XML processing & columns & (almost) empty pages (?)

Hello, I'm processing a XML (.x18) with Ctx. At one place, I'm getting almost empty page (see pg. 6, "19 Svisle vedeni L56.2") - there is a subsection on the top of the page and a quite short two-column environment on the next page (why?); in preceding and following pages (which are principally the same) headings and column-environments are printed correctly each after another. I attached all files needed and I hope .x18 is minimized enough. (The original .x18 was several times bigger - I stripped unused data still to be able to reproduce the behavior.) How to avoid emptiness between the subsection and the following column environment on pg. 6? TIA. Best regards, Lukas -- Ing.

Re: [NTG-context] XML - accessing parental children attribute (was: some troubles)
by Procházka Lukáš Ing. - Pontex s. r. o. 18 Feb '15

Hello, a slightly modified example: ---- t.xml <a> <aa number="111">AA</aa> <ab number="222">AB</ab> </a> ---- and the Ctx source: ---- t.mkiv \startxmlsetups xml:T \xmlfunction{#1}{test} \xmlsetsetup{\xmldocument}{*}{+} % \xmlsetsetup{\xmldocument}{*}{-} % Empties output?! \xmlsetsetup{\xmldocument}{a/aa}{xml:*} \xmlsetsetup{\xmldocument}{a/ab}{xml:*} \stopxmlsetups \startluacode local aux = aux; if not aux then aux = {}; _G.aux = aux end xml.functions.aa = function(t) aux.num = t.at.number end \stopluacode \startxmlsetups xml:aa \xmlfunction{#1}{aa} \stopxmlsetups \startxmlsetups xml:ab \xmlfunction{#1}{ab} \ctxlua{context.section("New section " .. (aux.num or "??"))} \xmlflush{#1} \stopxmlsetups \xmlregistersetup{xml:T} \starttext Hello \xmlprocessfile{id}{t.xml}{} \stoptext ---- Two (remaining) questions: 1) Why the line "\xmlsetsetup{\xmldocument}{*}{-}" (try to uncomment!) causes the whole output is empty, even if I specify another operation for "a/ab" elements later? My intention is to have "{*}{-}" (don't flush anything by default), excluding elements specified later, e.g. "a/ab" (with another operation specified); how to achieve this? 2) How to get "aa.number" from within "ab" element? I believed "\xmlatt{#1/../aa}{number}" within "a/ab" will do that, but...? How to do that? I have a partial solution: when processing "a/aa", I save an attribute value to a Lua variable, which I use later; but this solution doesn't look very "clean" for me; I'd rather find a way to access parental (first) child attributes form within a node... Thank you in advance; I'm not very familiar with Ctx XML processing (so far)... Best regards, Lukas -- Ing.

\executesystemcommand dont work?
by Akira Kakuto 17 Feb '15

17 Feb '15

Dear Jaroslav, See your PATH carefully. For example I find a space between C:\1da\support\batch; and C:\Ruby\bin;C:\Windows\system32 i.e., C:\1da\support\batch; C:\Ruby\bin;C:\Windows\system32 There are many such spaces which should be removed. I think quotations such as "C:\Program Files (x86)\ghostgum\gsview" should be removed like C:\Program Files (x86)\ghostgum\gsview Best, Akira

setup different layouts in merged documents
by Pablo Rodriguez 17 Feb '15

17 Feb '15

Dear list, I have the following sample: \setuplayout[margin=20mm, width=fit, topspace=45mm, bottomspace=25mm,height=fit] \showframe \definelayout[first][margin=20mm, width=fit, topspace=110mm, bottomspace=20mm, height=fit] \usemodule[scancsv] \starttext \startbuffer[text-content] \definelayer[FirstLayer][state=start] \setlayer[FirstLayer]{First page} \definelayer[OtherLayer][state=continue] \setlayer[OtherLayer]{Other pages} \setupbackgrounds[page][background={FirstLayer,OtherLayer}] %~ \mbox{}\blank[75mm] \dorecurse{17}{\input zapf\par} \cA\hfill \cB \page \stopbuffer \opencsvfile{mail.csv} \doloop{\ifnotEOF\getbuffer[text-content]\nextrow\else\exitloop\fi} %OK \stoptext Contents of mail.csv: "ME";11/10/14 "You";05/02/14 "She";03/03/12 "It";03/03/14 t-scancsv.lua can be found at http://public.hajtmar.com/files/TeX/context/t-scancsv_ConTeXt_module/t-scan…. It is an awesome module for document merging. I’m having a problem that I don’t know how to solve. Each merged document has different layers for the first and other pages. But I don’t know how to set a different layout for the first page in each merged document. I have tried three options. 1. \definelayout[first] only works for the first page in document, not for each merged document. 2. \definelayout[even] and \definelayout[odd] work as long as each merged document contains less than three pages. Otherwise, it won’t work. 3. Adding an \mbox{}\blank[75mm] would do the job, but it’s a crappy way to work with ConTeXt (and it might lead to errors in the future). Is there a way to apply different layouts in the first and other pages in each merged document from the sample above? Many thanks for your help, Pablo -- http://www.ousia.tk

No escape to TeX for inline typing?
by Christoph Reller 17 Feb '15

Hi, How do I escape to TeX from inside an inline typing command? It works fine from a typing environment. MWE: \setuptyping[TEX][escape={[[,]]}] \definetype[typeTEX][option=TEX] \starttext \startTEX \I\can [[\em escape]] \stopTEX \typeTEX{\I\cannot [[\em escape]]} \stoptext Thank you for any feedback!

> No file latex.aux. > (./latex.aux) ) > No pages of output. OK, as I said previously, c:\windows\system32 does not exist in your PATH. In your command prompt echo "000" will work, but cmd /c echo "000" will not work. Please test in your command prompt set PATH=c:\windows\system32;%PATH% pdflatex --shell-escape latex It should work perfectly. After that, repair the PATH variable, by reading the manual of OS, if you don't understand. Thanks, Akira
