05:54 <J23k23> why is this 2 ?  a=0;echo(5 + a?2:1);  // i know that it is working with brackets but what is going on that it is 2 independent from a and the 5 is also ignored

07:09 <Scopeuk> I guess it proccessed 5+a before the turnary

07:10 <Scopeuk> It is odd. I don't know their precedence in scad

08:36 <J23k23> Scopeuk ah you are totally right   it is checking (5+a)?  .. .  a=5; echo(5 - a?2:1);  // gets 1

08:36 <J23k23> thanks!

08:41 <J23k23> bit confusing as  5-a%2  is not (5-a)%2

10:06 <Scopeuk> yeh I guess ? gets a weird precedence

16:10 <Guest76877689> Hello, I like the idea of parametric modeling, but the OpenSCAD language seems very poor and inexpressive to me. I decided to write my analogue in Common Lisp. Could you tell us about the architecture of your program? What are its main parts? What libraries did you use and would it be difficult for me to write them myself? I am going to implement

16:10 <Guest76877689> my program in the form of a Lisp library.

16:12 <teepee> writing something is not that difficult, maintaining it for users is

16:14 <teepee> also openscad != just the language - as will be shown soon-ish by also having python support

16:19 <Guest76877689> What are the main difficulties that may arise with support?

16:22 <teepee> time

16:25 <Guest76877689> What exactly needs to be supported? Will features need to be added? Is it possible to solve most of the problems by adding a plugin system, like EMACS?

16:27 <teepee> *needs*? no idea, everyone has different ideas and wishes. and that's why it's often good to have alternative solutions, like GUI CAD or Code CAD

16:28 <teepee> also not just features, not all users can or want to build stuff, so maintaining builds to just install on ideally all main platforms is quite useful

16:30 <Scopeuk> even just maintain executables for compatibility with Mac/Windows/Linux is quite time consuming without continuing development

16:30 <teepee> incidentally the language topic came up recently on the mailing list, so relevant post: https://lists.openscad.org/empathy/thread/NXJ5ZHJHLGC6AM4I2O4H5XWBG6D2VWDY?hash=EF4I35QQ5J3CJCBJBOONT646JXJ5JFTD#EF4I35QQ5J3CJCBJBOONT646JXJ5JFTD :)

17:10 <Guest76877689> Tell me, how long will it take to write a library that would have the same capabilities as OpenSCAD, but without a graphical interface?

17:12 <teepee> no idea. *all* the stuff running on all platforms probably quite a long time, years. something limited but usable might be possible in a couple of weeks

17:13 <teepee> I suggest to still ask the question, what happens after that

17:14 <teepee> I've seen lots of projects with a flurry of activity for some month and then die and gather dust on github

18:15 <Av8r> ImplicitCad has a Haskell API (in addition to implementing the OpenSCAD language).  You might start there.

23:21 <juri_> Av8r: I exist! :)
