Synopsis

         my $plan = App::Sqitch::Plan->new( sqitch => $sqitch );

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.

           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

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

       "lopspace"

           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"

       "note"

         my $note = $line->note.

       immediate after the "#" when the plan file is parsed. Returns the empty string if there is

   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.
