Export, page break markers
by Denis Maier 14 Oct '20

14 Oct '20

Hi, as I'm almost done with my PDFs for the first volume of our journal, I'm thinking about also publishing HTMLs. We have XSLTs almost ready for this, but I was thinking if I could use ConTeXt also for this. A very nice feature would be being able to add marking of page breaks in the resulting XML/HTML. The wiki says it's not possible, but I'm not so sure this page still reflects the current state of affairs. Is that possible by now? Other export related things that have changed in the last three years? Best, Denis

Consequences of \zwnj for hyphenation
by Denis Maier 14 Oct '20

14 Oct '20

Hi, has \zwnj (or the equivalent unicode character) bad consequences for hyphenation? Like, when you'd preprocess your files and add \zwnj in appropriate places, will that break hyphenation for these words? Best, Denis

index issues
by Henning Hraban Ramm 14 Oct '20

14 Oct '20

(1) If I get the same index entry two or more times on a page, sometimes with processor formatting, sometimes not, how can I control which version takes precedence? Actual use case: index entries from footnotes should be italics, while those from the main text stay upright. Now, if there is an entry from the main text, the entry from the footnote doesn’t matter. Is it possible to control that? I wouldn’t like to sort out the cases manually and remove the entries from the footnotes – there are 981 footnotes in this book, and there are 15 pages of index entries. I’m using a macro (I suppose you’ll remember; I left out the Lua table lookup for unified entries): \defineprocessor[kursiv][style=italicface] \define[1]\nIndex{\doifmodeelse{*footnote}{% \expanded{\index[kursiv->]{#1}}}% }{% \expanded{\index{#1}}}% }} (2) Can I avoid linebreaking of page ranges in \placeindex? E.g. in Knuth, Don 23, 35- 37, 40 I’d like to keep 35–37 together (break before 35). Hraban

How do you deal with inappropriate ligatures?
by Denis Maier 14 Oct '20

14 Oct '20

Hi, with LuaLaTeX I used to use the selnolig package to disable inappropriate ligatures. With ConTeXt I have just inputted the list prepared by Hraban (based on a wordlist originating from selnolig), but then ran into a curious bug (?) with disappearing characters (see my posts from a couple of days ago). I'm now converting this list to the \blockligatures mechanism (instead of using \replaceword), which also has better kerning support due to Hans. When done, I'll of course share this on the Wiki if there's any need for this. Now I'm wondering how others deal with inappropriate ligatures. Do you just ignore them? Do you block them on an ad-hoc basis, like whenever they occur? Do you use scripts to pre-process your files before typesetting? Do you just disable ligatures globally? I tend to think there must be an automatic way to deal with the most awkward cases. The problem is that there just so many. What do you think? Best, Denis

need help comparing strings
by Pablo Rodriguez 13 Oct '20

13 Oct '20

Dear list, I have the following sample: \starttext \def\numbersfname {\cldcontext{string.match([[\env{fname}]], "\letterpercent d+")}} \ctxlua{ c = context.getvariable("environment", "fname") or "a" } \ctxlua{ d = [[\env{fname}]] } tex: \numbersfname\\ \doifelse{} {123}{yes}{no}\\ c: \cldcontext{c}\\ \doifelse{\cldcontext{c:match("\letterpercent d+")}} {123}{yes}{no}\\ d: \cldcontext{d}\\ \doifelse{\cldcontext{d:match("\letterpercent d+")}} {123}{yes}{no} \stoptext For compilation, I run the command: context --purgeall --arguments=fname={abc123} test-file.tex These things are failing: 1. I don’t know how to get \numbersfname equal to "123". I don’t know what I’m doing wrong. 2. Is there no Lua version of \getvariable{...}{...}? 3. I’m trying this on a Linux box, but on Windows I would say that Lua variable "d" is empty. I need to get the number from \env{fname} and I don’t know what I’m missing. \doif is the way to test whether it’s right. Could anyone explain me what I’m missing here? Many thanks, Pablo -- http://www.ousia.tk

bug with hz in LMTX?
by Pablo Rodriguez 13 Oct '20

13 Oct '20

Dear list, I have the following sample: \showframe\showgrid \setuplayout[width=middle] \definefontfamily[mainface][rm][TeX Gyre Pagella] [features={default, quality}] \setupbodyfont[mainface, 20pt] \setupalign[hanging, hz] \starttext \dorecurse{25}{\input{zapf}\input{cuomo}} \stoptext On page 36 (https://pdf.ousia.tk/wrong-font-expansion.pdf#page=36) lines 4, 11 and 20 are wrong. Current LMTX (LuaTeX 2.07 20200920 + ConTeXt MkIV 2020.09.20 23:02) has the issue, while MkIV (LuaTeX 1.11 7226 + ConTeXt MkIV 2020.01.30 14:13) has no problem with that. I think this might be a bug. Could you confirm the issue? Many thanks for your help, Pablo -- http://www.ousia.tk

font clarification
by jbf 13 Oct '20

13 Oct '20

Can someone clarify a font issue for me please. I have the following setup: \definefontfamily[mainface][rm][TeX Gyre Pagella] \definefontfamily [mainface] [ss] [Arial][tf=file:arial:ttf] \definefontfamily [mainface] [mm] [TeX Gyre Pagella Math] \setupbodyfont[mainface,11.5pt] When I look at what this produces, I see that my body text is in fact texgyrepagellamath-regular. If I run mtxrun --script font --list --file -pattern=*pag*, I see, among others, the following: texgyrepagellamath ... texgyrepagellamathregular texgyrepagella-math.otf conflict: regular texgyrepagella ... texgyrepagellaregular texgyrepagella-regular.otf conflict: regular So three questions: 1. Does Tex Gyre Pagella Math contain everything I need for my body font (ignore Arial - I use that for drop caps and a few other things and it works as it should)? 2. If so, do I still need the first line in my setup, namely the [rm] line? Would not the [mm] be enough? 3. The mtxrun output suggests there is a 'conflict' between tgpagella-regular and tgpagella-math. What is the nature of this 'conflict'? It is possible that my questions reveal a basic misunderstanding of this typeface. Don't hesitate to tell me so but also try to put me right. Julian

figure library
by Jörg Hagmann 12 Oct '20

12 Oct '20

I have used figure libraries in the mkII past. But my recent attempts with mkIV, following the instructions on ConTeXt Wiki (https://wiki.contextgarden.net/Image_Database) have failed. The following happens: 1. When running the command "context --input=figure-lib.xml auto:x-res-01.mkiv --result=figure-lib" in an EMPTY directory, 2 pages with buttons and titles are created. 2. When providing an image and an xml file (copied from the website above and including the image name and the missing ">" at the end), these are ignored -- the same 2 empty pages are created. Could somebody tell me what's wrong (with me, most likely)? Details: mkiV and LMTX, MacOS and FreeBSD, recent ConTeXt installations.
