Different versions of Lua and error in the same versions of ConTeXt (Fedora vs Win7)
Hi ConTeXist... How can I find out what version of Lua uses ConTeXt TeXlive 2014 respectively what version of Lua uses Standalone ConTeXt? The point is that Pablo Rodriguez use Fedora 20, which comes with Lua-5.2.2. Pablo tested last version of my module ScanCSV and his current version of standalone ConTeXt gained mistake, while I compiled (with the same current version of Standalone under Win7) the same source code without error .... Error message from log file is: t-scancsv-2015-02-19.lua:81: assertion failed! stack traceback: [C]: in function 'assert' t-scancsv-2015-02-19.lua:81: in function 'ParseCSVLine' t-scancsv-2015-02-19.lua:123: in function 'parsecsvdata' t-scancsv-2015-02-19.lua:180: in function 'opencsvfile' [\directlua]:1: in main chunk Thanx Jaroslav Hajtmar

Hans, thanks for the reply. You write about the embedded CSV scanner. I was looking at contextgarden and on the Internet too, but I did not found any information about this. Can you, please, about built-in scanner CSV say more (link, minimal example etc.)? This thing interests me very much... Thanks Jaroslav Hajtmar Dne 22.2.2015 v 19:44 Hans Hagen napsal(a):

Hans, I don’t really need this at home, but I’m interested in this. I guess you mean m-database.mkiv. But I don’t have a clue on how to handle it. I mean, how to ignore the first line and how to make commands from the so-called cells (A2, B5...; to use them in document combination) reading an external file. Many thanks for your help, Pablo -- http://www.ousia.tk

Hans,

there are several variants, here is one: \starttext \startluacode local mycsvsplitter = utilities.parsers.rfc4180splitter() local crap = io.loaddata("c.txt") local list, names = mycsvsplitter(crap,true) inspect(list) inspect(names) local list, names = mycsvsplitter(crap) inspect(list) inspect(names) context.starttabulate { "|l|r|" } for i=1,#list do local l = list[i] context.NC() context(l[1]) context.NC() context(l[3]) context.NC() context.NR() end context.stoptabulate() \stopluacode \stoptext

in addition to the previous mail, t.txt is: first,second,third,fourth "1","2","3","4" "a","b","c","d" "foo","bar""baz","boogie","xyzzy" the code is in util-prs.lua (where all kind of parsing code lives) if you want to use that kind of code outside context you can do something like this: lua mtxlibs.lua --selfmerge foo.lua and then in your script load foo.lua this makes it possible to use the same set of helpers in context as well outside it (alternatively you can just use luatex as lua engine and mtxrun as script runner which is what we mostly do); this means that the context distribution provides all kind of means to set up workflows

Thanks for showing options in last mails. This is for me very interesting news, and certainly it will be very useful and inspirative for me. Jaroslav Hajtmar Dne 23.2.2015 v 9:49 Hans Hagen napsal(a):

Hi Hans. One more I ask You about this thing. When I have other separator - for example ";" then c.txt data file is: first,second,third,fourth "1";"2";"3";"4" "a";"b";"c";"d" "foo";"bar""baz";"boogie";"xyzzy" I was unable to figure out how to set the separator (and others default values too) so as to replace the default value in the library util-prs.lua Is there anything as utilities.parsers.rfc4180splitter.separator=";"??? This library is loaded automatically? Or as a module? Thanks Jaroslav Hajtmar Here is minimal example for Your correction: \starttext \startluacode local mycsvsplitter = utilities.parsers.rfc4180splitter() utilities.parsers.rfc4180splitter.separator=";" local crap = io.loaddata("c.txt") local list, names = mycsvsplitter(crap,true) inspect(list) inspect(names) local list, names = mycsvsplitter(crap) inspect(list) inspect(names) context.starttabulate { "|l|r|" } for i=1,#list do local l = list[i] context.NC() context(l[1]) context.NC() context(l[3]) context.NC() context.NR() end context.stoptabulate() \stopluacode \stoptext Dne 23.2.2015 v 9:49 Hans Hagen napsal(a):
