MensagemOk.
Well, bad news, I haven't heard of a Tcl implementation of such a thing ...
I dimly remember having heard of a perl-based decoder, now that my memory is
on the right track ...
And googling for 'mork tcl' brings up your query here on this list up as the
top result.

Is it not possible to simply use the python parser, via exec or open| ?

(I am guessing that you wish to convert firefox2 databases to firefox3 and
sqlite).
Of course, if this parser is a package, not an application, then no.

Oh, I found a reference to some java code
    http://www.mhaller.de/archives/6-Mork-or-what.html
    http://www.smartwerkz.com/projects/jmork/

Who knows, maybe you can read that easier, with Java syntax nearer to C.

Ok, the site above refers to the perl code I mentioned as well, in a few
steps

  Hi

  Mork is kind of a database language specification, used in the Firefox 2
history and some of other Mozilla applications, as the Address book in
Thunderbird.
  If you want an example of it, open the Firefox 2 history.dat (Firefox 3
uses sqlite).

  I found such parser in python, but I really don't want to learn python by
now...

  Thanks

        Hi

        Would anybody know of an implementation of Mork parser in TCL?

        Thanks in advance
