Snapshot 20070307
by Taco Hoekwater 10 May '12

10 May '12

Hi all, I decided to do a snapshot now instead of waiting for friday, because I want to start concentrating on something else besides font support issues. What's new: * Non-CID PostScript-based Opentype fonts are now combined over the entire document, and properly subsetted. The code is borrowed from xdvipdfmx with some minor adjustments Adding support for CID-keyed OpenType fonts would not be hard but at the moment I lack example input (and incentive). * A small extension to the virtual fonts structure: you can use f.fonts[1] = { 'id' = 38} to do a backreference to a previously defined font. This saves quite a few computations * There was a bug in the handling of \leaders in the output whereby it's width was taken to be twice what it should be while writing to the PDF, fixed now. * The font inclusion code is cleaned up a bit by Hartmut. * Some compilation problems were fixed. * There is (quite a bit of) debugging information printed out when OTPs are in use, because I am tracking down a bug reported by Idris. The input of each and every OTP step is shown on the terminal in a line line this: [57902][1568][58423][1568][58408][1568][58921] those are the decimal values of ocp i/o characters. If you don't need them, don't worry about it. Happy TeXing, Taco ----- Downloading and installation details: If you go to https://foundry.supelec.fr/frs/?group_id=10 you will see that there are three new released files: * luatex-snapshot-20070307.tar.bz2 This is the source tree. * luatex-snapshot-20070307-win32.zip A cross-compiled (mingw) windows binary. This is a web2c based binary, so it needs a texmf.cnf file (It will NOT work if you have only miktex installed). * luatex-snapshot-20070307-linux-i386.tar.bz2 An intel 32 linux binary (2.6.17)

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

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

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.
