XML: Correct usage of hash symbol in url
by denis.maier＠unibe.ch 27 Aug '23

27 Aug '23

Hi, I need to process URLs in XML documents differently depending on the target. Thanks to Hans and Thomas I can now deal with the attributes. Now I need to prefix certain kind of targets with a certain URL (a web viewer for IIIF images in this particular case). The prefix contains a #, which, as a special character seems to cause an error. Adding a double hash seems to work, but those ## will end up in the link URL. How can I properly escape a single #? I've already tried using \Ux{23}, but that won't work either.

xmldoif: checking for contents of attribute
by denis.maier＠unibe.ch 25 Aug '23

25 Aug '23

Hi, I'm trying to check whether an attribute contains (or, actually starts with) a given string. I've tried a whole bunch of different combinations, but I've had no luck so far. Minimal example below. Anyone has a hint? Best, Denis %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% \startxmlsetups xml:test \xmlsetsetup{#1}{*}{-} \xmlsetsetup{#1}{doc|element}{xml:*} \stopxmlsetups \xmlregisterdocumentsetup{test}{xml:test} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:element \xmlfilter{#1}{./find(attribute('class'), 'abc')/command(xml:whatever)} \xmldoifelse{#1}{./attribute('class')/contains('abc')} {Yes}{No} \stopxmlsetups \startxmlsetups xml:whatever Yes \stopxmlsetups \startbuffer[test] <?xml version="1.0" encoding="UTF-8"?> <doc> <element class="abcdefg">Yes</element> <element>No</element> </doc> \stopbuffer \starttext \xmlprocessbuffer{test}{test}{} \stoptext

Question about building an array of values with Lua

Fallbacks for design sizes in the current typescripts regime
by Hamid,Idris 23 Aug '23

23 Aug '23

Dear gang, Design sizes for typefaces -- aka "optical sizes" -- are no longer directly implemented in typescripts. From the manual Fonts out of ConTeXt by Hans Hagen, p. 109: "at some point the decision was made to kick out these definitions and move the burden of figuring out the right size to Lua." (Thus some large typescript collections painstakingly built over the years are now obsolete and have to be rewritten. Oh well..) But there is an issue in the new regime: In the old system, every typescript mapping to a font within a design-size range could have its own fallback. For example: % Small ="small point size" % Regular = "regular point size" % Bigger = "bigger point size" % Biggest = "biggest point size" \definefontsynonym [MyRomanRegular] [file:MyFont-Regular.ttf] [features=<features>,fallbacks=<fallback1>] \definefontsynonym [MyRomanSmall] [file:MyFont-Small.ttf] [features=<features>,fallbacks=<fallback2>] \definefontsynonym [MyRomanBigger] [file:MyFont-Bigger.ttf] [features=<features>,fallbacks=<fallback3>] \definefontsynonym [MyRomanBiggest] [file:MyFont-Biggest.ttf] [features=<features>,fallbacks=<fallback4>] In the new typescripts regime we keep one font from the design-size range in the typescript file; the rest of the optical sizes go into an lfg goodies file: \definefontsynonym [MyRomanRegular] \loadfontgoodies[myfonts-opticalsizes] % other three fonts go into an lfg table [file:MyFont-Regular.ttf] [features=<features>,fallbacks=<fallback1>] designsizes = { ["MyRomanRegular"] = { ["7pt"] = "file:MyFont-Small", ["8pt"] = "file:MyFont-Small", ["9pt"] = "file:MyFont-Regular", ["10pt"] = "file:MyFont-Regular", ["11pt"] = "file:MyFont-Regular", ["12pt"] = "file:MyFont-Bigger", ["14pt"] = "file:MyFont-Bigger", ["17pt"] = "file:MyFont-Biggest", ["21pt"] = "file:MyFont-Biggest", default = "file:MyFont-Regular", }, But there is an apparent drawback to this new way of doing things: It appears that only the default font can have an explicit fallback, and there appears that there is no straightforward way to map each of the other design sizes to its own fallback. If there is indeed no way to map each non-default design size to a fallback, then that constitutes a significant/unfortunate loss of functionality in the user interface. If this appearance of a loss reflects the reality of the situation, would like to kindly request that the original functionality be restored to the higher-level user interface, presumably within the lfg file. So perhaps something like a keyval fallbacks = { ["MyRomanRegular"] = { "file:MyFont-Small" = "fallbacks=<fallback2>", "file:MyFont-Regular", = "fallbacks=<fallback1>", "file:MyFont-Bigger", = "fallbacks=<fallback3>", "file:MyFont-Biggest", = "fallbacks=<fallback4>", }, On the other hand, if access to the former functionality is still there somewhere in the user interface, would like to humbly request that someone share where it is and how to use it! Thank you kindly for consideration of this request. Best wishes Idris -- Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523

An strange error with section and page
by Xavier B. 23 Aug '23

23 Aug '23

Hi, I have a long document [https://repo.or.cz/apunts-espa-matematiques.git/blob/HEAD:/ng-exercicis.con…] which I migrated from MKIV to LMTX version of ConTeXt. As Wolfgang recommened. I migrated old syntax to new one and replace \page[yes] before each section to \setupheads[section][style={\bf \ssc}, alternative=margin, page=yes] but now after each section there is a new page. Why? I don't know. Can someone help me to see what happens? The source code is here [https://repo.or.cz/apunts-espa-matematiques.git] Thanks in advance, Xavier PS: Please CCme

Better option for a macro with lots of arguments
by Andres Conrado Montoya 23 Aug '23

23 Aug '23

I have been using the following macro to add a bunch of sections to the start of chapters in a book, it works but I think is kind of weak: %%%%%%%%%%%%%%%%%%% \define[7]\metadatos{ \startsection[title={Resumen}] #1 \stopsection \startsection[title={Palabras clave}] #2 \stopsection \start \language[en] \startsection[title={Abstract}] #3 \stopsection \startsection[title={Keywords}] #4 \stopsection \stop \startsection[title={¿Cómo citar este capítulo? / How to cite this book?}] \startsubsection[title={Apa}] #5 \stopsubsection \startsubsection[title={Chicago}] #6 \stopsubsection \startsubsection[title={MLA}] #7 \stopsubsection \stopsection } \starttext % Then I call the macro like this: \metadatos{spanish abstract \input knuth}{some, comma, separated, keywords, in, spanish}{english abstract \input knuth}{same, comma, separated, keywords, in, english}{Apa citation style for this article}{Chicago citation style for this article}{MLA citation style for this article} \stoptext %%%%%%%%%%%%%%%%%%% I've been exploring different ways to do it better, but with not much luck, I was thinking something based in key=value assignments? setups? datasets? Not really sure, but If you know a better solution or point me in the direction of something I can use to replace that macro, it would be greatly appreciated. -- 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.
