tcllib                                                1.2.0                          fileutil::magic::cgen(3tcl)

Commands

::fileutil::magic::cgen::2treescript
              This  command  converts  the recognizer specified by the script into a tree and returns the object
              command of that tree as its result. It uses the package struct::tree for the tree.

              The script is in the format specified by magic(5).

       ::fileutil::magic::cgen::treedumptree
              This command takes a tree as generated by  ::fileutil::magic::cgen::2tree  and  returns  a  string
              encoding the tree for human consumption, to aid in debugging.

       ::fileutil::magic::cgen::treegentreenode
              This command takes a tree as generated by ::fileutil::magic::cgen::2tree and returns a Tcl script,
              the  recognizer  for the file types represented by the sub-tree rooted at the node.  The generated
              script  makes  extensive  use  of  the  commands  provided  by  the  recognizer  runtime   package
              fileutil::magic::rt to perform its duties.

Description

       This  package  provides  the generator backend for a compiler of magic(5) files into recognizers based on
       the fileutil::magic::rt recognizer runtime package. For the compiler frontend using  this  generator  see
       the package fileutil::magic::cfront.
