NAME
HTML::Mason::Tools - Function library used internally in Mason
DESCRIPTION
This module contains exportable functions that are intended to be used by other Mason modules.
The documentation here is primarily intended to be used by Mason core developers.
Others who choose to use these functions do so at their own risk, as they may change from release to release. You have been warned.
FUNCTIONS
- read_file
-
This function takes a file name and an optional argument indicating whether or not to open the final in binary mode. It will return the entire contents of the file as a scalar.
- paths_eq
-
Given to paths, this function indicates whether they represent the same location on the filesystem. It does not account for symlinks.
- compress_path
-
This turns a component path into a filesystem-friendly path by escaping potentially meaningful characters.
- absolute_comp_path
-
Given a component path and a directory path, this function returns the absolute component path, prepending the directory path if needed.
- mason_canonpath
-
This function cleans up a component path and returns its canonical version. It is largely the same as File::Spec::Unix::canonpath, with a few additional cleanups.
- pkg_installed
-
Given a module name, this function returns true or false to indicate whether or not a corresponding .pm file exists.
- pkg_loaded
-
Given a module name, this function returns true or false to indicate whether or not the module has been loaded into memory.
- load_pkg
-
Given a module name, this function attempts to load it. It takes an additional boolean parameter indicating whether or not to throw an exception if the module cannot be found. By default, if the module cannot be found, this function simply returns false.
All errors generate exceptions no matter what.
If the module is loaded successfully, this function returns true.
- taint_is_on
-
Returns a boolean value indicating whether taint mode is on or not.
- coerce_to_array
-
Given a scalar, which may be a reference, this function attempts to return an array. It throws an HTML::Mason::Exception::Params exception if this can't be done.
This function is called from the generated component code as part of a component's argument handling.
- coerce_to_hash
-
Given a scalar, which may be a reference, this function attempts to return a hash. It throws an HTML::Mason::Exception::Params exception if this can't be done.
This function is called from the generated component code as part of a component's argument handling.
- checksum
-
Computes a simple checksum of a string. Used for Compiler::object_id.
