DESCRIPTION

32       This package provides the frontend of a compiler of magic(5) files into
33       recognizers based on the fileutil::magic::rt recognizer  runtime  pack‐
34       age.  For  the  generator  backed used by this compiler see the package
35       fileutil::magic::cgen.

COMMANDS

38       ::fileutil::magic::cfront::compile path...
39              This command takes the paths of one or more files  and  directo‐
40              ries and compiles all the files, and the files in all the direc‐
41              tories into a single recognizer for all the file types specified
42              in these files.
43
44              All the files have to be in the format specified by magic(5).
45
46              The  result of the command is a Tcl script containing the gener‐
47              ated recognizer.
48
49       ::fileutil::magic::cfront::procdef procname path...
50              This  command  behaves  like  ::fileutil::magic::cfront::compile
51              with  regard  to  the  specified  path arguments, then wraps the
52              resulting recognizer script into  a  procedure  named  procname,
53              puts  code  setting  up  the namespace of procname in front, and
54              returns the resulting script.
55
56       ::fileutil::magic::cfront::install path...
57              This command uses ::fileutil::magic::cfront::procdef to  compile
58              each  of  the paths into a recognizer procedure and installs the
59              result in the current interpreter.
60
61              The name of each new procedure is derived from the name  of  the
62              file/directory  used  in its creation, with file/directory "FOO"
63              causing the creation of procedure ::fileutil::magic::/FOO::run.
