Some very simple cld - loading a module
by Hamid,Idris 18 Aug '23

18 Aug '23

Dear gang, The following, simple MWE gives an undefined control sequence error: ======= % \usemodule[translate] % \enableinputtranslation \startluacode -- context.usemodule({translate}) context.usemodule{translate} context.enableinputtranslation() context.darkgreen() \stopluacode \startTEXpage[offset=1em] \translateinput[Hermes][Idris] Hermes \disableinputtranslation Hermes \stopTEXpage ======= tex error > tex error on line 14 in file ./test-luacode.tex: Undefined control sequence <line 3.12> \translateinput [Hermes][Idris] ======= The reason for the error is that the module is not being loaded. Toggling back to context syntax, of course, works. Reference: ConTeXt Lua Documents by Hans Hagen, page 22. The following analogous code works: \startluacode context.startchapter{first} \stopluacode So how do we properly load the module from within a luacode environment? Thank you in advance.

Table head/body via lua
by Alexey Kryukov 18 Aug '23

18 Aug '23

Hi, I am trying to generate a table representation for some xml source. As the data structure doesn't directly correspond to the desired table structure, some manipulations via lua are required. So far everything works OK except table sectioning commands, like \bTABLEhead, \eTABLEhead, bTABLEbody or \eTABLEbody: it seems impossible to incapsulate them into lua functions. For example, the following is not compiled: \starttext \bTABLE \ctxlua{context.bTABLEbody()} \bTR \bTD Cell 1\eTD \bTD Cell 2\eTD \eTR \ctxlua{context.eTABLEbody()} \eTABLE \stoptext Can anybody suggest a workaround (except changing the source XML of course)? -- Regards, Alexey Kryukov <anagnost at yandex dot ru> Moscow State University Faculty of History

I was using an old LMTX copy, and that was the issue. Thanks to Hans for pointing that out. Now I'm trying to expand my solution a little more. Is there any way to retrieve an element in a dataset by using the key? For example, given an "authors" dataset, I would like to do something similar to: %% Given this data structure ... \setdataset[authors][ nombre={Andrés Conrado Montoya Acosta}, bio={This is a bio, it could be two or three paragraphs long}, email={loremipsum(a)email.edu.co}, cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… }, orcid={https://orcid.org/0009-0007-0765-4241}, gscholar={ https://scholar.google.com/citations?user=GpYTTU0AAAAJ&hl=es&authuser=1}, ] %% I want to do something like.... \startGetAuthor[nombre={Andrés Conrado Montoya Acosta}] \datasetentry{bio}\par email: \mailhref{\datasetentry{email}} \stopGetAuthor So, if my name is found in the dataset, get the data for that name. Is something like that possible?

Thank you Hanks, seems to work well after some tweaking. I had an issue, the patch you sent me gave an error when I ran 'context --make'. The error said: tex error > tex error on line 51 in file core-dat.mkxl: Parameters must be numbered consecutively [#1]#*[ <to be read again> S <line 3.51> \permanent\tolerant\protected\def\setdataset[#1]#*[#S #2]#*[#S#3]% <empty file> I've inserted the digit you should have used after the #. I edited line 51 as: \permanent\tolerant\protected\def\setdataset[#1]#*[#2]#*[#3]% Instead of your original: \permanent\tolerant\protected\def\setdataset[#1]#*[#S#2]#*[#S#3]% And now context --make runs, and the example compiles correctly, however, not really sure if what I did was the right thing to do.

new upload
by Hans Hagen 17 Aug '23

17 Aug '23

Hi, I uploaded a new lmtx (some new - experimental - things will be explained after the ctx meeting), but there's one thing that is somewhat important. In addition to the built in units we can now have so called user units. There is some more info about this in the lowlevel-registers manual. One of the predefined units is 'uu' with an associated \ununit (dimension) variable and it's is also interfaced to metafun. That means that when you use uu in metapost graphics you have to make sure that you save the meaning and/or numeric uu now. The idea is that just as in mp one can say 20xx with xx being a (sort of) unit, one can do the same in tex. Think of \newdimension \MyUnitA \MyUnitA 1.23pt \pushoverloadmode % just in case \newuserunit\MyUnitA ua % binds the unit to the variable \popoverloadmode x\hskip 10ua\relax x The units starting with 'u' are considered user units but be carefulk with other combinations as we have (and will have more) built into context ones, like pi : pi for Mikael ft : foot for Alan fs : (global body) font size tw : (layout) text width th : (layout) text height hs : (current) hsize vs : (current) vsize cd : (when set) column distance cw : (when set) column width cx : combination cell width uu : user unit (\METAFUN) So Mikael can now have test \hskip 3pi\relax test and Alan can have \setuplayout [width=1ft] to be consistent with inches. The reason why we have this mechanism is that it provides a level of abstraction. It might evolve over time but don't expect the 600+ units possible to show up because one needs sensible shortcuts. Already built in unit always win and you cna only bind to already defined quantities. Here's one for those who want to go beyond the normal: \newdimension \FooA \FooA 1.23pt \newdimen \FooB \FooB 12.3pt \protected\def\FooC {\the\dimexpr\FooA +\FooB\relax} So you can now figure how 'cx' is defined in a dynamic way.

Optical scaling in Latin Modern
by Hamid,Idris 17 Aug '23

17 Aug '23

Dear gang, It seems that ConTeXt does not currently implement optical scaling for Latin Modern -- at least not by default. For example: ======= \startTEXpage[offset=1em] Test {\tfa Test} {\tfb Test} {\tfc Test} {\tfd Test} {\tfx Test} {\tfxx Test} \stopTEXpage ======= In the log we have ======= mkiv lua stats > loaded fonts: 2 files: latinmodern-math.otf, lmroman10-regular.otf ======= Is this behavior intentional? The needed sizes are certainly available (/texmf/fonts/data/gust/lm). This issue came up while trying to test/implement something else. Although Computer Modern / Latin Modern is perhaps hardly popular for contemporary publication work, a full implementation of the full palette of optical sizes is still useful as a benchmark, etc. Best wishes Idris -- Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523

Experiments with \doloopoverlist
by Andres Conrado Montoya 17 Aug '23

17 Aug '23

Hello List. I've been trying to typeset a somewhat complex list of authors for several articles and a book. My proof of concept seems to work fine, however, I know I am doing weird things that I think could probably be done in a better way. I'm using datasets and a recursion, kind of hacky but I can't find a better way of handling it. Specifically I would like to know: 1. Is there a way of getting the length of a filled dataset? (how many entries it contains) 2. Is it OK to use \startuserdata \stopuserdata without its inlineuserdata? Is there an alternative that does not require inlineuserdata? %%%%%%%%%% MWE: \setupinteraction[state=start] \define[2]\imghref{\bgroup\goto{#1}[url(#2)]\egroup} \defineexternalfigure[logo][height=1em] \definedataset[autores] \setdataset[autores][ nombre={Angie Natalia Farfán Acevedo}, cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… }, orcid={https://orcid.org/0009-0007-0765-4241}, gscholar={ https://scholar.google.com/citations?user=GpYTTU0AAAAJ&hl=es&authuser=1}, ] \setdataset[autores][ nombre={Ivon Andrea Rodríguez Román} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0001-1183-6829} gscholar={https://scholar.google.com/citations?user=iz8SQNcAAAAJ&hl=es} ] \setdataset[autores][ nombre={Angie Caterin Garzón González} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0009-0990-6902} gscholar={ https://scholar.google.com/citations?view_op=list_works&hl=es&user=5WqcOeEA… } ] \setdataset[autores][ nombre={Heidy Paola Veira Tenorio} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0008-4076-7317} gscholar={ https://scholar.google.es/citations?view_op=new_profile&hl=es&authuser=1} ] \setdataset[autores][ nombre={Yerly Lorena Diaz Aldana} cvlac={ https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do… } orcid={https://orcid.org/0009-0008-1720-4057} gscholar={ https://scholar.google.com/citations?hl=es&user=0obyCwkAAAAJ&view_op=list_w… } ] \defineuserdataalternative[idautor][renderingsetup=userdata:idautor] \startsetups[userdata:idautor] \dontleavehmode \imghref {\externalfigure[cvlac.pdf][logo]} {\userdataparameter{cvlac}} \quad \imghref {\externalfigure[orcid.pdf][logo]} {\userdataparameter{orcid}} \quad \imghref {\externalfigure[gscholar.pdf][logo]} {\userdataparameter{gscholar}} \quad \userdataparameter{author}\par \stopsetups \defineuserdata[idautor][alternative=idautor] \startdocument % I have to manually set the length of the dataset in the loop and use recurselevel... % Maybe there is a way to use the length of the "autores" dataset? and use indexes? \dorecurse{5}{ \startuserdata[idautor][ author={\datasetvariable{autores}{\recurselevel}{nombre}}, cvlac={\datasetvariable{autores}{\recurselevel}{cvlac}}, orcid={\datasetvariable{autores}{\recurselevel}{orcid}}, gscholar={\datasetvariable{autores}{\recurselevel}{gscholar}}, ]\stopuserdata % My "inlineuserdata" is empty... no idea if this is OK... } \stopdocument %%%%%%%%%% END MWE Thank you in advance. -- Andrés Conrado Montoya Andi Kú andresconrado(a)gmail.com http://sesentaycuatro.com http://messier87.com http://chiquitico.org ---------------------------------------- Los fines no justifican los medios, porque la medida verdadera de nuestro carácter está dada por los medios que estamos dispuestos a utilizar, no por los fines que proclamamos. ---------------------------------------- “You develop an instant global consciousness, a people orientation, an intense dissatisfaction with the state of the world, and a compulsion to do something about it.
