[02:26:59] <jmkasunich> awallin, just who I was looking for
[02:27:28] <jmkasunich> although perhaps jepler could help too
[02:27:51] <jmkasunich> I'm trying to make a fairly minor mod to pyvcp, need a bit of help with pycomp
[02:28:36] <jmkasunich> or maybe its just python that I need help with
[02:28:43] <jmkasunich> this code snippet from pyvcp:
[02:28:56] <jmkasunich> c_halpin=halpin+"."+str(c)
[02:28:56] <jmkasunich> pycomp.newpin(c_halpin, HAL_BIT, HAL_OUT)
[02:28:56] <jmkasunich> self.halpins.append(c_halpin)
[02:29:26] <jmkasunich> after the first line, c_halpin is a string
[02:29:34] <jmkasunich> then pycomp.newpin is called
[02:29:51] <jmkasunich> it seems to me that afterwards, c_halpin is a pin, rather than a string
[02:37:58] <micges> jmkasunich: why? there is no code in this function after that part of code
[02:38:17] <jmkasunich> I'm trying to add code that creates an additional pin
[02:38:30] -!-
skunkKandT has quit [Remote host closed the connection]
[02:38:31] <jmkasunich> my python is very rusty, and was never that good to start with
[02:38:46] <jmkasunich> so I'm looking at the existing code, figuring out what it does, and copying it
[02:39:14] <micges> pyvcp code is somewhat tricky
[02:39:34] <micges> tell me what you want to do
[02:40:00] <jmkasunich> radiobutton exports one pin per button item, and turns that pin on when that item is selected
[02:40:23] <jmkasunich> I want to add one more pin, called <same-name-as-others>.index
[02:40:35] <jmkasunich> and set it to an integer that says which of the buttons is active
[02:40:40] <micges> ok
[02:40:46] <micges> what code brranch?
[02:41:01] <jmkasunich> I'm in master
[02:42:01] <micges> you want float or s32/u32 ?
[02:42:07] <jmkasunich> s32
[02:42:16] <jmkasunich> actually u32 makes more sense
[02:50:40] <micges> http://pastebin.com/6aKiUrNc
[02:51:26] <jmkasunich> thanks!
[02:51:45] <micges> welcome
[02:52:28] <jmkasunich> I'm gonna propose this as an improvement to be committed
[02:52:40] <jmkasunich> you should get credit (or just commit it yourself)
[02:53:01] <jmkasunich> I haven't done a commit in ages, and don't have a proper git repo set up on this machine
[02:53:17] <micges> wish that you were here more often, I had many questions about joints_axes branch
[02:53:46] <micges> I'll do this tomorrow, it's 4am here ;)
[02:54:40] <jmkasunich> ok - thanks again, and have a good sleep :)
[02:55:09] <micges> hehe not yet but thanks :)
[02:55:55] <jepler> jmkasunich: pycomp.newpin is not modifying its first argument -- it makes the string something that can be used to index the pycomp object, for statements like pycomp[c_halpin] = True
[02:56:45] <jepler> (indexing things with strings is pretty common in Python, that's one of the things that dicts (dictionaries/hash tables) do very efficiently)
[02:57:18] <jmkasunich> so pycomp doesn't "return" a pin object, it just creates one, stashes it away somewhere, and says "when you need this again, use the string" ??
[02:57:32] <jmkasunich> thats what had me confused, I was looking for it to return the object
[02:59:00] <jepler> I think it might also return a pin object nowadays, but the original way to do the assignment was pycomp[pinname] = newvalue
[02:59:25] <jmkasunich> I see
[02:59:50] <jmkasunich> and it (micges change) works fine
[02:59:58] <jepler> that's the important part
[03:00:18] <jmkasunich> I can pick one of 4 jog speeds, and get an integer
[03:00:29] <jmkasunich> thats going to a new mux8, called mux8i
[03:00:48] <jmkasunich> instead of individual input bits, mux8i takes an integer and selects one of 8 inputs
[03:01:06] <jepler> that was my guess
[03:01:19] <jmkasunich> result is a simple and clean way for a radiobutton to pick one of N analog values
[03:02:59] <jmkasunich> why are GUIs so complicated
[03:03:39] <jmkasunich> radiobuttons with titles that aren't the same length wind up not lined up
[03:03:48] <jepler> ugh
[03:03:53] <jepler> they're centered or something, aren't they
[03:04:00] <jmkasunich> the string+button as a whole is centered
[03:05:23] <jmkasunich> its also unfortunate that "choices" (list of strings) is used for both the button labels and the hal pin names
[03:05:45] <jmkasunich> that means your button labels can't include whitespace or any characters that are illegal for hal names
[03:06:30] <jmkasunich> but what matters is that it works
[03:07:04] <jepler> as the first child of <hbox>, put <boxanchor anchor="nw"/>
[03:07:29] <jepler> er, vbox
[03:07:44] <jepler> that should make the items inside stuck to the upper left corner of their box, instead of being centered
[03:08:23] <jmkasunich> are you referring to the pyvcp vbox, or a tkinter vbox?
[03:08:40] <jepler> that's a line for your xml file
[03:09:41] <jepler> hm that won't work for radiobuttons :( sorry to get your hopes up
[03:10:01] <jmkasunich> heh
[03:10:14] <jmkasunich> the vbox that the buttons live in is not from my xml file
[03:10:37] <jmkasunich> I just tried putting the radiobuttons in an hbox, and they are still arranged vertically
[03:11:43] <jmkasunich> maybe some incantation in the "pack" command?
[03:12:02] <jmkasunich> this is the code that creates the gui button:
[03:12:03] <jmkasunich> b=Radiobutton(self,f, text=str(c)
[03:12:03] <jmkasunich> ,variable=self.v, value=pow(2,n))
[03:12:03] <jmkasunich> b.pack()
[03:12:37] -!-
ve7it has quit [Remote host closed the connection]
[03:13:16] <jepler> yes
[03:13:40] <jepler> you could change it to b.pack(anchor="nw") if you don't care about disturbing anybody else's pretty gui
[03:16:02] <jmkasunich> I tried side=LEFT, and got all my buttons in a single row, left to right
[03:16:43] <jmkasunich> I guess side = left means "at the left of the remaining space", not "vertically along the left edge of the box"
[03:17:21] <jmkasunich> the anchor worked
[03:18:34] <jepler> yes, that's roughly right
[03:25:06] <jmkasunich> since I'm butchering my copy of pyvcp anyway...
[03:25:47] <jmkasunich> jepler: is there a convenient python method that takes a string which might contain whitespace, and returns only the substring before the first whitespace character?
[03:25:56] <jmkasunich> ( I should be asking the internet, not you....)
[03:31:10] <jepler> jmkasunich: s.split()[0]
[03:31:19] <jepler> though if s consists of only whitespace, that'll result in an exception
[03:31:36] <jepler> >>> s = "what was that"
[03:31:37] <jepler> >>> s.split()[0]
[03:31:37] <jepler> 'what'
[03:31:42] <jmkasunich> well, if s consisted only of whitespace, it would have resulted in a hal pin creation error anyway
[03:31:57] <jmkasunich> the internet told me to use split, I was just about to try it
[03:32:02] <jmkasunich> thanks tho
[03:32:05] <jepler> >>> head, tail = s.split(None, 1)
[03:32:05] <jepler> >>> head, tail
[03:32:05] <jepler> ('what', 'was that')
[03:32:19] <jepler> just in case you want the rest ^^^ but then it's an error if the string doesn't have at least one space
[03:32:50] <jmkasunich> don't want the rest - this is to let me use a string with whitespace as the button label, the first word will become the hal pin name
[03:32:59] <jepler> ok
[03:33:12] -!-
micges has quit [Quit: Ex-Chat]
[03:34:00] <jmkasunich> I'm a dumbass
[03:34:09] <jepler> if ' ' in c: pinname, pintext = c.split(None, 1) / else: pinname = pintext = c
[03:34:18] <jmkasunich> I put the split in the wrong place - so the label is now one word, but the hal name has spaces in it
[03:34:26] <jepler> this is what I was thinking: if there's a space, take the part after the space as the text and the part before as the name
[03:34:50] <jmkasunich> ah, so you can make them completely independent
[03:35:17] <jepler> right
[03:42:26] <jmkasunich> works great
[03:44:10] <jepler> 'night
[03:46:41] <KimK> jmkasunich: Hi John. I was scrolling back, I had to alternately nest vboxes and hboxes to get my pyvcp doodads to stack the way I wanted. Maybe you've got it fixed already.
[03:48:23] <KimK> Oh, I see, it's radiobuttons that only appear vertically? Nevermind then.
[03:50:51] <jmkasunich> yeah, we were talking about the packing of the individual buttons in a single radiobutton widget

[18:15:02] <JT-Shop> how do you test build the packages locally to verify or do you mean build a RIP?
[18:18:05] <seb_kuzminsky> JT-Shop: in the top-level directory, run "fakeroot debian/rules binary", or some folks prefer to use debuilder but I don't know the full command-line for that off the top of my head
[18:18:29] <JT-Shop> ok, thanks
[18:21:16] <JT-Shop> what should it return?
[18:24:44] <JT-Shop> I get file not found, should it be fakeroot depian/rules.in binary ?
[18:27:57] <psha> no
[18:28:03] <psha> you should generate debian/rules first
[18:28:11] <psha> cd debian; ./configure sim/rt(?)
[18:28:48] <JT-Shop> psha: thanks
[18:31:02] <JT-Shop> ./configure sim or -r :)
[18:32:19] <andypugh> Isn't it --enable-simulator or is that something else?
[18:32:59] <JT-Shop> that's for a RIP andypugh
[18:33:16] <JT-Shop> this is in /debian
[18:36:07] <psha> andypugh: something else
[18:36:18] <psha> that's configuration of debian package scripts
[18:36:32] <psha> which call ./src/configure with appropriate flags
[18:36:58] <andypugh> Right, good job nobody was taking any notice of my advice then :-)
[18:37:32] <JT-Shop> ohh I just found a page on the wiki with some suspect links

[19:40:28] <mhaberler> JT-shop: typo fixed, thanks
[19:41:42] <mhaberler> we need a simple way for folks installing from source such that all dependencies are installed
[19:42:03] <mhaberler> this is an ongoing hit and miss game, and endless source of support issues and confusion
[19:42:46] <mhaberler> it would be great if at least configure were able to say 'to run this you need to apt-get install x y z'
[19:44:39] <micges> sudo apt-get build-dep emc2?
[19:45:33] <mhaberler> configure should say whatever needs to be done. Its fine you know - Joe chipmaker doesnt
[19:45:56] <micges> but I think it doesn't install all needed
[19:46:08] <mhaberler> it should *detect* if something is missing
[19:46:23] <micges> so only ./configure
[19:46:38] <mhaberler> and it should say *what* it is, and *how* it can be resolved
[19:47:27] <mhaberler> if it bytes cradek, it is posititvely broken

[23:40:44] <jepler> configure should not check for runtime-only deps
[23:41:01] <jepler> for example, say we considered X a runtime dep
[23:41:04] <jepler> we shouldn't require X to build
[23:42:03] <jepler> (if configure did check, it'd make every runtime-only dependency into a build-time dependency, and that subverts the purpose of letting some runtime dependencies not be installed at build-time)
