Trouble with hyphenation.
by Paul Isambert 19 Feb '12

Hello all, I've found some strange behavior with hyphenation; but since hyphenation has been discussed frequently, and might involve some settings in conf files somewhere I'm not aware of, I wouldn't like to submit an unnecessary tracker item in case the problem is well known. The code is: \hsize=0pt \overfullrule=0pt \hyphenation{W-h-a-t-e-v-e-r} \uchyph=1 Acceptation Behavior Dying Expression Whatever \uchyph=0 Acceptation Behavior Dying Expression Whatever \bye And comparing the plain TeX compilation in PDFTeX and LuaTeX (all from TL2011, except LuaTeX, which is rev 4358), I notice that: - LuaTeX doesn't obey \uchyph=0; it does hyphenate the words, although not as completely as when \uchyph=1. - "Acceptation" is hyphenated in LuaTeX even though it's the first word, and a hyphenable word should be preceded by a glue (see TeXbook p.256); it is not hyphenated in PDFTeX. - As shown by the hyphenation of "Whatever", LuaTeX disregards \lefthyphenmin and \righthypenmin. Does it ring any bell, or should I add it to the tracker item? Best, Paul

Has the development stopped?
by Christoph Pohl 17 Jan '12

Hello, I’ve noticed that there hasn’t been any SVN activity since October. Is this some sort of "scheduled break" or did you loose interest? I think luatex is an awesome idea, and I’m really grateful for all the great work you guys have done so far. It would be a real tragedy if it never reaches 1.0. I’m not sure I can help with the actual coding, but I’d love to help out with if I can. Cheers Christoph

string.explode()
by Reinhard Kotucha 02 Jan '12

02 Jan '12

Hi Taco, though luatex isn't frozen yet, I think that many people are using it already and drastic changes are not desirable. There is one thing which could probably be improved without breaking existing scripts, as far as I can see: string.explode(foo, ' +') expects that ' ' is a space token (ASCII 0x20). Is it possible to change string.explode() so that ' ' can be either a space token (ASCII 0x20) or a tabulator (ASCII 0x09) without breaking existing scripts?

Memory allocation bugs?
by Vianney le Clément 02 Jan '12

Hello, Recently, I have run into strange error messages using plain luatex. I have narrowed it down to some minimal examples shown below with their log. I have tried luatex provided by texlive 2011 and a build from the latest svn trunk. They work fine with pdftex. They also work fine (apart from luatex being unable to ship the huge page) when removing the \font\temp=... line in the loop. In case you wonder, my intent is not to put 10k lines on one page, it just simplifies the examples. I also get the errors when spreading out the text across multiple pages. Can you put me in CC of the replies as I'm not subscribed to the list? Thanks.
