app::kgb::change
App::KGB::Change(3pm) User Contributed Perl Documentation App::KGB::Change(3pm)
NAME
App::KGB::Change - a single file change
SYNOPSIS
my $c = App::KGB::Change->new(
{ action => "M", prop_change => 1, path => "/there" } );
print $c;
my $c = App::KGB::Change->new("(M+)/there");
DESCRIPTION
App::KGB::Change encapsulates a single path change from a given change set (or commit).
App::KGB::Change overloads the "" operator in order to provide a default string representation of changes.
FIELDS
action (mandatory)
The action performed on the item. Possible values are:
M The path was modified.
A The path was added.
D The path was deleted.
R The path was replaced.
path (mandatory)
The path that was changed.
prop_change
Boolean. Indicated that some properties of the path, not the content were changed.
CONSTRUCTOR
new ( { initial values } )
More-or-less standard constructor.
It can take a hashref with keys all the field names (See ).
Or, it can take a single string, which is de-composed into components.
See for examples.
METHODS
as_string()
Return a string representation of the change. Used by the "" overload. The resulting string is suitable for feeding the constructor
if needed.
CLASS METHODS
detect_common_dir("changes")
Given an arrayref of changes (instances of APP::KGB::Change), detects the longest path that is common to all of them. All the changes'
paths are trimmed from the common part.
Example:
foo/b
foo/x
foo/bar/a
would return 'foo' and the paths would be trimmed to
b
x
bar/a
