Using legacy math fonts
by Henri 09 Aug '17

09 Aug '17

Dear list, Because I don't like that Euler calligraphic script provided by Latin Modern Math, I want to revert to Computer Modern for the uppercase calligraphic letters. I got so far, that the command will produce the correct glyphs, however, the kerning is borken. What did I miss?

methods for numbered paragraphs (ii)
by Idris Samawi Hamid ادريس سماوي ح امد 09 Aug '17

09 Aug '17

[Sent this a couple of days ago, maybe will get some takers this time -)] Dear syndicate, Not sure if there is a canonical way to do numbered paragraphs. In the following, I use subsections to mimic numbered paragraphs: =======section-intext.tex======= \setuphead[section][style=\bfa,after={\blank[big]},before={\blank[big,medium]},color=walayahblue] \setuphead[subsection][style=\bf,after={\blank[big]},before={\blank[big,medium]},color=walayahgreen,alternative=text,distance=0.28em] \setuphead[subsubsection][style=\tf,after={\blank[big]},before={\blank[big,medium]},color=walayahred,alternative=text,distance=0.28em] \starttext \startsection[title=Section 1] \startsubsection \input ward \stopsubsection \startsubsection[title=Paragraph 2] \input ward \stopsubsection \startsubsection \startparagraph \input ward \stopparagraph \stopsubsection \stopsection \stoptext ============== See attached output. In paragraphs 1 and 2, there is too much distance between the subsection number (subsection number + title in paragraph 2) and between the text. The distance parameter is not appropriate here, it is the distance *after* the section head that needs adjustment (even if the text portion of the head (i.e., the section title) is empty). Question 1: How do we fix the post-head distance? Paragraph three shows that one apparently cannot mix this sectioning approach with the \start-stopparagraph mechanism. Question 2: Is there a way to mix \start-stopparagraph with the above subsection approach to par numbering? I suppose that as long as I maintain exactly one paragraph per subsection, then structured output (xml etc.) should look ok. Question 3: Is there a wiser way to handle this kind of par numbering in mkiv? Thanks in advance!

Could you look at this?
by Idris Samawi Hamid ادريس سماوي ح امد 08 Aug '17

08 Aug '17

Hi Hans, https://mailman.ntg.nl/pipermail/ntg-context/2017/089431.html For the current writing project: It seems I've gotten about as far as I'm going to get on the list with this. Could you kindly take a look at the two automation challenges at the end of the message when you get a chance? Eventually we want to also get, e.g. 1.01 2.01 etc. but the full decimal version is a start. Here is a link to the book that illustrates the layout: https://www.dropbox.com/s/q7znlu0y362abno/Mure-Introduction-to-Hegel-OCR.pd… Thanks in advance for your help.

comment colors in \typebuffers
by Pablo Rodriguez 08 Aug '17

08 Aug '17

Hans, I have the following sample: \starttext \startTEXpage[offset=1em] \startTEX This is text. % and this is a comment \stopTEX \startXML <p>This is text.</p> \stopXML \startLUA if code=="code" then --this is a comment --[[ and this is a multiline comment --]] \stopLUA \stopTEXpage \stoptext All comments are colored in darkyellow, but the issue is that in Lua and TeX only the comment markers are colored, while in XML only the comment content is colored. Because it is basic to display what it won’t affect to the interpretation or compilation of the code, would it be possible that the whole comments (both markers and content) could be colored? Sorry, but in all the code editors I have used in my life, comment coloring involved both markers (or delimiters) and content. Many thanks for your help, Pablo -- http://www.ousia.tk

concatenating attribute values in XML
by Pablo Rodriguez 07 Aug '17

07 Aug '17

Dear list, I have the following definition: \startxmlsetups xml:image:sidebyside \blank\startalign[center] \dontleavehmode \externalfigure[\xmlattribute{#1}{./p/img}{src}] [width=.5\textwidth] %~ \xmlconcat{#1}{./p/img}{ } \stopalign\blank \stopxmlsetups How can I define the external figure so I concatenate the image file names in the code above? I mean, \xmlconcat is great, but I don’t see how I could make it work to get values from the src attribute. Many thanks for your help, Pablo -- http://www.ousia.tk

Help with xml & lua
by Olivier Binda 07 Aug '17

07 Aug '17

Hello I have been trying for the past 3 days to process files with xml on the lua side (with Context beta 0.70), but I'm at then end of my wits and really need help. On the lua side, I would really like to be able to : 1) transform a tree : replace nodes with other nodes 2) transform a tree : walk it and modify node attributes 3) walk a modified tree and flush it with setups Could someone give me hints or better yet a lua snipet that : 1) load a tree in lua 2) modify it 3) walk it 4) it can be done again I have had some success with 1, but lost 2 days trying to make 2 & 3 work with setups A) I managed to replace a node of an xml document with a subtree of another xml document by doing : -- load the main tree local mainTree = lxml.load("mainTree", "mainFile.xml) local replacementNode = xml.first(lxml.load("replacement", "replacementFile.xml), somePattern) -- replace nodes for node in xml.collected(tree, pattern) do node.tg ="toBeReplaced" xml.replace(tree, "toBeReplaced", replacementNode) end But then I failed to walk the modified tree with setups : my setups for "mainTree" work, but not for the inserted subtrees B) So, to process my tree further, I need to first serialize it -- save the modified tree xml.save(mainTree, "saved.xml") And then, I can reload the modified tree and work further with it (but it sucks to have to save to reload). C) "xml.replace" works in a weird way : it erases node (toBereplaced) and inserts the children of replacementNode as children of the parent of the node to be replaced... D) I did not manage to walk a tree loaded with xml.load in lua. I know that I have to register setups, I tried all sort of things, looked at the Tex/Lua context source code but could not make it work. Also the xml documentation for context on the net is really old, sparse and obsolete. On the tex side, it works : \xmlprocessfile{mySetups}{saved.xml}{} works like a charm But the TeX commands don't allow you to grab a modified xml tree, once you have walked it E) I tried lxml.load(id, filename) context("\\xmlregistereddocumentsetups{" .. id .. "}{}") Best regards, OlivierBinda
