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)

letterspacing and (no) ligatures
by Robert 17 Sep '11

17 Sep '11

Hi, here are two bugs: * in pdftex, \letterspacefont does not disable the ligatures, but this is what happens in luatex. * neither \tagcode nor \pdfnoligatures seem to have any effect (for non-letterspaced fonts, that is). Example: \input luaotfload.sty \font\x="Latin Modern Roman:+liga;+tlig" at 12pt \tagcode\x`\f=-1 % no effect \pdfnoligatures\x % ditto \x fi -- \letterspacefont\y\x 100 % killing the ligatures \y fi -- \bye Best regards, -- Robert

Don't update to Mac OS X 10.6.7
by Mojca Miklavec 27 Apr '11

27 Apr '11

Hello, I'm sorry for cross-posting, but this issue is a really nasty one (and might come too late for some). If you use OpenType fonts in your TeX documents, don't update your Mac OS X unless you want to have some serious fun with printing ... http://reviews.cnet.com/8301-13727_7-20048314-263.html http://discussions.apple.com/thread.jspa?threadID=2792142 http://discussions.apple.com/thread.jspa?threadID=2791830 ... a workaround that worked for me (for PostScript printers only) was the following: I used http://localhost:631/help for help and ended up doing lpstat -p to get printer name and then lp -d some_very_weird_printer_name_ myfile.pdf to send the file to a PostScript printer. I wasn't sure whether it was an OS issue or LuaTeX issue (I updated both), but Florian on ntg-context mailing list posted the above links which most probably makes XeTeX users vulnerable as well.
