setupinteraction and macroexpansion
by Andreas Schneider 19 Jun '12

19 Jun '12

Hello, I'm a bit lost with macro expansion here. I try to use some macros to set the title (and subject) of the PDF document. The attached minimal example shows what I want to achieve. I tried def, edef, gdef, define, explicit expand, expandoneafter, etc. etc. without any success. Whatever I do, the title field in the PDF metadata always contains the raw "\date..." command instead of the formatted date. Any suggestions? -- Best Regards, Andreas

Hello, (my apologies if this message is duplicated - our mail server was out-of-order some time) how to call "\box0" and "\hbox to3cm{abc}" by Lua? ---- \startluacode context[[\box0]] % OK but a "nicer" way preferred, so keep on trying - context.box(0) % Error context.box{0} % Error context.box"0" % Error context.hbox({to = "cm"}, "abc") % Error \stopluacode ---- TIA.

Strange page breaks
by Andreas Schneider 19 Jun '12

19 Jun '12

Hello, the attached example causes very strange page breaks. 1. The subsubsubject is the last line on the first page. That doesn't look very nice. 2. The xtable is broken although the whole table fits on that page. Is there anything I (or you? :-)) can do about these two problems? #This is LuaTeX, Version beta-0.70.2-2012052100 (TeX Live 2012/W32TeX) #ConTeXt ver: 2012.05.24 19:36 MKIV fmt: 2012.6.18 int: english/english -- Best Regards, Andreas

horizontal spacing between only two rows
by Helmut Schwertner 18 Jun '12

18 Jun '12

Hello, in the following example it is possible to split a table vertical (between the first and the second column with (\startxcell[distance=5pt] test \stopxcell). \starttext \startxtable[option={stretch,width}] \startxrow \startxcell[distance=5pt] test \stopxcell \startxcelltest \stopxcell \startxcelltest \stopxcell \stopxrow \startxrow \startxcelltest \stopxcell \startxcelltest \stopxcell \startxcelltest \stopxcell \stopxrow \startxrow \startxcelltest \stopxcell \startxcelltest \stopxcell \startxcelltest \stopxcell \stopxrow \stopxtable \stoptext But how can I get horizontal spacing between "only" two rows, and not for the whole table? Thank you, Helmut -- ******************************************************** Helmut Schwertner 28201 Bremen eMail: helmut.schwertner(at)gmx.de

Refreshing (synchronizing) values between Lua variables and TeX registers
by Jaroslav Hajtmar 18 Jun '12

18 Jun '12

Hello ConTeXist and Lua experts Is there any way to refresh values between the values stored in Lua code and TeX registers? I need to evaluating the values of TeX registers (counters, dimensions, height of boxes, etc.) during the Lua cycle. I would like in the cycle read values from the TeX registers and write back there so that all values were always synchronized. Or I need advice on how to proceed. Most of my Lua code is in a separate file in Lua function. Is there a universal way to "jump out of cycle" to TeX synchronize all values between TeX registers and Lua values (even at the cost of slowing down) and then go back into the cycle and continue? I do not write cycles using the TeX macro language, but so far I'm failing in way around it. What I need to I knowing or What I need to learn? Thanx Jaroslav Hajtmar The minimal example shows (maybe) what I mean: \newcount\testcount \def\countrefresh{\directlua{tex.count.testcount = tex.count.testcount + 1}} \def\universalrefreshcommand{\directlua{-- ???}} \def\printdebuginfo{ \directlua{tex.sprint(': ',tex.count.testcount, " - ", "\\the\\testcount","\\par")} } \starttext Here values are not synchronized: \testcount=0 \startluacode local i=0 for i=1,5 do tex.sprint(i) tex.count.testcount = tex.count.testcount + 1 tex.sprint("\\printdebuginfo") end \stopluacode \blank[big] Here values of textcounter are synchronized: \testcount=0 \startluacode local i=0 for i=1,5 do tex.sprint(i) tex.sprint("\\countrefresh") tex.sprint("\\printdebuginfo") end \stopluacode \blank[big] Is there a universal way to "jump out of cycle" to TeX synchronize all values between TeX registers and Lua values (even at the cost of slowing down) and then go back into the cycle and continue? \testcount=0 \startluacode local i=0 for i=1,5 do tex.sprint(i) tex.count.testcount = tex.count.testcount + 1 tex.sprint("\\universalrefreshcommand") tex.sprint("\\printdebuginfo") end \stopluacode \blank[big] \stoptext

labeltext assignment
by Philipp Gesang 18 Jun '12

18 Jun '12

Hi all, there appears to be something special about how the key-value list works with \setuplabeltext: ······································································· \setuplabeltext [ foo=bar, %% <- comma not allowed here? % foo=bar %% <- works ] \starttext \labeltext{foo} \stoptext ······································································· Normally the trailing comma causes no trouble, but here it won’t even compile. Best regards Philipp

Deleting "-temp" files
by Aditya Mahajan 18 Jun '12

18 Jun '12

Hi, context --purgeall deletes all temporary files (i.e., files containing "-temp-"). In fact, I had requested this feature so that the filter module does not clutter the current directory with temporary files. However, there is a bug. ConTeXt deletes all files containg "-temp" (note the missing "-" at the end). So, $ touch A1-temperature.tex $ context --purgeall gives mtx-context | purged files: A1-temperature.tex AFAICS, mtx-context.lua is correct. It contains "-temp-" as expected. So, I don't know why files containing "-temp" are deleted. Aditya

by Jan Pohanka 17 Jun '12

Hello, I'd like to use C-Pretty-Printing module. As it is listed on http://modules.contextgarden.net I thought it should be installed by first-setup.sh --modules=all. Unfortunately this module is missing even all others are installed. best regards Jan -- Tato zpráva byla vytvořena převratnou poštovní aplikací Opery: http://www.opera.com/mail/
