SYNOPSIS

    use Statocles::Util qw( dircopy );

DESCRIPTION

This module contains some utility functions to help reduce non-core dependencies.

SUBROUTINES

trim

    my $trimmed = trim $untrimmed;

Trim the leading and trailing whitespace from the given scalar.

dircopy

    dircopy $source, $destination;

Copy everything in $source to $destination, recursively.

run_editor

    my $was_run = run_editor( $path );

Invoke the user's text editor (from the EDITOR environment variable) to edit the given path. Returns true if an editor was invoked, false otherwise. If the editor was not able to be invoked (EDITOR was set but could not be run), an exception is thrown.

uniq_by

    my @uniq_links = uniq_by { $_->href } @links;

Filter a list into its unique items based on the result of the passed-in block. This lets us get unique links from their href attribute.

derp

    derp "This feature is deprecated in file '%s'", $file;

Print out a deprecation message as a warning. A message will only be printed once for each set of arguments.
