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)

A native support for SVG
by TeXWorld 18 Apr '09

18 Apr '09

Hello, I'm a ConTeXt (and LaTeX too) user. When I want to make a vector picture, I'm trying most of the time to use programs who can export PGF/TikZ or PStricks. A lot of users like me don't "program" their vector pictures and use wysiwyg programs like Inkscape or Illustrator to generate PStricks ou PGF/TikZ code. Of course whatever program used, we can find a SVG export. SVG is the most spread and the most used format to store vector pictures. I request a native support for SVG in XeTeX and in LuaTeX, I think it would be a great thing. Of course when I want to include SVG pictures in my documents I can convert them to pdf before but the problem is that labels and texts won't be compiled : fonts will be wrong. What do you think about this ? Do you think it's something possible ?

Help with fonts needed
by Taco Hoekwater 10 Apr '09

10 Apr '09

Hi all, The next big release of luatex will be about (opentype) math. One of the prerequisites of that is the ability to handle the opentype math features, and that means updating the embedded fontforge code. This is what I am currentlu working on. While updating the fontforge.to_table() code, I noticed that there where still some todo items in the source and it would be nice if these could be resolved as well. If have written tentative code for those now, but I do not have the fonts to go with the code so it is not at all unlikely that there are crash-level bugs and/or misconceptions. In order to make luatex even better, I need your help finding good examples of each of the following font types: * Apple dfont collections * AAT fonts in all forms * Apple Multiple Master (AAT "fvar") * Adobe's Type1-based Multiple Master * Fonts specifying baseline settings (OT "BASE" | AAT "bsln" ) * Fonts specifying justification data (OT "JST" | AAT "just") Please drop me a line if you can help out with any of these... Best wishes, Taco

Modifying the LuaTeX Engine
by وفا خلیقی، Vafa Khalighi 30 Dec '08

30 Dec '08

Now it has been some time that I have been studying the TeX-e-Parsi engine and have studied the changes that they have done in the actual TeX engine. TeX-e-Parsi is a localised version of TeX which has perfect bidirectional support and I hope that we can make these changes in the LuaTeX engine so we have perfect bidirectional support. TeX-e-Parsi adds about 100 Prmitive commands to the Original TeX primitive commands. I think we would not need all of these 100 commands but we will need the commands that have something to do with the directions. These extra 100 commands are: \LtoR, \RtoL, \accfactor, \activefont, \aftereverydisplay, \autoLRdirset, \autofontset, \autoLRset, \basefont, \billions, \everysemidisplay, \everysemimath, \everysemipar, \fonttwin, \hboxR, \ifLtoR, \ifRtoL, \ifautoLRdir, \ifautofont, \ifjoinable, \iflatin, \ifleftvbox, \ifcase, \ifonesof, \iftensof, \ifhundredsof, \ifthousands, \ifmillions, \ifbillions, \ifprehundreds, \ifprethousands, \ifpremillions, \ifprebillions, \ifsetlatin, \ifsetsemitic, \ifsetrawprinting, \ifsemiticchar, \ifsplited, \inputR, \jattrib, \lastcharjoinable, \lastcharunjoinable, \latin, \lcode, \leftvbox, \curboxdir, \curdirection, \curLRswch, \curspeech, \maketwin, \manLRset, \midruleinit, \midrulespec, \millions, \openinR, \openoutR, \rawprinting, \eqprinting, \rightvbox, \leftinput, \semiaccent, \semiaccentdown, \retainaccentchar, \semichar, \semichardef, \semiday, \semifam, \dblfont, \semifont, \semihalign, \semimonth, \semispaceskip, \semitic, \semixspaceskip, \semiyear, \thousands, \twinfont, \vboxjustification, \LRshowswitch, \LRmiscswitch, \eqwrite, \letlatinname, \letsemiticname, \leteqname, \eqchar, \eqcharif, \letnoteqname, \letnoteqchar, \letnoteqcharif, \endspecial, \beginspecial I am attaching the actual change file (tex.ch) with this email. would wou think that we could possibly define these new primitives in the LuaTeX engine? if you do that, then there will be no problem at all with bidirectional typesetting and LuaTeX will have most complete bidirectional algorithm for typesetting in TeX. Please feel free to comment about the commands. Thanks I trust my family jewels only to Linux _________________________________________________________________ Net yourself a bargain.

> Can you do these in luatex as well? Yes, but please give me some time. Let me first produce the document which explains TeX-e-Parsi's changes. At first glance: From the pdf's I do > not see anything that Omega could not do with ease 8 years ago. See the > attached from a journal done in luatex. The fact is, " I did not typeset them, those files just were some sample files already being there." Yes, the output you have sent looks super good. I think this is not a good way of comparing outputs. We should have a sample complex bidirectional text which contain everything in it (boxes, LTR and RTL texts, poems, colors, diagrams, footnotes and ...) and then compare the produced outputs. Please also note that I am using LaTeX not context. _________________________________________________________________ Time for change?

Luatex beta 0.31.0
by Taco Hoekwater 30 Dec '08

30 Dec '08

Hi all, I have just uploaded the archives for luatex 0.31.0. This is just an intermediate release so that some testing can be done on the updated fontforge embedding. * There are new fields being generated by fontforge.to_table(), and one or two old ones have been removed. These fields are / will be documented in the manual, but very briefly: - MATH table and associated information are now exported (the main reason for the new fontforge code) - Baseline data is now exported (perhaps usable in lua code) - Multiple Master / Glyph variation data is now exported (but useless, for now) - Mac Feature (AAT) information is now exported (perhaps usable in lua code) - If (lookup) names were saved via the PfED table, these will the exported instead of the default, generated names. (as requested by Yannis) * dfont is now treated as an archive format just like ttc when it comes to fontforge.info(). NOTE: that does not mean you can actually use them, because the backend doesn't know yet how to embed dfont fonts in the PDF, that is on the TODO list for the next big beta (0.40.0). * The executables are a lot larger than before. That is because much more of fontforge is included than before. Likely this will stay this way, because this makes upgrading the ff code much easier, and it means that luatex/FF potentially understands more font formats (after upgrading the backend, of course) The archives (just binaries this time) can be downloaded from supelec as usual: http://foundry.supelec.fr/projects/luatex/ If you need the sources, please check out via anonymous svn: svn co svn://scm.foundry.supelec.fr/svn/luatex/tags/beta-0.31.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco _______________________________________________ dev-luatex mailing list dev-luatex(a)ntg.nl http://www.ntg.nl/mailman/listinfo/dev-luatex

OTF engine in LuaTeX
by Elie Roux 29 Dec '08

29 Dec '08

Hello, I have a small experience in TeX (I wrote a plain TeX style for gregorian chant, http://home.gna.org/gregorio), and I am very interested in LuaTeX and all the features it will bring to the TeX world. For example LuaTeX allowed me to correct some very annoying bugs that happened sometimes in my style, and that couldn't be corrected in plain TeX. So thank you for you great job! It happens that I have some time now, and during next month. So I would be interested in helping you, especially for OTF integration in LuaTeX. For now I'm using the code present here http://luatex.bluwiki.com/go/Use_a_TrueType_font to deal with OTF, but it's not really satisfying (no ligatures for example). So if it is possible to help with an OTF engine like in XeTeX, I would be very happy to start it, or continue it. Please tell me how I should proceed! Thank you in advance, -- Elie
