NAME¶
fileutil::magic::cgen - Generator core for compiler of
magic(5) files
SYNOPSIS¶
package require
Tcl 8.4
package require
fileutil::magic::cgen ?1.0?
package require
fileutil::magic::rt ?1.0?
package require
struct::tree
package require

::fileutil::magic::cgen::2tree script
::fileutil::magic::cgen::treedump tree
::fileutil::magic::cgen::treegen tree node
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.
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
::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.
