About calling the release “Moore”

Following the tradition to pay tribute to old heroes who have passed away this release is named after Gary Moore. I used to listen to Thin Lizzy and from there I discovered Moore. Somewhere in a box somewhere I have a shaped picture 12″ vinyl of Shapes of things. This song is written by Yardbirds member so I discovered them through Moore ….

A proposed name for this release was “frownland” after the super amazing song Frownland on the album “Trout mask replica”, but …. “Captain beefheart” is the name.

FSCONS:
The Free Society Conference and Nordic Summit is a meeting place for social change. It’s a conference for and by the people who work to change our future.

Call for testers: Xnee 3.06.96 (in prep for 3.07)

 Support for X Input* has been added to GNU Xnee. Tests have been performed on:
     Debian Lenny
     Ubuntu 10.04
     Mameo , N900
and things (finally) seems to be working.

Building
---------------
Download:
    http://alpha.gnu.org/gnu/xnee/xnee-3.06.96.tar.gz

... unpack and build:
tar zxvf /home/hesa/gnu/xnee/xnee-3.06.96.tar.gz
cd xnee-3.06.96/
./configure --disable-gui --disable-gnome-applet --enable-xinput2 && make

Before releasing 3.07 it would be great to have some more tests done on other environments. If you can, here's some test cases:

Preparation:
-----------------------------
Execute:
    ./cnee/src/cnee --record --mouse --keyboard -o test-xi.xns -sk q

Move mouse, press and release some keys, ... stop recording by pressing q

Test case 1 "XI Replay":
-----------------------------
    ./cnee/src/cnee --replay -f test-xi.xns

Test case 2 "Core Replay":
-----------------------------
    ./cnee/src/cnee --replay -f test-xi.xns  --force-core-replay

Send feedback to http://lists.gnu.org/mailman/listinfo/bug-xnee  (or to me and I'll compile and anonymize your report and forward it to the list)

*) Multi-touch, multiple input devices ....

xswine: new program for the GNU Xnee suite

I been writing a small program, xswine, that can take a recorded GNU Xnee session file and replay that to swinput . Swinput had its share of changes and a new swinput release will see the light of day any day. The difference betwen replaying using swinput compared to replaying using Xnee itself is that swinput fakes the device events from the kernel and Xnee fakes at X11 level using XTest.

There’s a some questions that need to be solved before a proper xswine release, such as:

• how to map the device id as recorded from X Input Extension to the “correct” input device as presented by swinput
• timing – what do we do when we drift away from the start time, but want to keep the recorded diff between events

Currently there’s not much of the recorded X11 events that can be replayed. Here’s the current list:

• X11 motion event – no
• X11 button event – no
• X11 key event – no
• X Input device motion event – yes!!!
  
• X Input device button event – no
• X Input device key event – no

This means xswine can replay (using the kernel) recorded Multi-touch events!

But if that’s all xswine can do do, why do I bother writing a blog entry. Two reasons:

1. nobody reads my blog…so nobody will complain about this blog post
2. I want to “claim” the name xswine

So, what does xswine mean?

X – is for Xnee

swin – is for Swinput

e – dear reader of this blog (just claimed I had zero readers!), help me out … what should e stand for?

If you compile GNU Xnee and swinput (and install) from CVS HEAD you should be able to do:

sudo modprobe swmouse devs=4 && sudo chmod a+rwx /dev/swmouse*

./cnee/src/cnee --record --mouse -o whoa-mule.xns

cat whoa-mule.xns | ./xswine/xswine

Cnee records (partly) on N900/maemo

Some progress have been made on the work to make cnee (part of GNU Xnee) work on the N900. Earlier I reported that replaying works.

Now recording of mouse clicks (press, release) and key press and release works. But, MotionEvent cannot be recorded…. Feels like diving into the X server of N900 is the thing to do.But before that I shall report back to this: http://lists.maemo.org/pipermail/maemo-developers/2010-July/027097.html

If you want to test the last cnee for maemo, here’s a binary built from CVS HEAD 2010-09-12 23.50 (ish):
