Modules::documentation
Modules as name come from modules
switch in
texexec --pdf --modules module name
or
texmfstart texexec --pdf --modules module name
which is
a way to make pdf of documentation and code of module name .
- first, see Inside_ConTeXt in [1];
- also, see CONTEXT System Macros at [2]
- User:Luigi.scarso/modules.pdf for a comprensive set of pdf
-- Maybe you are searching for Modules, ie extensions to ConTeXt's core functions.--
Other stuffs
- AutoSize: see supp-fun.tex. Some stuff here: http://wiki.contextgarden.net/User:Luigi.scarso/autosize
- Two SRA3 papers labels here http://wiki.contextgarden.net/Image:SRA3.jpg
- I have download preprint of EUROTEX 2005 [3] It's very interesting.
- For EUROTEX 2006, see slides here:http://www.matexhu.org/eurotex2006/lectures/
- For EUROTEX 2007, see some slides here: http://www.logosrl.it/context/EuroTeX2007/
- Also very interesting are colors (here [4])
- Is Indesign CS2 better than ConTeXt ?

Luatex examples
Examples from Vyatcheslav Yatskovsky <yatskovsky@gmail.com>
- Say you needed to prepare about twenty test papers with 10 questions per a paper. Examples: "1. convert Dec 36 into Hex", "2. convert Bin 10010101 into Dec", etc. The wording of every question has not to be changed through papers, only numbers had.Instead of filling in numbers manually, you can wrote simple lua scripts to generate random numbers right inside the document:
% question involving random decimal number Convert \ctxlua{n=math.random(30,60) ; tex.print(n) ;}\low{10} into Bin. % question involving random binary number Convert \startluacode for c = 1, 16 do n = math.random(0,1) tex.sprint(n) end \stopluacode\low{2} into Hex.
- Perform logical AND, OR and XOR under the following pair of hexadecimal numbers:
\startluacode n = math.random(10,255) m = math.random(10,255) tex.print(string.format("%X, %X", n, m)) \stopluacode
- Encode your Name and Surname as a
\startluacode a = {'null-terminated', 'dollar-terminated', 'Pascal'} tex.print( string.format('%s string.', a[math.random(1,3)]) ); \stopluacode
Luatex hosts python
Following [5] I was able, in a linux box, to modify luatex-snapshot-20070820.tar.bz2 so that luatex --luaonly can host python. Of course \directlua0{....} also works.
