Hi, How do you access the first paragraph of each chapter ? I guess with... \setuphead[chapter][after=\PlayWithFirstParagraph] \def\PlayWithFirstParagraph... How to fill in the dots ? Alan

overprint and \currentcolorname in mkiv
by Peter Rolf 06 Mar '09

06 Mar '09

Hi Hans, the subject is re-used from an older mail http://archive.contextgarden.net/message/20080912.160921.cb5bba9d.en.html >> Currently I try to adapt some mkii code to mkiv. Overprinting should >> only be enabled if >> - a given maximum font size is not exceeded and >> - the current text color is black. >> >> So I also need \currentcolorname (or something similar) for that test. >> >> [colo-new.mkiv:] >> \def\currentcolorname{\s!black} % todo You were so kind to add \doifblackelse in mkiv, but without a working \currentcolorname it is pretty useless at the moment. I want to closure the (inconvenient) prepress topic and overprinting is the last unsolved problem. Any chance that this will be implemented in the near future?

boldstyle for numbers in defineenumeration
by Xan 06 Mar '09

06 Mar '09

Hi, Is it possible to put "numerstyle=boldstyle" in this enumeration?: \defineenumeration [exercici] [text={\startcolor[middlecyan]Exercici\stopcolor},headstyle=bold,between=\blank,titledistance=0em,textdistance=1em, stopper={.\space},location=serried,titleleft=(,titleright=),width=fit,headstyle=\ss] For the other hand, is it possible to make it's a framed? Thanks a lot, Xan.

the other blog (chemical stuff)
by Hans Hagen 06 Mar '09

Hi aditya, some comments on the other bog item ... (others may wikify it) you can do a quick and dirty solution as well (tested in mkiv): \def\MoleculeC#1{$\enablesupersub\tf#1$} now, concerning the lua solution, it looks pretty clean and ok, but there is some room for improvement ... the following version supports nested braces and numbers (we can let this evolve in a proper chemical subsystem if needed since eventually i will replace ppchtex anyway) \startluacode local molecule = { } local format, sprint = string.format, tex.sprint function commands.justtext(one) sprint(tex.ctxcatcodes,one) end function commands.low(str) sprint(tex.ctxcatcodes,format("\\low{%s}",str)) end function commands.high(str) sprint(tex.ctxcatcodes,format("\\high{%s}",str)) end function commands.lowhigh(one,two) sprint(tex.ctxcatcodes,format("\\lohi{%s}{%s}",one,two)) end function commands.highlow(one,two) sprint(tex.ctxcatcodes,format("\\hilo{%s}{%s}",one,two)) end local lowercase = lpeg.R("az") local uppercase = lpeg.R("AZ") local plus = lpeg.P("+") local minus = lpeg.P("-") local digit = lpeg.R("09") local sign = plus + minus local cardinal = digit^1 local integer = sign^0 * cardinal local leftbrace = lpeg.P("{") local rightbrace = lpeg.P("}") local nobrace = 1 - (leftbrace + rightbrace) local nested = lpeg.P { leftbrace * (nobrace + lpeg.V(1))^0 * rightbrace } local any = lpeg.P(1) local subscript = lpeg.P("_") local superscript = lpeg.P("^") local content = lpeg.C(nested + integer + any) -- could be made more efficient local lowhigh = subscript * content * superscript * content / commands.lowhigh local highlow = superscript * content * subscript * content / commands.highlow local low = subscript * content / commands.low local high = superscript * content / commands.high local justtext = lpeg.C((1 - somescript)^1) / commands.justtext local parser = (sometext + lowhigh + highlow + low + high)^0 function commands.molecule(string) parser:match(string) end \stopluacode \def\molecule#1{\ctxlua{commands.molecule("#1")}} \molecule{H_2SO_4^-2} \molecule{H_2SO_4^{-2}} \molecule{H_2SO_4^{-2{x}}} Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Eliminate space between float and caption
by Michael Bynum 05 Mar '09

05 Mar '09

I am trying to find a way to reduce/eliminate the space between a figure and a caption. The default amount looks rather large to me: larger than the spacing between the caption and the body text. I tried to use the inbetween option in \setupcation, but I can only seem to increase the space between the figure and caption and not reduce it. I saw a reference to details.pdf in the mailing list about more advanced examples of captions, but when I went to www.pragma-ade.com/temp the page no longer exists and I couldn't find details.pdf. Thanks, Mike

Re: [NTG-context] Up the contents of table

Sorry but with your question only there is no way to understand what you mean, I texed now your example (please add next time \starttext ... \stoptext and load all required packages) and saw what you mean. The two pictures and the text in the middle column should align at the top of the table. Natural tables are better suited for this kind of table because you can use the 'align' key. \bTABLE [frame =off,align=middle,width=4.5cm,background=color,backgroundcolor=gray] \bTR \bTD[nx=3,foregroundstyle=\ssbf] Com s'identifica una funció mitjançant la seva representació gràfica? \eTD \eTR \bTR[topframe=on,bottomframe=on] \bTD <graph 1> \eTD \bTD <text> \eTD \bTD <graph 2> \eTD \eTR \eTABLE Wolfgang
