Collected notes
by Jonathan Sauer 25 Sep '07

25 Sep '07

Hello, some notes I collected while testing LuaTeX beta 0.11.2: - It should be noted in the manual that \luaescapestring completely expands its parameter. - When setting a \toks register in Lua using tex.toks['foo'] = 'bar' et.al., what catcodetable is used? From looking inside luatex.web, I would guess that, since str_toks is used, all characters get catcode 12, except for spaces, which get catcode 10. A quick test confirms this. In case this is neither a bug nor a temporary hack: This IMO severely limits the usefulness of the tex.toks table, since the toks registers written in Lua later have to be re-scanned in TeX. IMO, tex.settoks should be passed an optional parameter to set the catcode table to use. When using array addressing, the current catcode table should be used (just like tex.print/tex.sprint). - What exactly is meant by "Lua strings are converted to token lists using \the\toks style expansion" (pg. 23)?

Lua states and \dump
by Jonathan Sauer 25 Sep '07

25 Sep '07

Hello, (yes, it's me again ;-) Yesterday I noticed that when \dump-ing a format file, the Lua states are not dumped as well, discarding all initializations made while creating the format. This is not a problem, since the initializations can be put into \everyjob, and of course from a technical angle it would be really difficult to dump a Lua state to the format file (requiring access to the internals of the Lua VM which can change at any time), but IMO this should be noted in the manual.

tex.print and \inputlineno
by Jonathan Sauer 25 Sep '07

25 Sep '07

Hello, while testing, I stumbled on a (then) strange phenomenon concerning line numbers in tex.print. It seems that \inputlineno is not equal to the number of the line of the tex.print statement (or the macro expanding to it), but of the virtual file tex.print uses internally. Example (PlainTeX): -------------------------------------------------------------------- % Output is `1' instead of `3': \directlua0{\unexpanded{tex.print('\\message{\\the\\inputlineno}')}} % Output is `1' instead of `6': \scantokens{\message{\the\inputlineno}} \bye -------------------------------------------------------------------- Results in: This is luaTeX, Version 3.141592-beta-0.11.2-2007091918 (Web2C 7.5.6) (format=luatex 2007.9.20) 24 SEP 2007 15:25 **LineNumberTest.tex (LineNumberTest.tex 1 1 ) No pages of output. As you can see, eTeX's \scantokens exhibits the same behaviour (most likely because it also uses a virtual file). But I think that tex.print will be used more often than \scantokens, since it is the only way to pass arbitrary tokens from Lua to TeX. This means that when TeX executes these tokens, log messages will use not the line number of the TeX macro that expanded to the Lua code that created new TeX tokens, but the "virtual line number" (as seen in the example above). These log messages (and most likely \errmessage-s as well) are not very useful. Jonathan

Bug with "\atop"
by Olivier Binda 23 Sep '07

23 Sep '07

Hello.... Luatex crashes when trying to compile the following minimal file (100% reproductible bug on my config) : ${1\atop 2}$\end I'm using W32TeX and the luatex version that comes bundled with it. Keep up the good work, Olivier
