serial letters
by Henning Hraban Ramm 11 Nov '24

11 Nov '24

How would you approach serial letters, e.g. to all members of a club? (Actually I need to send out donation receipts.) I’d like to use the letter module, since my usual letter design is using it. I can export the addresses to CSV, JSON, Lua tables or whatever or transfer them to a SQLite db. Would it make more sense to read them in Lua and combine this data with a buffer, or to write a single tex file for every letter? I know how to do the latter, but I’d like to learn a more ConTeXt-ish way. Would it make sense to use the bibliographies module?

Hi, Please find attached a new version of the module, with some ideas from Marco. Later, I'll upload it to modules.contextgarden.net. Here a usage example: \usemodule[downsample] \setupexternalfigures[ location=default, % find hacker.jpg and mill.png cache=/tmp, % where to put the low resolution images resolution=50, % resolution in DPI conversion=downsample.pdf] % use this module \starttext \externalfigure[hacker][width=0.4\textwidth] \setupexternalfigures[resolution=20] \externalfigure[mill][width=4in, height=3in] \setupexternalfigures[resolution=200] \externalfigure[mill][width=4in, height=3in] \stoptext Hans, it would be nice, to apply this patch, to trigger new conversion, when figure dimensions change: --- grph-inc.lua~ 2019-02-14 17:04:12.000000000 +0100 +++ grph-inc.lua 2019-02-17 08:45:38.129971581 +0100 @@ -864,6 +864,14 @@ newbase = prefix .. newbase end local hash = "" + local width = figures.current().request.width + local height = figures.current().request.height + if width then + hash = hash ..

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

Re: [NTG-context] checkbox in fields show the word yes
by Andres Conrado Montoya 05 Oct '23

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.

Re: [NTG-context] \typefile not including file and returning success

It's a workaround at least. But context returning success when it clearly doesn't include the file is unfortunate. The missing file might go completely unnoticed. I'd expect an error there. Marco
