Lua in LuaLaTeX is diferent??
Hi, I did a Lua application for ConTeXt, and now I wanted to adapt it to work even LuaLaTeX. On what needs to be careful? Compiling by LuaLaTeX specific messages appear as if the Lua in LuaLaTeX didnt know some Lua commands (i.e. split, find .... ). On what needs to be careful generaly when programming applications for LuaLaTeX? Thanx Jaroslav

You need the lualibs package, which imports some of the extended lua librarires from ConTeXt, since string.split() is not a standad lua function. Regards, Khaled

You probably mean something ... UserCSVSeparator = ';' UserCSVLeftDelimiter = '' UserCSVRightDelimiter = '' function ParseCSVdata(string2parse, separator, leftdelimiter, rightdelimiter) leftdelimiter = leftdelimiter or Ld or UserCSVLeftDelimiter or "" rightdelimiter = rightdelimiter or Rd or UserCSVRightDelimiter or "" if leftdelimiter ~= '' and rightdelimiter ~= '' then local result = { } local pattern = string.esc(leftdelimiter) .. "(.-)" .. string.esc(rightdelimiter) for s in string.gmatch(string2parse,pattern) do table.insert(result,s) end return result else return string.split(string2parse,separator or Sep or UserCSVSeparator or ";") end end but anyhow, this might (name) clash at some point i guess, for instance because of using globals like Ld In order to be more or less compatible with the context module and third party code setup, in context you need to do: thirddata = thirddata or { } thirddata.cvs = { separator = ';', leftdelimiter = '', rightdelimiter = '', } function thirddata.cvs.parse(string2parse,separator,leftdelimiter,rightdelimiter) leftdelimiter = leftdelimiter or thirddata.leftdelimiter or "" rightdelimiter = rightdelimiter or thirddata.rightdelimiter or "" if leftdelimiter ~= "" and rightdelimiter ~= "" then local result = { } local pattern = string.esc(leftdelimiter) ..

In context there is quite some lua code that can be used by users for their applications. The l-*.lua files can considered to be more general libraries and most ofthat is unlikely to change (extended for sure). At some point I will make a manual for that. Of course you can always load such modules using 'require'. Using other context lua code outside context is more tricky as it also assumes the system to be designed in a certain way. I hope to have much if that stable within the next few years. As long as one does not mess with the namespaces not much harm can be done. I'm not following lualatex dev but i know that it uses some of the font code. The reason that this code can be shared is that it's sort of isolated and specific functionality needed is wrapped up in *-dum.lua modules. Probbably some stripping down will happen to prevent clashes etc. Here the reference is luatex-plain.tex (and luatex-fonts.tex) in the context distribution. Also, the reverse is also tricky: lualatex speicific code is unlikely to work in context. BTW, Sharing macro code between context and latex is non trivial either as both are different systems and developed completely independent.

Hi, Hans Thanks a lot for advice and inspiration. With your contribution of my applications running under LuaPlain well below LuaLaTeX :-). Application process CSV tables and allows you to easily print the data in CSV tables (mailmerges, cards, etc). Now I do not know whether somebody else will be interested in my application. ConTeXt uses the few people around me. Therefore, I try to modify it to LuaTeXu and LuaPlain. I think I'm just a lousy programmer, and therefore do not anticipate that the application could become a larger library, you could use others. Thanks again for your time and valuable advice Have a nice day Jaroslav Dne 6.6.2010 13:13, Hans Hagen napsal(a):
