Syntax highlighting for C-code
by Richard Weickelt 15 Jan '12

15 Jan '12

Hi, I've tried to include some C-code into my document, but failed to enable syntax highlighting. Tested on: linux-64, context-2011.05.18 (same with the beta) stand-alone mkIV 1) \starttyping[option=C] just prints verbatim text. There seems to be no formatter for C out of the box. 2) t-vim did not work. It failed somewhere (unknown command sequence \installspacehandler) on loading (\usemodule[vim]) 3) http://wiki.contextgarden.net/Verbatim_text I tried to download pret-c and put it into the modules folder, but writing \installprettytype[C][C] failed, because it's not known (in mkIV). 4) mkII does not complain to exec \installprettytype[C][C], but this does not change anything either. \starttyping[option=C] seems to call a (maybe builtin?) formatter, but I could not get colors to work. I'm also lost in the documentation, because there are many places talking about syntax-highlighting. Does this thing work for anybody or is ist just my installation? Thanks Richard

footnote mechanism broken (3)

This one is even more disturbing: Just by setting the note's color to green, each footnote is set on a single page!!! \setupnote[footnote][textcolor=green]% <- without this line the notes are set right \starttext \dorecurse{10}{\input ward\footnote{just one line. a test footnote. just one line. a test footnote.}} \stoptext Steffen

t-vim module problems
by Wagner Macedo 14 Jan '12

14 Jan '12

Taking the message about "Syntax highlighting for C-code", I tried to use t-vim module. In that message: Richard Weickelt wrote: > 2) t-vim did not work. It failed somewhere (unknown command sequence > \installspacehandler) on loading (\usemodule[vim]) I can confirm this on latest Beta, downloaded today, ver: 2012.01.12 11:03 MKIV fmt: 2012.1.14 int: english/english. I attached the log file. On my current version (2011.05.18 18:04), I can compile the file, but the code cannot be viewed on generated PDF. The content of file I'm trying to compile is below. % teste.tex \usemodule[vim] \definevimtyping[C][syntax=C] \definevimtyping[ruby][syntax=ruby] \starttext \startitemize \item A hello world example in C \startC #include<stdio.h> int main() { printf("Hello World") } \stopC \item A hello world example in ruby \startruby puts "Hello World" \stopruby \stopitemize \stoptext -- Wagner Macedo

Lucida lVert rVert - no glyph printed
by Daniel Edwards 14 Jan '12

14 Jan '12

Hello everybody, Problem 1: I just notices that (at least for me) the $\lVert$ / $\rVert$ commands print no glyph with Lucida New Math. I search in the source files a bit, and found that in char-def.lua the lVert character is defined as U+02016 but in lucida-math.lfg it is mapped as U+02225. I was only able to reproduce this with context-current because with the beta I got some font-related internal errors when including lucida - but I guess this is another story :) but the two files are identical in those points in current and beta. According to gucharmap U+02225 is the "parallel"-symbol used to denote that eg. two lines are parallel and the U+02016 is the character usually used to denote the norm of a matrix/vector. Solution 1: I changed the entry in lucida-math.lfg from U+02225 to U +02016 and the lVert command produces the right glyph (any glyph at all :). As far as I can say, the spacing is a bit bigger than that of the absolute value $\lvert$ and $\rvert$, but that may be intentional. Just wanted to post this, if anyone has that problem too :) Problem 2: TikZ is not working in context-beta right now. a) When simply doing \usemodule[tikz] you get many errors "Undefined control sequence" for the \active command. I think this happens due some changes in the catc-ini module. I simply redefined \active with the \activecatcode macro and it compiles. b) But even then, parts of the diagram are shifted (see the examples below). I have prepared some minimal examples here: http://www.stud.mathematik.uni-stuttgart.de/~edwarddl/ I use TikZ mainly for drawing such diagramms, as it it relatively easy to use, but I use the current version for that and I simply testes the beta and it seemed not to work. Sincerely, Daniel

\setuppapersize & \externalfigure
by Gerben Wierda 14 Jan '12

14 Jan '12

\externalfigure[foo.pdf][factor=fit] nicely fits the mage on the page. The following snippet: \page\setuppapersize[A4,portrait][A4,portrait] \externalfigure[foo.pdf][factor=fit,orientation=90] behaves like this: the size is set to what fits *before* rotation. The order of orientation and factor does not matter. Is there anything I can do about that? Thanks, G

Error Line Number

Hey folks, I get the following error message when attempting to compile my book, but it doesn't appear to say what file / line number is responsible.

Page with minimum margins, maximum text width/textheight
by Gerben Wierda 14 Jan '12

14 Jan '12

How do I create a page with maximum text width, text height? I tried using \setuplayout with stuff like [textwidth=\pagewidth-1cm], but nothing happens. I need empty pages with minimum margins, just to be able to put other PDF's in that space. G

Merging PDF document of various page sizes. Can ConTeXt help?
by Gerben Wierda 14 Jan '12

14 Jan '12

Hello community, I have the following problem. I need to create a single PDF file where each page may have a different size and orientation. Say the first page is A4 portrait, the second is A3 landscape and so on. Can ConTeXr help? Each page contains a PDF image of some random size that is inserted. I have been looking around for a solution but haven't found one. I also tried Create.app, the drawing program. And I tried a program call PDF Merge and some others. Neither of these work, and most of the merge programs out there maybe merged, but changed the nice vector images into pixel images, completely destroying print quality. So, I am back where I started. Is there some fancy ConTeXt trickery I could use to do this? Summary: - One PDF as result - Each page has a different size and orientation - Each page contains a PDF vector image that is not to be converted to pixels Yours, G

Hi, an other strange thing related to footnotes can be seen here: \def\MyNote#1{\switchtobodyfont[12pt]\high{#1}} % <- gives small number %\def\MyNote#1{\switchtobodyfont[13pt]\high{#1}} % <- gives big number \setupnote [footnote] [textcommand=\MyNote] \starttext Hi there!\footnote{I’m a footnote.} \stoptext Please run it with 12pt and also with 13pt: The difference in the number's size is huge, not only 1pt!!
