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 struct::list ::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 consump- tion, 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. BUGS, IDEAS, FEEDBACK This document, and the package it describes, will undoubtedly contain bugs and other problems. Please report such in the category fileutil :: magic of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883]. Please also report any ideas for enhancements you may have for either package and/or documentation. SEE ALSO

NAME
fileutil::magic::cfront - Generator core for compiler of magic(5) files SYNOPSIS
package require Tcl 8.4 package require fileutil::magic::cfront ?1.0? package require fileutil::magic::cgen ?1.0? package require fileutil::magic::rt ?1.0? package require struct::list package require fileutil ::fileutil::magic::cfront::compile path... ::fileutil::magic::cfront::procdef procname path... ::fileutil::magic::cfront::install path... _________________________________________________________________ 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 result- ing 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" caus- ing the creation of procedure ::fileutil::magic::/FOO::run.
