I am not very keen on maintaining my own version of ConTeXt so I would like to know if I can count on this feature being added. Thanks for your effort and kind regards, Christoph

total pages in external PDF
by Pablo Rodriguez 26 Feb '15

26 Feb '15

Dear list, I need to get the number of pages from an external PDF file that I also define with an \env. I think I could get something like this.: \def\Myfilename{\env{filename}} doc = epdf.open(arg[\MyFilename]) total_pages_ = doc:getNumPages() \def\Mypages{total_pages} But mixing both lua and ConTeXt commands the wrong way won’t work. Sorry, but this is all Greek to me. Although I see how it could be done, I cannot write the code for this. Which is the right way to get the code above working? Many thanks for your help, Pablo -- http://www.ousia.tk

CSV scanners built in ConTeXt - feature or bug?
by Jaroslav Hajtmar 26 Feb '15

26 Feb '15

Hi ConTeXist A few days ago Hans pointed me builtin CSV splitter. I tried to test it sure will come in handy for my needs. I found that if the CSV file contain a blank line, then it stops processing the file (see my minimal example). It is clear to me that the incorrectness of file format (eg. different number of columns in rows etc.) may cause interruption of processing, however, I want to ask whether there is an opportunity to process the CSV file with blank lines until the end of CSV file. I noticed that when I exporting data from Excel sometimes happens that in the export file will appear blank line. Is it interrupt processing a feature of a buildin splitter or is it a bug? Can it possibly somehow fix or add new functionality? Thanx Jaroslav Hajtmar Here is minimal example: \starttext \startluacode local mycsvsplitter = utilities.parsers.rfc4180splitter{ separator = ",", quote = '"', } local crap = io.loaddata("data.txt") -- with header variant local tablerows, columnname = mycsvsplitter(crap,true) inspect(tablerows) inspect(columnname) -- without header variant -- local tablerows = mycsvsplitter(crap) -- inspect(tablerows) for i=1,#tablerows do local l = tablerows[i] for j=1,#l do context(l[j]..", ") end context('\\crlf') end \stopluacode \stoptext % <-------------- here start data.txt file ----------------------> first,second,third,fourth 1,"2","3","4" "a","b","c","d" "foo","bar""baz","boogie","xyzzy" " "," "," "," " "And now","followed by","several","blank lines" "After several","empty rows","data continues","here" 11,"22","33","44" "aa","bb","cc","dd" % <-------------- and here stop data.txt file ---------------------->

textbackground
by Alan BRASLAU 26 Feb '15

26 Feb '15

Hello, For a multilingual document, alternating one language or another, not necessarily a bilingual, translated text, I thought about using textbackground to set-off paragraphs. This technique could also apply to a single language text having multiple levels of information, perhaps statements followed by discussion, etc. A problem appears with respect to footnotes that I do not know how to handle. If the backgrounded text goes across pages placing footnotes, then the footnote also gets the background. This is incorrect, perhaps a bug. Second problem, if a footnote of a backgrounded text gets placed on a following page, then it may not get a background. (It is not clear to me whether it would be correct for footnotes to get the background or not.) Of course, a solution to this secondary problem might be before={\startlocalfootnotes}, after={\placelocalfootnotes\stoplocalfootnotes}, although such a solution would postpone backgrounded footnotes to the end of the backgrounded text. Alan MWE: \definetextbackground [spanish] [location=paragraph, frame=off, before={\language[es]}, background=color, backgroundcolor=lightgray] \starttext \input darwin% \startfootnote \input dawkins \stopfootnote \input tufte \startspanish \input quevedo-es% \startfootnote \input cervantes-es \stopfootnote \stopspanish \input zapf \stoptext

Page numbering, new style and running heads.
by John Culleton 25 Feb '15

25 Feb '15

The new method of handling page numbering (roman and arabic) using e.g., \setupuserpagenumber[numberconversion=Romannumerals] \setcounter[userpage][5] works just fine if you remember one thing: in running heads the word "pagenumber" has to be replaced with "userpagenumber". But in the \chapter setup it is still "pagenumber" I spent the morning and a few extra minutes figuring those two things out. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html Updated PDF e-book: "Create Book Covers with Scribus 1.4.5" coming soon at http://www.booklocker.com/!

Problem with framed text.
by John Culleton 25 Feb '15

25 Feb '15

In several palces I want to set up framed text with a gray background and rounded corners. Here is my \setupframed description: \setupframed[ framecorner=round, frameradius=0.1, background=screen, backgroundscreen=0.70, backgroundcorner=round, backgroundradius=0.1, corner=round, radius=0.1 ] -------------------- And here is my first framed text: -------------------------- \startframedtext[middle] \centerline{A Vision Example} \QQ{[In the year 20xx], our company is internationally recognized as the premier supplier of [your food products]. We regularly exceed customer expectations by providing innovative and valuable [your food products] .} \stopframedtext ------------------------------------ The hangup seems to be the rounded corners. I am using texlive 2014. BTW the macro QQ is my shorthand for \quotation which is much to long IMO. But I am American and use double quotes a lot. \def\QQ#1{\quotation{#1}} That is not the problem. Everything works until I try to use rounded corners. The customer had them on the last edition of the book, probably done with MSWord (!) All answers appreciated. -- John Culleton Wexford Press

duplicate booklet arrangement
by Pablo Rodriguez 24 Feb '15

24 Feb '15

Hans, I need to generate a duplicate booklet from a PDF file. It would be like \setuparrange[2UP, singlesided]. But I need an extra imposition (this is what I have to do now), repeating the same booklet imposition one above each other. This would require a \setuppaper such as [A6][A4]. The first four pages would be: last|first last-1|first+1 last-2|first+2 last+3|first+3 last|first last-1|first+1 last-2|first+2 last+3|first+3 Just in case I haven’t explained myself, here you have a sample: https://archive.org/download/ensayo-escritura/ensayo-escritura.pdf. ConTeXt was used to typeset the book and arrange the booklet. But I needed to use another tool for the final imposition. I think it might be useful for other users also. Could this 2UPrepeated arrangement be included in ConTeXt? Many thanks for your help, Pablo -- http://www.ousia.tk

handling code in XML
by Pablo Rodriguez 24 Feb '15

24 Feb '15

Dear list, I have the following sample: \startbuffer[demo] <doc> <p><code><div>foo</div></code></p> <pre><code>for a > b & c</code></pre> </doc> \stopbuffer \starttext \startxmlsetups xml:initialize \xmlsetsetup{#1}{p|doc|code}{xml:*} \xmlsetsetup{#1}{pre/code}{xml:pre} \stopxmlsetups \xmlregistersetup{xml:initialize} \startxmlsetups xml:doc \xmlflush{#1} \stopxmlsetups \startxmlsetups xml:p \xmlflush{#1}\par \stopxmlsetups \startxmlsetups xml:code \begingroup\tt\xmlflush{#1}\endgroup\par \xmlinlineverbatim{#1} \stopxmlsetups \startxmlsetups xml:pre \xmlverbatim{#1} \stopxmlsetups \xmlprocessbuffer{main}{demo}{} \stoptext And I experience two issues: Is there a way to handle <code> (or <pre>) as verbatim, but translating the five entities that need to be escaped in XML? Which is the right way to link a <pre> or <code> to a type or typing command? Many thanks for your help, Pablo -- http://www.ousia.tk
