Using lua with the command line for "macros"
by Kumar Appaiah 14 Oct '13

14 Oct '13

Hi. At the outset, I understand that this is a slight abuse of LuaTeX and this can be done with plain TeX. Nevertheless, I'd like to see if a solution exists for this approach. I'm trying to use Lua with ConTeXt as a macro preprocessor. To be more clear, I have files A.lua, B.lua which define some variables: A.lua: var1 = "something for a" var2 = "something else for a" B.lua: var1 = "something for b" var2 = "something else for b" And, in my ConTeXt file, I would write: … I will get \directlua{tex.print(var1) and \directlua{tex.print(var2)}. … Now, with lualatex, I use the --lua command line option to pass the initial lua file name. However, for context, I've not found a way to do this. Could someone please advise me? Thanks. Kumar -- Kumar Appaiah

Problem with \overrightarrow over BC and CB
by Mikael P. Sundqvist 14 Oct '13

14 Oct '13

Dear all, with the latest beta (and older ones), the following file %%% start test file \definefontfamily [mainface] [serif] [DejaVu Serif] \definefontfamily [mainface] [sans] [DejaVu Sans] \definefontfamily [mainface] [mono] [DejaVu Sans Mono] [feature=none] \definefontfamily [mainface] [math] [TeX Gyre Pagella Math][scale=1.12] \setupbodyfont[mainface] \starttext $ \overrightarrow{AB} \overrightarrow{BA} \overrightarrow{AC} \overrightarrow{CA} \overrightarrow{AD} \overrightarrow{DA} \overrightarrow{BC} \overrightarrow{CB} \overrightarrow{BD} \overrightarrow{DB} \overrightarrow{CD} \overrightarrow{DC} $ \stoptext %%% end test file gives a shorter arrow than expected above BC and CB (but over the other ones it is OK). Is this a bug in the Pagella math font (it looks OK if one comments out the \setupbodyfont[mainface] above)? Can it be fixed? Best regards, Mikael

Hey list, I've noticed a problem typesetting my book using ConTeXt nightly version 2013.10.04. The following code... \placeformula[formula:Limit of Verhulst equation] \startformula \lim_{t\to\infty} P(t) = K. \stopformula ...seems to raise the following error... ! Undefined control sequence. <recently read> \lim_ l.84 \lim_ {t\to\infty} P(t) = K. -- Kip Warner -- Software Engineer OpenPGP encrypted/signed mail preferred http://www.thevertigo.com

broken Czech dates
by Ondřej Hošek 13 Oct '13

13 Oct '13

Hello, the current ConTeXt Standalone contains a bug when attempting to output Czech dates. Minimal example: \mainlanguage[cs] \starttext \currentdate \stoptext Expected output: 13. řijna 2013 Received output: day, ,month, ,year The culprit appears to be a missing comma in the language definition in lang-def.mkiv: \installlanguage [\s!cs] [ % ... \c!rightquotation=\upperrightdoublesixquote, \c!date={\v!day,\fourperemspace,\v!month,\space,\v!year} \s!lefthyphenmin=2, % ... ] Add a comma at the end of the line defining the date format; this appears to fix the problem. As far as I can tell, the definitions of Slovak (sk) and Turkmen (tk) appear to be suffering from the same problem. Cheers, ~~ Ondra Hošek

bug or needs warning documentation
by d.henman 13 Oct '13

13 Oct '13

I found what I consider a bug in startcombination processing. context version used: version: 2013.09.03 16:23 Examples: 1.) Good compilable source and 2.) source that fails The bad thing about this is that one, at least checks and checks syntax for errors and the error in fact is simply a blank line, which doesn't stand out as a syntax error in my mind, expecially when white space is supposed to be ignored by tex/context in usual modes. Has this been noticed before? ---------------- The below works successfully \starttext \placefigure [here,none] [fig: reference tag] {citation text} { \startcombination[1*2] {\externalfigure[test-image.png][width=34mm]}{} {\externalfigure[test-image.png][width=34mm]}{} \stopcombination } \stoptext ---------------- The below fails \starttext \placefigure [here,none] [fig: reference tag] {citation text} { \startcombination[1*2] {\externalfigure[test-image.png][width=34mm]}{} {\externalfigure[test-image.png][width=34mm]}{} \stopcombination } \stoptext ------------------this failure prints out the following in the log file. system > tex > error on line 8 in file /tmp/minexp.mkiv: Missing { inserted ... system > tex > error on line 1 in file /tmp/minexp.mkiv: You can't use ` ... system > tex > error on line 2 in file /tmp/minexp.mkiv: Undefined control sequence ... The control sequence at the end of the top line of your error message was never \def'ed. If you have misspelled it (e.g., `\hobx'), type `I' and the correct spelling (e.g., `I\hbox'). Otherwise just continue, and I'll forget about whatever was undefined. )) ! Emergency stop. system > tex > error on line 0 in file : Emergency stop ... % END

list of useful typescripts.
by john Culleton 13 Oct '13

13 Oct '13

I am seeking to create (or download) a list of useful typescripts. I define useful as those which call upon fonts/typefaces that are actually distributed with texlive. Perhaps this list exists somewhere. If so I would appreciate a pointer. A list of typescripts that is limited to those calling on fonts in the context distribution would be useful if the list described above is not available. Ultimately I wish to winnow down the list to those fonts containing serif typefaces suitable for use in the text of a novel. The font should have at a minimum roman, italic, bold, bold-italic and small caps typefaces. I can if necessary develop this list myself. But I have learned that is better to ask than to reinvent the wheel. All replies appreciated. I will be using MKIV. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html PDF e-book: "Create Book Covers with Scribus" available at http://www.booklocker.com/books/4055.html
