| 00:05.48 | pacman87 | the sketch is revolved about its y-axis, which i told revolve to line up with the 3d Z-axis |
| 00:06.22 | louipc | cool |

| 00:42.54 | brlcad | poolio: yahoo! .. pics?! :) |
| 00:46.23 | brlcad | pacman87: interesting closure on the base -- does it stay open if the base of those two segments line up perfectly? do they line up now? |
| 00:47.41 | brlcad | if they do line up, that's the one case I might have expected it to stop at the inner segment |
| 00:50.56 | poolio | brlcad: err...it looks exactly the same as brep_cube/breplicator/etc... |
| 00:52.03 | poolio | I'm working on generalizing to not just 4-sided things now. Is there a way to define surfaces shaped like say, triangles? I know there is...I'm just not quite sure how :) The approach I was going to do was creating a rectangle that encloses the area and cutting out of that. |
| 00:52.06 | brlcad | ah, k |
| 00:53.19 | brlcad | that example file I pointed you at made a triangle.. |
| 00:54.36 | poolio | Yes, but it did so by creating a rectangular suface and trimming a triangle |
| 00:55.04 | brlcad | pacman87: oh, I see what you did now .. never mind :) |
| 00:55.16 | brlcad | the rt is "upside down" from what I thought I was looking at |
| 00:58.11 | pacman87 | brlcad: yeah, they stop because on the inside, it's a zero length hit segment, so i ignore it |
| 01:04.49 | brlcad | oh.. heh, I was thinking that if you draw lines from the endpoints to the y axis, the wider base ends up connecting the two edges on the outside leaving the base open yet the narrow top has a clear path the the y axis for both segment endpoints so you end up with a thick top |
| 01:09.24 | brlcad | from a 'top' view, render rt -k 0,0,1,0 .. what does that look like? |
| 01:10.01 | pacman87 | lookign down along Z? |
| 01:11.31 | pacman87 | two circles |
| 01:11.39 | pacman87 | bright white center, grey outside that |
| 01:12.08 | pacman87 | *two concentric circles |
| 01:15.20 | brlcad | erm |
| 01:15.35 | brlcad | you said https://webspace.utexas.edu/trv82/www/rev_wf05.png is rotating around the +Y axis? |
| 01:15.54 | pacman87 | that is the sketch |
| 01:16.00 | brlcad | cutting +z should cut it in half (a "C") |
| 01:16.22 | pacman87 | it rotates about the sketch's y axis |
| 01:16.32 | pacman87 | the 3d axis is 0,0,1 |
| 01:16.38 | brlcad | ahhh |
| 01:16.53 | brlcad | so left view with 0,1,0,0 |

| 01:43.47 | brlcad | wierd black line... |
| 01:44.03 | brlcad | if that's straight-on, it's probably a bug |
| 01:44.42 | brlcad | normal going the wrong way on grazing or something |
| 02:16.09 | pacman87 | no, it's a little above |
| 02:16.19 | pacman87 | straight-on is buggy |
| 02:16.39 | pacman87 | so is looking along the revolve axis |

| 02:30.21 | brlcad | cool |
| 02:30.49 | pacman87 | is there a way to choose 'X' from commandline after -c? |
| 02:47.12 | poolio | brlcad: hmm...so code works with rectangular faces...triangles make it blow up for some reason :\ |

| 03:15.48 | brlcad | poolio: ahh :) |
| 03:16.05 | pacman87 | attach (nu|X|ogl)[nu]? |
| 03:17.34 | brlcad | ooh, *mged* -c .. was thinking rt -c :) |
| 03:22.05 | brlcad | yes, either answer X at the attach prompt or run "attach X" afterwards |
| 03:23.00 | pacman87 | i was hoping for a one-line way to start mged so i could skip the prompt |
| 03:23.22 | pacman87 | /usr/brlcad/bin/mged -c ~/brlcad/test/open.g |
| 03:23.50 | brlcad | ahh, interesting |
| 03:23.51 | pacman87 | if it's possible to have -c take an argument |
| 03:24.00 | brlcad | don't think anyone has ever asked that :) |
| 03:24.02 | pacman87 | /usr/brlcad/bin/mged -c X ~/brlcad/test/open.g |
| 03:24.16 | pacman87 | well, i restart mged every time i compile |
| 03:24.34 | brlcad | no, at least not optionally and still be able to tell the diff with a filename arg that optionally follows |
| 03:25.08 | pacman87 | what about just -X instead of -c |
| 03:25.29 | brlcad | i do too, but mged -c file.g[enter][enter] does the trick for me ;) |
| 03:26.08 | pacman87 | it defaults to nu, right/ |
| 03:26.09 | poolio | brlcad: So I failed a bit on some basic geometry stuff. I'm trying to enclose a face in a rectangular surface. I want to compute 2 points on the plane that will be the lower left/upper right of the rectangle. Is there an easy way of doing this? |
| 03:26.09 | pacman87 | ? |
| 03:26.48 | brlcad | -x and -X are taken, they are debug options for almost every one of brl-cad's apps |
| 03:26.58 | pacman87 | -cX? |
| 03:27.07 | brlcad | librt and libbu respectively |
| 03:27.58 | brlcad | -cX is no different than -c -X |
| 03:28.08 | pacman87 | --cX? |
| 03:28.15 | brlcad | (think tar -xvf == tar -x -v -f |
| 03:28.23 | pacman87 | yeah, i forgot about that |
| 03:29.45 | brlcad | could maybe add "-a display_manager", e.g. -a X |
| 03:30.02 | brlcad | or take over the deprecated -n |
| 03:30.38 | pacman87 | would that imply -c? |
| 03:30.58 | pacman87 | ie, would specifying the display manager make sense for non-classic mode? |
| 03:37.21 | starseeker | brlcad: Random mostly off topic question - what's the leading finite element library with a license compatible with BRL-CAD? |
| 03:42.40 | brlcad | right now -c == -n and both are optionless |
| 03:43.37 | brlcad | but yeah, a -a would imply -c |
| 03:44.23 | brlcad | starseeker: why our own libfem of course! |
| 03:44.49 | starseeker | :-) |
| 03:44.52 | brlcad | depends, you wanting meshing, analysis, or both? |
| 03:45.05 | brlcad | open soure fea/fem sucks |
| 03:45.49 | starseeker | was thinking anything we don't have that we would need to do in-BRL-CAD analysis... |
| 03:46.12 | starseeker | notes that the first hit on google for libfem is the mailing list for Liberty and Feminism |
| 03:46.55 | brlcad | gmesh is probably one of the better fem tools, i've heard of impact for fea but not looked into it |
| 03:47.26 | brlcad | they're about as far away from high-end commercial fea codes as we are from full-blown catia |
| 03:48.34 | starseeker | ow |
| 03:48.57 | brlcad | pacman87: not pertinent to what you're needing, but if you didn't know -- you can add a command after the .g file and mged will run it |
| 03:49.02 | starseeker | Is openFEM worth anything? |
| 03:49.03 | brlcad | and then quit.. |
| 03:49.25 | brlcad | could add a mod to make certain commands keep mged running |
| 03:49.39 | brlcad | ones (like attach) that make no sense as single-action commands |
| 03:49.47 | brlcad | so this would work: mged -c brlcad/db/moss.g attach X |
| 03:50.37 | pacman87 | can you do multiple commands? |
| 03:51.49 | brlcad | mged -c brlcad/db/moss.g "attach X ; puts hello" |
| 03:52.41 | brlcad | alternatively, it'll take stdin too so you can batch commands together |
| 03:53.03 | brlcad | e.g. mged -c blah.g <<EOF |
| 03:53.04 | brlcad | tops |
| 03:53.06 | brlcad | whatever |
| 03:53.08 | brlcad | EOF |
| 03:53.43 | brlcad | or put that in some mged_script and "mged -c blah.g source mged_script" instead |
| 03:54.03 | brlcad | starseeker: yeah, they're pretty good |
| 03:54.16 | brlcad | not so much a tool but set of routines |
| 03:54.31 | starseeker | Ah |
| 03:55.30 | starseeker | guesses this sounds like a situation where maybe we will end up creating a libfem :-) |
| 03:55.34 | brlcad | inria's pretty intense in their research |
| 03:55.50 | brlcad | they're a research powerhouse |
| 03:55.55 | starseeker | :-) |
| 03:57.48 | starseeker | groans as he updates his gentoo profile and starts one more round of re-compiles... |
| 03:58.46 | starseeker | 'course, Mike is already working on some FEM stuff, IIRC... |
| 04:01.14 | brlcad | inria is the source of gems like OCaml and SmartEiffel |
| 04:01.29 | brlcad | oh, and you probably know of coq and scilab |
| 04:01.31 | starseeker | Ah, yes - Scilab too, IIRC |
| 04:01.35 | starseeker | heh - yep |
| 04:01.53 | starseeker | coq is amazingggggggggg |
| 04:02.20 | brlcad | yeah, mike hooked an importer into sandia's cubit |
| 04:02.42 | brlcad | cubit is pretty snazzy, they have one of the *best* mesher libs |
| 04:03.19 | brlcad | and one of the best low-budget fem tools (alas not fully open source nor free) |
| 04:03.27 | brlcad | though their geometry lib is lgplg |
| 04:03.50 | brlcad | there mesh lib is the bread n' butter, though, and they're not letting go |
| 04:04.08 | starseeker | hmm - is there any chance at all they can be made to see reason? |
| 04:04.35 | brlcad | only if someone(tm) hooked brl-cad into their backend as the geometry format and geometry engine |
| 04:05.02 | brlcad | they have to charge "something" for cubit as they use the ACIS engine |
| 04:05.12 | starseeker | oh |
| 04:05.18 | brlcad | licensing issues |
| 04:05.21 | starseeker | googles ACIS |
| 04:06.56 | starseeker | hmm. Would they be supportive of a port or fight the idea? |
| 04:07.11 | brlcad | hook all of our converters, librt, libged, libwdb, libbu, and libbn together into one clean unified object-oriented API, and we overlap about 75%-90% of what ACIS does, they're the big dog of CAD kernels |
| 04:08.04 | starseeker | ouch |
| 04:08.04 | brlcad | oh everyone would be supportive, sandia said they'd love it (if it worked as well/better) |
| 04:08.22 | brlcad | just a lot of work for somewhat minimal payoff and no manpower to dedicate |
| 04:08.39 | brlcad | really begs for BREP support being fully in place first as well as our OO geometry engine |
| 04:08.54 | brlcad | (next year's priority) |
| 04:09.00 | starseeker | Ah |
| 04:09.57 | starseeker | looks for his API scrubbing gear... |
| 04:11.32 | starseeker | So it makes the most sense to do BREP and the OO engine (needed anyway) and then use the new functionality + cleanup to get cubit off of the ACIS gravy train |
| 04:11.44 | starseeker | and thus take advantage of some really good code |
| 04:12.19 | brlcad | we would increase (developer) interest in BRL-CAD by more than an order of magnitude if we had an ACIS-compatible geometry kernel API |
| 04:12.44 | starseeker | Does ACIS publish the specs for their API? |
| 04:12.53 | brlcad | e.g. something that'd convert an acis call into our geometry engine, like wine |
| 04:13.10 | starseeker | nods |
| 04:13.44 | brlcad | don't think so, you'd have to (legally try to) reverse engineer it |
| 04:13.53 | starseeker | ow ow ow |
| 04:14.30 | brlcad | just guessing, I haven't searched too hard given our other priorities |
| 04:14.38 | starseeker | right |
| 04:16.02 | brlcad | really need BREP/NURBS representation working, CSG eval of NURBS working, tessellation of NURBS, LIBGED completed, and our object-oriented geometry engine working before working on that becomes a tractable semi-even-thinkable/practical task |

| 04:20.04 | brlcad | yukonbob: no, that'd be cell-shading |

| 04:20.32 | yukonbob | s/cell/cel/ |
| 04:20.49 | brlcad | nods |
| 04:21.05 | brlcad | more like the two distance falloff images on the wikipedia page |
| 04:21.28 | brlcad | (more specifically the left first, then next get the right working) |
| 04:22.07 | starseeker | Looks like at least some of ACIS has public docs, although they have some "coming soon" links to what is probably the core ACIS docs |
| 04:23.50 | brlcad | starseeker: this makes me think it's entirely closed even if you do find bits n pieces: http://www.caddigest.com/subjects/adsk_inventor/select/grabowksi_shapemanager.htm |
| 04:24.24 | brlcad | otherwise one of the other 4 billion dollar per year cad giants would have done it already |
| 04:25.27 | starseeker | hmm |
| 04:26.38 | starseeker | Depends on what he means by "expose the API" - that sounds as if they have a full version of the ACIS sources and plan to keep working based on those |
| 04:26.54 | starseeker | unless I'm reading the article wrong |
| 04:28.08 | brlcad | but that they're forced to shimmy a layer between their kernel and the acis api (so they cannot possibly be a drop-in replacement) |
| 04:29.07 | starseeker | Right, but I'm reading that as hiding the ACIS API because their license to the source doesn't let them just take it and expose it - they'd be exposing ACIS's api using ACIS's own source code behind it |
| 04:29.23 | starseeker | So they're keeping the ACIS source, but using a different API |
| 04:29.30 | starseeker | easier than a new kernel, I'd guess |
| 04:31.48 | starseeker | is hoping there is a difference between "exposing" and "implementing from scratch" the API |
| 04:33.27 | starseeker | kinda unclear though |
| 04:35.05 | starseeker | Yeah, thought so - Autodesk proposed to continue based on the ACIS code: http://www.caddigest.com/subjects/adsk_inventor/select/grabowski_buzzkross.htm |
| 04:37.06 | brlcad | yeah, i know the article was referring to multiple things |
| 04:37.35 | brlcad | regardless of them 'extending' acis or not -- the fact that they had to make their own api layer |
| 04:37.45 | starseeker | yep |
| 04:37.46 | brlcad | api == headers == some source |
| 04:38.35 | brlcad | there are acis headers for cubit, but have to specifically ask for them (and hey have clauses in them saying no redistribution) |
| 04:38.42 | brlcad | no authorized, that is |
| 04:38.53 | brlcad | er, unauthorized |
| 04:39.37 | brlcad | or even better -- just do what acis does but do it even better |
| 04:39.53 | starseeker | Right |
| 04:40.25 | brlcad | hence libged and new geometry service which begs a middle oo geometry engine |
| 04:41.16 | brlcad | yay for it finally being prioritied (started that particular crusade as a student when I started, that brl-cad needed an OO api) |

| 04:54.16 | starseeker | no one will care, but it will be fun |
| 04:54.21 | brlcad | could try to implement a helical sweep |
| 04:55.49 | starseeker | heh :-) |
| 04:57.27 | starseeker | that might be a good way to do advanced shapes like springs with elliptical wires |
| 04:59.17 | starseeker | or the spring in the lower right corner here: http://www.spring-makers-resource.net/images/compressionspringgroup.gif |
| 05:01.25 | starseeker | inserting pipes with libwdb looks to be fairly complicated all by itself |
| 05:04.16 | pacman87 | starseeker: would you be modelling the spring behavior, or jsut the position? |
| 05:04.43 | louipc | yes do the helical sweep please |
| 05:05.29 | starseeker | pcman87: Initially just the position |
| 05:05.44 | starseeker | pacman87: Behavior modeling would probably require FEM |
| 05:06.05 | starseeker | or one heck of a mathematical model |
| 05:06.16 | louipc | behaviour depends on the type of material too |
| 05:06.23 | pacman87 | i was thinking more in terms of F = -kx |
| 05:06.25 | starseeker | exactly |
| 05:06.51 | starseeker | pacman87: What would you do with F=-kx? |
| 05:07.01 | pacman87 | um... |
| 05:07.31 | starseeker | animate it? |
| 05:07.44 | pacman87 | pass it off to libphy created in next year's gsoc? |
| 05:08.01 | starseeker | Well, you could assign a behavioral equation as an attribute |
| 05:09.23 | starseeker | has always had the knack for making the most seemingly simple little problems complex and challenging... sigh |
| 05:10.11 | pacman87 | dealing with the behavior side of it in BRL-CAD is over my head |
| 05:17.50 | brlcad | reminds starseeker of http://www.wingimp.org/tutorial/3d_maze/3dmaze.jpg |
| 05:23.08 | brlcad | starseeker: doc/IDEAS .. could implement a Kaleido primitive or a Kaleido proc-db :) |
| 05:24.13 | brlcad | not that it's any more practical, but pretty cool |
| 05:24.18 | brlcad | http://www.math.technion.ac.il/~rl/kaleido/ |

| 14:08.13 | lleroy | I posted a question on http://sourceforge.net/forum/forum.php?thread_id=2105803&forum_id=362510 a week ago, but I got no reply |
| 14:11.37 | clock_ | lleroy: once I posted a bugreport on Samba and they fixed it after a year |
| 14:12.39 | lleroy | i see... I had feedback one issue I reported 4 years ago in mozilla recently:-) |
| 14:13.48 | lleroy | thing is, it seems so basic (like it's the first entry on one of the top level menu's and it's not working in a major release) so I hoped to get feedback somewhat quicker than a year |
| 14:14.01 | clock_ | which one of the hundreds of thousands bugs they have was it? :) |
| 14:14.52 | clock_ | lleroy: what did they say? That the version for which you reported is already discontinued so it's your fault? |
| 14:15.28 | lleroy | nah, iirc they moved it to a future milestone or so :-; |
| 14:15.34 | lleroy | ;-) |
| 14:16.24 | clock_ | with software like this I think the term "trashheap" is more suitable than "milestone". |
| 14:17.42 | mafm | lleroy: depending on the client, you can see a list on some side of the window/tab/whatever showing you who's there |

| 14:50.13 | pacman87 | i had that commit typed in last night, and apparently never hit enter... |

| 14:50.40 | lleroy | and I wonder if this is a "yeah, we know about it" bug or a "that should normally work" bug |
| 14:50.47 | mafm | pacman87: sounds like lazy evaluation... |
| 14:51.01 | lleroy | db_lookup(-n) failed: -n does not exist |
| 14:51.36 | pacman87 | mafm: i got distracted by more coding, and went to bed without looking back at that console tab |
| 14:52.20 | mafm | lleroy: what do you mean with "and I wonder if _this_ is a...", I cannot see any comment to that bug |
| 14:53.01 | lleroy | I mean... does this work in the released version, or is this broken ? |
| 14:53.03 | mafm | pacman87: so you only "evaluated" it just when you needed it commited, I guess ;) |
| 14:53.20 | lleroy | just to know if it's broken due to my compiling it or if it's in the release |
| 14:53.45 | pacman87 | i need a better process scheduler - shouldnt' have to wait all night to get processor time ;) |
| 14:53.56 | mafm | lleroy: well, the three guys that are babling actively in the channel (except for clock_) are newcomers to the project, afaik |
| 14:54.18 | mafm | and I only fired mged a couple of times, so I can't really confirm or deny.. |
| 14:54.46 | mafm | you'll probably have to wait around until some experienced devel appears |
| 14:55.37 | mafm | pacman87: you're thinking about overclocking yourself with coke, or what?! :) |
| 14:55.38 | lleroy | mafm: ok thanks. It worked on 7.10.2 for windows... so I want to know if I did something wrong during compiling on slackware... |
| 14:56.04 | pacman87 | no, i just need to renice 'sleep' to a lower priority |

| 14:56.29 | mafm | lleroy: did you have some special compilation warnings? |
| 14:56.33 | mafm | homovulgaris o/ |
| 14:56.53 | homovulgaris | hi all .. phew.. long time.. |
| 14:57.14 | homovulgaris | mafm: did u see my 200 minute build screenshot :( |
| 14:57.20 | mafm | pacman87: well, Linus sleeps 9+ hours per day, apparently; brlcad about 4 or less... your mileage may vary :D |
| 14:57.29 | lleroy | mafm: it didn't exactly check each warning during compilation, to be honest... |
| 14:58.52 | mafm | lleroy: if you have the source around, maybe you can try to compile with "make -s", so it leaves only prominent warnings and not the whole compiler command line |
| 14:59.02 | homovulgaris | pacman87: seems like revolve is making good progress :) hows the sketch editor wishlist going :) ? |
| 14:59.03 | mafm | so errors and warnings are easier to spot |
| 14:59.21 | mafm | homovulgaris: you mean the mail about g3d? I did, yes |
| 14:59.35 | lleroy | mafm: ok, will try tomorrow. unfortunately i cannot be around on irc when the developers are on |
| 15:00.06 | homovulgaris | mafm: naah not the rt^3 build. brlcad build on my p3 took 197 minutes :P |
| 15:00.15 | mafm | lleroy: also you can try to write to brlcad-devel mailing list, it's probably the best place for things like this |
| 15:00.37 | homovulgaris | http://parametrics.files.wordpress.com/2008/07/screenshot-deos-wrk-brlcad.png |

| 15:01.00 | *** part/#brlcad lleroy (n=chatzill@axsguard.bepco.com) | |
| 15:01.54 | homovulgaris | mafm: i'd experiment with rt^3 when i get my laptop hard disk fixed or when my desktop crosses the flood somehow :P |
| 15:02.45 | mafm | why is it so slow? |
| 15:02.47 | homovulgaris | mafm: I had a few ideas about constraint representation in the new gui.. but that is pretty far away.. I need to finish a minimal system first :P |
| 15:03.38 | mafm | yes, I have quite a few things to do myself... :) |
| 15:05.39 | pacman87 | d_rossberg: for closing an open sketch, right now i just have all open endpoints connecting directly to the y axis, instead of trying to string multiple open segments together. i think this will be more consistant, as all of the added lines can be clearly differentiated from the original sketch. |
| 15:06.07 | homovulgaris | check out Spirit sometime .. EBNF parser generator library.. almost even looks like BNF grammar :) http://www.boost.org/doc/libs/1_35_0/libs/spirit/doc/introduction.html |
| 15:07.50 | mafm | homovulgaris: why is the compilation so slow? |
| 15:10.33 | homovulgaris | 7 year old computer and processor with 128 MB ram :| |
| 15:11.00 | mafm | seesh |
| 15:11.34 | mafm | might the access to a remote machine help you? |
| 15:12.08 | homovulgaris | :) with brlcad on it ? |
| 15:12.38 | mafm | I don't know if you can perform your work remotely |
| 15:12.54 | mafm | and if the lag would be a problem |
| 15:12.59 | pacman87 | distcc? |
| 15:13.25 | homovulgaris | naah.. i mean it is not that bad.. just the whole system build takes a long time.. as long as i have to do a make clean things are ok i guess |
| 15:13.53 | mafm | but probably someone around (even me if there's nobody else with better chances) can offer you access to a better machine than that one |
| 15:14.16 | homovulgaris | grrr.. I love my first computer :D |
| 15:15.02 | mafm | what's the problem with the floods anyway? |
| 15:15.16 | d_rossberg | pacman87: that's ok, automatically closing the loop will probable produce a result the user doesn't want |
| 15:15.19 | mafm | did you have to move because of them or something? |
| 15:15.39 | homovulgaris | desktop in college stuck with the courier service :D |
| 15:15.39 | d_rossberg | therefore it isn't important how it looks like as long as it is consistant |
| 15:15.54 | pacman87 | ok, that's what i thought; just making sure |
| 15:16.17 | d_rossberg | the result should help the user finding the errors |
| 15:16.37 | homovulgaris | hmm.. k .. me going back to writing grammar and finishing the parser :) |
| 15:16.50 | mafm | I see |
| 15:18.53 | d_rossberg | pacman87: your method can produce intersection in the closed loop you have to handle |
| 15:19.37 | pacman87 | hmm? |
| 15:23.47 | pacman87 | d_rossberg: intersections how? |
| 15:25.27 | homovulgaris | brlcad: when passing information from C to C++ : specifically rt_*_params to pcParser.h objects, one method is to pass them as data structures : the existing unions, pointers and so on ( example pval.vectorp ) . Since I am writing a parser for constraint expressions anyways, should i consider transfering variable/parameter information to pcParser.h via pc_pc_set as parseable text ? |
| 15:27.22 | homovulgaris | brlcad: for example, something like "@Radius#2.3#4.2#2.8" .. which is better precision wise .. conversion and passing as string or passing on a fastf_t/double as such ? and which one whould i use ? |
| 15:28.26 | d_rossberg | pacman87: look at the example i send you by mail, if you connect the end point of the first line with the y-axis this connection line will intersect the second line of the sketch |
| 15:31.28 | pacman87 | then the area to the left of the line (1,1.5); (1.5,2) will be open |

| 15:33.39 | d_rossberg | if you see the intersection and handle it it's ok |
| 15:33.55 | homovulgaris | starseeker: did u think about making the industry and overview diagrams maintainable via xml ? |
| 15:34.15 | pacman87 | d_rossberg: why does it need to be handled seperately? |
| 15:34.46 | pacman87 | are you saying the hollow area is bad? |
| 15:35.08 | d_rossberg | not seperately, but you have an implicite line on the y-axis which connects the two closing lines |
