Status of Asymptote
by Alexandre Christe 11 Jan '24

11 Jan '24

Dear all, I'd like to know what is the status of Asymptote in Context. To my knowledge, metapost/metafun only support 2D (except with the additional libraries from Roegel, which would have to be cleaned up a bit). Otherwise, what shall be used for 3D drawings in Context? TikZ? Something else? Thanks in advance. Alex

Firefox doesn't show the "yes", nor Acrobat X, but SumatraPDF does. I modified your definition as: \definefield[test][check][cbox][][] And now the "yes" doesn't appear. However, I don't know how this affects the functionality of the form. -- 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.

Non-standard font alternatives
by Matthew McCabe 20 Apr '23

20 Apr '23

Hi list, I'm looking to import a font with medium and light weights (in this case Roboto) and define font alternatives so one can quickly switch to light text just as one would switch to bold text. There is a stackexchange answer from Wolfgang (https://tex.stackexchange.com/questions/303648/context-font-weights) which details a solution to this problem for ConTeXt MkIV but despite my best efforts I haven't been able to get things to work for me. There is the Roboto typescript example on ConTeXt garden but it isn't exactly what I'm looking for as for the document I'm making I would prefer to be able to treat the font weights as alternatives rather than separate families since I will be switching often. One can download the exact set of fonts I am using from https://fonts.google.com/specimen/Roboto Here is my code: \definefontalternative[lf] % light \definefontalternative[li] % lightitalic \definefontalternative[md] % medium \definefontalternative[mi] % mediumitalic \starttypescript [sans] [roboto] \definefontsynonym [SansLight] [file:Roboto-Light] [features=default] \definefontsynonym [SansLightItalic] [file:Roboto-LightItalic] [features=default] \definefontsynonym [Sans] [file:Roboto-Regular] [features=default] \definefontsynonym [SansItalic] [file:Roboto-Italic] [features=default] \definefontsynonym [SansMedium] [file:Roboto-Medium] [features=default] \definefontsynonym [SansMediumItalic] [file:Roboto-MediumItalic] [features=default] \definefontsynonym [SansBold] [file:Roboto-Bold] [features=default] \definefontsynonym [SansBoldItalic] [file:Roboto-BoldItalic] [features=default] \definefontsynonym [SansCaps] [file:Roboto-Sans] [features=smallcaps] \stoptypescript \starttypescript [sans] [roboto] \definebodyfont [default] [rm] [lf=SansLight sa 1, li=SansLightItalic sa 1, tf=Sans sa 1, it=SansItalic sa 1, md=SansMedium sa 1, mi=SansMediumItalic sa 1, bf=SansBold sa 1, bi=SansBoldItalic sa 1, sc=SansCaps sa 1] \stoptypescript \definetypeface[roboto][rm][sans][roboto][default] \setupbodyfont[roboto] \starttext \lf Light \li LightItalic \tf Regular \it Italic \md Medium \mi MediumItalic \bf Bold \bi BoldItalic \sc SmallCaps \stoptext - The result is entirely in the regular weight default font: What I've tried: 1. I've tried a great deal of alternative \definefontsynonym arguments such as specifying by name, including the full path to each ttf file 2. I played around with different two character \definefontalternative arguments to ensure there was no overlap with existing commands (as far as I am aware the existing set are otherwise undefined) A few things to note: 1. My current version of ConTeXt is 2022.12.09 16:34 2. For portability I have included the ttf files for Roboto in a directory within my project directory and while setting things up I set OSFONTDIR to include this directory and run `mtxrun --script fonts --reload --force` 3. `mtxrun --script fonts --list --all --pattern=Robo` yields: identifier familyname fontname filename subfont instances roboto roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoblack roboto robotoblack ./fonts/Roboto/Roboto-Black.ttf robotoblackitalic roboto robotoblackitalic ./fonts/Roboto/Roboto-BlackItalic.ttf robotobold roboto robotobold ./fonts/Roboto/Roboto-Bold.ttf robotobolditalic roboto robotobolditalic ./fonts/Roboto/Roboto-BoldItalic.ttf robotoitalic roboto robotoitalic ./fonts/Roboto/Roboto-Italic.ttf robotolight roboto robotolight ./fonts/Roboto/Roboto-Light.ttf robotolightitalic roboto robotolightitalic ./fonts/Roboto/Roboto-LightItalic.ttf robotomedium roboto robotomedium ./fonts/Roboto/Roboto-Medium.ttf robotomediumitalic roboto robotomediumitalic ./fonts/Roboto/Roboto-MediumItalic.ttf robotonormal roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotoregular roboto robotoregular ./fonts/Roboto/Roboto-Regular.ttf robotothin roboto robotothin ./fonts/Roboto/Roboto-Thin.ttf robotothinitalic roboto robotothinitalic ./fonts/Roboto/Roboto-ThinItalic.ttf 4. Using `\definedfont[name:robotomedium*default] hello` and `\definedfont[file:Roboto-Thin*default] hello` (for example) work exactly as expected I hope this isn't a silly question, I'm very new to ConTeXt and have been struggling for a while so thought I may as well ask in case there's something I'm missing, would appreciate any guidance :) Regards, Matt

new uplaod
by Hans Hagen 17 Apr '23

17 Apr '23

Hi, I uploaded a new lmtx. Again some updated math of which details will be revealed later. Apart from some details we added suport for fourier notations. There are no high level definitions yet as we have to invent names but this is how it works (private unicode slots might change): \setupbodyfont[pagella] \starttext \setupmathdelimited [topoffset=.2\exheight] \definemathdelimited [fourier] [rule=no, left=\zerocount, right="FE944] \definemathdelimited [courier] [rule=no, left=\zerocount, right="FE946] \definemathdelimited [xourier] [rule=no, left=\zerocount, right="FE948] $ \fourier{(z+1)} $ $ \fourier{(z+1)} + \sqrt[2]{1}$ $ \fourier{(z+1)} + \courier{(z+1)} + \xourier{(z+1)} $ $ \fourier{\left(z+\frac12\right)} + \courier{\left(z+\frac12\right)} + \xourier{\left(z+\frac12\right)} $ $ \autofences \fourier{(z+\frac12)} + \courier{(z+\frac12)} + \xourier{(z+\frac12)} $ $ \widehat{x^2 + 2x + 2} $ \stoptext This example also shows a new \autofences feature and widehats (widetilde and widecheck also work that way) that overcome limitations in fonts, so \def\CrappyHack#1{\im{#1{a} + #1{a+b} + #1{a+b+c} + #1{a+b+c+d} + #1{a+b+c+d+e} + #1{a+b+c+d+e+f}}\par} \CrappyHack\widehat \CrappyHack\widetilde \CrappyHack\wideacute \CrappyHack\widecheck will work. For thise in finance we now have $ \annuity{x + 1} + \lannuity{x + 1} + \rannuity{x + 1} + \lrannuity{x + 1} $ these are basically radicals (like sqrt) with two sided symbols.

[m-database] How to properly add module arguments?
by Paul Mazaitis 04 Mar '23

04 Mar '23

Dear list, ## The Incredibly Short Version I am trying to extend m-database, and I want to add a flag to control behavior. I can get it to work, but I am having trouble understanding how to do it properly. ## The Short Version I have a project where I wish to incorporate many CSV files as Natural Tables. I want to keep the headers in the CSV files so they're useful in other contexts. The `m-database` module doesn't have a feature to suppress the header row, from what I can see. (I know `handlecsv` can do this, but I'm having troubles with that; if the `m-database` line of inquiry doesn't work out, I'll go back it, but I figure I'll focus on this solution for now.) Looking at the module sources, I can implement the functionality I need in the Lua part of the module, but: I seem to only be able to bodge in additional arguments for the commands in the module. On first try, I got the error: `tex error > tex error on line 30 in file /Users/pmazaitis/Opt/context/tex/texmf-context/tex/context/modules/mkiv/m-databaseplus.mkiv: ! Undefined control sequence` And then: `The control sequence at the end of the top line of your error message was never \def'ed.` Looking at the docs points me to a solution using `\def`, but it's not clear to me how that's working in the case of the database module (the database module seems to be initializing these values someplace else?). If I \def the settings variable in m-database.mkiv, I can get it to work, but I don't think that's the correct way to go about this. Question: how do I properly define new module arguments for the database module? ## The Long Version, With MWE ### Files Associated With the MWE Apologies for all of the file inclusions, but I want to be complete. Here's the .csv file I'm using for the MWE: --- begin database-mwe.csv --- Ref. No.,Part No.,Description,Remarks ,RD14C82E000J,Carbon 000𝝮 ±5% 1/4W, --- end database-mwe.csv --- Some notes on database-mwe.csv: I'd like to keep the header row in place to make this file useful for other tools. These are lists of electronic parts, so I'd like to include uppercase omega, lower case mu, and percent sign characters in the CSV file. Here's the .tex file I'm using for the MWE: --- begin database-mwe.tex --- \usemodule[database] \setupdatabase[quotechar={"},separator={,}] \defineseparatedlist [PartsTable] [separator=comma,left=\bTD,right=\eTD,first=\bTR,last=\eTR,before={ \bTABLE[split=repeat,option=stretch] \bTABLEhead \bTR \bTH Ref. No. \eTH \bTH Part No. \eTH \bTH Description \eTH \bTH Remarks \eTH \eTR \eTABLEhead \bTABLEbody }, after={ \eTABLEbody \eTABLE }] \starttext test \startasciimode \processdatabasefile[PartsTable][parts_list-test.csv] \stopasciimode \stoptext --- end database-mwe.tex --- Some notes on database-mwe.tex: This actually works pretty well with the distributed m-database module! Some of these lists are quite long, so I want to use a TABLEhead to replicate the headings at the top of a new page. I don't think there's a way to automate this with `m-database`, so I'm okay with hard-coding the headers. This does mean I get a double header row at the top of the table. I want to suppress the header row; I'd like to implement this behavior in the module behind a switch. (I'm using the `asciimode` environment to dodge problems with unescaped `%` characters and Greek letters. I tried adding the startasciimode/stopasciimode commands to various keys in the \defineseparatedlist command, but I didn't get anywhere with it - I got errors. A problem for another time...) I think I've got a good handle on how to do this in Lua, but I'm struggling with what to add to the switch appropriately. In attempting to add a switch, I tried the following. Based off of https://wiki.contextgarden.net/Modules#Modules_writing_guidelines, I added a stanza to the appropriate interface file: --- begin stanza added to i-database.xml --- <cd:parameter name="skipheader"> <cd:constant type="yes"/> <cd:constant type="no" default="yes"/> </cd:parameter> --- end stanza added to i-database.xml --- I modeled that after the stanza for the argument `strip`. I think that's the only thing I need to do in the interface file. Changing the i-database.xml file does not break the build. However, as soon as I add the skipheader argument to the m-database.mkiv file: --- begin definition in m-database.mkiv --- \setupdatabase [\c!separator={,}, \c!quotechar=, \c!commentchar=, \c!strip=\v!no, \c!skipheader=\v!no, % <- Added, following the pattern with strip \c!before=, \c!after=, \c!first=, \c!last=, \c!left=, \c!right=] --- end definition in m-database.mkiv --- ...the build fails (with the error from the Short Version section). If I then add the following \def to m-database.mkiv before the \setupdatabase command: \def\c!skipheader {skipheader} ...the build succeeds! I can now pass that settings value to m-database.lua and use it to modify the processing logic. My question: how do I \emph{properly} define new module arguments for the database module? Or: is adding extra \def commands the way to do it? Many, many thanks! -Paul

Bug with \startnarrow?
by denis.maier＠unibe.ch 04 Mar '23

04 Mar '23

Hi, While doing some more tests with my example from yesterday (tables in \startnarrow), I've realized that the example from the wiki doesn't seem to quite work as expected: %%%%%%%%%%%%%%%%%% \starttext Some text before \startnarrow[left=2cm,right=1cm,before={\blank[2*line]},after={\blank[halfline]}] narrower text \stopnarrow some text after \stoptext %%%%%%%%%%%%%%%%%% Already here, the extra margins on both sides seem to be equal. Changing the size of the left extra margin has no effect at all. %%%%%%%%%%%%%%%%%% \starttext \startnarrow[left=10cm,right=2cm] \input ward \stopnarrow but: \setupnarrower[left=5cm, right=2cm] \startnarrower[left,right] \input ward \stopnarrower \stoptext %%%%%%%%%%%%%%%%%% Is this a bug or intended behaviour ? Best, Denis

Float control
by denis.maier＠unibe.ch 02 Mar '23

02 Mar '23

Hi everyone, I've recently had to typeset a document that gave me some headaches with the floats. The floats where jumping around, appearing in a different order than in the source file, tables ended up split up at weird points, some positioning keys had not the intended effect (e.g. top), <page> moved the float more than seemed necessary for me... I know, TeX's float positioning algorithm should be rather reliable and stable, and it's quite possible that I'm messing things up in my setups-especially since my source files are XML. Anyway, I'd like to learn more about the whole float issue. Is there anything particular I could read to learn more about the whole thing? Maybe I'm missing out on something fundamental... Best, Denis
