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.
-
::fileutil::magic::cgen::2tree script
-
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::treedump tree
-
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::treegen tree node
-
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.
This document, and the package it describes, will undoubtedly contain
