pretty typesetting for matlab files
by Aditya Mahajan 17 Mar '06

17 Mar '06

Hi, I was trying to define a pretty printing environment for matlab files. The basic requirements that I have are % Numbers should be highlighted in a different color % Identify floating point numbers 1.1 and 1e-3. % Identify brackets % ()[]{} % Identify Punctuation % ,;<=> ... % Identify Operators % ^ + - / * .^ .* % Idenfity strings (enclosed in ' ' and " ") % Identify lines starting with % as comments. Show them % a different color. Identify %{ ... %} blocks as comments % identifiers function return case if else elseif do for while end % variables gt,lt,gt,lt,amp,abs,acos,acosh,acot,acoth,acsc,acsch, [snip].... a huge list The syntax is similar to both perl and MP. I had a look at the verb-*.tex files and tried to write verb-matlab. My attempt is attached. However, it does not work correctly. There are somethings that I could not figure out. 1. How to change the comment identifier. Matlab uses % as line comments and %{ .... %} as block comments. 2. For some reason Matlab variables are not recognized. 3. The punctuations are not identified. 4. '...' is not recognized as a string. The ' is output as a right quotation mark and not _neutral_ '. What would be a good way to include tex commands in the comments? Matlab recognizes %% as a special comment (begining of a cell). Is it possible to somehow translate %% into \MATLABcell, which is \bf by default but the behaviour can be changed if desired? See attachment verb-matlab.tex for my attempt and test.tex for an example. Thanks Aditya -- Aditya Mahajan, EECS Systems, University of Michigan http://www.eecs.umich.edu/~adityam || Ph: 7342624008

display math overcrowded with $$..$$
by Sanjoy Mahajan 17 Mar '06

17 Mar '06

The following file produces a overcrowded displayed formula (the integral sign almost touches the line of text below it): \starttext $$\ln(1+x)=\int_1^{1+x}{dt\over t}$$ is very useful. The logarithm is the area of regions A and B. \stoptext But if I use \startformula..\stopformula instead of $$..$$, then the spacing is fine. I make the pdf file with 'texexec --pdf try.tex' and see the problem on my laptop (Debian testing/unstable i386, teTeX 3.0-14 + cm-super font package): texexec : TeXExec 5.2.4 - ConTeXt / PRAGMA ADE 1997-2005 texutil : TeXUtil 9.0.0 - ConTeXt / PRAGMA ADE 1992-2004 tex : pdfeTeX, 3.141592-1.21a-2.2 (Web2C 7.5.4) context : ver: 2005.01.31 cont-en : ver: 2005.01.31 fmt: 2006.2.18 mes: english I thought a conTeXt upgrade might fix it, but I haven't (yet!) won the battle with teTeX and map and encoding files. However, the live ConTeXt (2006.02.15) on the Wiki displays, no pun intended, the same spacing problem. Should I not use $$..$$ for display math? I'm learning context as I convert my plain tex + eplain files. The Wiki page on Math <http://wiki.contextgarden.net/Math> says that context inherits its math from plain TeX, which implies that $$ should work. However, no examples on the page use $$, so maybe I shouldn't be so presumptuous. Although I'd like $$..$$ and \startformula..\stopformula to be equivalent, I can write a script to convert plain TeX $$..$$ constructions to \{start,stop}formula -Sanjoy `Never underestimate the evil of which men of power are capable.' --Bertrand Russell, _War Crimes in Vietnam_, chapter 1.

typing and linenumbering
by nico 16 Mar '06

16 Mar '06

Hello, I would like to print some listings, with their line numbers. To achieve this I use the following combination on framedtext, typing and linenumbering stuff. The output is pretty as I wish, but unfortunately the line numbers are *not* the numbers of the listing lines, but the numbers of the lines once wrapped in the frame. In the example below the first line is very long (the "blah blah" line), but in the output it is shown as 4 lines (with 4 line numbers). Is there a way to achieve this in a more integrated way with the typing environment? The other side effect of the method used is that it changes the linenumbering behaviour outside the typing environment. I tried the "reset" option, but it doesn't change the intext location. Is there a possibility to come back to default settings? Last but not least, is it possible to customize the wrapping behaviour so that an arbitrary command can be called before the cut, and another command after the cut? What I would like to have is {\space\wrapsign} before the cut and an indentation after the cut to show that the line is wrapped. Thanks for any hints. % listing frame \defineframedtext [framelisting] [background=screen, frame=off, strut=yes, offset=2mm, width=broad, framecolor=black, align=right] \definetyping[prog] \setuptyping[prog] [bodyfont=small, before={\setuplinenumbering[style=small,step=2,start=3,location=intext] \startframelisting\startlinenumbering}, after={\stoplinenumbering\stopframelisting}] % after={\stoplinenumbering\setuplinenumbering[reset]}] \startprog first line: blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah blah second line third line last line \stopprog Regards, BG

Problem with typescripts - oldstyle numbers
by Thomas A. Schmitz 16 Mar '06

16 Mar '06

I just realized the pattern in a somewhat unexpected behavior in a typescript. It defines several instances of Adobe Caslon (with or without certain ligatures, oldstyle, proportional numbers etc.). I want typewriter and math from Latin Modern. In the end, the typefaces are defined: \starttypescript [Caslonpnum] \definetypeface [MyCaslonpnum] [rm] [serif] [caslonpnum] [default] [encoding=\typescripttwo] \definetypeface [MyCaslonpnum] [tt] [mono] [modern] [default] [encoding=\typescripttwo] \stoptypescript Here's the catch: as soon as I add a definition for a math font: \definetypeface [MyCaslonpnum] [mm] [math] [modern] [default] [encoding=\typescripttwo] oldstyle figures will always be taken from the math font. If I delete this line from the typescript, I get the oldstyle figures from the font defined as [OldStyle]. Looks like a bug to me. Or am I misunderstanding something? Thomas

how to produce text with facing translation?
by Thomas A. Schmitz 16 Mar '06

16 Mar '06

Hi all, I think I remember some of you already had experience with this, and I'd be grateful for a few hints that can get me started: as a textbook for a class I'm teaching, I want a booklet that will have Greek text with facing German or English translation. For the setup, I was thinking of \setuppapersize[A5][A4] \setuparranging[2*2] What would be the best way to achieve this? A few requirements: 1. The left-hand pages will have the Greek text, the right-hand pages the German translation. 2. In general, the German translation will be somehwat longer than the original, so I need to be able to insert manual breakpoints, but I want these breakpoints to occur in midparagraph so the last line of the page isn't truncated. 3. Would it be possible to have two sets of footnotes, one for the text, one for the translation? 4. I guess that I'll need to use a grid to make ligns align, right? Any help, as always, will be appreciated. Best Thomas

Colors and images Context
by luigi scarso 16 Mar '06

16 Mar '06

2 questions for colors 1) Does ConTeXt offer complete color gestion as pdf spec 1.6 or there are some features not implemented ? 2) Preparing a pdf with bitmap colored images for offset press (ie covers for manuals): are png or jpeg an optimal solution or tiff is better ? RGB or CMYK ? Thanks in advance luigi

question about figures and labels
by WN 16 Mar '06

16 Mar '06

Hi, I am trying to reference the 2 subfigures in my text , something like Some text .... \placefigure[][figuur7]{Centrifugale kracht $\vec{F}_{F}$ en centripetale kracht $\vec{F}_{c}$} { \startcombination[2*1] {\externalfigure[Drawings/figuur7a]} {} {\externalfigure[Drawings/figuur7b]} {} \stopcombination } In \in{figure}[figuur7a] and \in{figure}[figuur7b] one can see ......... ...... But I don't know how to setup the labels figuur7a, figuur7b ? I cannot find anything related on Wiki or in this newsgroup, I think it should be possible with Context ? Kind regards Wim Neimeijer

Fonts: Margin kerning: quotes not hanging?
by David Wooten 15 Mar '06

15 Mar '06

Greetings ConTeXters, I've noticed recently that quotation marks (single + double), as well as parens, and perhaps others are not undergoing the expected margin kerning adjustments. Expected being those that are assigned to them in hand-def.tex. Punctuation like . , ; - -- --- all kern as expected. Is hand-def.tex just an example file? While I expect I'll have to make fine tuning adjustments in my font's own typescript file, where should I make overall adjustments? (e.g. I pretty much always want quotes to hang.) I'm using Adobe Minion Pro in this case, if this makes a difference. Thanks very much, David
