Snapshot 20070307

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)

Some suggestion for dynamic allocation...
by David Kastrup 29 May '07

29 May '07

I have seen in the recent ChangeLogs code changes that basically do a realloc of array structures and stuff. realloc with a fixed increment is basically O(n^2) (it becomes O(n) for a fixed growth percentage). Anyway, I seem to remember that the basic Pascal compiler implemented by web2c actually _has_ new, delete, and pointer types. Maybe it would be saner to just scrap the array indexing stuff and replace it with the normal dynamic allocation that the libraries are optimized for? There is going to be some amount of waste since new/delete are mapped to malloc/free, and those store the size of the allocated block before it, while Pascal has the required size information available at the time it calls delete. However, I think that the resulting memory bloat might likely be offset by the advantages of using a more "native" memory access model that tends to be better matched to the operating system and its libraries. The main problem I see is dealing with dumping a format, since then the memory is indeed being accessed as a sequential array. -- David Kastrup

[Fwd: [Supelec-Foundry] Maintenance]
by Taco Hoekwater 29 May '07

29 May '07

Forwarded for your information. Best wishes, Taco -------- Original Message -------- Subject: [Supelec-Foundry] Maintenance Date: Tue, 29 May 2007 10:47:04 +0200 From: noreply(a)foundry.supelec.fr To: taco(a)metatex.org Hi, In order to prepare an upgrade of Supelec Foundry harware/software, the server will be unavailable today from 14:00 to 16:00 (expected) (locatime, GMT+1). There has been one alert on harddisk, so we will install a new one before the situation gets worse. Also the sofware is currently base on RedHat-FC3 and GForge 4.1. Current version is GForge 4.5 and we would like to run it on RedHat-FC6. The plan is to : - add the new HDD - install RedHat-FC6 on the new HDD - install GForge 4.5 - migrate all the user files This will be done in several steps. Expect a longer shutdown of the server in the newt few weeks. Best regards and sorry for the inconvenience. Fabrice Popineau

Sounds like the idea we talked about in ... somewhere ...?? So is this an arbitrary dictionary (list of name, value pairs? > An attribute is an item that becomes attached to the actual nodes > that are to be typeset. But what is a `node to be typeset'? Or is this deliberately vague? Anything in an hlist or vlist? Or only character(/glyph??) nodes? Thanks chris

Speed of latest revisions
by Oliver Heins 23 May '07

23 May '07

I'm not sure whether this is of any importance. If not, please just ignore this mail. I noticed that the latest revisions (441/442) are very slow. I just switched back to rev 339, which runs much faster (approximated 10 times). Regards, olli

lineno.sty doesn't work, problems with MinionPro.sty
by Oliver Heins 22 May '07

22 May '07

I'm not sure if this is the right time to report these problems. Don't hesitate to tell me to shut up if it ain't :-) lineno.sty doesn't seem to work with luatex (rev. 439). it complains that some font metrics are not found and doesn't set any line numbers. | ! Font T1/cmr/m/n/5=ecrm0500 at 5.0pt not loadable: Metric (TFM/OFM) | file not found or bad. | <to be read again> | relax (Same with ecss0500 at 5.0pt and ecsl1000 at 10.0pt) With MinionPro.sty there are some interesting problems which are hard to describe and are probably best shown by example: % ----------------------------------------------------- \pdfoutput=1 \documentclass[a4paper,10pt]{scrbook} \usepackage[T1]{fontenc} \usepackage[english]{babel} \usepackage{MinionPro} % comment this out \usepackage{ledmac,blindtext} \makeatletter %% Outputroutine \renewcommand*{\do@linehook}{% \latelua0{ pageno = 1 }} \makeatother \linenummargin{outer} \begin{document} \beginnumbering \pstart \blindtext[3] \pend \endnumbering \end{document} % ----------------------------------------------------- I'm just playing a bit with the output routine; do@linehook is a hook of ledmac in its otr. Oddly enough, everything works fine when \usepackage{MinionPro} is commented out. Regards olli
