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)

luatex and hyphenation patterns
by Norbert Preining 01 Nov '07

01 Nov '07

Hi all! One user of Debian wanted to build a luatex based latex format (he wanted to test some examples from the luatex.org documentation slides, using the old \lua{...} code, anyway). Unfortunaltely this will not work in any way because there are so many hyphenation patterns using non-ascii and non-utf8 content. All those of course break. Is there any suggested way how to cope with this?

snapshot 2007-10-29 released
by Taco Hoekwater 29 Oct '07

29 Oct '07

Hi, As I promised yesterday, snapshot 2007-10-29 is now released. Note that this is a snapshot only, not a proper beta. There are some known problems, even though the test documents now seem to run properly. News compared to the last beta (0.11.2): * Completely overhauled hyphenation and ligkern application. There is a new chapter in the manual to document all the changes to the hyphenation and line breaking algorithms, it is simply too much to list here. * the interface of the pre_linebreak_filter,hpack_filter, vpack_filter, and pre_output_filter has changed slightly. * lpeg is now at version 0.7 * a whole series of exotic bugs and compiler warnings are fixed thanks to the watchful eye of Fabrice. * texio.print now accepts multiple strings as arguments. * The lua function os.sleep() is added I have uploaded source and linux/windows 32 binaries to http://foundry.supelec.fr/projects/luatex/ Have fun, Taco

Wow! > * to switch from hyphenating glyphs to hyphenating characters That's the best news I have heard in many a long decade! I would be very interseted in reading the documentation for such innovations (or even to help writing it ... oops, what am I saying???). > * to remove the language-related limits Examples? Thanks chris

friday news
by Taco Hoekwater 28 Oct '07

28 Oct '07

Hi, Sorry, I had hoped to do a snapshot today, but the code is not really ready yet. There one big bug expecially that I want to fix: halfway through typesetting the reference manual it starts producing empty pages. Since the manual is supposed to explain what is new, this is pretty serious. I now hope to tackle that bug over the weekend, with a snapshot on monday. Sorry for the continuous delays, Taco
