Re: [NTG-context] Suggestion
Anyway, I highly respect the ConTeXt and LuaTeX's work. But if Taco and Hans can : - use a proper regexp library (like lrexlib?), not the silly lpeg PEG are not silly at all. PEG *include* regex, but not viceversa, and it seems to have the same power of CFG, so you can build a parser for pratically anything (and you can not do this with regex) . Perhaps the reverse sentence has more sense: drop the silly (?) regex, use the new peg. For what I know the reverse side of lpeg is that a file must be loaded in memory completly. - more powerful multi columns (maybe not through gird typesetting?) Maybe columnset can do more, or we need more examples from hans . - full support of xslt:) why not xquery too? Are mkiv supposed to be a full xml processor ? A bit of xslt can be done with lpeg (and not regex), but usually it's better to prepare a xml to typeset before processing with mkiv (use the right tool for the right task).

I read that OpenType fonts are actually Type 1 fonts embedded in an archive. So I used this 't1disasm' tool I found after wikipedia article on postscript fonts and used it to decode one of ConTeXt minimal distribution font file into a nice to read text file that looks like the transcript below, and it seems to be something I could easily understand if I find a reference. I would like to ask you if I'm in the proper direction. There are some issues I can't understand, like how can I make OpenType fonts out of Type 1 fonts when the later are supposed to only contain 256 characters (aren't they?). Or how to understand this text file format so I can write my own glyphs. Do you think I'm in the right direction. Do you think there's an easier or better way if I want to create fonts without using existing graphical tools? Without trying to answer your question ... Just a few references that I think you should read: 1.) If you want to understand the code that you have provided at the bottom of your document, start with http://www.math.ubc.ca/~cass/graphics/manual/ and http://www.adobe.com/devnet/postscript/pdfs/PLRM.pdf. Though it's by no means essential to understand. You can just as well use metapost as a programming language and that one could generate glyph shapes in PostScript for you. 2.) It makes sense to read the MetaFont Book to get some nice ideas, or at least browse through it. 3.) As Taco suggested, it's probably best to use fontforge, or maybe MetaType1 (if you can figure out how to use it). Once you create glyph shapes with some tool (that tool could be metapost if you really want to program glyphs), you can use another tool (like fontforge or some commercial program) to create a font out of the shapes. 4.)

Re: [NTG-context] Example of passing unexpanded text between \startfoo ... \stopfoo into Lua?
Hi Kevin,
A colleague and I are experimenting with strategies to implement a literate
programming module for ConTeXt, and we'd like to have something like
Im not exactly sure what you're trying to achieve, but perhaps you could do
this using a prettyprinter? A pretty printer gets passed each line in the
\startfoo \stopfoo block and can change the line in any way it wants
(including removing it). IIRC there is some minimal general preprocessing
done, something with whitespace I think.
\startcodeblock[language=c,file=foo.c, etc.][blockname]
// This is the main routine...
int main()
{
return 0;
}
\stopcodeblock
Perhaps you could say a bit about what the above should output?
