[03:07:58] <seb_kuzminsky> yeah, if it doesn't use the parport it should probably move, but i think you know better than i where it fits best

[16:00:38] <seb_kuzminsky> zultron: if the build system detects a xenomai kernel, it should build both the xenomai and xenomai-kernel flavors, right?
[16:17:33] <zultron> Hi seb_kuzminsky, I hope so. :)
[16:18:05] <zultron> The intended behavior would be if the xenomai-devel pkg is present, build xenomai; if that and a xenomai kernel headers pkg are present, build xenomai-kernel.
[16:18:34] <zultron> (And if multiple xenomai kernel headers pkgs are present, build xeno-kernel modules for each)

[17:14:46] <cradek> the idea, no problem - but can you just use inifile.find(...)? using findall and then discarding all but the first seems weird unless I am missing something
[17:15:04] <cradek> also, is the second hunk unrelated?
[17:15:50] -!- Jeebiss has quit [Ping timeout: 245 seconds]
[17:16:19] -!- rob_h has quit [Ping timeout: 260 seconds]
[17:17:21] <cradek> is the second hunk a bugfix? you moved the last line inside the loop, and that seems wrong at first glance

[17:41:21] <dgarr> the second hunk was just editiig tab damage, i've restored that and fixed up findall in the patch. touchy.py seems to have a mixed set of tabs and indents ?
[17:42:33] <cradek> cool, can I see this version?
[17:42:38] <dgarr> using an alternate glade file for gui small enough to fit 640x480: http://www.panix.com/~dgarrett/stuff/touchy_small/
[17:42:59] <cradek> yeah mixed tabs and indents are a scourge but fixing them is worse
[17:43:00] <dgarr> patch is in the same place: http://www.panix.com/~dgarrett/stuff/0001-touchy-allow-alternate-gladefile.patch
[17:43:36] <cradek> I am surprised to learn that it won't work on 640x480 as-is

[17:51:02] <cradek> I think you are opening the inifile twice and perhaps leaking at least a fd, maybe whole python objects (I'm not sure about the scoping rules)? I think the fix would be to move the inifile opening from line 176 above where you need it to get the gladefile, then use self.ini.find
[17:51:23] -!- ktchk [ktchk!~eddie6929@n219073006195.netvigator.com] has joined #linuxcnc-devel
[17:52:31] <cradek> that line 176 block is in a weird place
[17:52:59] <cradek> ugh, it gets opened again later for reading UNITS
[17:53:31] <dgarr> yes it seemed it already opened more than once
[17:54:18] <cradek> could you fix that in commit #1 (also moving it above where you need it) and then add your glade stuff in commit #2?
[17:55:30] <cradek> postgui handling also does it
[17:55:43] <cradek> I can fix this (later today) if you don't want to

[19:06:03] <dgarr> cradek: mbox revised, i've just used wmctrl or wminfo to measure size and when small enough tested by modifying display (xubuntu and xfce)
[19:10:09] <cradek> dgarr: this looks excellent now, thanks for cleaning it up
[19:10:43] <cradek> I see another problem (assumptions about argv[2] in postgui loading) but it's getting really far from the changes you want to make, and not a dependency at all
[19:11:49] <cradek> dgarr: I'm curious - what changes do you make to the glade to let it get smaller?
[19:13:30] <dgarr> quite a bit, this patch follows the two in the mbox (work in progress): http://www.panix.com/~dgarrett/stuff/wip.patch
[19:14:10] <dgarr> bbl, please post if you find vanilla glade file can show all at 640x480
[19:14:25] <cradek> the height of the status screen is what's keeping me from sizing smaller
[19:14:36] <cradek> um, it shows all 55 pockets, that can't be right
[19:14:48] <cradek> they all have T00 in them, haha
[19:15:18] <cradek> I'm at 614x503 without changing anything except fonts with the font chooser

[19:20:08] <cradek> creating a tool table lets me get to 640x480 easily: http://timeguy.com/cradek-files/emc/touchy-640x480.png
[19:20:29] <cradek> without even resorting to tiny/ugly fonts
[19:20:41] <cradek> I wonder why it's different for you

[20:44:55] <andypugh> Is it bad form to use the result of a comparision in a calculation?
[20:45:14] <andypugh> ie, use "true" and "false" as actual numbers.
[20:46:55] <seb_kuzminsky> yes, i think so
[20:47:10] <seb_kuzminsky> booleans are not integers, and treating them as such is confusing to my feeble brain
[20:48:00] <andypugh> So, to take a not very random example, if (a % b == (b > 1)) would be less preferred than if (a % b == (b > 1 ? 1 : 0))
[20:49:23] <seb_kuzminsky> i'd prefer "if (b == 0) { do_one_thing(); } else { do_another_thing(); }", but i understand that may not be a universal preference
[20:49:27] <andypugh> Alternatives are an extra constant, or a third clause in the if-else
[20:50:07] <seb_kuzminsky> both of the ways you wrote look foreign and too-clever for me, but then you're foreign and clever so maybe that's ok
[20:51:25] <andypugh> It's the resolver "index" code http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/hal/drivers/mesa-hostmot2/resolver.c;h=3fca0a16f6eeeea30ad90098e81f5e225a0b7b96;hb=9a4a626bcee4f65071b98cc448e83fccd68356a1#l325

[20:52:09] <andypugh> It's already an 8-line "if"
[20:53:31] <seb_kuzminsky> i dont envy you the task of finding the clearest way to express that... expression

[20:55:17] <andypugh> I am not proud of that code, and it took a lot of fiddling to get it nearly right. Except in doing so I got it really wrong.
[20:56:25] <andypugh> (Because N % 1 == 1 is unlikely...)

[21:08:31] <andypugh> It's a bit if a pain to get this compiled and running on a machine with an actual resolver. But I guess I have no real choice.

[21:10:09] <andypugh> I think the resolver machine is running mah's "Jog while paused" trial, and it might have compiled it from my shared git which is currently on a different branch. Oh joy :-)
