Modules::documentation
Modules as name come from modules
switch in
texexec --pdf --modules module name
or
texmfstart texexec --pdf --modules module name
or
texmfstart texexec --luatex --modules module name
which is a way to make pdf of documentation and code of module name .
For lua code, I've found convenient
mtxrun --internal x-ldx module.lua
texmfstart texexec --use=x-ldx --forcexml module.ldx
- 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/
- Also very interesting are colors (here [4])
- Is Indesign CS2 better than ConTeXt ?

Luatex examples
Examples from Vyatcheslav Yatskovsky <yatskovsky at gmail.com>
- Say you needed to prepare about twenty test papers with 10 questions per a paper, that is, 200 questions. Examples: "1. convert Dec 36 into Hex", "2. convert Bin 10010101 into Dec", etc. The wording of every question should remain the same, only figures have to be changed through papers. Instead of inventing 200 numbers, you can write simple Lua scripts that generate random values and put them inside your question text:
% random decimal number Convert \ctxlua{n=math.random(30,60); tex.print(n);}\low{10} into Bin. % random binary number Convert \startluacode for c = 1, 16 do n = math.random(0,1) tex.sprint(n) end \stopluacode\low{2} into Hex. % a pair of random hexadecimals 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 % random word Encode your full name as \startluacode a = {'null-terminated', 'dollar-terminated', 'Pascal shortstring'} 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.
