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.

list of modules: need changes/testing/response
by Henning Hraban Ramm 03 Sep '23

03 Sep '23

Hi all, esp. module authors! I went through the list of modules on https://modules.contextgarden.net/ (dl/) and the list that controls module installation for “--script install-modules". I removed all font-related modules from the list (not yet from the garden), since they’re probably all obsolete & outdated. Consider publishing typescripts in the wiki. The following modules don’t adhere to the necessary structure and need changes: * t-handlecsv (2023, Pablo) * metaducks (2021, Jairo) * presvoz (2023, Pablo) All of them have a name directory on top of the TDS (tex, doc). If you used a git checkout URL, please try again, for me it worked today. Several modules need testing if they still work and make sense. If their authors are present, I’d appreciate a comment if we should keep them. I’d like to delete at least everything older than 10 years. * grph-downsample.lua (2019) is known to fail in current LMTX (I hope for an integrated solution during the meeting.) t-degrade (2018) is AFAIK an older version of it – delete? * high (2018) and pret-c (2018) are syntax highlighters. Are they better than the vim and scite modules? Does it make sense to keep/update them? * karnaugh (2021, VicSanRoPe; probably OK, I just don’t understand it) * t-account (2009, Wolfgang) * t-algorithmic (2013, Wolfgang) * t-animation (2013, Wolfgang) * t-annotation (2013, Wolfgang) * t-bnf (2006, Now) * t-chromato (2008, Peter) * t-construction-plan (2008, Peter) * t-crossref (2016, Zenlima) * t-cyrillicnumbers (2016, Philipp) * t-fancybreak (2015, Wolfgang) * t-french (2011, Peter) * t-fullpage (2017, Wolfgang) * t-gantt (2012, Adam) * t-gm (2015, Luigi) * t-gnuplot (2013, Mojca) * t-greek (2013, Thomas – is this more than fonts?) * t-gs (2015, Luigi) * t-inifile (2008, Peter) * t-layout (2007, Patrick) * t-letterspace (2016, Philipp) * t-mathsets (2011, Aditya) * t-rst (2016, Philipp) * t-rsteps (2006, David) * t-simplebib (2016, Zenlima) * t-taspresent (2008, Thomas – AFAIK an old version of simpleslides) * t-title (2017, Wolfgang) * t-transliterator (2021, Philipp) * t-typearea (2008, Peter) * t-visualcounter (2018, Aditya, isn’t there a newer version?) Modules not mentioned are probably fine. Hraban

Building luametatex with Lua symbols exposed
by Jairo A. del Rio 02 Sep '23

02 Sep '23

Hi, beloved list. Since sources are in the distribution, I've tried compiling luametatex by setting LMT_STRIP in CMakeLists.txt to 0, yet the resulting binary still warns about undefined symbols, such as lua_gettop, when an external library is loaded in Lua. Any ideas on how to solve it? Thank you in advance. Best regards, Jairo

Kerning feature not working

Dear List In the MWE below, the kerning feature works OK for ebgaramonditalic but not for ebgaramondregular. How do I fix it? I'm using ConTeXt version: 2023.08.27 13:48 \startluacode fonts.handlers.otf.addfeature { name = "kernit", type = "kern", nocheck = true, data = { [0x27E8] = { ["f"] = 300, ["ﬁ"] = 300, ["ﬂ"] = 300 } } } \stopluacode \definefontfeature[kernit][mode=node,kernit=yes] \starttext \definedfont[name:ebgaramondregular*default,kernit] ⟨f ile ⟨f lame ⟨file ⟨flame \definedfont[name:ebgaramonditalic*default,kernit] ⟨f ile ⟨f lame ⟨file ⟨flame \stoptext -- Todas as coisas fatigam o corpo, salvo a música, que não fatiga nem o corpo nem seus membros, por ser descanso da alma, primavera do coração, distração do aflito, entretenimento do solitário, e viático do viajante.
