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)

(fwd) Bug#441595: not all libraries are customized, there is room for improvement
by Norbert Preining 28 Nov '10

28 Nov '10

Dear Taco, one of the lua Gurus here at Debian checked the embedded libs and found that most of the included libs are very similar to upstream, and he offered to push the few changes in your code to upstream. What do you say? (See attached email, including the diffs between current upstream of the lua libs and code in texlua).

negative protrusion values
by Robert 24 Sep '10

24 Sep '10

Hi, luatex doesn't deal with negative protrusion values correctly -- for opentype fonts, the margin kern is too small, while for type1 fonts it's way off, and even in the wrong direction: \tracingoutput1 \showboxbreadth\maxdimen \showboxdepth\maxdimen % Opentype: \input{luaotfload.sty} \font\x="Latin Modern Roman" at 12pt % Type1: % \font\x=cmr12 \x \pdfprotrudechars2 \parindent=0pt \lpcode\x`N=-500 \rpcode\x`N=-500 \lpcode\x`Z= 500 \rpcode\x`Z= 500 H\hfill H\penalty-10000 N\hfill N\par H\hfill H\penalty-10000 Z\hfill Z\par \bye Regards, -- Robert
