[9fans] request: native graphics on OS X

[9fans] request: native graphics on OS X

[Russ Cox]

If there is someone out there who has a Mac and some spare cycles,
please Please PLEASE look into writing a Carbon-based (not X11-based)
back end for drawterm or for Plan 9 ports (if you do one, I'll do the other!).

The only hard part is finding out how to interface with Carbon from C.
The demands that Plan 9 graphics make on the underlying system
are really very minimal, the X implementation notwithstanding.
As a simple example take a look at the win32 code in drawterm,
which is only 646 lines to deal with mouse, keyboard, and graphics window.
http://cvs.pdos.csail.mit.edu/cvs/drawterm/gui-win32/screen.c?annotate=1.4
Ron's mention of a /dev/fb-based draw setup is similar proof.

If you know of good documentation but don't have time, please post any
links to docs that might help someone else.

Thanks.
Russ

I'm assuming I just need to reimplement src/cmd/devdraw?

I didn't mean to guilt anyone into action.
Working on either src/cmd/devdraw or a new
drawterm/gui-mac directory would be fine.

You should look at the drawterm/gui-win32
directory either way, since it shows how
much simpler the hook code can be if you're
not trying to make remote network graphics
work well.

It's not a deep guilt.  I can stand to throw a little back to the  
community.

And wow, that is miles simpler.  I'll see if I can't get it going.

> Any update here?

Paul got the native OS X graphics code working a few weeks ago.
I have just checked it into the CVS repository.  The tarball at
http://swtch.com/drawterm/ is up to date.

If before you used make 'CONF=osx' to get the OS X/X11 build,
you should now use make 'CONF=osx-x11'.  Using plain make 'CONF=osx'
will now build the native Carbon version.

There are still some things that could be done in the graphics code.
In particular, it would be nice if the keyboard modifiers that X11
uses to get alternate mouse buttons worked here too -- otherwise
on laptops you have a one-button drawterm.

The changes I have just pushed out are untested by me (I tested
an earlier version of them) and may not even compile (I am not at
a Mac right now).  Mail me and Paul if you have any problems.

I might add that I witnessed a crash bug today (first in several days
of use); of course I didn't have OS X set to generate a core dump.  Grr.
I'll happily accept core dumps :-)

There's already a bug fix in (Thanks Charles), where I missed the
qlock around flushmemscreen - you might want to wait until it shows
up in cvs before distributing an executable.

because of CGImageCreateWithImageInRect it looks like it's 10.4 only
which might be why it's not working on the imac?

Hmm I got a binary from andrey and when I run it on my iMac it just
hangs when trying to connect to mordor.  Can't enter anything to
authenticate.

Actually that happens if I just launch it in general it seems too.
This wasn't the case on my macbook though.... odd.

Ok this patch seems to get me 100% compiled :-)  I had to replace
__Darwin__ with __APPLE__ because gcc doesn't set __Darwin__ anymore.

And even after that, it behaves just as Andrey's binary did, it just
gives me the "spinny beachball of doom" on Mac OS X that causes me to
force quit.

I suppose I'll have to break out the debug tools sometime.

new binaries on 9grid fix a problem with the cat-tongued ibm mouse we

russ has the diff so cvs is probably updated already.
