(You can take a look at char-def.lua, math-vfu.lua > and some other files. It all needs to be improved and fixed.) Yes, the math in experimental is not working. see the attachment. However, I have a document which uses - Myriad Pro - a lot of math but I can use neither beta (failed to parse Myriad Pro) nor experimental (cannot typeset math) I use the nightly build version of LuaTeX provided by w32tex.

Hi, Myriad Pro is not working in recent version of ConTeXt (the same source works well in last release).

BibTeX again: citing without parenthesis
by J.A.J. Pater 29 Jan '09

29 Jan '09

The wiki suggests to make a macro: \def\onlinecite#1{\cite[left=,right=][#1]} for inline citations. However it says you can use this macro with: \onlinecite[myRef] It works for me with: \onlinecite{myRef} But not with \onlinecite[myRef] for in that case it produces: "Xxxxxxxxxx, 0000myRef]" Is the wiki wrong? Or is something else wrong? Thanks in advance, Adriaan.

lua questions
by Thomas A. Schmitz 29 Jan '09

29 Jan '09

Hi all, this is a bit OT and should probably go to a lua list, but since some people here are very proficient in lua and I feel less embarrassed about noob questions here... I have a half-functioning python script to convert entries from a classics database into the bibtex format. I want to rewrite it in lua and make it more functional. Three little problems/questions: 1. I found a script to convert Roman numerals via lpeg here: http://lua-users.org/wiki/LpegRecipes but it uses the syntax lpeg.Ca which my lpeg doesn't recognize and which I can't find in the lpeg manual. According to a talk by Roberto Ierusalimschy, "lpeg.Ca(patt) - "accumulates" the nested captures." (http://www.inf.puc-rio.br/~roberto/lpeg/slides-lpeg-workshop2008.pdf ) Is this obsolete, has it been replaced by anything? 2. How can I check if a string begins with a class of words "(Der |Die |Das |The |An )" etc. and strip these words from the string? I do it with a compiled regexp in python, but "Programming in lua" has this to say: "Unlike some other systems, in Lua a modifier can only be applied to a character class; there is no way to group patterns under a modifier. For instance, there is no pattern that matches an optional word (unless the word has only one letter). Usually you can circumvent this limitation using some of the advanced techniques that we will see later." I haven't found these techniques yet. 3. How can I compare strings with utf8 characters? My naive approach if string.find(record, "Résumé") doesn't appear to work (while the same method does work if the string has only ASCII characters). Sorry if this is OT, and I'll be grateful for any pointers. Thomas

backgrounds: help needed #2
by Peter Münster 29 Jan '09

29 Jan '09

Hello, Since I've not found the answer yet, I repost the problem: I need some text with background, that can break across lines. But the background must not touch the background of the next line! \setupcolors[state=start] \starttext inframed does not allow linebreaks: \def\Bla{\inframed[background=color, backgroundcolor=gray, frame=off, offset=overlay, backgroundoffset=2pt, location=keep]{% FF FF XX XX XX XX XX XX SS CS CS}} \dorecurse{20}{bla \Bla\ bla} And textbackground does not allow to seperate the backgrounds of 2 lines: \definetextbackground[TG][backgroundcolor=gray, frame=off, offset=overlay, backgroundoffset=2pt] \def\Bla{\starttextbackground[TG]FF FF XX XX XX XX XX XX SS CS CS% \stoptextbackground} \dorecurse{20}{bla \Bla\ bla} \stoptext Could anybody help please? TIA for any hints! Cheer, Peter -- http://pmrb.free.fr/contact/

Composed Words
by Matthias Wächter 29 Jan '09

29 Jan '09

Greetings, First question: I thought that composing words using || should break after the hyphen/dash, but for whatever reasons, this does not always work correctly and breaks such that the hyphen/dash is in the next line — see attached picture. Processed by luatex, updated today. The source code is not fancy in any way: \language[de]% %[…] Die Ausgabe einer komplexen Netzwerkkomponente wie einem TTEthernet||Switch kann am leichtesten von einer einfachen Vergleichsschaltung überprüft werden, wenn die paarweise angeordneten Komponenten Bit für Bit synchron arbeiten %[…] Second question: Why did you choose the «En dash» as the default intra word dash for at least English and German, whereby this is wrong in most cases and should be the hyphen instead? http://en.wikipedia.org/wiki/Dash#En_dash lists the uses of the En dash. It is limited to number ranges, relationships and connections and compound adjectives. for me, \setuphyphenmark[sign=normal] fixed the issue, but the “correct” way (hyphen) should be the default, IMHO. – Matthias

combination
by Nicolas Luchier 29 Jan '09

29 Jan '09

Hello, I searched the mailing archive but found nothing about my problem. I have 3 figures to put into combination 2*2. The way it is handle it that the third figure is place below the first one, which is quite logical. I'd rather have it centered in the second row. Is there any mean to do this ? I didn't find a clue anywhere. Thank you. Nicolas
