But tex.print removes the \par, perhaps because of | Each string argument is treated by TEX as a separate input line. Also interesting: | The very last string of the very last tex.print() command in a | \directlua will not have the \endlinechar appended, all others do. But a statement about \par filtering of tex.print() would be useful for the documentation. Minimal example (luatex --ini): \catcode`\{=1 \catcode`\}=2 \expandafter\def\expandafter\x\expandafter{% \directlua{tex.print('a \par b')}% }\show\x \csname @@end\endcsname\end Result: "a b" Yours sincerely Heiko Oberdiek

Proposal for a change in otfl-luat-dum.lua
by Beingalink 21 Feb '11

21 Feb '11

To be able to use fonts inside a dfont archive (Helvetica for example) I had to change line 59 in otfl-luat-dum.lua to " dfont = "truetype fonts",". When I updated my mactex 2010 installation a few days ago, the file got overwritten and I had to do the change again. I'm not sure if there is a better/cleaner solution but since this small change works for me, this could at least be used as a temporary fix.

mediabox accuracy
by Peter Rolf 19 Feb '11

19 Feb '11

Hi, I have a preflighting problem caused by a badly rounded (too small) mediabox. This following snippet is taken from that pdf. 93 0 obj << /Type /Page /Contents 94 0 R /Resources 92 0 R /MediaBox [0 0 923.24 585.99] /TrimBox [ 0.0000 0.0000 923.2440 585.9925 ] /CropBox [ 0.0000 0.0000 923.2440 585.9925 ] /Parent 98 0 R >> The mediabox accuracy is swayed by \pdfdecimaldigits (here \pdfdecimaldigits=2), while the other boxes use a fixed accuracy (four points after the digit). I see two solutions: 1. use the same fixed accuracy for all boxes 2. use the same accuracy given by \pdfdecimaldigits for all boxes I guess the second solution can still cause problems due to runtime changes of \pdfdecimaldigits (unless this is a 'write once' register) Test file (ConTeXt) is attached. Tested with trunk beta-0.65.0-2011010308 (rev 4050) and beta-0.66.0-2011021618 (rev 4086) on Windows Vista. Peter

Problem using dfont fonts with lualatex (Mactex)
by Beingalink 10 Feb '11

10 Feb '11

I get following error message: ----------------------------------------------------------------------------------------------------------- ! LuaTeX error ...0/texmf-dist/tex/luatex/luaotfload/otfl-luat-dum.lua:67: bad argument #2 to 'find_file' (invalid option 'truetype dictionary'). <to be read again> \scan_stop: l.112 ...=MatchLowercase,Ligatures=TeX]{Helvetica} ----------------------------------------------------------------------------------------------------------- Google told me that this might be related to code that originally came from context but wasn't changed to work with luatex. But I'm not sure since I'm not a developer. If there's sth. I can do to identify/fix the bug, please don't hesitate to tell me. Regards, Tobias Link
