A strange request...
by Willi Egger 20 Feb '19

20 Feb '19

Hi all, I am siting with a project of making a “dwarsligger”, you know these books, printed on bible-thin-printing paper, which are about 12 x 8 cm. One opens them while holding them ‘landscape’ with the spine on the top… Now there is of course a little struggle with the page numbering. The reading page consists out of the even page together with the following uneven page. It is easy to print on the uneven page a page number, however this will result in uneven page numbers only throughout the book. My question is, whether there is an algorithm to print page numbers as follows: 1 2 3 4 5 6 7 8 9 (this is the ordinary numbering) 1 2 3 4 5 (this is the requested numbering) Does someone have an idea how to solve this? Any hints are most appreciated! Willi

Omitting part number in chapter numbers
by Simon Collier 20 Feb '19

20 Feb '19

Dear list. I would like to have a TOC that looks basically as follows when stripped down to the essentials: 1 Part1 1 Chapter1 2 Chapter2 2 Part2 3 Chapter3 I don't want the part number to be "part" of the chapter number (no 2.1, just 1, for example). This behaviour should apply both to the titles in the text and in the TOC.. With the code: \definestructureresetset[default][1,0,1][1] % reset part and section, but not chapter, from wiki \setuphead[sectionresetset=default] \setuphead[part] [placehead=yes, number=yes,] \setuplist [part] [number=yes,] \setuphead [chapter] [number=yes,] \setuplist [chapter] [number=yes,] \starttext \completecontent \startpart[title={Part1}] \startchapter[title={Chapter3}] \input knuth \stopchapter \startchapter[title={Chapter2}] \input tufte \stopchapter \stoppart \startpart[title={Part2}] \startchapter[title={Chapter3}] \input knuth \stopchapter \stoppart \stoptext I can make chapter numbers flow independently of parts, which is nice. But the numbering for chapters is like 1.1, 1.2, and 2.3, which is a good default, but not what I want. Is there any way to omit part number and get only the chapter number displayed? In wiki there is something that is almost suitable, namely setting: numbercommand={\determineheadnumber[chapter]\currentheadnumber\gobbleoneargument}] But this does not work for TOC, returning just zeros (and seems like also an extra zero is spilled on TOC, overall pretty hackish solution). When nothing seemed to work, I also tried to use an ugly macro that uses lua to format the argument #1 in the numbercommand nicely with the help of string functions, but it turned out the actual parameter #1 in numbercommand is something other than just a string with numbers and dots. If someone knows what it is, or how to find out, please point me to the right direction to better understand the system. Currently I'm unable to even print it to the terminal in order to see what actual characters are there, the following code outputting the length (seems to be 19 at least for me) works just fine as well as printing the string itself to the document. \startluacode userdata = userdata or { } function userdata.numberfun ( str ) context ( tostring(#str) ) end \stopluacode \def \mync #1 % { \ctxlua { userdata.numberfun ( [ == [ #1 ] == ] ) } } The idea seemed pretty standard and is used in many books, so maybe I've just completely missed the right way to approach this.

Mapping TABLE to xtable (module "ntb-to-xtb") doesn't recognize "c" option for columns
by Procházka Lukáš Ing. 20 Feb '19

20 Feb '19

Hello, it seems that xtable setup doesn't recognize the "c" option, which is recognized successfully by TABLE setup; tested on mapping provided by "ntb-to-xtb" module: ---- \usemodule[ntb-to-xtb] \restoreTABLEfromxtable \starttext \bTABLE \setupTABLE[c][1][width=1in] % Set 1st column width - OK with TABLE \bTR \bTD A \eTD \eTR \eTABLE \bgroup \mapTABLEtoxtable \bTABLE \setupTABLE[c][1][width=1in] % <- This line causes error - not recognized by xtable setup \bTR \bTD A \eTD \eTR \eTABLE \egroup \stoptext ---- Gives: " ... setup > error in line 1, namespace 'xtable', key 'c' setup > error in line 1, namespace 'xtable', key 'c' setup > error in line 1, namespace 'xtable', key 'c' ... " It might be useful to extend the module to understand "c" setup option as well. Best regards, Lukas -- Ing.

xtable and natural tables
by Damien Thiriet 19 Feb '19

19 Feb '19

Hi list, >From Hans xtable manual: As each cell is basically a \framed and as we need to do two passes over the table, this mechanism is not the fastest but it is some two times faster than the natural tables mechanism, and in most cases can be used instead. Manuals examples are of course short ones, but I understand this mechanism is faster even on tables that do not expand on more than one page. Does this mean, that extreme tables should now be considered as the recommended way to build tables? Are there simple cases, when natural tables should be obviously preferred? Thanks, Damien Thiriet

Weird TABLE split across pages
by Procházka Lukáš Ing. 19 Feb '19

19 Feb '19

Hello, a TABLE is split weirdly over two pages: - on the first page (here: page 8): the (repeated) header of the TABLE and the first body row followed by void space, - then (here: on the page 9) the remaining part of the TABLE; - see the sample attached. I'm not able to strip my real case more to make the example "more MINIMAL" - whatever next I delete, the problem disappears. Image of the bad break is attached; so are the source files. The resulting .pdf (~53 kB, bad TABLE break between page 8 and 9) is available here: http://leteckaposta.cz/330923784 Any idea what's going wrong? Best regards, Lukas -- Ing.

Macro for a header does not work as well

interactive tests with AcroJS
by Pablo Rodriguez 18 Feb '19

18 Feb '19

Dear list, is there any way that I can generate PDF document with ConTeXt containing a test with questions and multiple-choice answers and that the user can check the right and wrong answers (using AcroJS)? Sorry for the too general question, but I think it is clear enough. Many thanks for your help, Pablo -- http://www.ousia.tk
