Warning re comparing Word and TeX
by c.a.rowley＠open.ac.uk 02 Nov '09

02 Nov '09

Hi guys Do not forget that Word etc have a different model for microtypography and how they treat font metrics and 'normal horizontal stacking' of glyph sequences. The big difference that has a major effect on how math layout is acheived is that they do not use the concept of nested boxes: everything is simply 'positioned glyphs'. There are other important differences but they are not so likely to affect math typesetting. If you get Windows 2010, I think that all the math stuff is available 'at the OS level' which I think means that it is also all in an Active-X control for developers use. But probably with zero documentattion! Finally, if you want to know about their algorithm, just ask them! Although they may reply, as I would about details like that, 'we have forgotten'. Cheers, chris > > Office 2007 seems to handle sub/superscripts of big operators > differently; superscript is placed immediately after base glyph while a > negative kern equal to italic correction is inserted between base and > subscript i.e. the reverse of what is described in the spec, and math > kerning is ignored completely. Big sigh. I'll see if I can get my hands on a copy of Word2009.

I'll rethink this. Office 2007 seems to handle sub/superscripts of big operators differently; superscript is placed immediately after base glyph while a negative kern equal to italic correction is inserted between base and subscript i.e. the reverse of what is described in the spec, and math kerning is ignored completely. So I think the current positioning of superscripts is correct, only subscripts need to be fixed, though I'm not really sure about any of those conclusions :) Regards, Khaled -- Khaled Hosny Arabic localiser and member of Arabeyes.org team Free font developer

Luatex 0.44.0 announcement
by Taco Hoekwater 02 Nov '09

02 Nov '09

Hi, I have just uploaded the archives for a new luatex release, 0.44.0. There are not a lot of new features yet, but this releases fixes a fair amount of bugs found in 0.43.0 (and earlier versions). New features: * libpng is now 1.2.40. * hlist nodes now have a subtype to distinguish hlists generated by the paragraph breaking, explicit \hbox commands, and other (as-yet-undefined) sources. * \pdfobj now has an extra optional keyword: 'uncompressed', which forces the object to be written to the PDF in plain text (see the manual for the exact details). * The lua file from the luamd5 library (which provides the md5.hexsuma() function) is now embedded in the executable. Bug fixes: * \latelua now works in DVI mode again. * status.output_file_name could crash when used too soon. * In 0.43, rules were not output at all in DVI mode. * \leavevmode\penalty-10000\penalty-10000 crashed luatex. * the API of margin kern nodes to lua was using the wrong fields in the nodes. * A few fixes to the manual. * PDF Xref stream dicts were slightly non-conformant. * There was too much space between two consecutive math displays (this bug was inherited from Aleph) * Synctex was broken (thanks, Akira) * Font mark classes were handled incorrectly by the fontloader code. * There was a crash possible with certain types of named PDF destinations. * Math delimiters and large operators in new MATH fonts no longer apply the italic correction (this fixes placements of super- and subscripts on such items for those fonts). * The converter from lua strings to token lists (for the node interface) sometimes generated invalid tokens. * CFF (OpenType) fonts now listen to 'embedding="full"'. TTF is still todo. * Font tables with 'embedding="no"' would cause luatex to crash. * \pdfobj file {} failed to find the file if there was no lua callback in place. * An optimization in MS Mincho caused luatex to crash. The archives can be downloaded from supelec as usual: http://foundry.supelec.fr/gf/project/luatex/ You could also check out the sources via anonymous svn: svn co http://foundry.supelec.fr/svn/luatex/tags/beta-0.44.0 Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

echoing system call argument to stderr
by T T 01 Nov '09

01 Nov '09

Hi, I've noticed that os.execute under texlua echos its argument to stderr. This is not the behaviour under the standard lua interpreter. Is it a bug or feature (and what would be the reason for it)? Cheers, Tomek

kpse.find_file
by Reinhard Kotucha 01 Nov '09

01 Nov '09

Hi, I just fixed some nasty bugs in texlua wrappers for ppower4 and pdfthumb which are under texmf-dist/scripts in TeX Live. There are no problems on Windows: When I type "ppower4 --help", I get PPower4 [-v|-n|-h|-V|--verbose=<n>|--nocompress|--help|--version] infile outfile On Unix, however, I get a warning message: warning: kpathsea: configuration file texmf.cnf not found in these directories: [...] Here is [...] with colons replaced my linebraeks: /usr/local/texlive/2009/texmf-dist/scripts/ppower4 /usr/local/texlive/2009/texmf-dist/scripts /usr/local/texlive/2009/texmf-dist /usr/local/texlive/2009/texmf-dist/scripts/ppower4/share/texmf-local/web2c /usr/local/texlive/2009/texmf-dist/scripts/share/texmf-local/web2c /usr/local/texlive/2009/texmf-dist/share/texmf-local/web2c /usr/local/texlive/2009/texmf-dist/scripts/ppower4/texmf-local/web2c /usr/local/texlive/2009/texmf-dist/scripts/texmf-local/web2c /usr/local/texlive/2009/texmf-dist/texmf-local/web2c /usr/local/texlive/2009/texmf-dist/scripts/ppower4/share/texmf/web2c /usr/local/texlive/2009/texmf-dist/scripts/share/texmf/web2c /usr/local/texlive/2009/texmf-dist/share/texmf/web2c /usr/local/texlive/2009/texmf-dist/scripts/ppower4/texmf/web2c /usr/local/texlive/2009/texmf-dist/scripts/texmf/web2c /usr/local/texlive/2009/texmf-dist/texmf/web2c ...and pp4p.jar is obviously not found, Java then prints its own usage message. It seems that texmf.cnf is searched in texmf-dist only, but how can this happen? Strange enough, everything works fine on Windows. I can strip down the texlua script: ------------------------------------------------------------------ #!/usr/bin/env texlua if os.type == 'windows' then kpse.set_program_name('ppower4.exe', 'ppower4') else kpse.set_program_name('ppower4') end jarfile=kpse.find_file('pp4p.jar', 'texmfscripts') print (jarfile) ------------------------------------------------------------------ On Windows it returns /path/to/pp4p.jar, on Unix it returns "nil". The command kpsewhich -format=texmfscripts pp4p.jar returns the correct path on both, Unix and Windows. Hence, I think it's a LuaTeX problem. I don't think that fixing this problem is urgent. It's definitely not worthwhile to delay a TeX Live release. Karl, I can provide a simple solution for the time being: Because what we have in TeX Live already works as expected on Windows, we only need a solution for Unix. I could simply copy the shell scripts we had in TeX Live 2005 to texmf-dist/scripts/ppower4 and adapt the symlinks accordingly. Then everything works on all platforms. What do you think?
