Hello, > please feel and change the code on the Wiki, that's the whole of > having a public Wiki... Yes, of course. I was thoughtless. > have you tried to apply the corrections? I have. The wiki example is now corrected, although I have not added any code for ligatures. Although I have code that works, it is very hackish and most likely will not suffice for more than simple f-f/f-f-i ligatures. I of course can post my OTF code to the wiki, but caveat emptor ;-) Jonathan

How to use an OpenType font.
by Javier Múgica 01 Oct '08

01 Oct '08

I am trying to use an open type font. In the manual I can see a piece of Lua code for loading such a font. I "suppose" that I have to enclose it within \direclua0{}, so I wrote \directlua0{function load_font (filename) local metrics = nil local font = fontforge.open(filename) if font then metrics = fontforge.to_table(font) fontforge.close(font) end return metrics end } \directlua0{twelverm = load_font('C:/Windows/Fonts/LMRoman12-Regular.otf')} but it still does not solve the problem. I have no idea of how to make the font known for TeX. This is command is expandable. As an example, the following input: $\pi = \directlua0{tex.print(math.pi)}$ will result in p = 3.1415926535898 But this leaves me none the wiser about fonts. The problem is: which is the equivalent of \font\tenrm=cmr10 for OpenType (or TrueType) fonts? This problem is present to some extent all troughout the manual. It seems as if you were taking always something for granted about the interaction between Lua and TeX that is not explained anywhere. You may find it obvious, but keep in mind that manuals are intended for people who still don't know. For somebody like me who comes from TeX, the impression got when reading the manual (or at least the impression I had) is as having all the pieces from a conglomerate rock but not having the cement. And the lack of examples is exasperating. This I understand given the development state of the program, but men, since one of the main features of LuaTeX is accesing and modifing the TeX parameters and state with Lua code, some exemples of this, even if kept to a minimum, would be very helpful. I wouldn't have any problem in taking the time to write them myself... if knew it, but the LuaTeX manual is still very far from serving to the learning of LuaTeX in the same way as the TeXBook serves for the learnig TeX or "the red book" serves for the learning of the postscript language. Continuing with my problem with using an otf font, I found some pages below in the manual an example intended for a diferent purpose but that looked usefull for solving my problem even if not the way it should be done. So below the avobe mentioned lua code I boldly wrote \directlua0 { callback.register('define_font', function (name,size) if name == 'LMRoman12-Regular' then f = twelverm else f = font.read_tfm(name,size) end return f end ) } \font\twelverm= LMRoman12-Regular it does not work, but it exhibits a bug in LuaTeX: I get a warning at \dump time: luaTeX warning: lua-loaded font [1] (<NULL>) has no character table! but right afterwards the program dies and is closed by Windows. --Javier A.

Luatex beta 0.30.0 released
by Taco Hoekwater 30 Sep '08

30 Sep '08

Hi all, I have just uploaded the archives for luatex 0.30.0. This release matches SVN revision #1521. New features: * Readable \tex internal params that are counts, attrs, or dimens are now returned as numbers instead of strings, and skips as node objects. Read-write access to tex's skip registers added: tex.skip[0] etc. * new callback: 'linebreak_callback' to replace the internal paragraph breaking code * the tex table now supports more readable 'convert' values: tex.fontname, tex.pdffontname, tex.pdffontobjnum, tex.pdffontsize, tex.uniformdeviate, tex.number, tex.romannumeral, tex.pdfpageref, tex.pdfxformname (each takes a number as argument) * new readable parameter: tex.fontidentifier(number) returns the \csname associated with that font id * luatex now outputs \FONT<nr> instead of \^^@ in Overfull/Underfull messages if the font's id text is zero (like for expanded fonts) (#77) * luatex --version is split into --version and --credits * There is now (again) an svn revision number in luatex --version (#91) * Add support for more read-only internal access from lua: tex.lastpenalty, tex.lastkern, tex.lastskip, tex.lastnodetype, tex.inputlineno, tex.badness, tex.pdftexversion, tex.pdflastobj, tex.pdflastxform, tex.pdflastximage, tex.pdflastximagepages, tex.pdflastannot, tex.pdflastxpos, tex.pdflastypos, tex.pdfrandomseed, tex.pdflastlink, tex.luatexversion, tex.Alephversion, tex.Omegaversion, tex.Alephminorversion, tex.Omegaminorversion, tex.eTeXminorversion, tex.eTeXversion, tex.currentgrouplevel, tex.currentgrouptype, tex.currentiflevel, tex.currentiftype, tex.currentifbranch, tex.pdflastximagecolordepth (#81) * the old --src-specials are replaced by --synctex (#63) * the \expanded primitive is backported from pdftex 1.50 (#43) * luatex now comes with libpng 1.2.32 * experimental: tex.definefont(string, number) associates a csname string with a font id number Bugs fixed compared to 0.29.0: * dashes were exported wrongly by MPlib * multi-item \discretionaries were broken in various ways (#78, mailinglist) * read_font_info was sometimes called recursively from lua-loaded virtual fonts * do_vf was sometimes called on lua-loaded fonts that where already known to be virtual * trailing junk in tfm files is now ignored (needed for ecrm fonts) * pdf_ignored_dimen was initialized too late, breaking \prevdepth handling and causing output lines to overlap eachother (#72) * pdf.immediateobj() had a printf-related bug * the fontname terminal logging is fixed for strange font file names * lua tex array assignments now listen to the globaldefs setting (tex.count[0] etc) (#92,partial) * \parshape was broken (#70) * there is no longer a ".tex" extension forced on very input file (#74) * eof() for mapfiles was true one byte too soon (#76) * out of range \lefthyphenmin and \righthyphenmin settings now actually disable hyphenation (#90) * tex.unset_attribute() looked too far ahead when a to-be-unset attribute id not only did not exist in the node, but was also higher than the highest set attribute on the node. (#65) * the parameters attr and page_name of read_image() were swapped (this broke \pdfimage with attributes) * tex filenames with spaces in them on the command line are now allowed again (#30) * sometimes pfb fonts were included multiple times without valid reason (#29) * some parts of the pdftex 1.40.9 PNG transparancy hack were still present and caused transparant png handling to fail * \localinterlinepenalty and \localbrokenpenalty were broken * special case catcode tables are now handled better (#23) * the handling of missing .notdef charstrings in old pfb fonts is fixed (#27) The archives (source and binaries) can be downloaded from supelec, as usual: http://foundry.supelec.fr/projects/luatex/ Bugs and feature requests can be added to the issue tracker at http://tracker.luatex.org Have fun, Taco

BIG news! Thank you, Taco (and friends) ^_^ especially for integrating the synctex support, now I am happy editing with Jonathan's TeXworks editor. btw, what's cooking for 0.40.0? math support or page building?

Problem with complex discretionaries in \hyphenation
by Jonathan Sauer 30 Sep '08

30 Sep '08

Hello, the following PlainTeX file demonstrates my problem: %&luatex \hyphenation{De{k-}{k}{ck}en-licht} \showhyphens{Deckenlicht} % A \hyphenation{Dec-ken-licht} \showhyphens{Deckenlicht} % B \hyphenation{Schne{k-}{k}{ck}en-haus-bau-mei-ster} \showhyphens{Schneckenhausbaumeister} % C \bye This results in: This is LuaTeX, Version snapshot-0.29.1-2008092618 (Web2C 7.5.7) (HyphenationProblem.tex Underfull \hbox (badness 10000) in paragraph at lines 21--21 [][] \tenrm Dek-ke-nlicht Underfull \hbox (badness 10000) in paragraph at lines 25--25 [][] \tenrm Dec-ken-licht Underfull \hbox (badness 10000) in paragraph at lines 30--30 [][] \tenrm Schnek-ke-nhau-sba-ume-ister ) (see the transcript file for additional information) No pages of output. Transcript written on HyphenationProblem.log. B is correct, but A (should be `Dek-ken-licht' instead of `Dek-ke-nlicht' and C (should be `Schnek-ken-haus-bau-mei-ster' instead of `Schnek-ke-nhau-sba-ume-ister') are not: All hyphenation points after the complex discretionary seem to be shifted one character to the left. I'm using the trunk as of friday. What am I doing wrong? Thanks, Jonathan
