Reading XML with lua
by Axel Kielhorn 06 May '19

06 May '19

Hi, I’ m finally at a point where I can read an XML file look at it and write it back. Right now I have two problems: 1. There are many empty entries in the table. This makes processing the file a little tedious since I have to filter the real entries. 2. Some entries contain leading and trailing whitespace and linkebreaks. These are the result of formatting the XML file. Shouldn't strip_cm_and_dt take care of them? Or do I use that incorrectly? I have included my lua file and an example xml. You can run it with mtxrun —script p.lua Greetings Axel

Unicode mathematics in ConTeXt
by Hamid,Idris 04 May '19

04 May '19

Dear gang, I need to convert a document from TeX-style to Unicode mathematics. For example: \starttext \def\ANTI{{^{\rm nt}}} \def\CATCA{$\cal \bf C\ANTI$} \CATCA \stoptext Issues: 1. I need calligraphic characters, but the relevant characters in latinmodern-math.otf are not encoded in (standard) Unicode. The same goes for the tex-gyre-math fonts. 2. What comprehensive unicode-math fonts do you recommend as an alternative? 3. In the above example, \cal is used. 4. Other issues may arise, e.g., getting subscripts and superscripts correct. How might one rewrite the above with Unicode mathematics in mind? Is there a My Way or some other guide to Unicode mathematics in ConTeXt? This writer has never had to think about this matter before so this is all new ground to learn. Thank you in advance for any guidance. Best wishes Idris -- Idris Samawi Hamid, Professor Department of Philosophy Colorado State University Fort Collins, CO 80512

XML xmldoif struggle!
by Geert Verhaag 03 May '19

03 May '19

Hi, I've the following XML tag in my XML file: <invoice number="194-002" client="RPMB-0012"> <currency>EURO</currency> ..... with invoice being the root tag! Now I have a setup defined as below (only part!): \startxmlsetups xml:invoice:invoice \xmlfirst{#1}{currency} \par \xmldoif{\xmlfirst{#1}{currency}}{contains(text(),'EURO')} { Euro set! \par } ..... The \xmlfirst{#1}{currency} command prints EURO as expected. But the xmldoif command doesn't cause the Euro set be printed?! What's wrong here? The manual xml-mkiv.pdf doesn't give me any hint on how to make this work! Regards, Gerard --

Hyphenation questions
by Dmitry Starostin 01 May '19

01 May '19

1. is there an analog to \hyp{} command from the 'hyphenat' package? Double words with a dash happen all too often. 2. how to switch language for just three words for correct hyphenation? 3. if the citation in APS format falls out of the right margin, what needs to be changed to adjust it? 4. In APS, I cannot figure out how to make a space appear between the numbers for cited sources. [1, p. 1,2, p. 2]. But [1, p. 1, 2, p. 2] is what is desired. In one case it did appear automatically, but all others don't work. \cite[righttext={{{, p.~1}},{{, p.~2}}}][book1,book2]

How to write a wiki page?
by Rudolf Bahr 01 May '19

01 May '19

Hello All! I'd like to write a wiki page on special Fraktur fonts, but I don't know how to begin technically. Are there rules? Certanly, but where? To whom would I send the result to correct it with respect to format, ConTeXt commands, English language, bringing it into the ConTeXt wiki and so on? Greetings, Rudolf

13th International ConTeXt meeting
by Taco Hoekwater 01 May '19

01 May '19

TL;DR: See https://meeting.contextgarden.net/ for registration! Hi all, Registration for the next ConTeXt meeting is now open! 13th International ConTeXt Meeting ================================== The thirteenth ConTeXt meeting will take place in Bassenge, Belgium on September 16–21, 2019 You are cordially invited to join the 13th ConTeXt meeting. The meeting will host ConTeXt and LuaTeX developers and users and gives you the opportunity to present your results, experiences and ideas on future development. The talks will be followed-up by tutorials on different ConTeXt and LuaTeX techniques. Thematic context ================ The theme for this meeting is: dirty tricks & dangerous bends So we are particularly interested in submissions relating to either: • Sneaky ways to get ConTeXt to do exactly what you want, or • How to properly control ConTeXt is complicated environments The programme committee is Hans Hagen and Taco Hoekwater. Since not every dirty trick or dangerous bend is exciting enough to warrant a standalone presentation, we are also collecting small submissions separately that we will then combine into a single talk. Please email Hans or me with ideas. Social context ============== Registration opened today. We will be back in ’t Sjetootje in Bassenge-Boirs, the same location as the meetings in 2011 and 2014. There has been some remodelling (there is now an actual conference room with built-in wifi!) but the basic layout of the chateau has not changed so, as before, (single) rooms are very scarce. Note that the meeting starts on Monday evening and ends on Saturday morning. It is possible to stay on for another day (or even two, if you are OK with getting up early on Monday the 23rd). Arriving early is not possible, though. Jan (our previous host) is no longer attached to the chateau but a replacement has been found and there will still be special Belgian beers (and a marking list!). Calendric context ================= • May 1, 2019, beginning of registration • July 1, 2019, deadline for early bird payment • September 16-21, 2019, 13th ConTeXt Meeting See https://meeting.contextgarden.net/ for more details. Hope to see you there, Taco (your local organizer this year)
