    • createDefaultCompletionCellRenderer

      protected ListCellRenderer<Object> createDefaultCompletionCellRenderer()

      Returns:
      The default renderer for the completion list.

      public static File getDefaultPerlInstallLocation()
      Returns the location of the first Perl install located on the user's PATH.
      Returns:
      The "default" location at which Perl is installed.
      See Also:

    • getPerlInstallLocation

      public static File getPerlInstallLocation()
      Returns the Perl install that is being used for syntax checking.

    • getParser

      private PerlParser getParser()
      Returns the shared parser, lazily creating it if necessary.

    • getParser

      public PerlParser getParser(org.fife.ui.rsyntaxtextarea.RSyntaxTextArea textArea)
      Returns the Perl parser running on a text area with this Perl language support installed.
      Parameters:
      textArea - The text area.
      Returns:
      The Perl parser. This will be null if the text area does not have this PerlLanguageSupport installed.

    • getProvider

      private PerlCompletionProvider getProvider()
      Lazily creates the shared completion provider instance for Perl.
      Returns:
      The completion provider.
