Unable to generate luatex formats

I'm getting the following error when running this command: luatools -- ini --verbose --compile cont-en LuaTools | running command: luatex --ini --lua="cont-en.luc" "/usr/ local/texlive/2007/texmf-dist/tex/context/base/cont-en.tex" \\dump This is LuaTeX, Version snapshot-0.25.2-2008041101 (Web2C 7.5.6) (INITEX) (/usr/local/texlive/2007/texmf-dist/tex/context/base/cont-en.tex (/usr/local/texlive/2007/../texmf-local/tex/context/base/context.tex (/usr/local/texlive/2007/../texmf-local/tex/context/base/syst-pln.tex) (/usr/local/texlive/2007/../texmf-local/tex/context/base/syst-prm.tex) (/usr/local/texlive/2007/../texmf-local/tex/context/base/luat-env.tex !

I see that it is similar to an error that ZS had. http://www.ntg.nl/pipermail/ntg-context/2008/030012.html But while ZS's problem was solved by updating, I'm installing for the first time with the newest versions. What might be amiss? Thanks! mjg

Pb with ConTeXt ver: 2008.04.16 17:34 and mkiv
by Otared Kavian 17 Apr '08

Hi Hans and Taco, I would like to report a problem with the latest release: I just updated my ConTeXt installation and got the following error message: […] This is LuaTeX, Version snapshot-0.25.2-2008041100 (Web2C 7.5.6) (INITEX) (/usr/local/gwTeX/texmf.texlive/tex/context/base/cont-en.tex (/usr/local/gwTeX/texmf.texlive/tex/context/base/context.tex (/usr/local/gwTeX/texmf.texlive/tex/context/base/syst-pln.tex) (/usr/local/gwTeX/texmf.texlive/tex/context/base/syst-prm.tex) !

My previous version of mkiv used to work fine until ConTeXt version 2008.04.16 11:45. For your information, I am running this on MacBook Pro Intel running MacOS X 10.5.2, and I follow Thomas Schmitz' indications to install LuaTeX. Best regards: OK

Adding custom key/value pairs
by Rory Molinari 17 Apr '08

17 Apr '08

Hi, I'm new to ConTeXt and decided to teach myself a bit by resetting my old thesis (originally done, many years ago, in LaTeX). As the purpose is to teach myself ConTeXt rather than just have an electronic version of the thesis I decided to try to do things the "right" way. So, in setting the title page I followed the pattern shown on Contextgarden here: http://wiki.contextgarden.net/Document_Titles. That page shows how to define a nice \placetitle command with an associated \setuptitle which allows us to define values for title, subject, and date. However, I want also to be able to define values for degree, subject, and committee (to follow the school-standard LaTeX style file I had from all those years ago). I can't work out how to do this. Simply using a variable like \c!degree (to match the \c!title I found in the example) doesn't work, as ConTeXt doesn't know about such a control sequence. I was quite puzzled for a while but then it dawned on me that the example I found on contextgarden works because the keys it uses (for key/value pairs) are ones that are already defined in the ConTeXt system: title, subject, date. My attempt fails because the system doesn't know about degree, subject, and committee. I tried defining a new variable with startvariables, but that didn't appear to help. So, my question: what do I need to do to define a new key that can be used in a key/value pair? Here's an example of what I tried: \startvariables all degree: degree \stopvariables \definesystemvariable{tp} % title page \def\setuptitlepage{\dodoubleempty\dosetuptitlepage} \def\dosetuptitlepage[#1][#2]% {\ifsecondargument \dodosetuptitlepage[#1][#2]% \else \dodosetuptitlepage[\v!content][#1]% \fi} \def\dodosetuptitlepage[#1][#2]% {\def\dododosetuptitlepage##1% {\getparameters[\??tp##1][#2]}% \processcommalist[#1]\dododosetuptitlepage} \def\placetitlepage {\startalignment[\v!middle] \doattributes{\??tp\c!degree}\c!style\c!color\@@tpcontentdegree \stopalignment} \setuptitlepage [\c!degree] [\c!style=\tfa,\c!color=] \startfrontmatter \placetitlepage \stopfrontmatter \starttext \stoptext Cheers, Rory

This has the advantage that one has not to adapt 'plain.mp'. But here too, there is no 'mpost.mem' and no 'mpost.log'. I have included a test before and after mp:finish(). Can anybody with a minimal under windows run this example? ------------------------------- \starttext % start low-level \startlua local function finder(name, mode, ftype) if mode=="w" then return name else return kpse.find_file(name,ftype) end end mp = mplib.new ( { hash_size = 100000, main_memory = 2000000, param_size = 100000, find_file = finder, ini_version = true } ) if mp then res = mp:execute("mpost") tex.print("[" .. tostring(res.status) .. "]") print(table.serialize(res)) if io.open("mpost.mem","r") then print("found") else print("nothing") end res = mp:finish() print(table.serialize(res)) if io.open("mpost.mem","r") then print("found") else print("nothing") end end \stoplua % stop low-level \stoptext ------------------------------- Gruß, Wolfgang

LuaTeX problems with \seeindex and \from
by Drazen Baic 16 Apr '08

16 Apr '08

Hi, this is my first posting to this list but I'm following it through the archives for quite a long time. First I would like to thank the list for this huge archive. By reading the documentation and searching this archive most of my questions about ConTeXt where answered. I searched for these problems but couldn't find anything. Now to my question: I was generating my documents with XeTeX until I switched to LuaTeX and MKIV a few days ago. After I changed my typescripts almost everything worked perfectly but the commands \seeindex[]{}{} and \from[]. 1) \seeindex simply doesn't seem to work. The index is generated but all \seeindex entries are missing. It works perfectly when generated with 'texexec --xtx'. Generating the document with \version[temporary] shows in the margin '> i Indexentry' and '> see Showindexentry' so it seems that both entries are ok. I set up the register with '\completeindex[interaction=text,align=yes]' Is this a bug or are \seeindex entries handled different with LuaTeX? 2) The other problem took me quite some time to find out. When I create the document with 'texexec --lua' LuaTeX it seems that everything runs fine but no document is generated. There are no error messages even with '--verbose' set - at least I couldn't see any. Finally I found out that 'luatex' crashed during 'LuaTools | running command: luatex --fmt' (see the CrashReporter log at the end of the mail). I started to leave out all components of the product and started just with the title page, then included chapter after chapter until I found out the LuaTeX crashes when I leave the command \from[] in. I defined the URL with \useURL[apache][http://httpd.apache.org/download.cgi] and am using it in the document with \from[apache]. Here are the versions I'm using. OS: Mac OS X 10.5.2 ConTeXt: 2008.04.11 00:07 LuaTeX: snapshot-0.25.2-2008041101 Many thanks in advance and regards, Drazen Baic Process: luatex [269] Path: /usr/local/context-20080411/tex/texmf-osx-ppc/bin/luatex Identifier: luatex Version: ???

mtx-update --context=beta?
by Joel C. Salomon 16 Apr '08

16 Apr '08

I'm putting together my own rsync calls based on the Minimals firstsetup.bat and Vyatcheslav's installer. Found a difference: firstsetup.bat includes the switch --context=beta in its call to mtx-update. What is the difference if it's used or no?

luatex feature question/request
by Marcin Borkowski 16 Apr '08

16 Apr '08

Hello! I was just wondering, whether something like this is possible in luatex - and if not, if it might be implemented;). I'd like to be able to transform somehow the input right *before* TeX sees it. What I mean is e.g. a transformation using regexps. Application I have in mind is as follows: in Polish, there are a few prepositions which are one-letter words; it's a bad custom to leave them hanging at the end of a line. Such an option could automatically put ties (~) instead of spaces after them - a feature sometimes requested by Polish TeX users. Yours, -- Marcin Borkowski (http://mbork.faculty.fmcs.amu.edu.pl)
