Hi Everybody, First off, my actual interest is in Lua(La)Tex. It seems that several key features of OpenType are not yet supported by otfload. My direct interest would be GDEF and GPOS. From my understanding of things is that such things are first developed on the Context side the pulled in by LuaTeX. I will be setting up a drive with a Mac OS, and the Context source distro, just to kept things safe. I already have the LuaTeX source distro. I have started into OT-Specifican 1.6. I have started going top down into the lua source in the normal MacTeX 2012 distro. Just to learn how things are getting done. So here are my Questions 1) Is GDEF still not supported in font.loader 2) Is GPOS still not supported in font.loader 3) Are there any Program Specifictions anywhere to be had and where 4) Any Class diagrams, flow charts, UML or similar documentation and where for font manager and even Context or LuaTeX 5) Any of 3 and 4 in the source distribution? 6) Is the font.loader mainly in Lua or C? (I have not gotten that far yet?) (only a couple hours of work done) 7) Can I safely assume that at that there enough modularization in the code sothat I can work bottom up? That is add thing needed to the font.loader{} and font{} 8) Is there any special natural language convention when discussing Context inorder to differentiate between OT-Font-Table and Lua-Tables and data structures? I have self-taught myself LUA form the online reference(far from proficient though, but the lua sources for Context and LuaTeX will get me there fast or i will just fake it. Been around programming since mid-eighties, Have learned some 20-30 programming languages( Pascal, Modula2, Cobol, PM-L, Prolog, LISP, Perl, C, C++, Objective-C) just to mention a few. I think this is enough for now. Thanx in advance for any help and pointers. regards Keith.

linenotes: possible bug and feature request
by Pablo Rodríguez 02 Aug '12

02 Aug '12

Hi there, I have the following code: \mainlanguage[la] \definelinenote[linenote] \setuplinenote[linenote][rule=off,paragraph=yes,numbercommand=,inbetween=\qquad] \setupdescriptions[linenote][display=yes,location=serried,distance=1em]\starttext \startlinenumbering Sed \startlinenote[one]{entia: entitates W} entia \stoplinenote[one] non sunt multiplicanda \startlinenote[two]{praeter necessitatem: sine necessitate H} praeter necessitatem \stoplinenote[two]. \stoplinenumbering \stoptext And with latest beta I get an error, since blank spaces before \startlinenote...\stoplinenote are removed. So, the body contains “Sedentia” when it should read “Sed entia” (the same happens with praeter neccesitatem). I'm afraid this is a bug. The feature request is an option in linenotes that only number in the first linenote comming from the same line. You have this practice at line 7 from http://context.aanhet.net/epen2007/share/idris/cr-apparatus.pdf#page=46 and line 81 from http://context.aanhet.net/epen2007/share/idris/cr-apparatus.pdf#page=49. Could this feature be considered for future implementation? Many thanks for your help, Pablo -- http://www.ousia.tk

Left margin of vim module output
by Marco Patzer 01 Aug '12

01 Aug '12

Hi, how can I adjust the left margin of the output of the vim module? The core typing mechanism implements a “margin” key for this. The vim output also does not react to the “leftoffset” setting of the background mechanism. \usemodule [vim] \definetextbackground [code] [location=paragraph, %leftoffset=1cm, topoffset=5mm] \definevimtyping [C] [syntax=c, before={\starttextbackground[code]}, after=\stoptextbackground] \setuptyping [typing] [margin=1cm, before={\starttextbackground[code]}, after=\stoptextbackground] \starttext \startC /* This MEMB() definition defines a memory pool from * which we allocate neighbour entries. */ MEMB(neighbours_memb, struct neighbour, MAX_NEIGHBOURS); \stopC \blank \starttyping /* This MEMB() definition defines a memory pool from * which we allocate neighbour entries. */ MEMB(neighbours_memb, struct neighbour, MAX_NEIGHBOURS); \stoptyping \stoptext Marco

t-degrade.tex
by Peter Münster 01 Aug '12

01 Aug '12

Hi, Does it make sense, to port http://modules.contextgarden.net/t-degrade to mkiv, or is there already an existing solution in ConTeXt to downsample jpeg-images on the fly? TIA for any hints, -- Peter
