missing signature in the manual
by Elie Roux 07 Feb '09

07 Feb '09

Hello, In the manual one can read: This callback allows you to replace the way LuaTeX fetches lexical tokens. function() return <table> token end I think that the argument(s) of function are missing. Also about buildpage_filter: function(<string> extrainfo) end the function doesn't need to return anything? Finally the char_exists callback is not documented but is in callback.list() Thank you! -- Elie

start_run not working
by Elie Roux 07 Feb '09

07 Feb '09

I tried the following code: \directlua0{ local function simpleone() return "I'm number 1" end local function simpletwo() texio.write_nl("I'm number 1") end callback.register("start_run",simpletwo) } and got no result neither by replacing simpletwo by simpleone in the callback. Is it normal? The simpletwo function works fine with the callbacks "stop_run". -- Elie

Floating point exception
by Javier Múgica 04 Feb '09

04 Feb '09

I don't know whether this is a problem of luatex or of my Linux, but with the latest version I get this message from the operating system (because it is in Spanish) javier@javier-laptop:~$ luatex Excepción de coma flotante javier@javier-laptop:~$ i.e., "floating point exception". I do not even see the "This is Luatex... " message. --Javier A.

Strange behaviour
by Elie Roux 02 Feb '09

02 Feb '09

Hello, here is an example of some behaviours I find quite strange... It is a really short and simple example in plainTeX. It shows that if we have set \localleftbox or \localrightbox once, every line will have two more (empty) nodes. I think this behaviour is quite uncoherent, because packages (like GregorioTeX) set some \localleftbox and \localrightbox and then unsets them, so if someone wants to count the nodes of a line, this result will depend if he has a score in his document or not, even if he counts the nodes of a line that has nothing to do with a score... I think it would be better if these empty nodes were suppressed... The other behaviour I find strange is that an attribute on a node can be both 1 and -1... It's just a curiosity, as the good way to test if an attribute exists is (I think) to call node.has_attribute with only two arguments. Also, is there a way to get the value of an attribute on a node by doing something else than testing some? Thank you in advance, -- Elie

Generating the sources
by Javier Múgica 02 Feb '09

02 Feb '09

Some time ago I had a problem with the fonts when generating the format, which I posted here. New versions didn't solve it, I always get the annoying Could not load ec-lmr12.tfm. Inexistent or bad font file, or something like that. I decided to compile and debug LuateX myself. Something worth indeed if I ever plan to become a developper. It was the first time I tangled something. I saw a luatangle.web (if my memory does not betray me), so I started tangling that, but I get pascal code, and I don't have a pascal compiler. I haven't had time ever since, so I simply stopped. Is there a way of generating c-source, or will I have to wait to September or so? If there is one, even though I am a programer a step-by-step explanation will be very wellcome. Tanks, --Javier A.
