FUNCTIONS

19       read_file
20           This function takes a file name and an optional argument indicating
21           whether or not to open the final in binary mode.  It will return
22           the entire contents of the file as a scalar.
23
24       paths_eq
25           Given to paths, this function indicates whether they represent the
26           same location on the filesystem.  It does not account for symlinks.
27
28       compress_path
29           This turns a component path into a filesystem-friendly path by
30           escaping potentially meaningful characters.
31
32       absolute_comp_path
33           Given a component path and a directory path, this function returns
34           the absolute component path, prepending the directory path if
35           needed.
36
37       mason_canonpath
38           This function cleans up a component path and returns its canonical
39           version.  It is largely the same as File::Spec::Unix::canonpath,
40           with a few additional cleanups.
41
42       pkg_installed
43           Given a module name, this function returns true or false to
44           indicate whether or not a corresponding .pm file exists.
45
46       pkg_loaded
47           Given a module name, this function returns true or false to
48           indicate whether or not the module has been loaded into memory.
49
50       load_pkg
51           Given a module name, this function attempts to load it.  It takes
52           an additional boolean parameter indicating whether or not to throw
53           an exception if the module cannot be found.  By default, if the
54           module cannot be found, this function simply returns false.
55
56           All errors generate exceptions no matter what.
57
58           If the module is loaded successfully, this function returns true.
59
60       taint_is_on
61           Returns a boolean value indicating whether taint mode is on or not.
62
63       coerce_to_array
64           Given a scalar, which may be a reference, this function attempts to
65           return an array.  It throws an HTML::Mason::Exception::Params
66           exception if this can't be done.
67
68           This function is called from the generated component code as part
69           of a component's argument handling.
70
71       coerce_to_hash
72           Given a scalar, which may be a reference, this function attempts to
73           return a hash.  It throws an HTML::Mason::Exception::Params
74           exception if this can't be done.
75
76           This function is called from the generated component code as part
77           of a component's argument handling.
78
79       checksum
80           Computes a simple checksum of a string. Used for
81           Compiler::object_id.
