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 ..

Unicode normalization and Hebrew in ConTeXt
by Joey McCollum 18 Aug '21

18 Aug '21

I am typesetting a document in Hebrew that includes pointing (e.g., vowels, shin and sin dots, dagesh, etc.) using ConTeXt. The Hebrew text that I want to typeset has been normalized into Unicode's NFC canonical form. It is well-known that the Unicode canonical ordering of Hebrew points conflicts with the recommended mark ordering of specific points based on their functions (see https://www.sbl-site.org/Fonts/SBLHebrewUserManual1.5x.pdf for more on this topic). Thankfully, many typesetting engines automatically reorder the points to ensure that they are combined according to the specifications of many fonts. I'm pretty sure that XeLaTeX is one of these, as it typesets Hebrew letters with multiple points correctly even when the Hebrew text is in NFC form. My question is, can ConTeXt with LuaTeX handle the same situation correctly? In the following minimal example, ConTeXt typesets pointed Hebrew correctly when the characters are in the typographically recommended order, but not when they are in Unicode canonical order: ``` %Setup Hebrew text font: \definefontfeature[f:pointedhebrew][default][ ccmp=yes, mark=yes, script=hebr ] \definefontfamily[hebrew] [rm] [SBL Hebrew] [features=f:pointedhebrew] %Set the body font: \setupbodyfont[hebrew] %Set up right-to-left alignment: \setupalign[r2l] \starttext %Characters after normalization, in Unicode canonical order (bet + segol + dagesh + final nun): בֶּן %A word with characters in typographically recommended order (bet + dagesh + segol + final nun): בֶּן \stoptext ``` I typeset this using ConTeXt version 2020.03.10, as released with TeXLive 2020. I got the SBL Hebrew font from https://www.sbl-site.org/educational/BiblicalFonts_SBLHebrew.aspx. According to the font's user manual (see the link above the MWE), the font should be able to combine the marks to form the correct glyph regardless of their order after the consonant, but that doesn't seem to be the case here. I also tried using the predefined "hebrew" featureset, but that did not change anything. Is there some other OpenType feature or featureset I need to enable to fix this, or is there some module or option I can include to get ConTeXt to typeset Unicode-normalized Hebrew as if it were ordered in the recommended way, like XeLaTeX does? I see that the uninormalize module is mentioned in the thread "XeLaTeX, LuaLaTeX, fontspec, unicode and normalization" on TeX Stack Exchange ( https://tex.stackexchange.com/questions/229044/xelatex-lualatex-fontspec-un…) can that be used with ConTeXt? Thank you, Joey

Hi, I use the lua function img.scan{filename}, but in lmtx I get "attempt to index a nil value (global 'img')", so I guess this got renamed or moved? HR

Undefined control sequence: \pdfpxdimen
by Aditya Mahajan 22 Jun '20

22 Jun '20

The drops module uses the primitive \pdfpxdimen in a couple of places, but that is no longer defined in the current beta. What is the equivalent command now? Examples of usage: \pdfpxdimen1in\relax\divide\pdfpxdimen\numexpr\dropsparameter\c! resolution\relax % set actual pixel dimension Aditya

Blank page added after pagecolumns
by Joey McCollum 16 May '20

16 May '20

I am typesetting a document using pagecolumns to ensure that my footnotes are set ragged-bottom in columns. I have observed some unexpected behavior whenever the last column on a page is left incomplete: a blank page is added at the end of the document. A minimal working example follows: ``` \starttext \startpagecolumns[n=2] \dorecurse{3}{\par\input zapf} \stoppagecolumns \stoptext ``` I typeset this using ConTeXt version 2020.03.10, as released with TeXLive 2020. Notably, if \dorecurse{3} is changed to \dorecurse{2} or \dorecurse{6} (so that the text ends in the first column of a page), then there is no problem. I have tried to fix this by specifying page=no in the \startpagecolumns arguments, but it did not change anything. Is there something else I am missing? Thank you, Joey

complete cover example
by jbf 12 May '20

12 May '20

Am wondering if anybody has a complete example (explained below) of a book cover: front, spine and back. It doesn't matter how simple or complicated the example. Am one of those people who, once he sees an example, can generally work out the necessary adaptations. By a complete example I mean the kind of thing found here Creating a style file in ConTeXt | Random Determinism <https://randomdeterminism.wordpress.com/2009/10/21/creating-a-style-file-in…> where the writer explains things bit by bit but importantly, offers a summary of the code at the end. I probably don't need the lengthy explanation but the summary of code is most helpful - except that it is not about a book cover:-) As a relative newcomer to ConTeXt, I have found complete examples of something I want/need to do very useful. Of course, many such are on the wiki, but from time to time I need something else, and right at the moment I need a bit of guidance for a book cover, and an example might help. Julian
