App::Sqitch::Plan::Depend - Sqitch dependency specification
my $depend = App::Sqitch::Plan::Depend->new(
plan => $plan,
App::Sqitch::Plan::Depend->parse('!proj:change@tag')
);
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
"requires" attributes.
"new"
my $depend = App::Sqitch::Plan::Depend->new(%params);
Instantiates and returns a App::Sqitch::Plan::Line object. Parameters:
- "plan"
- The plan with which the dependency is associated.
Required.
- "project"
- Name of the project. Required.
- "conflicts"
- Boolean to indicate whether the dependency is a conflicting
dependency.
- "change"
- The name of the change.
- "tag"
- The name of the tag claimed as the dependency.
- "id"
- The ID of a change. Mutually exclusive with
"change" and "tag".
"parse"
my %params = App::Sqitch::Plan::Depend->parse($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.
"plan"
my $plan = $depend->plan;
Returns the App::Sqitch::Plan object with which the dependency specification is
associated.
"conflicts"
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).
"required"
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).
"type"
say $depend->type;
Returns a string indicating the type of dependency, either "require"
or "conflict".
"project"
my $proj = $depend->project;
Returns the name of the project with which the dependency is associated.
"got_project"
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.
"change"
my $change = $depend->change;
Returns the name of the change, if any. If "undef" is returned, the
dependency is a tag-only dependency.
"tag"
my $tag = $depend->tag;
Returns the name of the tag, if any. If "undef" is returned, the
dependency is a change-only dependency.
"id"
Returns the ID of the change if the dependency was specified as an ID, or if the
dependency is a local dependency.
"got_id"
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.
"resolved_id"
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.
"is_external"
Returns true if the dependency references a change external to the current
project, and false if it is part of the current project.
"is_internal"
The opposite of "is_external()": returns true if the dependency is in
the internal (current) project, and false if not.
"key_name"
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.
"as_string"
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.
"as_plan_string"
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
"!".
