Dear list, I have the following sample: \starttext \startitemize[\ifnum\currentnofitems>5 packed\fi] \dorecurse{7} {\startitem\currentitemnumber/\currentnofitems\stopitem} \stopitemize \stoptext Is there any way to get a packed list if and only if it contains more than a given number of items? Many thanks for your help, Pablo -- http://www.ousia.tk

MKIV: error, no format found with name: cont-en, aborting
by luigi scarso 14 Nov '19

sent from context(a)rik.users.panix.com Note from admin: the email is in defer state because "Message body is too big: 159549 bytes with a limit of 100 KB" I have kept the initial part. """"" Dear list, Since the 20191029 update I have not been able to create a document via MKIV, suffering from the subject error message (error, no format found with name: cont-en, aborting). I have tried cache clearing, regeneration, and complete fresh installs. None work. I suspect it is something on my system, but cannot think of a relevant change except possibly a Win10-64 system update. Attached is the log from the latest install try (with filenames of copied files removed). LMTX has no problems. All suggestions welcome. -- Rik Kabel """"""

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.

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
