DESCRIPTION¶
This package provides the frontend of a compiler of
magic(5) files into
recognizers based on the
fileutil::magic::rt recognizer runtime
package. 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
directories and compiles all the files, and the files in all the
directories 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 generated
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.
