In need of some catcode wizardry...
by Graham Douglas 18 Apr '10

18 Apr '10

Hi All I hope it's OK to ask this here. I've implemented a Windows version of the Directory Iterator as described in "Programming in Lua" http://www.lua.org/pil/29.1.html and can call it with code like this \directlua{ require "luadir" for fname in luadir.dir("directory") do tex.print(fname) end } (luadir is an add-in DLL) where "directory" is a path and fname is the returned filename. fname can contain special characters so naturally, I am having catcode problems since I'm not using ConTeXt which provides a lot of tools to deal with catcodes etc when running directlua. I'm using a version of plain to run this. So, would anyone have time to suggest the best way to set this up so that I can run this to resolve the catcode issues --- in the directory names and the returned file names? I know that tex.print can take a catcode table number but I'm not sure how to best set it up. An example using \catcodetable 16-bit number and how to use + save the catcode table would be very welcome. Thanks in advance Graham

Possible issue with input from external libraries (page break problem?)
by Graham Douglas 14 Apr '10

14 Apr '10

Hi Taco I have been experimenting with external C libraries by writing Lua bindings under Windows --- DLLs. I have noticed something I'd like to ask about --- to know if it is expected behavior. When these DLLs return text I'm doing a lot of tex.write(...) of the data returned from the DLL functions (for testing). What I've noticed is that when the text data from the DLL calls is output (by tex.write()) and a page break occurs in the middle of the tex.write() outputs calls, then the text is lost across the break. Here I am guessing....> It looks like if the page break machinery is called whilst the text from the DLL is being output by tex.write() then something temporarily "forgets??" that text data is still coming and so the page break is losing data --- actually it looks like the incoming tex.write() text simply carries on and falls off the page so you lose it. Perhaps the page bbreak machinery is getting out of synch with the tex.write() input. This is purely guesswork and I could easily be wrong of course. I can e-mail you (personally?) a sample PDF which is easier than trying to explain this. Is this something to be expected? A minimal code example may not be that helpful but here is one. Here I have a binding to FreeType (I call it luatype) and in this example it just dumps the glyph names reported by FreeType: \directlua { require "luatype" local result = luatype.fontname("c:/msys/1.0/trunk/build/texk/fonts/type1/lucida/LBD.PFB") tex.print(result.glyphs) %can also say you["glyphs"], as the same thing for k,v in pairs(result) do tex.print(v.." "..k) end } Here is binding to an XML library \directlua 0 { require "lxp" text = [[<note> <to>Tove</to> <from>Jani</from> <heading>Reminder <urgent> yes, very</urgent></heading> <body>Don't forget me this weekend!</body> </note>]] local x=0 callbacks = { StartElement = function (p, s) tex.print("Starting element: ".. "{bf " ..s.. "}" .. " call depth = ".. x.. "par") x=x+1 end, EndElement = function (p, s) x=x-1 tex.sprint("Finishing element: " .. "{it " ..s.. "}" .. " call depth = ".. x.. "par") end, CharacterData = function (p, s) tex.sprint("Character data (may be white space) = " .. "{itbf " ..s.. "}" .. "par") end} p=lxp.new(callbacks) } \directlua{p:parse(text)}!. \directlua{p:close()} If the tex.write() from output of either DLLs goes near a page break it "falls off the page" and gets lost. Apologies if this is not explained very well. Please let me know if you want a PDF sample. All the best Graham

defaults for tex.linebreak()?
by Patrick Gundlach 14 Apr '10

14 Apr '10

Hi (Taco), the function tex.linebreak() is mentioned in the manual, but the defaults are not. Are the ones in the tracker item #340 still valid? Could it be that the default value for linepenalty is not taken into account? That means: if you set \linepenalty=0 from TeX, tex.linebreak() behaves differently. Patrick
