DESCRIPTION
This package provides the generator backend for a compiler of magic(5)
files into recognizers based on the fileutil::magic::rt recognizer run-
time package. For the compiler frontend using this generator see the
package fileutil::magic::cfront.
COMMANDS
::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 ::fileu-
til::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 ::fileu-
til::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.
