Installation: TeX-Live
by Jeffrey Drake 20 Mar '06

20 Mar '06

i resolved my problem before about accessing the wiki by making a copy of everything while at a friends house. So any information leading to a conclusion is at least a week old. I am on a linux install (SuSE 10.0) and the wiki indicates to install ConTeXt in the location '/usr/TeX/texmf'. Even before this step it says to setup the fonts for ConTeXt use: cd /usr/TeX/texmf/context/data sudo texfont type-tmf.dat --en=texnansi --fontroot=/usr/TeX/texmf --install --makepath But TeXLive 2005 (where I did install ConTeXt - but want to update it) that I am using does not have a 'texmf/context' directory. However, there is a 'texmf-dist/context' directory. I need some guidance to make sure this is the proper directory or not. The only other thing I note in the TeXLive docs: For texmf: This tree (texmf) is for the support files and documentation of the programs in TeX Live. It does not include the TeX formats and packages themselves. Another criteria: everything that can be classified automatically by Fabrice's tpm-factory goes in texmf-dist. If not, it goes in texmf. For texmf-dist: This tree (texmf-dist) is for the formats (plain, LaTeX, ConTeXt, and all the rest) and all the packages, together with their documentation and sources. Most everything used in day-to-day TeXing, except the binaries themselves. Another criteria: everything that can be classified automatically by Fabrice's tpm-factory goes in texmf-dist (or texmf-doc). If not, it goes in texmf. And yet another: texmf-dist should be distribution-independent, so that, in theory, it could be used by distributions other than TeX Live. So, no web2c/kpathsea-specific files. Thank you for all assistance, Jeffrey Drake

assembling typescript
by Karsten Heymann 20 Mar '06

20 Mar '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, after Patrick Gundlach convinced me at DANTE 2006 to switch the small scientific magazine project I'm currently working on for a client from LaTeX co ConTeXt, I'm now preparing a sample document for my client to convince him, and for that I need your help :) I've spent the last two weeks getting in touch wich context and I must say I'm really impressed, nice work! First challenge is that the document fonts are URW GaramondNo8 for the text and Bitstream Futura (really: Bitstream Geometric 211) for the headings. I managed quite easyly to install them with texfont and the instructions from the contextgarden wiki[1] and compile the sample document with either font family. But now I'm trying to (1) understand the typescript files and (2) build an own typescript putting those fonts together. This is what I have so far: \usetypescriptfile[type-ugm] \usetypescriptfile[type-bfu] \starttypescript [ifa][texnansi] \definetypeface [ifa] [rm] [serif] [garamond] [default] ~ [encoding=texnansi] \definetypeface [ifa] [ss] [sans] [futura] [default] ~ [encoding=texnansi] \definetypeface [ifa] [tt] [mono] [modern] [default] ~ [encoding=texnansi] \stoptypescript \usetypescript[ifa][texnansi] %\ifa \starttext \ss \input knuth \rm \input knuth \stoptext (type-ugm.tex and type-bfu.tex are attached). What happens is: When I compile the file a is it is set in computer modern. To enable my fonts I have to comment out \starttypescript, \stoptypescript and \usetypescript and enable \ifa. How do I activate my fonts via a typescript.

Multi-page tables
by Randall Skelton 20 Mar '06

20 Mar '06

Hi all, I'm having a bit of trouble getting multiple page tables to work when also using \placetable for captions. Essentially, I want: (1) Captions and the ability to reference with \in[]. (2) Alignment within a cell at a decimal point. (3) Span multiple pages with header/footer. I think I would prefer to use the standard 'TABLES' method but it looks like item 2 is only supported in natural tables? Below are two examples. I don't get page breaks in either case and the table runs off the bottom of pages 2 and 3. Thanks, Randall \definepapersize [width=8.5in, height=11in] \setupcaption[table] [location=top] \starttext \section{Testing} This is a silly table test. \placetable[page][tbl:sample] {Sample table

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.
