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)

Beste lezers, Deze week worden beide harde schijven van de NTG server vervangen als onderdeel van het reguliere onderhoud. Als gevolg daarvan zal de gehele machine (alle email lijsten en websites) vanaf woensdagmiddag tot donderdagochtend onbereikbaar zijn. We doen ons best om alle services weer zo snel mogelijk aan de praat te hebben. --- Dear readers, This week both of the harddisks of the NTG server will be replaced as part of regular maintenance. Consequentially, the whole machine (including all mailing lists and websites) will be unreachable from Wednesday afternoon through Thursday morning. We will do our best to get all services back up as soon as possible. --- Best regards, Taco Hoekwater Elvenkind Hosting

I tried debugging it but it was too much complex doing many clever things. The rewrite is partly stolen from XeTeX one, further improved and is much simpler and had no regressions AFAICT. This might fix #726 and other potential issues. ------------------------------------------------------------------------ r4362 | khaled | 2012-02-29 20:14:09 +0100 (Wed, 29 Feb 2012) | 1 line Changed paths: M /trunk/source/texk/web2c/luatexdir/tex/mlist.w Handle the case where the box can't be stretched as much as we want ------------------------------------------------------------------------ r4363 | khaled | 2012-02-29 20:14:32 +0100 (Wed, 29 Feb 2012) | 6 lines Changed paths: M /trunk/source/texk/web2c/luatexdir/tex/mlist.w Use the actual width of the accented box when building extensible accent Previously it took delimiter_shortfall and delimiter_factor into account but it does not confirm with the behaviour of MS implementation, nor plain TeX's hackish \overbrace nor non-extensible accents. It seems to have been used to workaround brokenness of get_delim_box(). ------------------------------------------------------------------------ r4364 | khaled | 2012-02-29 20:15:15 +0100 (Wed, 29 Feb 2012) | 1 line Changed paths: M /trunk/source/texk/web2c/luatexdir/tex/mlist.w Fix #689 ------------------------------------------------------------------------
