Setting expansion depth limit for metapost
by Michal Suszko 18 Feb '16

18 Feb '16

I'm preparing quite long presentation -- nearly 3000 sides, 900 figures (500 distinct PNG files). I'm using ConTeXt MkIV installed using minimals (2010.03.12 19:49). Recently I'm hitting MetaPost capacity limit on expansion depth: !mplib : mp terminal: ! MetaPost capacity exceeded, sorry [expansion depth=10000]. Increasing expand_depth in texmf.cnf and regenerating formats with context --make doesn't help. expansion depth is still at 10000 in error message. texmf.cnf in texmf-local I've changed is reported by context as first one in log line starting with "mkiv lua stats : used config path" What am I missing?

Overfull boxes using m-cweb
by Edwin Wisse 27 Jan '16

27 Jan '16

Hello, I am running into overfull boxes when including a weaved cweb file into a context document. The original reference to the cwebmac.tex file (the plain TeX macro) is commented out and replaced by \usemodule[cweb]. The cweb macros appear to expand something into \*11ptmmmt* which seems to have something to do with it. Is there anyone here with experience and deep (Con)TeX(t) knowledge who understands what is happening? Regards, Edwin ----------------------------------part of my log file------------------------------------------------ Overfull \hbox (6.4885pt too wide) in paragraph at lines 3--13 \*11ptmmmr* for the ap-pli-ca-tion de-vel-op-ment mod-ule.

next beta
by Hans Hagen 16 Apr '15

16 Apr '15

Hi The next beta will have this (I needed it for a manual): \starttext \starttabulate[||CL{darkred}|CM{darkgreen}CT{white}|CR{darkblue}||] \NC first \NC left \NC middle \NC right \NC last \NC \NR \NC first \NC \color[white]{left} \NC middle \NC \color[white]{right} \NC last \NC \NR \NC first \NC left \NC middle \NC right \NC last \NC \NR \stoptabulate \stoptext i.e. we already had CL CM and CR, so CT is new .. should be wikified.

Steps in presentation
by pol stra 03 Jan '15

03 Jan '15

Hello, I tried to use some steps in a presentation. In the following conversation http://www.mail-archive.com/ntg-context@ntg.nl/msg53524.html, Wolfgang says that we can use the pre-60 module. So I tried this snippet: \usemodule[pre-stepwise] \starttext \StartSteps \startitemize \item one \FlushStep \item two \FlushStep \item three \FlushStep \stopitemize \StopSteps \stoptext But it does not compile: ConTeXt ver: 2012.09.11 20:36 MKIV fmt: 2012.9.12 int: english/english system > cont-new.mkiv loaded (/opt/context-minimals/texmf-context/tex/context/base/cont-new.mkiv system > beware: some patches loaded from cont-new.mkiv ) fonts > latin modern fonts are not preloaded languages > language en is active (pre60.tex resolvers > modules > loaded: 'pre-stepwise' (/opt/context-minimals/texmf-context/tex/context/base/s-pre-60.mkiv fonts > beware: no fonts are loaded yet, using 'lm mono' in box (/opt/context-minimals/texmf-context/tex/context/base/java-imp-stp.mkiv) interactions > javascripts > loaded: library 'stp' metapost > loaded: library 'nav' (/opt/context-minimals/texmf-context/tex/context/base/meta-imp-nav.mkiv)){/opt/context-minimals/texmf-fonts/fonts/map/pdftex/context/mkiv-base.map} fonts > preloading latin modern fonts (second stage) fonts > typescripts > unknown: library 'loc' {/opt/context-minimals/texmf-fonts/fonts/map/dvips/lm/lm-math.map}{/opt/context-minimals/texmf-fonts/fonts/map/dvips/lm/lm-rm.map} fonts > virtual math > unable to resolve name mapsfromchar fonts > fallback modern rm 12pt is loaded !LuaTeX error: There should have been a lua <node> here, not an object with type string! ==> Fatal error occurred, no output PDF file produced! Is there something broken in recent release of conteXt? By the way It seems there is no Rawsteps module anymore but it still is in the wiki. Is there is something like a bugtracker for conteXt, in order to signal when a feature is not working or outdated and signal when it is back (or definitly depreciate)? (it would be a complementary tool for the mailing list)

internal mptopdf converter skips some glyphs in labels
by Sanjoy Mahajan 06 Jun '14

06 Jun '14

The internal mptopdf converter in MkIV omit some glyphs in the labels. Here's a minimal example (test.tex): \starttext \externalfigure[testfig.1][frame=on] \blank \externalfigure[testfig-1.pdf][frame=on] \stoptext And testfig.1 is produced by testfig.mp beginfig(1) label(btex $\Omega$ etex, (0,0)); currentpicture := currentpicture scaled 5; endfig; end Here's testfig.1 to save a step in debugging: %!PS %%BoundingBox: -18 -18 18 18 %%HiResBoundingBox: -17.98805 -17.0195 17.98798 17.0195 %%Creator: MetaPost 1.803 %%CreationDate: 2013.08.09:1612 %%Pages: 1 %*Font: cmr10 49.81323 9.96265 0a:8 %%BeginProlog %%EndProlog %%Page: 1 1 0 0 0 setrgbcolor -17.98805 -17.0195 moveto (\012) cmr10 49.81323 fshow showpage %%EOF Then do: mptopdf testfig.1 context test.tex xpdf test.pdf The first framed box, using the internal mps->pdf conversion, is empty. The second framed go, using the pdf file produced by mptopdf, correctly contains \Omega. With \enabletrackers[graphics.conversion,graphics.inclusion], the log has the following lines, none of which seem to pinpoint the problem: graphics > inclusion > checking conversion of 'testfig.1', fullname 'testfig.1', old format 'mps', new format 'pdf', conversion 'default', resolution 'default' graphics > inclusion > no converter for 'mps' to 'pdf' [MP to PDF] graphics > inclusion > checking conversion of 'testfig-1.pdf', fullname 'testfig-1.pdf', old format 'pdf', new format 'pdf', conversion 'default', resolution 'default' graphics > inclusion > no converter for 'pdf' to 'pdf' graphics > inclusion > new graphic, using hash 'testfig-1.pdf->1->crop->unknown->unknown->unknown->' (Though I don't believe the "no converter for 'mps' to 'pdf'" diagnostic.)

Re: [NTG-context] Hebrew vowel placement in ConTeXt.
by Michael Ash 03 May '14

03 May '14

Thank you. The unicode text looked good (although reversed left-to-right as I sent it) in my sent mail, and it looked perfect (corrected right-to-left) in your response. But it did not look good in the digest email (all the letters were convered to ?'s). Also it's typesetting fine in ConTeXt except for the vowel placement. Any suggestions there? Thank you again.

Euler with fallback
by Aditya Mahajan 03 Mar '14

03 Mar '14

Hi all, This is to announce that the latest beta supports creating virtual math fonts with fallback. The main test case is to use Euler font with missing characters taken from Pagella but the mechanism is general and can be used to replace a specific set of math glyphs from a font. This feature is not extensively tested. As such it will be useful if everyone interested in math fallback mechanism could test this out and report any bugs or inconsistencies. To use this feature you have to use `pagellaovereuler` as your math font. For example, to use Euler with DejaVu fonts, use: \usetypescriptfile[euler] \starttypescript[mainface] \definetypeface[mainface][rm][serif][dejavu] [default] \definetypeface[mainface][ss][sans] [dejavu] [default] \definetypeface[mainface][tt][mono] [dejavu] [default] \definetypeface[mainface][mm][math] [pagellaovereuler][default] \stoptypescript \setupbodyfont[mainface] \appendtoks \rm \to \everymathematics \setupmathematics [lcgreek=normal, ucgreek=normal] There is a built-in typescript `euler-with-pagella` to use `pagellaovereuler` as the math font and `pagella` as the text font. If you are interested in implementing similar fallback mechanisms for other fonts, see type-imp-euler.mkiv and euler-math.lfg for details. Aditya

Commutative diagrams in tikz-cd: for wiki
by Idris Samawi Hamid ادريس سماوي حامد 28 Feb '14

28 Feb '14

Dear gang, With a couple of modifications I got tikz-cd (a package to make commutative diagrams for categories and toposes etc. by Florêncio Neves) working in mkiv: http://texdoc.net/texmf-dist/doc/latex/tikz-cd/tikz-cd-doc.pdf It depends on the tikz module, already supported in mkiv. The tikz-cd module is attached, and here is a sample file: =============== \usemodule[tikz] \usetikzlibrary{commute} \starttext \starttikzcd %[ampersand replacement=\&] A \arrow{rd} \arrow[yshift=0.5ex]{r}{\phi} \& B \\ \& C \stoptikzcd \starttikzcd %[ampersand replacement=\&] A \arrow[yshift=1.5ex]{r} \arrow[yshift=0.0ex]{r} \& B \arrow[xshift=0.7ex]{d} \arrow[xshift=-0.7ex]{d} \\ \& C \stoptikzcd \stoptext =============== A couple of things: 1 I had to comment out line 396 of pgfsys-pdftex.def in the tikz module, or else I'd get an undefined control sequence. It's not needed anyway since that's pdftex. 2 In tikzlibrarycommute.code.tex, line 395 I had to add the option ampersand replacement=\& to avoid a TeX error. So you'll have to use '\&' instead of '&' for matrix arrays. 3 Some LaTeX-specific stuff is commented, and support is added for \starttikzcd \stoptikzcd so we get a ConTeXt environment. I'm hoping someone can volunteer to place this on the wiki, perhaps even set it up on the modules page, with an indication of its proper place in the texmf-modules tree etc. Any other improvements will also be appreciated. Enjoy! Best wishes Idris -- Professor Idris Samawi Hamid Department of Philosophy Colorado State University Fort Collins, CO 80523

underbraces slightly too narrow (with MkIV 2013.05.28)
by Sanjoy Mahajan 15 Feb '14

15 Feb '14

In certain cases, display-mathunderbraces are not quite wide enough. Here's a minimal example: =================== \starttext \placeformula\startformula \underbrace{15\,\tf cm}_{L} \stopformula \stoptext =================== Using 2013.05.28 00:36 MKIV (from vanilla TL2013), the left brace tip starts under the vertical bar of the "1", instead of enclosing the serif as well. The right brace tip ends between the last two tines of the "m", instead of enclosing the whole "m" and its serifs. With 2013.04.09 10:38 MKII, the brace tips extend just slightly beyond the "15 cm", which is better. However, they seem slightly too close. As a test, I ran the comparable plain-TeX file through LuaTeX and PDFTeX. ================== $$ \underbrace{15\,\rm cm}_{L} $$ \bye ================== The gap between the right brace tip and the text is slightly greater (with either LuaTeX or PDFTeX), and it looks right. (With the 2012.05.30 MKIV on live.contextgarden.net, the result is similar to the Lua/PDFTeX versions, though not identical, and also looks reasonable.) -Sanjoy
