|
||||
|
||||
After a very long time I decided to give a rewrite of [[software/gpm]]
|
||||
a try.
|
||||
|
||||
## Motivation
|
||||
|
||||
The
|
||||
[recent discussion on the mailing list](http://lists.linux.it/pipermail/gpm/2010-May/thread.html)
|
||||
reminded me of one thing, since I overtook gpm maintenance:
|
||||
|
||||
* There are a lot of problems with gpm
|
||||
|
||||
Don't understand me wrong, gpm is a great software, knows how to handle
|
||||
a lot of mice and has many interesting programming techniques inside.
|
||||
|
||||
To extend gpm or to debug it, is pretty hard, as the code is not easy
|
||||
to read nor to understand (though fun if you do).
|
||||
|
||||
Some time ago I asked around in the world of BSDs, in the Linux kernel,
|
||||
what their preferred way would be to handle mice.
|
||||
|
||||
As there have been almost no responses, it seems everybody does his
|
||||
own thing. I was also considering whether merging gpm into some
|
||||
"general input library" makes sense, but at the end of the day:
|
||||
I only care about mice.
|
||||
|
||||
## Current situation
|
||||
|
||||
So yesterday evening I began to hack a new version of gpm, [[software/gpm2]],
|
||||
which can show you some ps/2 mouse movements as of today.
|
||||
|
||||
The concepts of gpm2 are quite different to those of gpm, especially that
|
||||
gpm2 itself **cannot**
|
||||
|
||||
* decode mice protocols
|
||||
* draw a pointer
|
||||
|
||||
Instead the idea of gpm2 is to have external programs do that and make
|
||||
gpm2d just an interface to access the various mice.
|
||||
|
||||
The "special case" of drawing a pointer can be realised by writing a
|
||||
client that does only that particular job.
|
||||
|
||||
## The future
|
||||
|
||||
I am not sure whether to invest a lot of work into gpm2 or not.
|
||||
On the one hand I would be pretty happy to have a clean, portable
|
||||
mouse handling daemon on the other hand I am not sure whether there
|
||||
is really a need for it.
|
||||
|
||||
In case you think there's a need for it, I would like you to drop me
|
||||
a mail to **nico-gpm2 () schottelius.org** and let me know what you
|
||||
think about the current design ideas.
|
||||
|
||||
And if you like them very much, you're invited to port / rewrite
|
||||
mouse drivers for gpm2. ;-)
