syntax highlighting: pandoc uses Kate
by Henning Hraban Ramm 30 Sep '24

30 Sep '24

Hi, since we recently discussed editor support and syntax highlighting: Pandoc can use definitions from Kate[1] for syntax highlighting in a code block via "--syntax-definition". There’s also ConTeXt support (MkIV/LMTX): https://kate-editor.org/syntax/data/syntax/context.xml Apparently, it can switch contexts to Lua, XML, MetaPost etc. But the list of commands is quite short. In case the author (Philipp A.) is listening: Is this intentional (“not necessary, highlight everything that starts with a backslash”)? Otherwise it probably would make sense to read in the interface files (i-*.xml). I can’t tell if it would make sense to support this syntax via a module (like scite and vim). What we have if probably enough for most of us. Hraban [1] List: https://kate-editor.org/syntax/ Specs: https://api.kde.org/frameworks/syntax-highlighting/html/

ConTeXt Journal 2022 finally online
by Henning Hraban Ramm 29 Sep '24

29 Sep '24

I just uploaded the articles from 2022: https://articles.contextgarden.net/journal/2022.html For 2023, there’s the table of contents, but as usual, we’ll wait a few months with the PDFs. (They’re already prepared.) (Thanks to Taco who did it up to 2021 and provided me with a script to simplify the task.) Hraban

first line in different font
by Thomas Meyer 29 Sep '24

29 Sep '24

Hi guys, Is it possible to set the first line of an indented paragraph in a different font? I saw it in a book. There, the first line was indented to half the line width (\setupindenting[yes, .5\textwidth]) and set in smallcaps. Any hints? Thanks in advance Thomas

Indexing redux
by Rik Kabel 28 Sep '24

28 Sep '24

Hello experts, Is there a way to generate an entry without a page number in an register that has page numbers enabled? This would enabled /See also/ entries to be generated with something like \setregisterentry[TopicIndex][keys:2=zzz,entries:1=punctuation,entries:2={{\em See also} marking}]% I do see that there is an alternative key defined for the command, but no explanation of what the alternatives are and if any would help. -- Rik

index entry with sorting and processor
by Henning Hraban Ramm 27 Sep '24

27 Sep '24

Hi again, the page number of register entries from a glossary should have a different color: \defineprocessor[glossar][color=green] \define[1]\GlIndex{\index[glossar->]{#1}} This works, but I’d like to apply a macro to the text, and then I need to set the sort order: \define[1]\GlIndex{\index[glossar->#1]{\Word{#1}}} This also works, but I get separate index entries from \index{Something} and \GlIndex{something} Glossary entries may be lowercase, but in the index I’d like to normalize to uppercase initials. (The index command is part of a lemma setup.) How can I combine the entries? I also tried \setregisterentry but didn’t find out how to use a processor for the page number. In the wiki, the (generally working) processor option is undocumented, so if there’s another option, it’s also missing. In the source, I found processors for entry & page, but not how to address the latter. MWE: """ \defineprocessor[glossar][color=green] \define[1]\GlIndex{\index[glossar->#1]{\Word{#1}}} \starttext \samplefile{ward} \index{something} \index{anything} \page \samplefile{tufte} \GlIndex{something} \GlIndex{anything} \page \placeindex \stoptext """ Hraban

Strange extra space when using cases in an inner align in math
by Gerion Entrup 27 Sep '24

27 Sep '24

Hi, I currently have the case of a strange extra space in math mode when using cases in inner align. Here is a MWE to demonstrate the problem: ``` \definemathsimplealign[inneralign] \startdocument \startformula \startalign \NC a = b \NR \NC \NC \startinneralign[n=3,align={1:right,2:middle,3:left}] \NC A \NC = \NC B \NR \NC f(x,y) \NC = \NC \startcases \NC \text{strange} \NC a \NR \NC \text{normal} \NC b \NR \NC \text{also normal} \NC b \NR \stopcases \stopinneralign \stopalign \stopformula \stopdocument ``` "strange" and "normal" are not aligned what I would expect but strange has more space in front of it. Is this a usage error or a bug in the math engine? Best, Gerion

suitable macros for Pandoc custom styles for paragraphs, spans and tables
by mf 26 Sep '24

26 Sep '24

Hello list, I started a topic in Pandoc discussions (see https://github.com/jgm/pandoc/discussions/10208) about custom styles in pandoc tables. This is the framework: - in Pandoc, some textual elements have a "custom-style" attribute, whose value becomes the name of a paragraph or character style in DOCX, ICML or ODT when exported to those formats - e.g. when you have a Span with custom-style="myStyle" around some inline text, you'll get a character style "myStyle" in those formats - for paragraphs, it's a bit different: since they have no attributes in Pandoc, you set the "custom-style" attribute of a surrounding Div element, then all the paragraphs inside it will get that custom paragraph style in DOCX, ICML or ODT - for DOCX output you may set a "custom-style" attribute also in tables Why not using that information about custom styles for ConTeXt output too? I started from the last ones (tables), suggesting that a Table element with a "custom-style" attribute set to "myStyle" could be output in ConTeXt as: \startxtable[myStyle] (Currently, tables converted to ConTeXt by Pandoc start only with a "\startxtable" line) That's doable, because ConTeXt does not terminate with an error, when it encounters a \startxtable[myStyle] not preceded by a \definextable[myStyle]. Then JGM, Pandoc's main author, replied that it would be weird having custom styles for tables and not for spans or paragraphs in ConTeXt output. Good point. In ConTeXt, there are many ways to specify what in Word and LibreOffice are "character" and "paragraph" styles. For example, \definehighlight is suitable for character styles. Badumont, in the pandoc discussion, suggested \definestartstop; good, though you should be careful not to specify a custom style with the same name of an existing environment (e.g. "narrower"); maybe a prefix like "CS" could be a workaround, so that "myStyle" becomes "CSmyStyle", and also "narrower" becomes a less dangerous "CSnarrower". Also, in this case, Pandoc should prepend a \definestartstop[CSmyStyle] before \startCSmyStyle, otherwise ConTeXt would terminate with an error (I think this is doable in Pandoc code, anyways). (BTW, the wiki says \definestartstop is "used to define block level commands": does it mean it can't be suitable for spans of inline text in a paragraph?) Any ideas to specify paragraph and character styles? Massi

As a person with very basic LaTeX skills, no experience with programming languages and an interest in LMTX (I have been coding extremely basic LMTX), how do I properly learn LMTX as a beginner to any coded language?
by Felix 25 Sep '24

25 Sep '24

I am someone who knows very basic LaTeX (I mostly learned with YouTube videos, but I would also honestly use AI to generate some code that I wanted it to make), extremely basic LMTX, and nothing like C++ or anything that I think would be considered "proper" programming languages. I have an interest in learning the newest edition of ConTeXt, but I am not sure if there is anything that could even guide a beginner wanting to learn the newest edition of ConTeXt (I believe MKIV and LMTX are regarded as being quite different). I want to get out of the habit of using AI to make stuff for me and to truly understand LMTX, but how can I do so if I seemingly do not have much understanding of ... I'll say "coding" in general? It is sometimes hard for me to read the documentation on ConTeXt garden, and I don't understand some things, but is this due to my lack of experience of looking at documentation? I would love any advice given to me.
