I'm sorry it doesn't work for me either. (have TL2005 on WinXP)
I still get the message "I can't find the TeX format 'cont-en'" unless I copy it into the 'web2c' directory.

I've noticed this in context.cnf:

TEXMFMAIN     = $SELFAUTOPARENT/texmf
TEXMFLOCAL    = $SELFAUTOPARENT/texmf-local
TEXMFFONTS    = $SELFAUTOPARENT/texmf-fonts
TEXMFEXTRA    = $SELFAUTOPARENT/texmf-extra
TEXMFPROJECT  = $SELFAUTOPARENT/texmf-project
VARTEXMF      = $SELFAUTOPARENT/texmf-var
TEXMF         = {!!$TEXMFPROJECT,!!$TEXMFFONTS,!!$TEXMFLOCAL,!!$TEXMFEXTRA,!!$TEXMFMAIN}

% --- cut ---

TEXFORMATS    = .;$TEXMF/web2c/{$engine,} 

It's strange that there isn't $VARTEXMF included in the TEXMF path. I've tried to add it:

TEXMF         = {!!$TEXMFPROJECT,!!$TEXMFFONTS,!!$TEXMFLOCAL,!!$TEXMFEXTRA,!!$TEXMFMAIN,!!$VARTEXMF}

but with no result... :-(

I'm attaching the complete context.cnf file for reference.

context.cnf is not actually used by any programs. It is only
provided as a sample of how texmf.cnf could be set up.

Excellent! Could you please add it to the distribution?

Many thanks!

P.S. I'll probably have to learn at basics of Ruby... I'm familiar with Perl, PHP, shell scripts... but the Ruby code is totally cryptic for me! :-(((

  well, we can use:
  
      def validsomething(str,something)
          if str then
              list = [str].flatten.collect do |s|
                  something[s] || s # || s added
              end .compact.uniq
              if list.length>0 then
                  if str.class == String then list.first else list end
              else
                  false
              end
          else
              false
          end
      end
  
  and then you can say
  
  texexec --all --make --texformats=cont-xx
  
  given that you have cont-xx.tex

  we really need the engine path so i wonder why the format is not found; maybe an error in the cnf file (should recursively search the web2c path for formats)

OH SO!

There was only

TEXFORMATS = .;$TEXMF/web2c 

in my texmf-var/web2c/texmf.cnf

I changed it into 

TEXFORMATS = .;$TEXMF/web2c/{$engine,}

(as suggested in context.cnf) and IT WORKS!


Many thanks for the hint, Taco!

I have the same observation. The TeXLive 2005 definition is

   TEXFORMATS = .;$TEXMF/web2c/{$engine,}

but it seems to me tex binaries do not set $engine variable. If so, it 
can be locally solved (without changing binaries and supposing not using 
xetex or another engine) by

   TEXFORMATS = .;$TEXMF/web2c//

base/tex.rb comments

[Richard Gabriel]

[-- Attachment #1.1: Type: text/plain, Size: 1129 bytes --]

Hello Hans and others,

I'd have two comments to the texmf/scripts/context/ruby/base/tex.rb script.

1. I find quite impractical that the formats (cont-en, cont-nl etc.) are hardcoded in the scripts. When one wants to add a new format, then he must add it on 4 or 5 places in the script, and do it again and again everytime when upgrading ConTeXt. :-(

2. Maybe this is an OS and TeX distribution specific issue...
I use TeXLive 2005 on Windows XP.
The TeX formats are located in C:\TeXLive\texmf-var\web2c. [the "kpsewhich --show-path=fmt" command also shows this path].
When generating a format using "texmfstart texexec --make en", the generated format is placed into C:\TeXLive\texmf-var\web2c\pdfetex. Then, when trying to use the format, it is not found...

This is done on line 547 of tex.rb:

texformatpath = if getvariable('local') then '.' else Kpse.formatpath(texengine,true) end

So I've changed it to "Kpse.formatpath(texengine,false)" and everything is fine.

But I don't understand why it is set so by default and why it doesn't work for me. 
Does anybody experience the same problem?

-Richard
