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

Help needed: texshow-web/command reference
by Patrick Gundlach 11 Apr '10

11 Apr '10

Hi all, the garden maintainers have moved the command reference from texshow-web (http://texshow.contextgarde.net) to the wiki, below the page http://wiki.contextgarden.net/Category:Reference/en This means, everybody can update the command reference now! Hooray! The contents has been transferred automatically, but this process can lead to some unwanted formatting errors. To find these errors, we need your help: Everybody: please pick one random command from http://wiki.contextgarden.net/Category:Reference_Cleanup and make if this looks ok. If you are finished, please remove the first two lines from that page and save it. If everybody from this list helps with _one_ command, we are quickly done with checking the new reference! Thanks for your help! Patrick (for the garden maintainers)
