How to get the current section level?
by Lukáš Procházka 04 Apr '16

04 Apr '16

Hello, is there a (Lua) way how to get the current section level? Something like: ---- \def\GetCurrentSectionLevel{% % What to come here? } \starttext \chapter{Ch} \GetCurrentSectionLevel % Should yield "chapter" or e.g. 1 (meaning "chapter") \section{Sec} \GetCurrentSectionLevel % Should yield "section" or e.g. 2 (meaning "section") \subsubsection{SSSec} \GetCurrentSectionLevel % Should yield "subsubsection" or e.g. 4 (meaning "subsubsection") \stoptext ---- Best regards, Lukas -- Ing.

deprecated startMPenvironment
by Meer, Hans van der 04 Apr '16

04 Apr '16

Previously I could do the following \starttext \startMPenvironment[+]\switchtobodyfont[small]\stopMPenvironment \startMPpage % metafont code \stopMPpage \stoptext \endinput This is called by context --run --once etc. producing the figure and in this case modifying the font to a smaller size. Note, the context call occurs on the fly inside a \directlua{{os.execute(..)}. You may find this complicated, but it works for me and I would rather like not having to change may things all over the place. Now I learn from the ConTeXtgarden that startMPenvironment is deprecated and that I should use defineMPinstance and setupMPinstance instead. Thus I tried \defineMPinstance[mp:local][metafun][setups=mp:smallfont,textcolor=red] \startsetups mp:smallfont \switchtobodyfont[small] \stopsetups \startMPpage and also \startMPpage[mp:local] % metafont code \stopMPpage \stoptext \endinput But nothing happens. How do I get the effect earlier obtained with startMPenvironment without having to rely an a deprecated macro? Hans van der Meer

Server down

Hi, For reasons unknown to me the contextgarden.net server is currently down. The wiki (and some other components hosted at Taco's server) are still working. I have to wait until the network admin looks into the problem. I'm really sorry for the inconvenience, Mojca

Margin text running off bottom of page
by Robert Krug 03 Apr '16

03 Apr '16

Greetings, Is there any way to prevent marginal text from running off the bottom ot the page? I can adjust the margin widths to prevent them from running off the edges, but I cannot figure out how to do the same for the bottom of the page. \starttext text. \vskip 7.5in text \margintext{The book I am working with has marginal annotations that act as a précis of the argument in the main text. Some of them are several sentances long.} text. \stoptext Robert

Dear Hans and listers, I am sorry that I didn’t read another series of mails about “skipped figure numbers”. Please ignore my previous mail. Thank you. Best regards, Dalyoung

Dear Hans, Your sample works fine. This method gives me a flexibility of combining figures. BTW, I have one question. In the output, figure numbers started from 3, but suddenly jumped to 184. In a log file, metapost > initializing number mode 'scaled' floatblocks > '3' placed floatblocks > '4' placed floatblocks > '5' placed floatblocks > '6' placed floatblocks > '7' placed floatblocks > '8' placed floatblocks > '9' placed floatblocks > '10' placed floatblocks > '11' placed … floatblocks > '241' placed floatblocks > '242' placed floatblocks > '243' placed backend > xmp > using file '/Users/graph/ConTeXt/tex/texmf-context/tex/context/base/mkiv/lpdf-pdx.xml' pages > flushing realpage 1, userpage 1 pages > flushing realpage 2, userpage 2 pages > flushing realpage 3, userpage 3 pages > flushing realpage 4, userpage 4 pages > flushing realpage 5, userpage 5 pages > flushing realpage 6, userpage 6 pages > flushing realpage 7, userpage 7 pages > flushing realpage 8, userpage 8 pages > flushing realpage 9, userpage 9 pages > flushing realpage 10, userpage 10 pages > flushing realpage 11, userpage 11 I just curious why the number started from 3, and where are the numbers 4 - 182 omitted. Is there any other meaning? Thank you. Best regards, Dalyoung

The \leftboundary command uses a new LuaTeX primitive which means you can’t find it in a TeX [1] reference. spac-ver.mkiv: \unexpanded\def\leftboundary {\boundary\plusone} \unexpanded\def\rightboundary {\boundary\plustwo} Wolfgang

WIKI - broken links to source files
by Jan Tosovsky 01 Apr '16

01 Apr '16

Dear All, there are broken links on several WIKI pages... In e.g. http://wiki.contextgarden.net/Protrusion there is http://source.contextgarden.net/font-ext.lua instead of proper one http://source.contextgarden.net/tex/context/base/font-ext.lua But when the latter link is clicked, instead of displaying the content I am getting: Internal Error - please restart the application! Links to MkII source I couldn't locate at all. A side note. Would it be possible to somehow grab Wiki content and verify if such links to TEX or LUA files exists? Thanks, Jan
