why nil argument
by Hans van der Meer 14 Nov '10

In transforming dates through a Lua-call I get a nil error I do not understand. The luatex code = \startluacode hvdm = hvdm or {} require "lpeg" -- Transform date in Lua from yyyymmdd to dd-mm-yyyy with checks hvdm.day = lpeg.R("02") * lpeg.R("09") + lpeg.P("30") + lpeg.P("31") - lpeg.P("00") hvdm.month = lpeg.P("0") * lpeg.R("19") + lpeg.P("10") + lpeg.P("11") + lpeg.P("12") hvdm.year = lpeg.R("12") * lpeg.R("09") * lpeg.R("09") * lpeg.R("09") hvdm.date = lpeg.C(hvdm.year) * lpeg.C(hvdm.month) * lpeg.C(hvdm.day) * -1 / "%3-%2-%1" \stopluacode \def\FormatDate#1{\ctxlua{tex.print(tostring(hvdm.date:match(#1)))}} Calling \FormatDate(1) is OK although it returns "nil" (correct would be #1 = 20101114 Calling \FormatDate(A) is not OK with the error: ! LuaTeX error <main ctx instance>:1: bad argument #1 to 'match' (string expected, got nil) stack traceback: [C]: in function 'match' <main ctx instance>:1: in main chunk. It is no problem if the function returns the string "nil" from tostring() but an error like this I would like to avoid. Hans van der Meer

Animations (again, but different)
by Erik Margraf 14 Nov '10

14 Nov '10

Dear Contexters! In the last few days I could read a few posts about "animations" in a resulting PDF document. Some statements mentioned java script as possible means to create an animation. Is it possible to do the following (which is rather simple using html and javascript)? -- Have a bunch of thumbnail pictures -- When you click on a thumbnail you see a larger version of the same picture -- With the next mouseclick the picture vanishes (you see the gallery of thumbnails again) if yes, how? Any hints are welcome. kind regards Erik

Croatian translation of core-mis.mki[iv] and m-units.tex
by Vedran Miletić 14 Nov '10

14 Nov '10

Hi, I translated the strings in core-mis.mki[iv] and m-units.tex to Croatian. Updated files are here: http://www.inf.uniri.hr/~vmiletic/context/core-mis.mkii http://www.inf.uniri.hr/~vmiletic/context/core-mis.mkiv http://www.inf.uniri.hr/~vmiletic/context/m-units.tex There are many more strings in m-units.tex that could (and probably should) be translated, if this code will remain in use (since Hans and Wolfgang talked about new module for units). Regards, -- Vedran Miletić

Dummy buff-ver.mkiv question
by Renaud AUBIN 13 Nov '10

13 Nov '10

Hi folks, From http://wiki.contextgarden.net/Verbatim_text#Defining_your_own_set_of_colors and considering the following code snippet from buff-ver.mkiv \definepalet [colorpretty] [ prettyone=colorprettyone, prettytwo=colorprettytwo, prettythree=colorprettythree, prettyfour=colorprettyfour] I conclude that we are limited to a four colors palet for our custom pretty printer… Right or wrong? Ok, from that basis, one solution could be to directly define custom colors within pret-xxx.lua… but how? Any ideas? Renaud

Footnote links in the body?
by Marco Pessotto 13 Nov '10

13 Nov '10

Hello there. I notice a strange behaviour with the footnote linking. Let's use the following minimal example: \setupinteraction[state=start] \starttext test\footnote{test} \stoptext Compiled with mkiv, the latest beta (ConTeXt ver: 2010.11.12 18:22 MKIV fmt: 2010.11.13), luatex, version beta-0.64.0-2010111215 (Gnu/Linux intel 32bit) The ¹ in the body is green, but it's not clickable, while the backlink is red, is clickable but it reset the zoom at "fit page", which is kind of annoying when reading (if you have to jump between the footnotes and the body). This happens with evince and acroreader. Using mkii the link in the body is green, but doesn't react on click. Am I missing something? Probably it's a known issue, but I couldn't find any post or wiki article (I'll write it if I can understand what's going on). I also find this in the logs: systems : begin file fn.tex at line 3 references : invalid page reference: 0 (which I suppose is the footnote link). Last question en passant: is this list the right place to post bug reports? -- Marco
