comma as decimal separator in maths mode
by Martin Althoff 21 Sep '19

21 Sep '19

Hi ... I am outputting some numbers in maths mode that have a comma as decimal separator. I get a big space after the comma, which I can prevent by writing $1{,}5$ Is there a less awkward way of getting the comma as a "real" decimal separator? Thanks, Martin \starttext $1,5$ \math{1,5} $1{,}5$ \stoptext

Command completion in TeXShop
by Rogers, Michael K 21 Sep '19

21 Sep '19

I was looking into command completion in TeXShop (MacOS) and came across this two-year-old call for help by one of the developers (I assume) for implementing it for ConTeXt: http://macosx-tex.576846.n2.nabble.com/TeXShop-Command-Completion-ConTeXt-t… As far as I found, command completion for ConTeXt has not yet been implemented. I’m pointing this out in case someone has sufficient knowledge of ConTeXt and is interested. Alternatively, perhaps it has been done, and someone can point me in the right direction.

OpenBSD install broken
by Robert Krug 21 Sep '19

21 Sep '19

Greetings, First, thanks for all the wonderful work on context. Now, to the reason for this note. I recently tries to install context on an OpenBSD 6.5 AMD64 system, but the install failed. Thanks to some helpful emails in the archives from 2017 and 2018, I was able to get this working by editing mtxrun and mtx-update.sh. I include what I did below. Thanks again, Robert 1) Do the usual: mkdir context && cd context rsync -ptv rsync://contextgarden.net/standalone/setup/first-setup.sh . ./first-setup.sh This will silently fail, because bin/mtx-update.lua bin/mtxrun do not recognize openbsd. 2) Edit bin/mtxrun: We need to define a "good" version of resolvers.platform(t,k) At line 4049, there is a default definition. Replace it with: function resolvers.platform(t,k) local platform="openbsd6.5-amd64" os.setenv("MTX_PLATFORM",platform) os.platform=platform return platform end 3) Edit bin/mtx-update: 3a) In the table update.platforms add an entry for openbsd: ["openbsd6.5-amd64"] = "openbsd6.5-amd64", I put this at line 198, after the entries for freebsd. 3b) In the function update.synchronize() replace line 282: local platforms = states.get('platforms') or { } with: local platforms = states.get('platforms') or {"openbsd6.5-amd64" } 3c) At the very start of local function add_collection(collection,platform) line 417, add: platform = "openbsd6.5-amd64" Maybe something is broken on my system or these last two aren't really needed, but this is what I did, 4) Edit first-setup.sh: To avoid overwriting the files we just edited, comment out line 146: # rsync -rlptv rsync://contextgarden.net/minimals/setup/$platform/bin . This may interfere with future updates. 5) Install for real this time: ./first-setup.sh --modules=all 6) Finally, the setuptex script gives me an error message: megaera$ . /home/<name>/Context/tex/setuptex /bin/ksh: /home/<name>/Context/tex/setuptex[163]: ${.sh.file}": bad substitution but it is not hard to set the path correctly: PATH=$PATH\:/home/<name>/Context/tex/texmf-openbsd6.5-amd64/bin ; export PATH

Extracting a column from an array in lua
by Otared Kavian 20 Sep '19

20 Sep '19

Hi, Probably this is a silly question… In lua, I have an array named t which is determined in a piece of lua code, having (say) two columns and I want to extract for example the first column of t and call the new array tt. In Matlab, Scilab and friends, this can done by saying tt = t[:,1]. Is this possible in lua? For the moment I have something like this, but I think it is not a good approach: \starttext \startluacode t = {} -- a silly example of a matrix... for i = 1, 3 do t[i] = {} t[i]["columnOne"] = 10*i + 1 t[i]["columnTwo"] = 10*i + 2 end tt = {} for i = 1,3 do -- is it possible to avoid this ? tt[i] = t[i]["columnOne"] end \stopluacode The first column of the array \type{t} is: \ctxlua{context.print(tt," ; ")} \stoptext Many thanks for any help, Best regards: OK

odd processing error with latest standalone
by Alan Bowen 19 Sep '19

19 Sep '19

In processing a book that I have edited, there is no problem using LuaMetaTeX, Version 2.00.0, 2019.07.31 But with LuaMetaTeX, Version 2.00.0, ConTeXt ver: 2019.09.10, the process stops in a specific chapter and quits with a fatal error: tex error > tex error on line 26 in file c_12-01_Greenbaum.tex: !

Re: [NTG-context] MetaPost with Multiple Variable Sections

Dear Jeroen, If you change “pair a;” to “numeric a;” in the second MPcode, it draws a circle without error. Best regards, Dalyoung > > \placefloatright{}{ > \startMPcode > pair a; numeric a; > a := 2cm; > draw fullcircle scaled (2*a); > \stopMPcode} > > \stoptext >

MetaPost with Multiple Variable Sections
by Jeroen 18 Sep '19

18 Sep '19

I have been working with MetaPost as following, which worked fine with one startMPcode section with variables, but with 2 startMPcode Metapost sections, it keeps telling me the numbers dont add up: \definefloat [floatright][figure] \setupfloat [floatright][default={right,none}] \setuplayout [backspace=20mm,width=170mm,topspace=20mm,height=250mm] \starttext \placefloatright{}{ \startMPcode pair a, b; a := (0,0); b := (50,50); draw a -- b; \stopMPcode} \placefloatright{}{ \startMPcode pair a; a := 2cm; draw fullcircle scaled (2*a); \stopMPcode} \stoptext I also have tried with the startbuffer combination as below, but this gave the same error codes. Is there any other way of working with multiple MetaPost sections with variables in a single document? \definefloat [floatright][figure] \setupfloat [floatright][default={right,none}] \setuplayout [backspace=20mm,width=170mm,topspace=20mm,height=250mm] \starttext \startbuffer \startMPcode pair a, b; a := (0,0); b := (50,50); draw a -- b; \stopMPcode \stopbuffer \floatright{}{\getbuffer} \startbuffer \startMPcode pair a; a := 2cm; draw fullcircle scaled (2*a); \stopMPcode \stopbuffer \floatright{}{\getbuffer} \stoptext

A PDF with the wrong sorting order doesn't help when you can't show a working minimal example to reproduce the problem. When you need more control about the sorting order of the index you should switch to MkIV which has more options. Wolfgang

Biblatex \crossref equivalent in bibliographies
by Damien Thiriet 15 Sep '19

15 Sep '19

Hi, With biblatex I was using crossref to shorten my .bib files, as can be seen in this MWE @periodical{DebatMem2002, title = {Le Débat}, number = {122}, langid = {french}, date = {2002} } @article{ChartiersurRicoeur2002, author = {Roger Chartier}, title = {Le passé au présent}, crossref = {DebatMem2002}, pages = {4--11} } Which keys should I use to achieve the same under ConTeXt? I found xcrossref and percentcrossref keys "Bibliographies. The ConTeXt way" but could'nt figure out how to use them. Here is my ConTeXt MWE as a starting point \language [fr] \startbuffer [bib] @periodical{DebatMem2002, title = {Le Débat}, number = {122}, langid = {french}, date = {2002} } @article{ChartiersurRicoeur2002, author = {Roger Chartier}, title = {Le passé au présent}, xcrossref = {DebatMem2002}, %does not work the way I would expect pages = {4--11} } \stopbuffer \usebtxdataset[bib.buffer] \usebtxdefinitions[apa] \definebtxrendering [example][apa] \starttext \nocite[ChartiersurRicoeur2002] \placelistofpublications \stoptext Thanks, Damien Thiriet
