bug with \ifcsname, ttf font spacing problems, and catcode initialisation for utf8 beyond ascii
by Olivier Binda 14 Sep '07

14 Sep '07

Hello... I have been testing luatex some more and I have made the following discoveries : A) The \ifcsname macro doesn't behave as it should when you use non ascii char between \ifcsname and \endcsname, as you can see if you try to luatex this minimal file : \expandafter\def\csname A人\endcsname{success}% 1) % succeeds \csname A人\endcsname \par 2) % fails...this is a \ifcsname bug \ifcsname A人\endcsname it should write this but it doesn't \else it writes this and it shouldn't% it goes this way, sigh.... \fi \bye B) non-ascii utf8 char don't seem to have their catcodes initialized to "letter" (catcode 11). Is this normal ? Is it a bug ? a feature ? XeTeX initializes all non ascii char as letters. This is quite usefull (and quite logical too). Shouldn't it be the same in luatex, at least for the sake of compatibility ? C) I have tried using a ttf font in luatex but It was only half a success : I read the luatex manual but was really at a loss to guess how to code a function in lua to load the .ttf font, so I did a lot of googling and I finally found this luatex-wiki (started by Yannis Haralambous) : http://luatex.bluwiki.com/ I tried Yannis Haralambous's code sample to load a ttf font : \pdfoutput1 \directlua0{ callback.register('define_font', function(name, size) filename=kpse.find_file(name,"truetype fonts") if (filename) then if (size < 0) then size = (- 655.36) * size end ttffont = fontforge.to_table(fontforge.open(filename)) if ttffont then f = { } f.name = ttffont.fontname f.fullname = ttffont.names[1].names.fullname f.parameters = { } f.designsize = size f.size = size direction = 0 f.parameters.slant = 0 f.parameters.space = size * 0.25 f.parameters.space_stretch = 0.3 * size f.parameters.space_shrink = 0.1 * size f.parameters.x_height = 0.4 * size f.parameters.quad = 1.0 * size f.parameters.extra_space = 0 f.characters = { } mag = size / 2048 names_of_char = { } for char, glyph in pairs(ttffont.map.map) do names_of_char[ttffont.glyphs[glyph].name] = ttffont.map.backmap[glyph] end names_of_glyph = { } for char, glyph in pairs(ttffont.map.map) do names_of_glyph[ttffont.glyphs[glyph].name] = glyph end for char, glyph in pairs(ttffont.map.map) do glyph_table = ttffont.glyphs[glyph] f.characters[char] = { index = glyph, width = glyph_table.width * mag, name = glyph_table.name, } if glyph_table.kerns then local kerns = { } for _, kern in pairs(glyph_table.kerns) do kerns[names_of_char[kern.char]] = kern.off * mag end f.characters[char].kerns = kerns end end f.filename = filename f.type = 'real' f.format = 'truetype' f.embedding = "full" f.cidinfo = { registry = "Adobe", ordering = "Identity", supplement = 0, version = 1 } end else f = font.read_tfm(name, size) end return f end ) } \font\myfont=skullz.ttf at 8pt \myfont abcdefABCDEF %%% it prints but the all the chars are stacked upon another (they must have near 0pt width). Luatex managed to load the ttf font (it stopped whining about not finding metrics) yet, when I write something with this font, the spacing is all wrong (all the letter stack in one place). So I guess the metrics that luatex managed to produce is wrong (the char seem to have near 0 width). What could be wrong ? D) Please, could you put more code snipets in the luatex manual (this piece of code from yannis would be a good candidate) ? I welcome Yannis' decision to build a luatex wiki and it would be even nicer if someone knowledgeable wrote a little luatex macro library to do (the right way) basic things like : loading utf/opentype fonts.... To help beginners jump on the luatex bandwagon.... Best regards, Olivier Binda ps : now that the \atop bug is resolved...my 150+ page maths course does compile with luatex (yeepee). My japanese dictionnary does compile too but it doesn't produce the expected result because of the \ifcsname behavior ^_^

(fwd) Bug#441836: fails to install
by Hilmar Preusse 13 Sep '07

13 Sep '07

Dear luatex maintainers, down here in the Debian Bug Tracking system we got a report telling that luatex is not able to build its own format file on power pc. The version specified is 0.11.0, which is in reality the 20070820 snapshot (as far as I can see). Please note that the Debian packet links dynamically with the following libs in Debian instead of using the provided libraries: zlib, libpng, libjpg. Please advise. Regards, Hilmar -- sigmentation fault

\pdfmapfile and texconfig.trace_file_names
by James Quirk 11 Sep '07

11 Sep '07

Hi, I couldn't find a list of known bugs in luatex at http://foundry.supelec.fr/projects/luatexi, so apologies if the following has already been reported. \pdfmapfile does not obey the flag texconfig.trace_file_names. For example, create a stub file foo.map then run: \directlua 0 { texconfig.trace_file_names = false } \pdfmapfile {+foo.map} \pdfmapfile {+foo.map} \pdfmapfile {+foo.map} \bye James Quirk

\pdfmapfile and texconfig.trace_file_names
by James Quirk 11 Sep '07

I've traced the problem to the routine fm_read_info in the file src/texk/web2c/luatexdir/font/mapfile.c. The tracefilenames flag is only honoured when the read_map_file callback is active. This would seem to be inconsistent with the treatment of \input where the flag is honoured irrespective of the find/open_read_file callbacks. James
