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)

LuaTeX finds font, mtxrun --fonts does not list it?
by Sandra Snan 30 May '16

30 May '16

I'm trying to add a ttf font (Futura) so I can use it in ConTeXt. I've ran mtxrun --script fonts --list --all |less looked at a ttf font that was there, copied my Futura ttfs to the same directory it was in, and ran mtxrun --script fonts --reload --force But I still can't find it in mtxrun --script fonts --list --all |less nor can I use it in ConTeXt. (The filenames don't have spaces.) The curious thing is that the luatex cache has it. It's listed in /home/sandra/.texmf-var/luatex-cache/generic/names/luaotfload-names.luc under various names, all starting with "futuralt". Curiously, /home/sandra/.texmf-var/luatex-cache/context/[number]/fonts/otf/futuralt-book.tm[ac] exist. But the only "book-" related name in luaotfload-names.luc is futuraltbook, not futuralt-book. Neither worked in ConTeXt, though. How do I move forward with this, how do I add ttfs so that ConTeXt understand them? Sandra

Adjusting Kerning/Spacing between Letter
by Malte Stien 27 May '16

27 May '16

Hi, I am trying to typeset some strings in {\tt ...}, but they turn out to be pretty wide. So, I would like to compress those bits of text a little. Any hints on how I could do that locally, that is without adjusting the entire font. Thank you, Malte.

Support for Optional Content Groups
by Chris Chapman 22 May '16

22 May '16

I am new to ConTeXt (coming from LaTeX), and am really impressed. Great work! I am working on a document that has layers that I want to be screen-only, similar in approach to this: http://tex.stackexchange.com/questions/167846/implementing-full-page-screen… I am assuming that Optional Content Groups would be the best way to do this. How would I set something up like this in ConTeXt/LuaTeX? I know I could make a screen-only version and a print version of the output pdf, but I want to have my cake and eat it too ;) Thanks in advance, Chris Chapman

new features
by Hans Hagen 22 May '16

22 May '16

Hi, (mostly for Thomas) In the next beta: When you include files in another file (using xmlinclude) we now register what gets included. There are two new commands: \xmlinclusion{#1} : the current inclusion \xmlinclusions{#1} : a list of inclusions the first one backtracks till it find a name and the second one will locate the root if needed. This option can be handy for tracing (i.e. seeing where input comes from). Another addition is that \definemode[something][keep] define an undefined mode; the keep makes sure that the already set value is kept (another option is 'yes'). Using defined modes (that is, set with: \enabledmode, \disablemode or \definemode) can be tested about twice as fast as undefined modes which can make a small difference when modes are tested lots of times.

bibliography tool
by Gour 22 May '16

22 May '16

I was browsing docs in the contextgarden but not sure what is available for handling bibliography in ConTeXt today? Afaict, RefTeX is for LaTeX only, I recall there was(is). (My dev environment is Debian Linux/Emacs/AUCTeX.) Sincerely, Gour -- Whatever action a great man performs, common men follow. And whatever standards he sets by exemplary acts, all the world pursues.

halign broken
by Meer, H. van der 16 May '16

16 May '16

There seems something very much amiss with \halign in later ConTeXt versions. This typesets fine in PlainTeX and is an example taken from a textbook. \tabskip=1em\halign{% \hfil\it#\hfil&\hfil#\hfil&#&\hfil#\crA&B&C&D\cr} Also in contextversion 2012.05.30 (from a TeXlive distribution). But it fails at least in ConTeXt ver: 2013.03.20 10:34 MKIV and in ConTeXt ver: 2013.04.16 12:08 MKIV beta with the following error ! Only one # is allowed per tab. system > tex > error on line 5 in file fixedwidth.tex: Only one # is allowed per tab ... 1 \starttext 2 contextversion=\contextversion\par 3 \tabskip=1em 4 \halign{% 5 >> \hfil\it#\hfil&\hfil#\hfil&#&\hfil#\cr 6 A&B&C&D\cr} 7 \stoptext l.5 \hfil\it#\hfil&\hfil# \hfil&#&\hfil#\cr Why? How primitive it may be, I would like to use \halign now and then. Hans van der Meer
