Name ^

App::Sqitch::Plan::Line - Sqitch deployment plan line

Synopsis ^

  my $plan = App::Sqitch::Plan->new( sqitch => $sqitch );
  for my $line ($plan->lines) {
      say $line->as_string;
  }

Description ^

An App::Sqitch::Plan::Line represents a single line from a Sqitch plan file. Each object managed by an App::Sqitch::Plan object is derived from this class. This is actually an abstract base class. See App::Sqitch::Plan::Change, App::Sqitch::Plan::Tag, and App::Sqitch::Plan::Blank for concrete subclasses.

Interface ^

Constructors

new

  my $plan = App::Sqitch::Plan::Line->new(%params);

Instantiates and returns a App::Sqitch::Plan::Line object. Parameters:

plan

The App::Sqitch::Plan object with which the line is associated.

name

The name of the line. Should be empty for blank lines. Tags names should not include the leading @.

lspace

The white space from the beginning of the line, if any.

lopspace

The white space to the left of the operator, if any.

operator

An operator, if any.

ropspace

The white space to the right of the operator, if any.

rspace

The white space after the name until the end of the line or the start of a note.

note

A note. Does not include the leading #, but does include any white space immediate after the # when the plan file is parsed.

Accessors

plan

  my $plan = $line->plan;

Returns the plan object with which the line object is associated.

name

  my $name = $line->name;

Returns the name of the line. Returns an empty string if there is no name.

lspace

  my $lspace = $line->lspace.

Returns the white space from the beginning of the line, if any.

rspace

  my $rspace = $line->rspace.

Returns the white space after the name until the end of the line or the start of a note.

note

  my $note = $line->note.

Returns the note. Does not include the leading #, but does include any white space immediate after the # when the plan file is parsed. Returns the empty string if there is no note.

Instance Methods

format_name

  my $formatted_name = $line->format_name;

Returns the name of the line properly formatted for output. For tags, it's the name with a leading @. For all other lines, it is simply the name.

format_operator

  my $formatted_operator = $line->format_operator;

Returns the formatted representation of the operator. This is just the operator an its associated white space. If neither the operator nor its white space exists, an empty string is returned. Used internally by as_string().

format_content

  my $formatted_content $line->format_content;

Formats and returns the main content of the line. This consists of an operator and its associated white space, if any, followed by the formatted name.

format_note

  my $note = $line->format_note;

Returns the note formatted for output. That is, with a leading # and newlines encoded.

as_string

  my $string = $line->as_string;

Returns the full stringification of the line, suitable for output to a plan file.

request_note

  my $note = $line->request_note( for => 'add' );

Request the note from the user. Pass in the name of the command for which the note is requested via the for parameter. If there is a note, it is simply returned. Otherwise, an editor will be launched and the user asked to write one. Once the editor exits, the note will be retrieved from the file, saved, and returned. If no note was written, an exception will be thrown with an exitval of 1.

note_prompt

  my $prompt = $line->note_prompt( for => 'tag' );

Returns a localized string for use in the temporary file created by request_note(). Pass in the name of the command for which to prompt via the for parameter.
