Unable to generate luatex formats

Unable to generate luatex formats

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!

The environment.luafilechunk is defined in luat-env.lua, that should
have been loaded at this point ( a bit earlier in luat-env.tex ).

I think either

   /usr/local/texlive/texmf-local/tex/context/base/luat-env.tex

is not the one from the latest context distribution, or an extra
luatools --generate command is needed.

You can check the \contextversion by looking at

   /usr/local/texlive/texmf-local/tex/context/base/context.tex

around line 45, it should say

  \edef\contextversion{2008.04.11 14:48}


There can be some more esoteric causes,  but these are the two most
likely ones.

Best wishes,
Taco

Hey, also exactly the same problem I posted yesterday in "updating
minimals"!

You're not alone!

in previou sversions the env was loaded runtime (this behaviour 
originated in the stepwise development of embedding bytecodes in the 
format, in the beginning all chunks were loaded at runtime); i managed 
to get rid of that; in addition to taco's suggestions ... so it could be 
that old code and new code is mixed.

Hi, I am getting a similar error on debian unstable.

Following the instructions in the debian README.MarkIV when I get to:

  luatools --ini --compile --verbose cont-en

I get the error

  ! LuaTeX error [string "luas[0]"]:1: attempt to call field 'luafilechunk' (a nil value).

(full listing at end of mail).

I have not run the ctxtools --update since I m not sure if is
appropriate for debian...

Any ideas?

Both of you, can you check that

   luatools luat-env.lua

finds the file? If not, try running luatools --generate

ctxtools --update does several things:
a) download cont-tmf.zip
b) extract to texmf-local
c) generate formats

a) is safe, b) and c) might put thing to weird places (different
distros have different conventions). A rather safe thing to do is to
unzip cont-tmf.zip to a location that you trust to be OK. You can
unzip it to either
    /usr/local/share/texmf/
or to .texlive (check if one exists) and then regenerate formats in
the "debian way". If you put files to /usr/local/share/texmf/, the
next, the next update (does it ever happen?) will update those files
(uninstall might possibly leave some files there if they were not
present in your previous installation). If you put context to your
local tree, you only need to make sure not to forget about it. If you
upgrade context with debian later, the tree in your home will have
precedence.

But in general there should be no problem updating some files on
debian. If you don't trust ctxtools, just do it manually.

You can also run rsync from minimals.contextgarden.net to update
context files instead of downloading and extracting the zip from
pragma.

I just get a blank line printed. And I get the same if I feed it the name
of a random, non-existent file. Which is not encouraging...

This produces:

  LuaTools | skipping /texmf-local/web2c/texmf.cnf
  LuaTools | skipping /texmf/web2c/texmf.cnf
  LuaTools | 
  LuaTools | runtime: 0.003 seconds

I then still get the same error unfortunately :(

aha, so how about setting the env variables TEXMFCNF and TEXMF

aha indeed!

Setting TEXMF was missing from the instructions in debian... Or perhaps I
messed up my configuration in the past.

  luatools --ini --compile cont-en

works now.

I will start playing with it.

A quick try of the example snippet did not work (see dump at end of
message) but I will look into it more and try Mojcas advice re
ctxtools --update.

Thanks.

Re: Unable to generate luatex formats

[Hans van der Meer]

Same thing here. "luatools luat-env.lua" gives an empty line. After  
"luatools --generate" again the same.
And I have TEXMFCNF and TEXMF defined in .bashrc
TEXMFCNF="/usr/local/texlive/2007/texmf/web2c"
TEXMF="{/Users/hans/TeX/texmf-private,/usr/local/texlive/texmf- 
context,/usr/local/texlive/texmf-local,/usr/local/texlive/2007/texmf,/ 
usr/local/texlive/2007/texmf-config,/usr/local/texlive/2007/texmf- 
dist,/usr/local/texlive/2007/texmf-doc,/usr/local/texlive/2007/texmf- 
var}"

So there must be something else amiis.

ctxtools --update won't help you as you have some missing fonts (msam7.tfm).
http://packages.debian.org/etch/all/texlive-base/filelist claims that
the file should be present in texlive-base in Debian, so it's a bit
confusing.

Hi Mojca,

There is a file here:

  /usr/share/texmf-texlive/fonts/tfm/public/ams/msam7.tfm

But I don't know what else is needed.

I would say that the installation might be slightly broken, even if
only a few variables are missing. How exactly did you install LuaTeX
and latest ConTeXt?

>  Setting TEXMF was missing from the instructions in debian...

This should not happen, but once you answer the question about how you
have installed it, it might become clearer.

Some time ago there was some problem on debian since Hans's lua
scripts were unable to parse TEXMFCNF (texmf.cnf) files properly, but
this might have been resolved in the meantime.

Mojca,

I followed the instructions here, where applicable for debian sid:

<http://wiki.contextgarden.net/Debian_installation>

Then the instruction in the README.MarkIV that appeared in the pckage
documentation directory (appended to end of post).

However I have been using context for years, and may well have messed
something up! It seems to work OK with my "normal" documents. Except I
notice \usemodule[gnuplot] does not work.

============================================================

README.luatex
=============

Mark IV is the name of the LuaTeX-aware part of ConTeXt; that is, when you
use ConTeXt over the LuaTeX engine instead of PDFTeX or XeTeX. You run it
with texexec --lua.

Currently the integration of Mark IV into Debian is not completely done,
especially because the details are currently worked out (see the dev-context
mailing list).

If you want to start using Mark IV the following the following few points
should get you started:

1) Right versions:
    luatex >= 0.20.2
    context >= 2007.12.20

2) environment variables and luatex-cache
   Mark IV ships its own implementation of file searching and doesn't
   use the ls-R databases, but luatex-cache. You have to tell luatools
   where to find texmf.cnf, and then generate the cache:
   	export TEXMFCNF=/usr/share/texmf/web2c
	luatools --generate --verbose
   This will generate the luatex-cache in $HOME. If you want to put it
   somewhere else set (and export) the TEXMFCACHE variable (like
   export TEXMFCACHE=/tmp)

3) Generate a Mark IV format
   This is not integrated into the usual format building process, and 
   probably will need some time to be worked out completely as the 
   current fmtutil cannot cope with Mark IV formats. Call
   	luatools --ini --compile cont-en

4) Now you can try some simple document like (thanks to Arthur Reutenauer)
	\starttext

	\ctxlua{a = 1.5 ; b = 1.8 ; c = a*b ; tex.print(c) ;}
	or the equivalent:
	\startlua
	a = 1.5
	b = 1.8
	c = a*b
	tex.print(c)
	\stoplua

	You can also do more elaborate calculations with the lua math library:
	\ctxlua{tex.print("$\string\\sqrt{2} = " .. math.sqrt(2) .. "$")}

	\stoptext
  and run it with
  	texexec --lua filename.tex

Not true. This code used to work, it DID WORK. But now it gives an  
error:
system         : cont-sys loaded
(/Users/hans/TeX/texmf-private/tex/context/user/cont-sys.tex

I am not happy to see something so simple now being broken!!

That probably happens with just any file, right? Try to comment out
\forceMPTEXgraphictrue from
    /Users/hans/TeX/texmf-private/tex/context/user/cont-sys.tex

This is why ConTeXt MK IV is still called experimental, and you should
be aware of that when using it.

the upcoming release will

\let\forceMPTEXgraphictrue\relax

actually nothin gis really broken, it's just that supp-mps is no longer

For the record, this now appears to be fixed thanks to help of Norbert
and Mojca.

Hi Norbert,

I updated debian and sure enough there is a new luatex - was that you?

But this in itself did not fix things immediately.

I then looked at /usr/local/share/texmf and now realise that this
installation is not the debian one, it must have come from something
off the website as you suspect.

I got rid of it with a rm -rf.

I then realised that my manual setting of TEXMF (suggested by Hans)
was wrong - I was only setting it to /usr/local/share/texmf which
omits most of tex. I think then when I generated the lua cache that is
why it could not find the fonts.

So I unset TEXMF and followed your README instructions again - and it
is working now it seems!

(I don't know whether the luatex update was needed or not).

Anyway thank you very much for your help, and Mojca too.

I have got this working now too. The problems were:

  - the syntax seems to have changed since I originally used it. Used
    to be \startGNUPLOTgraphic now needs to be \startGNUPLOTscript

  - I missed the bit on the wiki about enabling write18

  - I was misled by some examples (in the source code) into thinking
    that parameters go in curly brackets, but this does not work for
    me (and fails silently).

So in the source code you have

  \startGNUPLOTscript{sin}
      plot sin(x)
  \stopGNUPLOTscript
  \useGNUPLOTgraphic{sin}

but I needed


  \startGNUPLOTscript[sin]
      plot sin(x)
  \stopGNUPLOTscript
  \useGNUPLOTgraphic[sin]

to make it work.

I'm sorry about that. Yes, the syntax change is my fault, but it won't
happen again. If I wanted to support
   \useGNUPLOTgraphic[sin][1,3][width=.7\textwidth]
and alike, the curly braces didn't fit in so nicely.

The module has initially been part of ConTeXt (Hans has written most
of it at the beginning), but it was easier to develop it as a module
once I started writing metapost code for the dedicated terminal etc.

I have removed the faulty examples a few days ago (just didn't upload
the new version yet). I was trying to write code in such a way that
curly braces would work as well for backward compatibility, but failed
to do so (the code is there, but only half of it works). However, all
of these changes have happened rather early in the process and won't
happen again.

Moreover, it would be nice to get the TikZ terminal working with
ConTeXt (I need to find some time for it, and then finally convince
the gnuplot developers to include it into the binary).

Just "pulling" later won't help you (most probably?).

I'm now updating LuaTeX for windows to the development version if that
would change anything (but I doubt it). You can try again in several
minutes. I'm actually sitting near a windows machine, so I can also
try it myself now.

Yes it's fine, the square brackets are better.

I really like gnuplot and the gnuplot module. It is great to be able
to include the data inline with the document. And it would be nice to
see it part of the distribution. I am using a stock debian gnuplot, so
I don't know the implications of the context and TikZ terminals. Does
it mean I would not end up with so many  *-gnuplot-* files? :)

The banners (first line of luatex --version, texlua --version,

snapshot-0.25.2

No major difference. But it would (should, at least) be compatible
with all the three: LaTeX/plain/ConTeXt.

When I have developed the terminal with enormous Hans's and Taco's
help, I have asked him to implement some functionality to delete the
files with ctxtools --purge. He has implemented some functionality
(\registertempfile or something - need to check), but it deletes the
files automatically at the end of run, so one either needs to:
- delete the files
- leave the files
- no option to delete files with ctxtools
The problem with deleting the files immediately is that if you make a
trivial mistake in the gnuplot script, gnuplot won't create any
output, and it's rather difficult to spot the error in the long bunch
of ConTeXt messages. You just get no graphic, any you wonder why.

Do you have any suggestions about how to reduce the number of files in
some sensible way?

Mojca

I don't use gnuplot, but it's the same problem with lilypond - lots  
of files cluttering my project directory.

It would be a good solution if we could write all those temp files to  
a configurable directory (that one can delete or not).
The problem is probably that our client app (gnuplot, lilypond) or at  
least ConTeXt's "has changed" testing depends on that files.
If you find a solution for gnuplot I'd like to copy it for lilypond.

The ideal would be an option when processing the source file, to turn
off file deletion. Like

texexec document.tex --keep-temporaries

So by default the source directory would be kept clean, but when
"debugging" the intermediate files would be available.

Or perhaps some option passed to \startGNUPLOTscript (or
\useGNUPLOTgraphic) if that is possible?

 \startGNUPLOTscript[example][keeptemporaryfile=yes]

That might be better otherwise debugging a big document could result
it hundreds of files.

Another possibility would be to put the files in /tmp.

A configurable directory would indeed be the perfect solution (also
for other temp files).

Which is not always desirable. If I have
plot 'data.dat'
and change data, then the graph won't be recompiled.

This sounds fine (having a --debug-like option), but one more question
- what about caching existing results? (If all files are deleted, then
it's not possible to ask for --ifchanged, so gnuplot needs to be run
each time.)

That's not too practical.

Actually the configurable temp dir would be OK too.

  texexec document.tex --tempdir=./temporaries

Regarding cacheing, this would be nice but I don't know if it can be
done. I think you still need to run gnuplot in case the data has
changed.

Unable to generate luatex formats

[Michael Green]

[A] My experience is similar to Hans van der Meer's (quoted below).

luatools --generate does what I think it's supposed to.

luatools luat-env.lua returns a blank line.

[B] I followed Thomas Schmitz's instructions and used the  
source .luatex method, for what it's worth.

http://archive.contextgarden.net/message/ 
20071002.175335.21873a03.en.html

.luatex contains:

export TEXMFCACHE="/tmp"
export TEXMFCNF="/usr/local/texlive/2007/texmf/web2c"
export TEXMF="{/Users/michaelgreen/.texlive2007/texmf-config,/Users/ 
michaelgreen/.texlive2007/texmf-var,/Users/michaelgreen/Library/ 
texmf,/usr/local/texlive/2007/texmf-config,!!/usr/local/texlive/2007/ 
texmf-var,/usr/local/texlive/2007/texmf,/usr/local/texlive/2007/../ 
texmf-local,!!/usr/local/texlive/2007/texmf-dist}"
export LUAINPUTS="{/usr/local/texlive/texmf-local/tex/context/base,/ 
usr/local/texlive/2007/texmf-dist/scripts/context/lua,/usr/local/ 
texlive/texmf-local/scripts/context/lua}"

[C] Is there a chance that this is a permissions issue? I had to make  
luatools.lua executable by hand.

None of the other files in that directory are executable, where  
'that' directory is:

  /usr/local/texlive/texmf-local/scripts/context/lua

Re: Unable to generate luatex formats

[Michael Green]

The two files Taco pointed to *appear* to be OK (though I'm too  
inexperienced to say with certainty). That leaves something esoteric  
or a tossed salad of old and new code.

Since this is mainly a matter of learning and curiosity for me, I'll  
wait and see how things develop for a bit.

Thanks for your help!
