projects can just depend upon it directly.

[Duncan McGreggor (oubiwann)]

Mathieu,

Done: https://launchpad.net/hci/python-mtdev

I've added you as an admin of the team. We can open some tickets in that project for getting stuff moved over and packaged up for Natty.
