marginrule does not work properly in wiki
by Vyatcheslav Yatskovsky 11 Apr '10

11 Apr '10

Hello, The following example does not work properly in wiki (the rule is missed), while in mkIV it's OK. \starttext \startmarginrule The sound of a duck is a good demonstration of how different people listen to a sound. Everywhere in Europe the sound is equal. But in every country it is described differently: kwaak||kwaak (Netherlands), couin||couin (French), gick||gack (German), rap||rap (Danish) and mech||mech (Spanish). If you speak these words aloud you will notice that in spite of the consonants the sound is really very well described. And what about a cow, does it say boe, mboe or mmmmmm? \stopmarginrule \stoptext http://wiki.contextgarden.net/Reference/en/startmarginrule Regards, Vyatcheslav

Without \definerreference there is no difference form ordinary \item, but \definerreference gives an error. \setupinteraction [state=start] %\definerreference[content][] %gives error \starttext \startitemize \but [content] ... \stopitemize -- Best Regards, Vyatcheslav Yatskovsky

Why any substring is not find inside string?
by Jaroslav Hajtmar 11 Apr '10

11 Apr '10

Hello, Sorry for my beginners question. I am experimenting with CSV parsing and I have miscellaneous delimiters. Finding any delimiters is OK, but with any delimiters are problem - there are not to find inside string. Here is my minimal example: \starttext \startluacode text2split='"1";"GYZA";"382/2010";"482/2010";"402";"Májkova";"Barbora";"20.4.1995";"Zábřeh, Skalička 48";"789 53"' delim_from, delim_to = string.find(text2split, '";"') tex.sprint(tostring(delim_from),' - ', tostring(delim_to),'\\par') -- OK text2splitA='!1/;!GYZAs 482/2010/;!GYZA 382/2010/;!GYZA 482/2010/;!402/;!Májková/;!Barbora/;!ž/;!20.4.1995/;!Zábřeh/;!ČR/;!Mírov 69/;!Mírov/;!789 53/;!Májková/;!Michaela/;!Mírov 69/;!Mírov/;!789 53/;!/' delim_from, delim_to = string.find(text2splitA, '!;/') tex.sprint(tostring(delim_from),' - ', tostring(delim_to)) -- Not finding \stopluacode \stoptext Where is problem, where I making a mistake (I am beginning with Lua). Thanx Jaroslav Hajtmar

Thank you for answer, Wolfgang. > ConTeXt has no \but command although i think there was one in the past. I'm afraid you are wrong. See updated wiki page: http://wiki.contextgarden.net/Reference/en/but P.S. What about to wikify \show command itself? Or it is not ConTeXt command? Regards, Vyatcheslav

Hi Willi and all NTG members, I recently asked about if I can work off my annual NTG membership fee. Now I see great possibility for this. I can take an obligation to clean up *all* http://wiki.contextgarden.net/Category:Reference_Cleanup concerning http://archive.contextgarden.net/message/20100411.134521.3f2da72d.en.html -- Best Regards, Vyatcheslav Yatskovsky

> Help needed: texshow-web/command referenc Gladly started with this, but two questions arose: 1) What is "the standard"? What formatting errors too look for? Should they be evident or subtle? 2) Should the description be added before removing Reference_Cleanup? Foe example, \but wiki page looks meaningless without the descrption. http://wiki.contextgarden.net/Reference/en/but -- Best Regards, Vyatcheslav Yatskovsky

MetaPost in TABLEs ?
by Steffen Wolfrum 11 Apr '10

11 Apr '10

Hi all, In a book on construction engineering I found two kind of tables that presumably could be set very nicely in ConTeXt (see attachments). Set with MetaPost within natural tables? 1) Curly braces that span over cells: Their height should be depending to the cell's height (nr=2 oder nr=3). http://werksatz.com/attachments/braces.jpg 2) Arrows that are pointing from one cell to an other (middle or border of cell), http://werksatz.com/attachments/arrows.jpg To me this looks like standard purpose, that most like is already pre-defined somewhere in Metapost/MetaFun/ConTeXt (MkII please!) ... Is there any MetaPost guru out there that knows these cases? Thank you, Steffen
