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.

Reinserting a section title followed by (continued) after a page break
by Calvin Ross 04 Sep '23

04 Sep '23

I'm trying to use ConTeXt for playwriting, and I think it would be best to use sections for dialog. However, if a dialog's text is interrupted by a page break, it is customary to restate the character name followed by (continued) on the following page: --- open --- John My name is John, and I seek help with my --- page break --- John (cont'd) typesetting needs... --- end --- Maybe what I need is instead a mark? Here's a catch though, I will also need this to work for simultaneous dialog as well. This kind of dialog is represented by having dialog sections in columns: --- open --- Alice Bob John, you fool. John, you imbecile. --- page break --- Alice (cont'd) Don't you know that everyone uses Word to typeset their plays? --- end --- How can I do this kind of thing in ConTeXt? At the moment, I've been looking into adding a hook to shipout to prepend a section header with the last custom mark I've set. Even still, I don't know if this would work, or how to go about achieving this. If columns would be too difficult to implement, I'd be fine with living without (continued) support in them since they are pretty rare.

Dear all, I'm struggling to setup a nested itemize with no blank line and several columns. What I mean is something like 1. a) bla c) bla b) bla d) bla The following MWE is my starting point \starttext \startitemize[n] \item \blank[-line] \startitemize[a,horizontal,two] [margin=2cm] \item First \item Second \item Third \item Fourth \stopitemize \item \blank[-line] \startitemize[a,horizontal,columns,two] \item First \item Second \item Third \item Fourth \stopitemize \stopitemize \stoptext Thanks in advance

xml: matches always child of other element
by denis.maier＠unibe.ch 10 Aug '23

10 Aug '23

Hi, I must be missing something obvious, but in this example the pattern for <term> always matches the first element, not the one under the current <index-entry>. Interestingly, using xml:index-entry-2 instead of the normal version matches correctly... Any hints what is going off the rails here? Best, Denis \startxmlsetups xml:test \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{index}{xml:*} \xmlsetsetup{#1}{index-entry}{xml:index-entry} %\xmlsetsetup{#1}{index-entry}{xml:index-entry-2} \xmlsetsetup{#1}{term}{xml:index-entry-term} \xmlsetsetup{#1}{nav-pointer-group}{xml:*} \xmlsetsetup{#1}{nav-pointer}{xml:nav-pointer} \xmlsetsetup{#1}{nav-pointer/ext-link}{xml:nav-pointer-link} \stopxmlsetups \xmlregisterdocumentsetup{test}{xml:test} % Index \startxmlsetups xml:book-back \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:index \startsectionlevel[title={\xmlfilter{#1}{/index-title-group/title/command(xml:index-title)}},] \xmlflush{#1} \stopsectionlevel \stopxmlsetups \startxmlsetups xml:index-title \xmlflush{#1} \stopxmlsetups \definedescription[indexentry] [alternative=top, headstyle=normal, headcommand=\hskip-1cm, margin=1cm, inbetween=, ] \startxmlsetups xml:index-entry \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:index-entry-2 \xmlfilter{#1}{/term/command(xml:index-entry-term)}% \xmlverbatim{#1} \stopxmlsetups \startxmlsetups xml:index-entry-term \indexentry{\xmlflush{#1}} \stopxmlsetups \startxmlsetups xml:nav-pointer-group \xmlconcat{#1}{/nav-pointer}{, } \stopxmlsetups \startxmlsetups xml:nav-pointer \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:nav-pointer-link \xmlflush{#1} \stopxmlsetups \startbuffer[test] <?xml version="1.0" encoding="UTF-8"?> <index> <index-title-group> <title>Index</title> </index-title-group> <index-entry> <term>First</term> <nav-pointer-group> <nav-pointer> <ext-link>1</ext-link> </nav-pointer> <nav-pointer> <ext-link>2</ext-link> </nav-pointer> <nav-pointer> <ext-link>3</ext-link> </nav-pointer> </nav-pointer-group> </index-entry> <index-entry> <term>Second</term> <nav-pointer-group> <nav-pointer> <ext-link>1</ext-link> </nav-pointer> </nav-pointer-group> </index-entry> <index-entry> <term>Third</term> <nav-pointer-group> <nav-pointer> <ext-link>1</ext-link> </nav-pointer> </nav-pointer-group> </index-entry> </index> \stopbuffer \starttext \xmlprocessbuffer{test}{test}{} \stoptext

Can ConTeXt write its pdf to a different directory?
by peter.hopcroft＠icloud.com 07 Aug '23

07 Aug '23

My .tex file is in a directory within my working directory. I would like ConTeXt to write its output in the same directory as my .tex file. But it writes to the working directory. This was asked 10 years ago: `tex.stackexchange.com/questions/67928/how-to-set-output-directory-in-context-command` The answer given then was to use: `context filename --result=output-directory/filename` But this doesn't work now. When I compile my .tex file, I get a message: `results are to be on the running path, not on 'output-directory', ignoring --result` I've looked in the wiki: `https://wiki.contextgarden.net/Context` Thank you, Peter

Par Builder Tests
by Keith McKay 05 Aug '23

05 Aug '23

Hi all, At the end of June, Hans uploaded a new lmtx version which included improvements to par building which he and Mikael had been working on in math mode. Hans suggested in the online chat that these improvements may be useful in typesetting novels. I was keen to try these since I have typset novels in the past. I have ran some tests on two novels which I downloaded from the Gutenberg Project site as epubs and extracted them to get the original xhtml files which I then typeset in context. I made very little in the way of changes to the files so that my setup for xml was very simple. Here are my setups for the layout of the novels showing some trackers that were used as well: \definepapersize[pagee][width=5.06in,height=7.81in] \setuppapersize[pagee] % XML setups here \startsetups[grid][mypenalties] \setdefaultpenalties \setpenalties\widowpenalties{1}{150} \setpenalties\clubpenalties {1}{150} \stopsetups \setuplayout[ width=10cm, topspace=0.5in, backspace=2.0cm, header=7.5mm, footer=0.25in, location={middle,middle}, vs=2, grid=yes, setups=mypenalties ] %\enabletrackers[makeup] %\enabletrackers[builders.hpack.quality] \enabletrackers[builders.hpack.overflow] %\enabletrackers[layout.vz] %\enabletrackers[paragraphs.passes] \enabletrackers[paragraphs.passes=summary] %\enabletrackers[paragraphs.passes=details] \setupalign[granular] %\setupalign[nothyphenated,hz,verytolerant] %\setupalign[vertical,height] %\setupalignpass[decent] %\setupalignpass[quality] %\setupalignpass[test1] \setupalignpass[test2] %\setupalignpass[test3] %\setupalignpass[test4] %\setupalignpass[test5] %\setupalignpass[optional1] %\setupalignpass[test2b] \starttext \setuppagenumbering[location={footer,middle},alternative=doublesided,state=start] \setcounter[userpage][1] %\showmakeup[vbox] %\showlayout \dostepwiserecurse{0}{30}{1}{ \xmlprocessfile{mysetups}{/path to xhtml files/4439720318703948998_84-h-\recurselevel.htm.xhtml}{} } \stoptext Below are the result showing the number of overfull boxes for these novels using the setups in the file spac-imp-tests.mkxl . See the manual Low Level - Lines Test Novel1 Novel2 Test1 70 35 Test2 30 8 Test3 62 23 Test4 89 40 Test5 28 9 Optional1 55 19 Quality 74 32 Decent 39 11 From these initial tests one can see that Test2 gave the lowest number of overfull boxes. So I edited test two, ran it, and the results are below. Test Novel1 Novel2 Test2b 11 0 My setup for test 2b is as follows: \startsetups align:pass:test2b \pretolerance 100 \tolerance 200 \parpasses 3 classes \indecentparpassclasses threshold 0.025pt tolerance 800 extrahyphenpenalty 50 next threshold 0.025pt tolerance 900 adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 10 adjustspacingstretch 15 next threshold 0.025pt tolerance 1000 adjustspacing 3 adjustspacingstep 1 adjustspacingshrink 20 adjustspacingstretch 40 emergencystretch .25\bodyfontsize \relax % \linebreakpasses\plusone \stopsetups The only difference between test 2 and 2b are that I increased the tolerance in each of the three passes. In novel 2 this was successful in eliminating the overfull boxes but not in Novel 1 although I noticed that majority of overfull boxes were above 1pt with the largest about 12pt in Novel 1. I am at the stage now where I need some kind of strategy to reduce/eliminate overfull boxes, other than changing the tolerance, and I'm hoping for some advice from the community. Suggestions for further reading particularly on the commands in \setupalignpass and their usage would be appreciated and on the best way to tackle overfull boxes. Best Wishes Keith McKay
