DESCRIPTION
This package provides the frontend of a compiler of magic(5) files into
recognizers based on the fileutil::magic::rt recognizer runtime pack-
age. For the generator backed used by this compiler see the package
fileutil::magic::cgen.
COMMANDS
::fileutil::magic::cfront::compile path...
This command takes the paths of one or more files and directo-
ries and compiles all the files, and the files in all the direc-
tories into a single recognizer for all the file types specified
in these files.
All the files have to be in the format specified by magic(5).
The result of the command is a Tcl script containing the gener-
ated recognizer.
::fileutil::magic::cfront::procdef procname path...
This command behaves like ::fileutil::magic::cfront::compile
with regard to the specified path arguments, then wraps the
resulting recognizer script into a procedure named procname,
puts code setting up the namespace of procname in front, and
returns the resulting script.
::fileutil::magic::cfront::install path...
This command uses ::fileutil::magic::cfront::procdef to compile
each of the paths into a recognizer procedure and installs the
result in the current interpreter.
The name of each new procedure is derived from the name of the
file/directory used in its creation, with file/directory "FOO"
causing the creation of procedure ::fileutil::magic::/FOO::run.
