Gestinanna::Util Description

Gestinanna::Util Perl module contains utility functions. Gestinanna::Util Perl module contains utility functions.SYNOPSIS use Gestinanna::Util qw(:path); my $regex = path2regex($path) my $cmp = path_cmp($path_a, $path_b); use Gestinanna::Util qw(:hash); my $new_hash = deep_merge_hash(@hashes);This module provides utility functions that have no better place to be. Sets of utility functions may be imported by specifying their tags.:pathImports: path2regex, path_cmpPATHSPaths are made up of a sub-set of the XPath language:/The slash (/) is the component separator. Alone, it describes the root of the resource heirarchy.//The double slash (//) stands in place of any number of components (zero or more). Alone, it matches any possible path that does not specify attributes or a final component. To match any component with any attributes, use //*|//*@*.@The at sign (@) is the attribute separator. A path should only have one. It separates the final component from any attribute. If no attribute follows it, it stands for the general collection of attributes for an object.|The pipe symbol (|) separates paths which together specify a union.&The ampersand (&) separates paths which together specify an intersection. Intersection has higher precedence to union. For example, the path //a/* & //*@name | //b/* is considered to be (//a/* & //*@name) | //b/*, not //a/* & (//*@name | //b/*). There are no parenthesis for grouping in actual path expressions.!An odd number of initial bangs (!) will negate the following clause, up to a pipe (|) or ampersand (&). An even number of initial bangs will have no effect.Examples:The following are some examples of paths.//*This matches any path. Attaching attributes to this path will apply them to all objects.//*@nameThis matches the name attribute of all objects.//*/*This matches any component that is not at the top-level.!//a//* & //b//*This matches any path that has a b component and not an a component.
