Itemization formatting
by Taco Hoekwater 29 May '19

29 May '19

Hi all, I must be getting old :( It used to be that I could get ConTeXt to do what I wanted, but that is increasingly getting harder. Current problem: I would like to have itemizations that behave like in this dummy ascii formatting: * Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec dapibus turpis et nulla venenatis tincidunt. Curabitur sit amet vehicula nisi, sit amet and so far it has been impossible for me to set up \setupitemize to do what I want. In descriptive text, what I want is: 1. some global indentation to the left and/or right. That is what the margin= key does 2. the symbol (or number) typeset in a specific width. That is the width= key 3. some distance between the number box and the following text. That is the distance= key 4. on line 2 and forward to the end of the item, I want a *different* indentation from the first item line. In this particular case, I want no extra indentation except for ‘margin’, but in other cases I may like either more or less indentation than on line 1 of the first para of the item. The desired effect is simple achieve with primitive operations, but I would like the input to look nice (not to mention that I do not want to loose options for cross-referencing etc). \setupitemize[option=intext] is nearly right for this case (with indentation equal to the left margin), so I assumed I would be able to tweak that. But the problem there is that while it does 2-4, it ignores the extra indentation required for nested itemizations (it even ignores explicit margin= settings for the nested level). After fighting with this for hours, I am nearly ready to give up. Anybody have any idea how to get itemizations to do what I want? MWE attached. Best wishes, Taco PS It seems that “indentnext=no” does not work for nested itemizations?

bookmark expansion again
by Pablo Rodriguez 28 May '19

28 May '19

Hi Hans, I have the following sample: \def\eap{expansion} \def\MyContent{Expanded \eap} %~ \enabledirectives[references.bookmarks.preroll] \setupinteraction[state=start, title={\MyContent}] \placebookmarks[section] \starttext \section{\MyContent} \startsection[title=\MyContent, bookmark=\MyContent] \stopsection \stoptext I see that now PDF contents are prerolled by default (which I think it is a great idea [I hope it isn’t a bug]). But bookmarks alone (when aren’t prerolled. From strc-sec.mkiv, I see that prerolling is only applied to \currentstructuretitle when \currentstructurebookmark is empty. Would it be possible that \currentstructurebookmark could have prerolling when it is different from \currentstructuretitle? Sorry for insisting, but I need this to avoid having "main:345{/h2}" as bookmark for some chapters. Many thanks for your help, Pablo -- http://www.ousia.tk

two (2) questions about footnotes
by Thomas A. Schmitz 27 May '19

27 May '19

Hi all, I have two questions/problems about footnotes. Here is a minimal example, which does not compile in this form: \unexpanded\def\MyRule{\blackrule[width=\textwidth,height=3pt]} \setupfootnotes[rule=\MyRule] \starttext Test1: \index{Adam}Adam.\footnote{Test2: \index{Eve}Eve.} \page \placeregister [index] \stoptext (1) In my current project, the publisher wants the rule separating text and notes to extend across the entire text width. I found the \blackrule command and its use in the setup on the mailing list, many years ago, proposed by Steffen Wolfrum, but it doesn't work (anymore?); I get "tex error on line 3 in file /tmp/test.tex: ! Missing \endcsname inserted." Any hints? (2) Again, something that has been asked on the mailing list, but not received any replies: would it be possible to have the index report that "Eve" occurs inside a footnote? So it says "Eve 1 n. 1" or something like that? Thanks a lot, and all best Thomas

Fontloader
by Herbert Voss 26 May '19

26 May '19

I had a problem with the fontloader and luatex. I tried to run my test document with context (latest minimal) to compare the output, but I failed. The font LibertinusKeyboard-Regular.otf https://ctan.org/tex-archive/fonts/libertinus-fonts/ uses ligatures especially for the keys above 0xFFFF However, I cannot get it run with latest mkiv. It is no problem with xetex. It should print only the five keys and not the ones for every single letter. Herbert \font\keyboard=LibertinusKeyboard-Regular.otf \starttext \keyboard Tab Entf Enter Capslock Windows \stoptext

Typesetting Markdown
by Thangalin 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

https://wiki.contextgarden.net/Fraktur_fonts
by Rudolf Bahr 23 May '19

23 May '19

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.
