[11:30:07] <mhaberler> hi all - anybody out here willing to discuss interpreter internals?
[11:30:47] <archivist> just throw the question in then a lurker can answer
[11:33:10] <psha> mhaberler: you'd better wait till 13 GMT when jeff will be up
[11:52:37] -!- psha has quit [Quit: Lost terminal]
[11:52:39] <mhaberler> ok, so.. subject is interpreter instantiation and state
[11:52:41] <mhaberler> In theory the Interpreter is an instance object
[11:52:42] <mhaberler> however, state is really global, and has the following components:
[11:52:44] <mhaberler> 1. the 'world model' (machine actual state?), in the _setup static member struct
[11:52:45] <mhaberler> 2. the interpreter execution state (current block, stack, filedescriptors, o-word handling auxiliary structures etc)
[11:52:47] <mhaberler> 3. the interpreter list of generated NML messages
[11:52:48] <mhaberler> 1+2 are lumped together in setup_struct
[11:52:50] <mhaberler> 3 - there's really just a single list on which task operates.
[11:52:51] <mhaberler> Let's assume I'd like to create a new interp instance to execute something in the middle of a block, like replacing a Tx or M6 by an oword sub call
[11:52:53] <mhaberler> I want it to inherit the world model, execute a subroutine, which might modify the world model, and terminate, but I would NOT want it to modify otrher interp instances execution state
[11:52:55] <mhaberler> now to actually make that usable, the new instance needs to inherit the current world model (1) (or synch with it), AND get a disjunct execution state descriptor as to not trample on the other interpreter's internal state
[11:52:56] <mhaberler> that is currently impossible because world model and interp state are in a single structure - read as: yes, it's a class, but no, another instance doesnt give you an independent execution context
[11:52:58] <mhaberler> so world model and interp state need to be separated into different structs; world model=static member, state = instance attribute; this might mean extra parameters to many functions
[11:53:00] -!- HDB10 has quit [Quit: Ex-Chat]
[11:55:55] -!- ries [ries!~ries@200.125.129.54] has joined #emc-devel
[11:58:41] <mhaberler> anywhere making sense yet ;-?
[12:07:16] <archivist> I think so and that seems a traumatic change
[12:10:09] <archivist> are you trying to add separate interpreters for n axes
[12:11:25] <archivist> or a detect worn tool stop pull out change return to previous state
[12:11:30] <mhaberler> not on axes; I want to startup a pristine execution context in the middle of a block execution - goal is to replace arbitrary codes by o-word sub calls but for now I limit myself to replacing Tx and M6
[12:12:45] <archivist> replace arbitrary codes by o-word sub calls seems a text replacement to the raw gcode is all thats needed
[12:17:25] -!- Dallur has quit [Quit: Leaving.]
[12:26:15] <mhaberler> that's what I thought, too, unfortunately it aint so
[12:26:17] <mhaberler> a 'block' is parsed into a block structure, and then that stuff is executed in a given order
[12:26:19] <mhaberler> that means that you need to be able to call a sub during a block execution
[12:26:20] <mhaberler> and that tramples on the state of the current block
[12:26:22] <mhaberler> which is why I want to separate out the state
[12:28:55] <mhaberler> the other show stopper here is that there's a limitation of one oword call per block
[12:29:16] <mhaberler> that I can get rid of by using a new interp instance
[12:30:44] <archivist> if you text replace, then you are adding blocks not clobbering the current one, still not sure the real application yet
[12:32:35] <archivist> yes some modal setting will be clobbered though
[12:34:13] -!- Valen has quit [Quit: Leaving.]
[12:50:02] -!- psha [psha!~psha@213.208.162.69] has joined #emc-devel
[13:15:04] <mhaberler> that's the issue
[13:15:06] <mhaberler> modal settings are interp state, not part of the world model
[13:16:08] <mhaberler> the goal is to optionally replace the toolchange support (Tx,M6,M61) by o-word subroutines in g-code
[13:35:23] -!- skunkworks [skunkworks!447329d2@gateway/web/freenode/ip.68.115.41.210] has joined #emc-devel
[13:43:30] <jepler> mhaberler: I have no idea why _setup is static
[13:44:11] <mhaberler> well it works just fine with making it an instance variable
[13:45:01] <mhaberler> that's sort of the cheap solution
[13:45:03] <mhaberler> the clean solution would be to separate world model and interpreter state
[13:45:49] <mhaberler> it is major lobotomy though
[13:46:38] <jepler> Interp::synch is supposed to update anything that is external as opposed to interpreter state
[13:47:44] <jepler> unfortunately, I don't think you could call anyone on the project an expert on the interpreter structure :-/
[13:48:40] <mhaberler> re structure.. its a bit arcane, yes
[13:48:42] <mhaberler> re sync..right.. well either I instantiate a new interp with the current :_setup as parameter or interp::synch it, should be pretty much the same effect I guess
[13:49:26] <mhaberler> "pretty much the same" like "a bit pregnant"
[13:50:00] -!- elmo40 has quit [Ping timeout: 276 seconds]
[13:50:48] <mhaberler> cloning the setup would alleviate going through inifile, param restore, initial gcodes etc - basically just an independent throwaway copy of the previous interp
[13:52:05] -!- izua has quit [Ping timeout: 276 seconds]
[13:52:13] <psha> mhaberler: most of structures in _setup are defined 'in place' and not with pointers
[13:52:21] <psha> so plain 'memcpy' will move lot of stuff
[13:52:34] <jepler> use operator= to copy structures
[13:52:40] <psha> and you'll need to adjust only stack and friends
[13:52:51] <psha> ah, forgot that it's C++ :)
[13:53:07] <jepler> setup saved_state = _setup; ....; _setup = saved_state
[13:53:25] <jepler> if it becomes useful later to actually define an operator= that does something smarter than a bytewise copy, you can do it..
[13:54:10] <mhaberler> ah, good idea
[13:54:12] <mhaberler> stack: good point, I missed that one
[13:54:13] <mhaberler> I though I saw something about interpreter regression ..
[13:54:33] <jepler> there are interpreter tests
[13:54:37] <mhaberler> regression testing - any pointers? I think the saicanon stuff serves that, right?
[13:54:41] <jepler> you can run the bundled tests this way: . scripts/emc-environment; runtests
[13:54:49] <mhaberler> ah, thanks
[13:55:08] <jepler> yes, the interpreter tests use the 'rs274' program which is from src/emc/sai
[13:55:46] <jepler> look at an existing test like tests/interp/crazy-paths if you want to create your own that exercise toolchange
[13:56:15] <mhaberler> ok, I'll see wether I can get by making _setup an instance attribute (is this proper c++ speak? is it a 'member variable'? dunno) and save/restore that, that should be most of the milage
[13:56:36] <mhaberler> actually I'm pretty sure that would work
[13:56:38] <psha> mhaberler: no difference how to call it if others understand you ;)
[13:56:53] <jepler> I see one unfortunate thing about doing that: it seems to mean you have to include interp_internal.hh in rs274ngc_interp.hh
[13:57:02] <mhaberler> yes, did that already
[13:57:05] <jepler> because the definition of the setup struct has to be available then
[13:57:25] <mhaberler> or that goes to a separate include just for that purpose
[13:57:52] <mhaberler> it could be private anyway
[13:58:33] <psha> jepler: or use forward declaration
[13:59:00] -!- micges_work [micges_work!~x@aejb205.neoplus.adsl.tpnet.pl] has parted #emc-devel
[13:59:04] <mhaberler> doesnt have the size to be known?
[13:59:15] <jepler> 1 struct incomplete;
[13:59:15] <jepler> 2 struct wont_compile {
[13:59:15] <jepler> 3 incomplete i;
[13:59:15] <jepler> 4 };
[13:59:19] <jepler> incomplete.cc:3: error: field ‘i’ has incomplete type
[13:59:26] <psha> incomplete &i; incomplete *i;
[13:59:31] <jepler> you can't declare a struct or class member that is an incomplete type
[13:59:41] <mhaberler> been there..
[13:59:45] <jepler> you can declare a static class member that is incomplete..
[14:00:13] <mhaberler> aja, that's why that worked, and maybe that's the reason why it was declared static in the first place
[14:00:18] <jepler> well, it is not a showstopper to add the required include there
[14:00:33] <jepler> it just makes me a bit sad
[14:01:37] <mhaberler> well, lets see wether it works and then there will be some upside to counter them tears ;-)
[14:01:57] <jepler> it looks like you can't specify an inifile with the standalone rs274
[14:02:07] <jepler> that'll make it tough to test this feature from the testsuite :-/
[14:03:42] <mhaberler> hm, well I need to explore the regression test first
[14:03:43] <mhaberler> anyway, I gotta run for some unfortunate real-life stuff - thanks very much for the hints, it's fairly clear for me how to proceed!
[14:03:51] <jepler> best of luck
[14:04:01] <jepler> with emc and real life both
[14:04:11] <mhaberler> hm, I understand now why 'cradek let me do it'
[14:04:36] <mhaberler> I'm now at throwaway branch #5;-)
[14:04:51] <jepler> beats doing it in cvs
[14:05:06] <jepler> where you can never organize your thoughts without letting the central authority know
[14:05:10] * jepler bbls too
[14:05:18] <mhaberler> anytime, still its more meandering like software engineering
[14:05:36] <mhaberler> cu!
[14:05:37] <psha> jepler: i've send mail to dev list with a short summary of 'research' on docs format and it seem that all mentioned requirements may be done with asciidoc
[14:05:56] <jepler> psha: that's great, I've secretly wanted asciidoc all along
[14:06:07] <mhaberler> psha: thanks for doing that..
[14:06:12] <cradek> me too
[14:08:41] <psha> so i guess if migration is approved i'll start working on convertor

[14:23:50] <archivist> psha, and then... if I can get a list of anchors for the html !man g76 becomes possible from the bot
[14:24:20] <archivist> !man25 g76 to go to a particular version
[14:25:06] <archivist> it carries a root url to base a versions docs
[14:25:18] <archivist> table or root urls
[14:26:53] <psha> what exactly do you need? list of section names with URL's?
[14:28:20] <archivist> for mysql I read the xml and pull anchors and page titles and index terms, and give those a priority
[14:29:57] -!- drill has quit [Ping timeout: 240 seconds]
[14:30:32] <archivist> I then keep tables to create the replies, I keep the http://linuxcnc.orc/docs/2.5 separate from title , pagehtmlname
[14:31:45] <archivist> title being the term we are searching for, the taught items are for wiki type pages which dont have structure
[14:35:04] <archivist> so section header names as anchors, page titles, and any special index terms that should go to a particular page

[14:41:51] -!- nullie has quit [Read error: Connection timed out]
[14:41:54] <archivist> are you converting lyx to docbook or asciidoc to docbook as an output

[14:43:58] <archivist> I should learn xslt really
[14:44:09] <archivist> black art though
[14:46:04] <psha> but really it's possible to write small asciidoc config for custom output
[14:46:15] <psha> which would ignore everything except sections

[14:46:46] <psha> jepler: lyxtree converts LyX to XML 1 to 1?
[14:49:35] <jepler> I suspect there are some things lyxtree ignores or skips over.. so I would hesitate to call it 1 to 1
[14:53:53] <jepler> cradek, andypugh: it looks like the hostmot2 additions were incomplete.. sserial.c seems to be missing
[14:54:04] <jepler> buildbot encounters an error and so do I
[14:54:12] <seb_kuzminsky> yeah, the build failed, but the failure email didn't make it onto the list

[17:28:54] <jepler> er, to asciidoc
[17:33:04] <psha> yes
[17:33:14] <psha> thanks to asciidoc simplicity ;)
[17:34:01] <jepler> I tried to view the .txt to see how natural or unnatural it looks, but it's not there

[17:41:41] <psha> i guess with a small risk of breaking anchors, xrefs and friends it would be simple

[19:09:10] <andypugh> To save any trouble with incompatibility with the "old" gearchange.comp, how about calling the "new" one just "gear"?
[19:09:40] <andypugh> (I am generally in favour of anything to reduce typing in HAL files)
[19:15:03] <jepler> andypugh: after your recent hostmot2 changes, master doesn't build. can you look into it and get another patch to apply on top of all the rest to get things working again?
[19:15:39] <andypugh> Oh.

[19:17:30] <andypugh> sserial.c isn't in the patch file.
[19:17:39] <jepler> yeah that would do it
[19:18:19] <jepler> psha: no, axis-remote uses two dashes just like any sane gnuish program

[19:35:14] <psha> yes
[19:35:27] <jepler> :(
[19:35:27] <psha> some thinks (like enums, itemizations) are nestable

[19:51:28] <andypugh> OK, should I send it to the list, or do you want it?
[19:51:36] <jepler> privately is fine

[19:52:58] <psha> hal/comp.lyx looks like excersises in different font options...
[19:54:05] <jepler> it's been a long while since I used dcc
[19:54:07] <andypugh> jepler: Can you see if it fixes things locally first? My confidence in my ability to prodice working patch files is very, very low.
[19:54:30] <jepler> the build runs to completion
[19:54:54] <andypugh> That's a start, at least
[19:55:11] <andypugh> I will pull a new master and check for function
[19:55:30] <jepler> thanks
[19:55:42] <CIA-2> EMC: 03jepler 07master * r50bd2c1ce86c 10/src/hal/drivers/mesa-hostmot2/sserial.c: missing file: sserial.c
[19:55:44] <jepler> …pushed
[19:57:47] <jepler> if it makes you feel any better, at my day job we use git and I recently broke the development tree by making the same error (not committing a newly-created file)
[20:04:15] <andypugh> The odd thing is that cradek noticed a problem with the bldc.comp patch, but not with the main one, before he pushed them for me.
[20:04:36] <jepler> he built on sim only
[20:04:47] <jepler> so a hardware driver like hostmot2 wasn't built at all
[20:04:52] <andypugh> Ah, yes, that would do it.
[20:05:46] <cradek> sigh
[20:09:42] <andypugh> How can I get back to a normal, clean, master branch? I can't pull at the moment because of:
[20:09:43] <andypugh> error: Untracked working tree file 'configs/common/shuttlexpress.hal' would be overwritten by merge. Aborting
[20:10:07] <andypugh> I am tempted to just delete my whole git repo and start again. It's a mess
[20:10:55] <andypugh> (Applying patches in the wrong level of the tree hasn't helped at all)

[20:22:16] <psha> git reset --hard
[20:22:18] <psha> git clean -fd

[20:22:35] <andypugh> That's OK
[20:22:56] <psha> first resets all known files to HEAD
[20:23:04] <psha> second removes all unknown files and dirs
[20:23:19] <andypugh> Perfect
[20:23:29] <andypugh> Now to delete all my branches
[20:23:41] <psha> git branch -d branch-name
[20:23:47] <psha> or -D if it's not merged
[20:24:05] <andypugh> Ah, that last bit is what I have been missing
[20:26:41] <andypugh> Still can't pull master.
[20:26:54] <andypugh> error: Untracked working tree file 'lib/python/gladevcp/hal_mdihistory.py' would be overwritten by merge. Aborting
[20:28:16] <psha> ah
[20:28:20] <psha> it don't respect .gitignores
[20:28:39] <andypugh> I am sure that git is briliant, if you can get your head around how it works. It doesn't appear that I can.
[20:28:39] <psha> you have to kill that file by hand
[20:28:54] <andypugh> I wonder how many others?
[20:29:07] <psha> you applied some patches (but not commited them)
[20:29:17] <psha> but files from them are ignored (by gitignore)
[20:29:31] <psha> git clean -fdx
[20:29:48] <psha> -x remove ignored files, too
[20:32:02] <psha> jepler: i've managed to fix nearly everything except nested verbatim blocks
[20:32:10] <andypugh> OK, so this is my own fault at least:
[20:32:11] <andypugh> Auto-merging src/hal/components/bldc.comp
[20:32:11] <andypugh> CONFLICT (add/add): Merge conflict in src/hal/components/bldc.comp
[20:32:11] <andypugh> Automatic merge failed; fix conflicts and then commit the result.
[20:33:24] <psha> you've got two copies of your patches
[20:33:27] <psha> one sitting in your repo
[20:33:36] <psha> second applied by criss&jeff
[20:33:50] <andypugh> Probably.
[20:33:52] <psha> one possible way is to use 'rebase' instaead of merge
[20:34:01] <psha> git rebase -i origin/master
[20:34:13] <andypugh> Or I could just re-clone the repo
[20:34:16] <psha> then mark patches you don't need
[20:34:21] <andypugh> Or nuke the site from orbit
[20:34:24] <psha> or just drop this branch ;)
[20:34:35] <psha> git branch -M tmp
[20:34:40] <psha> git checkout -b master origin/master
[20:34:43] <psha> git branch -D tmp
[20:35:49] <andypugh> Aha!
[20:36:13] <andypugh> I even understood what you were doing there
[20:36:44] <psha> that's how i do my gladevcp branches
[20:37:07] -!- toastydeath has quit [Quit: Leaving]
[20:37:09] <psha> prepare lot of feature branches, then merge them in one, ask jeff to pick it and then drop
[20:39:12] <andypugh> My main problem is a tendency to fiddle around with something to see if it works, then realise that I didn't create a banch for it, so it is all mixed up with something else.
[20:42:08] <psha> you may branch whenever you want
[20:42:15] <psha> it's not mercurial with commit-bounded branches
[20:42:26] -!- ries has quit [Ping timeout: 240 seconds]
[20:42:48] <psha> for example if you are in situation where you changed two files (with two different features) and want to branch only one
[20:42:53] <psha> run git stash -p
[20:43:13] <psha> it will ask you what changes you want to stash - select features you don't want to branch
[20:43:24] <psha> then git checkout -b cool-feature
[20:43:28] <psha> commit there
[20:43:31] <psha> checkout back
[20:43:33] <psha> and git stash pop
[20:43:59] <psha> so you'll split you large change into smaller and in different branches
[20:44:28] <andypugh> Clever. And baffling.
[20:45:15] <psha> like any tool - like mobile phone, hammer or even spoon, you have to explore it's possiblities first...
[20:45:38] <psha> for example i've used my spoon several years ago to dig to the water ;)
[20:46:57] <andypugh> I am about to install Autodesk Inventor on my Mac in a Virtual Machine. I can see that working poorly :-)
[20:50:45] <psha> jepler: what's "ert" tag?
[20:51:13] <jepler> psha: "The acronym ERT (Evil Red Text) refers to raw LaTeX commands inserted into the body of your LyX document"
[20:54:23] <jepler> for instance, \clearpage (go to next page) is an ERT, and it is just omitted in the html translation
[20:54:54] <jepler> <xsl:template match="ert"/>
[20:55:06] <jepler> yeah, that's the xsl rule for ERTs .. they are just ignored by the html conversion
[20:56:31] <psha> :D
[20:56:39] <psha> so i'll do the same...
[20:56:42] <psha> another question
[20:56:47] <psha> http://www.linuxcnc.org/docs/devel/html/hal_components.html#sec:Commands-and-Userspace-Components
[20:56:54] <psha> here is strange itemize
[20:56:57] <psha> with bullets and =
[20:57:06] <psha> in LyX xml it looks like
[20:57:11] <psha> <item><labelwidthstring data="00.00.0000"/>= AXIS Remote Interface</item>
[20:57:19] <psha> i guess it's safe to ignore labelwidthstring
[20:57:26] <psha> since it's all zeroes ;)
[20:58:11] <jepler> huh
[20:59:10] <psha> hm
[20:59:14] <psha> another dumb
[20:59:15] <psha> one
[20:59:24] <psha> i've seen several 'pagebreak_bottom' tags
[20:59:39] <psha> but i guess they are not really intended to be 'hard page breaks'
[20:59:48] <psha> <layout class="Standard">Make sure the loadusr line is before any net's that make use of the pyVCP<pagebreak_bottom/> pins.</layout>
[21:00:03] <psha> forcing page break with one word left....
[21:00:04] <psha> ;)
[21:01:33] <jepler> huh, I have no idea what's gong on with that stuff in components.lyx
[21:04:34] <jepler> well, it's function ListFixer in lyxtree.py that loses the first word
[21:05:42] <jepler> \layout List
[21:05:42] <jepler> \labelwidthstring 00.00.0000
[21:05:42] <jepler> 1.
[21:05:42] <jepler> Widgets de signalisation, signaux BIT: led, rectled
[21:06:04] <jepler> in the files I tested, I think that the first word was the index in the list, which you don't want to include in the output...
[21:06:06] <psha> i guess it's safe to ignore it
[21:07:46] -!- ries [ries!~ries@200.125.129.54] has joined #emc-devel
[21:07:57] <jepler> probably comment out the call to ListFixer for the purposes of confusion
[21:08:06] <jepler> er, for the purposes of *conversion*
[21:10:42] <psha> another one
[21:10:44] <psha> http://www.linuxcnc.org/docs/devel/html/gui_mini.html#r1_4_1
[21:10:52] <psha> here are many 'Quotations'
[21:11:05] <psha> indented blocks with Quotation layout class
[21:11:12] <psha> how to deal with them?
[21:11:22] <psha> treat them as asciidoc quotations?
[21:11:24] <jepler> in this case? it looks like it's not even desired
[21:12:05] <psha> there is footnote
[21:12:06] <psha> 1 Much of this chapter quotes from a chapater of the Sherline CNC operators manual. back
[21:12:10] <psha> so maybe it's really quotation
[21:13:43] <jepler> If the text is free to incorporate into our documentation because the sherline manual is also GFDL then we should just incorporate it.
[21:14:02] <jepler> if we're not free to incorporate it willy-nilly, I'd rather the text jettisoned and something original written in its place
[21:14:39] <psha> ok, so i'd drop quotation after conversion

[21:16:25] <psha> same here
[21:17:10] <jepler> here I think using a block quotation is sensible
[21:17:30] <psha> there are 4 files with Quotation layouts
[21:17:32] <jepler> (well, except that "For exmaple, the Gecko G202 manual says this:" shouldn't be inside the block)

[22:43:41] <garage_seb> basic wiring question from a helpless software geek...
[22:43:53] <garage_seb> i'm wiring up a bunch of buttons on the control panel on my mill
[22:44:12] <garage_seb> it's about a 6' cable run to the 7i37 isolated i/o board in the electronics cabinet
[22:44:25] <garage_seb> i'm using cat5 cables (utp) because that's what i have handy
[22:45:06] <garage_seb> question: is it ok to run just one ground line from the back to the front, then spider it out to all the buttons on the panel?
[22:45:41] <cradek> 24v?
[22:45:48] <garage_seb> cradek, yes
[22:45:56] <andypugh> You mean 0V or ground/shield?
[22:45:56] <garage_seb> the buttons are momentary, and i'm thinking each gets its own signal wire but a shared ground
[22:46:07] <garage_seb> it's logic ground
[22:46:15] <cradek> probably deosn't really matter...
[22:46:16] <garage_seb> not the wire shield
[22:46:37] <andypugh> It'll be fine, and if not, fix it in software :-)
[22:46:54] <garage_seb> yeah i was thinking it'd be safe to do, but i didn't have a lot of confidence in that thought :-)
[22:47:00] <garage_seb> ok next question
[22:47:18] <garage_seb> each wire consists of four twisted pairs
[22:47:21] <cradek> I'd probably run a pair to each button, to make it all nice though
[22:47:48] <garage_seb> is it ok to run different buttons on the two wires of a pair?
[22:48:01] <garage_seb> or should i just not try to optimize my wire count and run a pair to each button?

[22:48:07] <cradek> it's just buttons...
[22:48:09] <andypugh> It's a DC signal, so I would say yes.
[22:48:10] <cradek> brb
[22:48:27] <garage_seb> ok thanks guys :-)
[22:48:39] <psha> garage_seb: if you don't want to control stepper with button presses then what's problem?
