App::Sqitch::Plan::Depend - Sqitch dependency specification
my $depend = App::Sqitch::Plan::Depend->new(
plan => $plan,
An App::Sqitch::Plan::Line represents a single dependency from the dependency
list for a planned change. Is is constructed by App::Sqitch::Plan and included
in App::Sqitch::Plan::Change objects "conflicts" and
my $depend = App::Sqitch::Plan::Depend->new(%params);
Instantiates and returns a App::Sqitch::Plan::Line object. Parameters:
- The plan with which the dependency is associated.
- Name of the project. Required.
- Boolean to indicate whether the dependency is a conflicting
- The name of the change.
- The name of the tag claimed as the dependency.
- The ID of a change. Mutually exclusive with
"change" and "tag".
my %params = App::Sqitch::Plan::Depend->parse($string);
Parses a dependency specification as extracted from a plan and returns a hash
reference of parameters suitable for passing to "new()". Returns
"undef" if the string is not a properly-formatted dependency.
my $plan = $depend->plan;
Returns the App::Sqitch::Plan object with which the dependency specification is
say $depend->as_string, ' conflicts' if $depend->conflicts;
Returns true if the dependency is a conflicting dependency, and false if it is
not (in which case it is a required dependency).
say $depend->as_string, ' required' if $depend->required;
Returns true if the dependency is a required, and false if it is not (in which
case it is a conflicting dependency).
Returns a string indicating the type of dependency, either "require"
my $proj = $depend->project;
Returns the name of the project with which the dependency is associated.
Returns true if the "project" parameter was passed to the constructor
with a defined value, and false if it was not passed to the constructor.
my $change = $depend->change;
Returns the name of the change, if any. If "undef" is returned, the
dependency is a tag-only dependency.
my $tag = $depend->tag;
Returns the name of the tag, if any. If "undef" is returned, the
dependency is a change-only dependency.
Returns the ID of the change if the dependency was specified as an ID, or if the
dependency is a local dependency.
Returns true if the "id" parameter was passed to the constructor with
a defined value, and false if it was not passed to the constructor.
Change ID used by the engine when deploying a change. That is, if the dependency
is in the database, it will be assigned this ID from the database. If it is
not in the database, "resolved_id" will be undef.
Returns true if the dependency references a change external to the current
project, and false if it is part of the current project.
The opposite of "is_external()": returns true if the dependency is in
the internal (current) project, and false if not.
Returns the key name of the dependency, with the change name and/or tag,
properly formatted for passing to the "find()" method of
App::Sqitch::Plan. If the dependency was specified as an ID, rather than a
change or tag, then the ID will be returned.
Returns the project-qualified key name. That is, if there is a project name, it
returns a string with the project name, a colon, and the key name. If there is
no project name, the key name is returned.
my $string = $depend->as_string;
Returns the full stringification of the dependency, suitable for output to a
plan file. That is, the same as "as_string" unless
"conflicts" returns true, in which case it is prepended with
- Class representing a plan.
- The Sqitch command-line client.
