Dear list, I have problems with \big, \bigl, \Bigl, ... %% Example \def\foo#1{\type{#1}: #1} \starttext \foo{$|x|^n$} % as expected. \foo{$\bigl|x^n\bigr|$} % expect bigger bars \foo{$\big|x^n\big|$} % expect bigger bars \foo{$\Bigl|x^n\Bigr|$} % too small again (but bigger than \big) \foo{$\biggl|x^n\biggr|$} % too small again (but bigger than \big) \foo{$\Biggl|x^n\Biggr|$} % too small again (but bigger than \big) \foo{$\|x^n\|$} % expect two bars \foo{$\bigl\|x^n\bigr\|$} % expect two bars and bigger ones \stoptext %%% Stop example It gives the attached pdf file with latest minimals and mkiv.

See http://lua-users.org/lists/lua-l/2007-03/msg00564.html So I have changed the example to ------------------------------------------------------------- \starttext \startluacode math.randomseed(os.time()) _=math.random() \stopluacode Encode your Name and Surname as a \startluacode local a = {'null-terminated', 'dollar-terminated', 'Pascal'} context('%s string', a[math.random(1,3)]) \stopluacode \stoptext ------------------------------------------------------------- and this is working ok!

No indicators in registers when using french as main language
by Vianney le Clément 07 Apr '10

07 Apr '10

Hello, The subject says it all. \mainlanguage[fr] \starttext \index{Item}Item \placeindex \stoptext There is no indicator "i" in the index. It appears when you comment out the first line or change it to another language. Adding \setupregister[index][indicator=yes] does not help. Another, probably unrelated, problem is that \completeindex does not seem to do anything. Vianney

The code that follows seems to work but gives me a warning: pdfTeX warning: pdftex.exe (file ec-urw-courier.map): cannot open font map file The PDF lists 3 embedded fonts: LMRoman10-Regular, LMSans10-Regular & NimbusMonL-Regu.

I know this and I have triggerd this by hand. So there is a lot of time between. I have purged files between every run and I got the same result if I wait 1 second, 1 minute or 1 day. Wolfgang

Option /TwoPageRight for \setupinteractionscreen
by Markus Finke 07 Apr '10

07 Apr '10

http://www.ntg.nl/pipermail/ntg-context/2008/031094.html An old thread with the same question. I need this option for doublesided pages like e.g. books. It’s very helpful to scroll non-continuous doublepages for a quick overview whitout activate each time the accordant button in the PDF viewer. Is this option implemented yet? Best regards, Markus
