Right-to-left Documents
by Marc Trius 14 Nov '19

14 Nov '19

I'm trying to create a two-sided document in an RTL language. I'd like to reverse the margins and the page flow, so that the first page has the binding on the right side, rather than on the left, and the documents display correctly in pdf readers. I posted this question on TeX Stack exchange, and was informed by Wolfgang Schuster that it is currently impossible to do. He suggested that I use \setcounter[realpage][2] to simulate a document that starts with a left page, but warned that this might cause unwanted side effects. Would it be possible to properly implement document-level right to left direction? I am not an expert ConTeXt user, but I would be happy to assist in testing as much as I am able. Thank you, Marc Trius

Referencing equation, missing dot
by Mikael P. Sundqvist 14 Nov '19

14 Nov '19

Hi, The following example used to work. But with an LMTX updated today, the numbering \eqref produces is (11) instead of the expected (1.1). The numbering in the equation itself is fine. Did something change on purpose? /Mikael %%% TEST FILE \definereferenceformat[eqref][left=(,right=)] \starttext \chapter[title=Foo] \placeformula[eq:bar] \startformula 1+1=2 \stopformula We see in \eqref[eq:bar]. \stoptext

PDF layer links
by Philipp A. 13 Nov '19

13 Nov '19

Hi, I asked this question some time ago: https://tex.stackexchange.com/q/354731/2867 Today I found out about viewer layers. Sadly they seem to be buggy in the ConTeXt version in TeXlive 2019.52575 When I compile the following document, the “view” layer seems to gobble up the rest of the document: Hiding it makes “More text” vanish. Also, I don’t know if [state=stop,printable=yes] does what I want, i.e. being visible by default on print media. If not, how to achieve that? Best, Philipp \defineviewerlayer[print][state=stop,printable=yes] \defineviewerlayer[view][state=start,printable=no] \def\viewcolor#1#2{% \startviewerlayer[view]\color[#1]{#2}\stopviewerlayer% \startviewerlayer[print]\llap{#2}\stopviewerlayer% } \starttext Hi! \viewcolor{red}{This is only red on screen}. More text. \stoptext

new beta
by Hans Hagen 13 Nov '19

13 Nov '19

Hi, I uploaded a new beta. Apart from some fixes, the main change in lmtx is that on windows most (a few exceptions) of the mechanisms that interface to the operating system support the internal wide character model which should make the lot more robust for file names, environment variables, command line options etc that (at the tex/lua end utf8) have characters other than ascii. Another improvement in lmtx is support for ancient type 1 fonts (like the type 1 lucidas) but that's more 'being complete' than a 'real need' (when such fonts are used wiping the cache is needed). Both these (lmtx only) patches can have unforseen (by me) side effects but nothing that can't be fixed fast.

error, no format found with name: cont-en, aborting
by Joseph 13 Nov '19

13 Nov '19

Dear list, Since a couple of betas (luatex/MkIV, not LMTX) I see the following error when processing any .tex file: $ contextjit --noconsole --errors some.tex mtx-context | warning: no format found, forcing remake (commandline driven) ….. lots of lines of output error, no format found with name: cont-en, aborting Any hint on what’s wrong with my local setup by any chance? I use first-setup.bat --modules=all --engine=luatex to update standalone ConTeXt. Thanks in advance, Best regards Joseph

\beginBLOCKS and \endBLOCKS do not work in \dorecurse
by Romain Diss 11 Nov '19

11 Nov '19

Hi, I cannot make \beginBLOCKS and \endBLOCKS work in a \dorecurse loop. Is it possible? Here is a minimum non working exemple (from https://wiki.contextgarden.net/Command/defineblock) %% \startdocument \defineblock[question] \hideblocks[question] % We don't want to print blocks where we define them \dorecurse{2}{ \beginquestion[first] To be, or not to be? \endquestion \section{Let's see what blocks we've got.} \useblocks[question] \section{We've seen what blocks we've got. Let's take another look at that first question.} \useblocks[question][first] \beginquestion[last] Mais o\`u sont les neiges d'antan? \endquestion } \stopdocument %% Thank you in advance. Best. -- Romain Diss

Formatting in toc
by Calum MacLeod 11 Nov '19

11 Nov '19

This morning, I realised what I needed to do, and it works. Before \starttext put: \define[2]\hymn{\bf Hymn #1 \hspace[big] \it #2}\par} After \starttext put stuff like \hymn{34}{We three kings} or \hymn{10}{In the bleak midwinter} etc. This does near enough what I am after: creates a template style command, and replicates formatting in toc. No doubt, there might be tweaks or even cleverer ways to improve on my efforts. Thanks to all who took the trouble to read, and consider; and especially Hraban, who took the trouble to offer a suggestion, which inspired me to think more clearly. Thanks, Calum

Help wanted: index with chapter and section numbers
by Otared Kavian 10 Nov '19

10 Nov '19

Hi, In a math text book, I would like to create an index of some material where chapter and section numbers are given instead of a page number. For instance if the result « 3.2.5 Banach Fixed Point Theorem » is stated in section 2 of chapter 3, and is the fifth numbered statement in that section, I would like to create a \myindex command so that adding the command \myindex{Banach Fixed Point Theorem} at that location, I get in the index created by \myindex a line such as Banach Fixed Point Theorem 3.2.5 Is this possible? Best regards and many thanks for any hint: OK
