03:51.52brlcadGurwinder: yes, it's giving angles for the three vectors that define the ell
03:52.19brlcadyou really should be using the A B C vectors though, not the angles, as they contain the magnitude/length information
03:53.16brlcadhere's an example you can try:
03:53.20brlcadmake ell ell
03:53.23brlcadl ell

03:56.21brlcadnotice how the values all change (except V)
03:56.54brlcadthe ell was actually "morphed" since we were doing a solid edit, it wasn't just rotated
03:57.43brlcadbasically, it's a different shape now

04:05.09GurwinderI was trying to rotate ellipse using magnitude but I not write way. I have to find a way to read rotaion angles of A, B, C
04:07.27Gurwindersorry for wrong words, magnitude is not a right way to rotate, I have to use those direction cosines/rotation angles of A,B,C for ellipse rotation

15:43.05sofatbrlcad, I have solve the problem now my stylesheet is working with building system. I made new macro (DOCBOOK_TO_PHP) in mise/cmake/DocBook.cmake. I have  copied the all code of DOCBOOK_TO_HTML macro into DOCBOOK_TO_PHP and then change the extension of output file html to php and change surffix from _html to _php. After that I add new variable for new stylesheet(my wordpress xsl stylesheet) variable name is XSL_PHP_STYLESHEET.
15:43.46sofatAfter this I edit doc/docbook/CMakelist.txt add the definitions about DOCBOOK_TO_PHP, also add the definition about stylesheet in this file doc/docbook/article/CMakeList.txt file
15:44.00sofatAfter this add the DOCBOOK_TO_PHP command in doc/docbook/article/en/CMakeList.txt file.
15:44.43sofatthen i run ./configure command and i see in this doc/docbook/article/en/ directory two cmake files first for html(filename_html.cmake) and other for php(filename_php.cmake)
15:46.35sofatthen i run make command  and I see all xml document converted into wordpres php structure and placed into share/doc/html/article/en/
15:51.38brlcadsofat: YAY!  that's great!
15:51.54brlcadglad you were able to figure it out ... now submit that all as a patch ;)
15:52.05brlcadmake sure you don't miss any files you added (svn add)
15:52.37sofatthanks
15:52.38sofati will do this
15:52.39brlcadstarseek1r: this looks interesting: https://github.com/Dead2/zlib-ng
15:53.14brlcadsofat: that really is great, nice work
15:55.09sofatyes i only apply this on articles/en documents
15:55.11sofati will apply on all document then i submit this settings as patch
15:55.11sofatthanks so now my first milestone is completed  ?
16:10.11brlcadsofat: definitely a notable accomplishment, next will be to get server account set up so you can write a script that publishes them
16:11.36sofatok i know this is my next milestone of this week.
16:14.29sofatbrlcad, i found toc.xml file. you allow me to update this ? because i think if i add the new menu details in this file then its able to work as sidebar menu for website (table of content page).
16:16.24sofatas well as main page also

16:51.42bradhstarseek1r: you may want to look at my dev logs, to see where i am in relation to the schedule. i have a few questions about cmd line parameter passing for models, etc.

17:31.33andrei_starseek1r: hi !
17:31.36starseek1randrei_: howdy
17:31.50andrei_I've been trying to help andrei_il (Andrei Ilinca) with the parser
17:31.57andrei_like, explain how a parser works
17:31.59andrei_what it does
17:32.00starseek1ris this the re2c/lemon work?
17:32.02andrei_yeah
17:32.17andrei_I believe he got the right idea
17:32.20andrei_about the csg grammar
17:32.24*** join/#brlcad ih8sum3r (~chatzilla@122.173.204.25)
17:32.31starseek1rexcellent - thanks for your help!  I've seen the patch, but haven't had time to look at it yet
17:32.34andrei_but his lemon parser generates an empty file which is rejected by gcc linker
17:32.53starseek1ris that his specific lemon input or any lemon input?
17:33.01andrei_he took the dom2dox
17:33.03andrei_and stripped it down
17:33.15starseek1rhmm
17:33.17andrei_then applied a simple grammar
17:33.27starseek1ris that the patch he submitted to the list?
17:33.28andrei_like, it should've gone through one group() { }
17:33.32andrei_yes
17:33.49andrei_I suspect that the empty file is generated due to a bad grammar
17:33.50starseek1rOK.  If it's generating a completely empty file, it's probably just missing some aspect of the lemon setup
17:33.59starseek1ror yeah, invalid grammar
17:34.15starseek1rbest approach there is to get something absurdly simple working
17:34.25starseek1rthen gradually increase the complexity of the grammar
17:34.33andrei_I used antlr each time, so I have a bit of fight figuring lemon
17:35.00andrei_yeah,  you just gave me an idea
17:35.04andrei_his main issue is that
17:35.08andrei_he doesn't have how/what to debug
17:35.15andrei_b/c the issue is in the generated files
17:35.17andrei_not in lemon
17:35.20starseek1rheh - not surprising.  re2c/lemon is an unusual combination.  It checked the boxes of portable to windows, fast, minimal deps, and easy to build
17:35.33andrei_sorry, compiler error, not issue
17:36.41starseek1rbut most folks are willing to generate code and check it in, so those factors don't really enter into it.  We don't (generally) check in code unless it's a bootstrap situation
17:36.46``Erikif only windows behaved, there'd be so many other options :)
17:36.58andrei_haha, ``Erik
17:37.04starseek1randrei_: right - it's unlikely to be lemon's fault
17:37.34andrei_I suspect that he'll also have to plug in another .c file soon, like a "main"
17:37.52starseek1rand the compiler errors won't be tremendously helpful at this stage - he needs to get a feel for what a "correct" grammar definition looks like
17:37.55andrei_to handle how the AST is saved in our geometry
17:38.28starseek1randrei_: are you aware of the files in doc/parsers ?
17:38.32starseek1rthey may help a bit
17:38.40andrei_yeah, I've watched his progress quite a bit
17:38.54andrei_initially, he reached out asking what a grammar is, and I've sort of tried to explain from there
17:39.10andrei_if it's a grammar issue, I believe I can handle
17:39.20starseek1rthere's more available on lex/yacc and flex/bison - they may be better starting points
17:39.41starseek1rI believe most of our re2c/lemon code is actually "ported over" flex/bison inputs
17:39.43andrei_afaik flex/bison is a lot more complicated
17:39.48andrei_but I did wrote some turing machine parser in that ..
17:40.20starseek1randrei_: right - I just ment if he needs some documentation to follow to get the hang of how it works
17:40.37starseek1rI'd have a fair bit of spin-up time on such systems myself - n_reed is our real expert
17:40.50andrei_ah.
17:41.15andrei_I'll do my best to look and help him but, whenever you got time, you probably have to look over his e-mail
17:41.21starseek1rbradh: I'll look over your dev logs - if we can't get a meet-up on IRC this week, please post your questions to the mailing list and I'll try to respond there
17:41.55starseek1randrei_: I intended to look over his posted patch - I've not had time to do much of anything this week, so apologies for the delay
17:42.05starseek1rI'll try to get it this weekend
17:42.17andrei_no worries, I know mentors are swamped during GSoC. Caused that myself :)
17:43.33bradhstarseek1r: sounds good. i'll be sure to do that.
17:44.36starseek1rbradh: is the nmg data structure making sense (at least, inasmuch as it ever makes sense?)
17:46.04starseek1rdives back into the tornado... bbl
17:48.33bradhstarseek1r: still reading  about it, but for now i think my level of understanding is sufficient. i'd like to get my hands on the  original paper. but i think much of my work  will be at the API level.

17:58.53ih8sum3rHello, brlcad
18:00.24brlcadhi ih8sum3r
18:00.48ih8sum3rbrlcad: How are you
18:05.18ih8sum3rbrlcad: We need write access on the official BRL-CAD repo. so as we can make commit in the consistent manner. Currently, shubham is pushing in his repo and I'm pushing on my repo. I think this may cause clashes or other issues. I think we should work on one repo only by creating different branches. And also we must have an experimental branch so as to check the things and then merge them.
18:06.32Shubham^ seconded
18:33.16``Erikya'll using git mirrors right now?
18:43.26Shubhamforked the repo, made branches, sending our Pull Requests for the branches
