Use section custom value in a header text.
by Pawel Urbanski 22 Dec '22

22 Dec '22

Dear Friends, I spent some time searching and coding simple documents, but failed and therefore I'm asking for help... A section such as chapter cn have custom keys with values. One uses the: \structureuservariable command to access such values. How can I use such a value to create a custom header in a format: Prefix: \structureuservariable{foo} I am asking for the only thing that worked when I tried was calling the: \setupheadertexts command inside a chapter environment block with some prefix. Unfortunately the value from the custom field was not expanded. It was correctly inserted in a regular paragraph. For example: \startchapter [title={A sample title}][custom_something={random_value}] ... \stopchapter How can I put the value of: custom_something in the header with some prefix? All the best and thanks, Pawel

upload

Hi, I uploaded a new version of lmtx. This version uses a new counter and dimension model deep down (\newinteger and \newdimension) which is more efficient in certain cases. From the user's perspective there is no difference between \newcount and \newdimen although there are some fundamental differences. I might have overlooked a few cases where it does make a difference in ConTeXt (easy to handle once I know). The test suite runs 5-10 % faster depending on the load of the machine and the gain mostly relates to memory access (where processes fight over memory and cpu cache). Of course I can probably gain more but using a faster machien than this 5 year old one but why waste a good machine. Some other possible speedups are on-hold till I have better test cases.

Mathematical MetaFun Mania
by Gavin 21 Dec '22

21 Dec '22

Hello MetaFun Math Lovers, I am using MetaFun to attach diagrams to formulas. Both the physics and the typesetting are going great! I attached a sample below, to give a taste of what I am trying to do. This page of actual calculations has examples of almost everything I need. It’s a lot, but it is all working. Right now the interface is terrible, but effective. Thanks to Hans and Mikael for many helpful hints! I am still using \hpos and \setMPpositiongraphic, because I haven't figured out how to pass information from \mathboxanchored and \connectboxanchors to my MetaPost code. Here is the code for the connectors: \startMPpositiongraphic{mypos:contract} path pa, pb, pab ; numeric na, nb ; string ta, tb, hand, product ; ta := mpvars("from") ; tb := mpvars("to") ; stemshiftfrom := (EmWidth/8)*mpvarn("startstem") ; stemshiftto := (EmWidth/8)*mpvarn("stopstem") ; hand := mpvars("hand") ; product := mpvars("product") ; delta := mpvard("distance") ; na := positionpage(ta) ; % page number of a nb := positionpage(tb) ; % page number of b pa := positionbox(ta) ; % box of a pb := positionbox(tb) ; % box of b if hand = "right" : z1 = 0.5[llcorner pa,lrcorner pa] shifted (stemshiftfrom, -ExHeight/4) ; z2 = 0.5[llcorner pb,lrcorner pb] shifted (stemshiftto, -ExHeight/4) ; y3 = min(y1,y2) - ExHeight/2 -delta; else : z1 = 0.5[ulcorner pa,urcorner pa] shifted (stemshiftfrom, ExHeight/4) ; z2 = 0.5[ulcorner pb,urcorner pb] shifted (stemshiftto, ExHeight/4) ; y3 = max(y1,y2) + ExHeight/2 +delta; fi ; if na = nb : % Check that positions are on the same page pickup pencircle scaled 0.6pt ; if product = "sym" : draw z1 -- (x1,y3+ExHeight/2) ; draw z2 -- (x2,y3+ExHeight/2) ; pickup pencircle scaled 1.2pt ; draw (x1-EmWidth/8,y3) -- (x2+EmWidth/8,y3) ; else : pab := z1 -- (x1,y3) -- (x2,y3) -- z2{down} ; draw pab ; fi ; positioninregion ; fi ; \stopMPpositiongraphic A connector command might look something like this: \setMPpositiongraphic{X-1}{mypos:contract}{to=X-2,product=sym,startstem=-2,stopstem=2,distance=0.5ex} All of the key=value pairs in the last argument of \setMPpositiongraphic pop right up in my MetaPost code with mpvar(“key”). I haven’t been able to follow this with \mathboxanchored and \connectboxanchors. My two questions are: 1) Can I use \setMPpositiongraphic with \mathboxanchored? That would allow me to go straight to my MetaPost code without the \connectboxanchors interface 2) Can I tell \connectboxanchors to use my MetaPost code and pass key=value pairs like I do with \setMPpositiongraphic? Thanks for any hints! Gavin

OT: Adobe releases the original PostScript interpreter software as open source
by Bruce Horrocks 19 Dec '22

A bit off topic but some might be interested... Adobe have released the PostScript interpreter source code as open source. Press release here <https://www.globenewswire.com/news-release/2022/12/01/2566212/28639/en/Comp…> and a blog post with the background to PostScript here <https://computerhistory.org/blog/postscript-a-digital-printing-press/> Regards, — Bruce Horrocks Hampshire, UK

Command line arguments on context project
by Jethro Djan 19 Dec '22

19 Dec '22

Dear list, I am using the project structure to typeset my thesis. This is how the directory looks like: chapters/chapter1.tex chapters/chapter2.tex … output/ env_thesis.tex prd_main.tex ref.bib I didn’t use the project. 1. How do I specify output directory? I have already seen the following thread: https://www.mail-archive.com/ntg-context@ntg.nl/msg101654.html <https://www.mail-archive.com/ntg-context@ntg.nl/msg101654.html> It doesn’t seem to work on a project. So for example when I run mtxrun —path=output --script context ../prd_main, I get this error: tex error on line 5 in file /usr/local/texlive/2022/texmf-dist/doc/latex/buctthesis/chapter1.tex: ! Undefined control sequence 2. How do I get CoTeXt to recognise the ref.bib file when I run the components not the product? For context, I don’t want the references printed at the end of each chapter but I would like the in-text citation to work (if that is possible). If not, is it possible compile the whole product but only output a certain page range? Jethro

bottlenecks
by Hans Hagen 18 Dec '22

18 Dec '22

Hi, I'm (occasionally) trying to 'minimize' bottlenecks in the context / luametatex code. This is kind of hard because both are rather efficient already. On regular runs performance is probably okay but there are cases when one has a large complex document (e.g. with many tables) or has many runs (e.g. thousands of documents in one go). In that case even minor speedups can accumulate and become measurable (esp on vms and runs over a network). It can safe time and also energy (which can matter todays KWh pricing). So the challenge is how to determine bottlenecks. Are there users on this list that have document runs of more than 10 seconds (as reference: the luametatex manual takes < 9 seconds for 350 pages and loads plenty fonts and has many tables) or have many (small) runs and are annoyed by the runtime? And if so, what does one guess are the bottlenecks? Hans ps. Much runtime is spent in Lua and there is not that much we can do about making that faster. ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
