Typesetting Markdown
by Thangalin 26 May '19

26 May '19

Hi folks! I'm thinking about writing a series of blog posts about how to typeset Markdown using ConTeXt. I've written the first part and am wondering if anyone would be interested in reading more: https://dave.autonoma.ca/blog/2019/05/22/typesetting-markdown-part-1/ Thank you!

no bookmark prerollling in bookmark option
by Pablo Rodriguez 23 May '19

23 May '19

Dear list, I have the following sample: \def\MyContent{This is expanded content} \enabledirectives[references.bookmarks.preroll] \setupinteraction[state=start, title={\MyContent}] \placebookmarks[section] \starttext \section{\MyContent} \startsection[title=\MyContent] \stopsection \startsection[title=\MyContent, bookmark=\MyContent] \stopsection \stoptext Bookmarks aren’t prerolled when the bookmark option from \startSECTION is used. I think it may be a bug. Could anyone confirm it? Many thanks for your help, Pablo -- http://www.ousia.tk

Hello All, I wrote the wiki page "https://wiki.contextgarden.net/Fraktur_fonts" on my experiences of ConTeXt and three Fraktur fonts. 4 result images are still missing. I didn't succeed in uploading them to the server in reasonable time. Could somebody, who has already uploaded images, please, do it for me? The 4 images are appended here. Best wishes, Rudolf

Even with my scanner software I produce always .jpg-images though it is capable to produce .pdf-output too. The only .pdf-files I'm doing are made by ConTeXt-LMTX! I shall append another, interesting MWE. There is a .png-image which is, as it occasionally happens, represented as it should, by ConTeXt. And then the same .png-image to which I added a red frame by GIMP2.10. This one shows artefacts in ConTeXt! I'm adding the .log-file too. There again is a luatex-warning, as I could observe them often in ConTeXt-LMTX: ------------------------------------------------------------- luatex warning > pdfe: invalid 11 0 R object at offset 41603 ------------------------------------------------------------- Please, what does mean it? I fear there is something wrong with the .png-handling of ConTeXt/luatex. The outputs of feh image----red-frame.png gm display image----red-frame.png are looking ok. And GIMP2.10 has produced all image-files.

XML export: basic questions
by Procházka Lukáš Ing. 22 May '19

22 May '19

Hello, suppose having "Main.mkiv": ---- \setupbackend[export=yes] \starttext \startsection[title={Sec},MyPar=MyVal] \input knuth \stopsection \stoptext ---- Some questions concerning XML export: 1. Normally, with \setupbackend[export=yes], Ctx creates "Main-export" directory containing (among others) Main-raw.xml, and Main-tag.xhtml and some subdirs. Is there a way to tell Ctx to produce just one XML file with a prescribed name which wouldn't be placed in any subdir? In my case - to produce "Main.xml" (instead of "Main-export/Main-raw.xml"), other files to be omitted? 2. Is there a way to export user parameters used in \section? In my case: \startsection[title={Sec},MyPar=MyVal] uses user parameter "MyPar" with value "MyVal", but "MyPar" is not transmitted into XML; the goal is to have <section detail="section" chain="section" implicit="1" level="3" MyPar="MyVal" > which would allow some filtering when reprocessing that XML. - Or is there another way, like enclosing into a user tag: \starttag[MyTag] \startsection[title={Sec},MyPar=MyVal] \input knuth \stopsection \stoptag which would export into: <MyTag> <section detail="section" chain="section" implicit="1" level="3" MyPar="MyVal"> ... </section> </MyTag> Best regards, Lukas -- Ing.

section to have different conversion in body part and appendices
by Procházka Lukáš Ing. 22 May '19

22 May '19

Hello, is there a way to tell \section (or other heads) to be "number-converted" differently in bodypart and appendices? Something like: ---- \setuphead[section][] % e.g. "appendices:numberconversion=A"? \starttext \starbodyamtter \section{In body} % To produce "1. In body" \stopbodymatter \startappendices \section{In apps} % To produce "A In apps" \stopappendices \stoptext ---- Best regards, Lukas -- Ing.

UTF8 chars in attribute values (XML)
by Pablo Rodriguez 21 May '19

21 May '19

Hi Hans, I’m afraid I found another issue with UTF8 chars in attribute values when printing them. \starttext \startTEXpage[offset=1em] \startXML <tag value="aä" /> \stopXML \stopTEXpage \stoptext Inspecting buff-imp-xml.lua, I understand that "alsoname" should be added to "key". But I don’t know where or how this could be achieved. Sorry for not providing a patch, Pablo -- http://www.ousia.tk

problem with UTF8 chars in XML elements
by Pablo Rodriguez 19 May '19

Dear list, I have the following sample: \startbuffer[demo] <?xml version="1.0" encoding="UTF-8"?> <doc> <título>Title</título> </doc> \stopbuffer \startxmlsetups xml:sample \xmlsetsetup{#1}{doc|título}{xml:*} \stopxmlsetups \xmlregistersetup{xml:sample} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:título \title{\xmlflush{#1}} \stopxmlsetups \starttext \xmlprocessbuffer{main}{demo}{} \stoptext ConTeXt has problems parsing <título>. To the best of my knowledge, this is a valid XML element name (sorry, but I don’t have a better reference: https://en.wikipedia.org/wiki/XML#International_use] How can I get this parsed with ConTeXt?
