SOLVED: too many open files
by Henning Hraban Ramm 19 Jun '16

19 Jun '16

Hi again, in my current songbook project I use t-filter with LilyPond as shown in http://wiki.contextgarden.net/LilyPond with latest beta MkIV on OSX. Every line (system) of notes is included as its own PDF to leave the page breaking to ConTeXt. But since I have some hundred songs with each a few lines, it sums up... I guess ConTeXt keeps every externalfigure open, since I get this error: pages > flushing realpage 70, userpage 70 (c_helpmesee.tex structure > sectioning > TitelKlein @ level 2 : 0.83 -> Help Me See GNU LilyPond 2.16.2 ERROR: In procedure open-file: ERROR: Too many open files: "/Applications/music/LilyPond.app/Contents/Resources/bin/../share/guile/1.8/ice-9/r4rs.scm" LILYPOND > name='lilytemp/prd_alle-temp-lilypond-c_helpmesee.pdf' LILYPOND > including system no.1 LILYPOND > including system no.2 LILYPOND > including system no.3 LILYPOND > including system no.4 LILYPOND > including system no.5 ) (c_hochaufdem.tex </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-1.pdf> </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-2.pdf> </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-3.pdf> </Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-4.pdfI/O Error: Couldn't open file '/Users/hraban/workspace/liederheft/lilytemp/prd_alle-temp-lilypond-c_helpmesee-4.pdf': Too many open files. !LuaTeX error: xpdf: reading PDF image failed ==> Fatal error occurred, no output PDF file produced! It works with songbook excerpts (some 30 songs). I don't understand if the error is really from LilyPond or from LuaTeX (I guess the former), and how I would be able to increase the number of possible files (in bash on OSX 10.8.4). So probably it's more a general Unix question than a ConTeXt one, but anyway... ANALYSIS: $ ulimit -n 256 $ sysctl kern.maxfiles kern.maxfiles: 12288 $ sysctl kern.maxfilesperproc kern.maxfilesperproc: 10240 SOLUTION: $ ulimit -S -n 2048 (Properly describing a problem often helps to solve it. I send this for the records, in case someone runs into the same.) Greetlings, Hraban --- http://www.fiee.net/texnique/ http://wiki.contextgarden.net https://www.cacert.org (I'm an assurer)

Execute ConTeXt script from outside a project's directory
by Nicola 19 Jun '16

19 Jun '16

Hello, I am looking for a way to run ConTeXt from an arbitrary (Unix) directory. I have tried with --path: cd / mtxrun --path /My/Project/Directory --script context main.tex but that just prints a path and exits: /Applications/ConTeXt-Beta/tex/texmf-context/scripts/context/stubs/unix/context Is there a way to specify a project's directory?

[NTG-ConTeXt] Wrong order of sections and subsections
by Marcus Vinicius Mesquita 19 Jun '16

19 Jun '16

Dear List In the wiki, http://wiki.contextgarden.net/Titles, there is a MWE of how to flush section head data without typesetting it in the text. But then \placelist gives a wrong order of sections and subsections: 1 First section 1.1 First subsection 2 Second section 1.2 Second subsection 2.1 First subsection If \setuptexttexts is omitted and the argument placehead=yes instead of placehead=hidden, then the order is correct: 1 First section 1.1 First subsection 1.2 Second subsection 2 Second section 2.1 First subsection Am I missing something?

enumeration header spacing control

Dear members, In the MWE below the amount of vertical space between the enumeration header and the text seems to fully controlled by the global \setupwhitespace setting.

Flushleft formula
by Aditya Mahajan 18 Jun '16

18 Jun '16

Hi, Something has changed with respect to the align=flushleft option for formulas. Earlier (tested with 2016.05.08), align=flushleft did not remove the leftskip, but now it does. Consider the following example: \showframe \setupitemize[margin=6em] \setupformula[align=flushleft] \starttext \startitemize \item An equation inside an itemize \startformula E = mc^2 \stopformula \stopitemize \stoptext The output of 2016.05.06 is attached as test-old.pdf; that of 2016.06.16 is attached as test-new.pdf Is it possible to revert to the old behavior? Thanks, Aditya

Orphans and widows for specific paragraph groups
by Pavneet Arora 17 Jun '16

17 Jun '16

I have a couple of questions about preventing orphans for specific document blocks. These all relate to a web-based report card application I have written for a study abroad school client of mine. The ConTeXt file is being generated and processed out of a PHP Laravel framework app. I have stripped away most of the details as well as the application fonts, but the issue that I am facing is related to keeping the course header (done as a paragraph environment), \hairline, and the teacher's comment for that course together as a unit. At a minimum, I would like the three elements as a grouped and pushed to the following page. Ideally, and this is more for my own learning, I'd like to be able to have finer control---say the header, \hairline, and a set number of comment lines would be acceptable at the bottom of a page. What would be the best practices for this? advTHANKSance >>>> MWE \definefontfamily[mainface][rm][Latin Modern Roman] \definefontfamily[mainface][ss][Latin Modern Sans] \definefontfamily[mainface][tt][Latin Modern Typewriter] \definefontfamily[mainface][mm][Latin Modern Math] \setupbodyfont[mainface,9pt] % Set up default paragraph indenting and spacing. \setupindenting[yes, medium, next] \setupwhitespace[small] % Set up paragraph environment for subject header. \defineparagraphs [subjectpar][ n=2, before={\blank[2*big]}] \setupparagraphs [subjectpar] [1] [width=.3\textwidth] \starttext \blank[8*big, force] \dorecurse{10}{ \blank[2*big] \noindentation \startsubjectpar {\ss\tfc ENG4U} \subjectpar %% Need to keep the following together as a unit. {\ss\tfc English (Grade 12)} \stopsubjectpar \noindentation \vskip-2em\hairline \setupindenting[yes, medium, next] \dorecurse{1}{ \input lorem.tex } } \stoptext <<<< MWE -- Pavneet Arora m: +1 (647) 406-6843 Waroc Informatik t: +1 (416) 937-9276

Re: [NTG-context] Invoking ConTeXt from inside php web appliction
by Pavneet Arora 17 Jun '16

17 Jun '16

Ah, we were thinking along the same lines! ;) I had just initiated a local install inside .../www/public when I received your email, which is in fact the DocumentRoot for this website, and did: $ chmod -R www-data:www-data context So ConTeXt is installed in .../www/public/context. Now I can source: $ . .../www/public/context/tex/setuptex .../www/public/context/tex and it all works. Many thanks, Luigi, for all of your suggestions.

Latin setupmathematics
by Hans Åberg 17 Jun '16

17 Jun '16

In order to align with Unicode, \setupmathematics might have Latin shape options, as the Greek ‘lcgreek’ and ‘ucgreek', say ‘lclatin' and ‘uclatin', both defaulting to ’italic’. Unicode added the Latin italic symbols to the Math Alphanumeric Symbols range, so the upright letters are inaccessible when italic is assigned to the Basic Latin (ASCII) range.
