tex.currentgrouplevel
by Jonathan Sauer 21 Sep '08

21 Sep '08

Hello, given is the following PlainTeX file: %&luatex % \message{\the\currentgrouplevel} \directlua0{texio.write_nl(tex.currentgrouplevel)} \bye This results in: This is LuaTeX, Version snapshot-0.29.0-2008072919 (Web2C 7.5.7) (currentgrouplevel.tex ! You can't use `\currentgrouplevel' as tex library index. l.3 ...lua0{texio.write_nl(tex.currentgrouplevel)} ? Looking into section 4.1.1 of the manual, currentgrouplevel is not in the list of tex's integer parameters -- unfortunately. It would be a quite useful addition in order to create `grouped variables' in Lua (variables whose previous value is restored at the end of a TeX group): -- Assume there are TeX two count registers allocated, `stackIndex' -- and `groupIndex' tex.count.stackIndex = 0 tex.count.groupLevel = -1 -- The `grouped variable' stack local stack = { } -- Sets a `grouped variable' function set(name, value) if tex.currentgrouplevel > tex.count.grouplevel then -- New group opened since the last time. Create a new stack -- element tex.count.stackIndex = tex.count.stackIndex + 1 stack[tex.count.stackIndex] = { } tex.count.groupLevel = tex.currentgrouplevel -- TODO: Optional: Clear the stack above the new element to -- release old values end -- Add the value stack[tex.count.stackIndex][name] = value end -- Gets a `grouped variable' function get(name) -- Look through the stack, top to bottom for i = tex.count.stackIndex, 1, -1 do if stack[i][name] then return stack[i][name] end end -- Value not found return nil end Jonathan

It might be the same problem as this one: =================== >> ! Font \T1/cmr/m/n/10=ecrm1000 at 10pt not loadable: metric data >> not found or bad. =================== It looks as it is the same problem. I have run tftopl + pltotf on the fonts, but it does not work. I get the problem even with cmr: =================== C:\Archivos de programa\TeXLive\texmf\tex\eplainJA>luatex -ini minimum_font.tex This is LuaTeX, Version snapshot-0.25.4-2008071819 (Web2C 7.5.7) (INITEX) (minimum_font.tex ! Font \tenrm=cmr10 not loadable: metric data not found or bad. =================== > There is a luatex fix in svn I have not yet tried. I'll first have to learn to work with svn. Hope next week I'll have some time. Chao Javier A.

Looking for OFM files (why?)
by Javier Múgica 04 Sep '08

04 Sep '08

Helo: I have done my best before posting the question to the list. I'm trying to generate a format but I get an error with LuaTeX. With pdfTeX there is no problem. I attach a minimum format file, plus the output with -kpdebug=3 for both LuaTeX and pdftex, as well as the last lines of -kpdebug=-1 with LuaTeX. Note that in this later case luaTeX finds the .tfm file, but keeps looking for an ofm one. I don't have OFMFONTS defined in my texmf.cnf. I removed it since I don't have any such file. I thought about the -kpdebug option because I vagely remembered that it existed, and found it with pdftex --help. However this and other options are not described with luatex --help. Ok, I agree that now this is not very important, but some time it shall be done, and it seems so easy (copy paste the text from pdftex?) that it could be done now. --Javier A.

problem with os.spawn+os.execute on win32
by Manuel Pégourié-Gonnard 02 Sep '08

02 Sep '08

Hi Taco, hi Hans, hi everyone, With LuaTeX 0.25.4 from the TeX Live distribution, I get a strange behaviour when, in a texlua script, I call another texlua script which in turn calls a program, depending on the sequence os.spawn and/or os.execute I use. Example, assuming acrord32 is in the PATH and presentation.pdf exists: % wrapper.tlu kpse.set_program_name("texlua") os.spawn('texlua d:/mpg/program.tlu') -- or... -- os.execute('texlua d:/mpg/program.tlu) % program.tlu os.execute ('acrord32 "d:\\mpg\\presentation.pdf"') -- or... -- os.spawn ('acrord32 "d:\\mpg\\presentation.pdf"') Now if I run 'texlua wrapper.tlu' from a command line, when Adobe Reader 9 starts, it immediatly crashes showing an error box "internal error". The problem disappears under one of the following conditions: 1. Change os.spawn to os.execute in wrapper.tlu and/or os.execute to os.spawn in program.tlu. 2. Do the same on linux (with trivial path adaptations). 3. Use something else than Adobe Reader (or Adobe Acrobat) 8 or 9. 4. Comment the call to kpse.set_program_name(). I tend to believe that 3 and 4 a rather anecdotic, and though in theory the problem could come from kpse or AR, it may actually be more related to os.spawn. A quick look at loslibext.c let me think that os.spawn is indeed rather tricky on windows (and at least more than on *nix). So, what do you think? Is it a bug or I am doing something wrong? Thanks, Manuel.
