NAME ^

ExtUtils::ModuleMaker::StandardText - Methods used within ExtUtils::ModuleMaker

DESCRIPTION ^

The methods described below are 'quasi-private' methods which are called by the publicly available methods of ExtUtils::ModuleMaker and ExtUtils::ModuleMaker::Interactive. They are 'quasi-private' in the sense that they are not intended to be called by the everyday user of ExtUtils::ModuleMaker. Nothing prevents a user from calling these methods, but they are documented here primarily so that users writing plug-ins for ExtUtils::ModuleMaker's standard text will know what methods need to be subclassed.

The methods below are called in ExtUtils::ModuleMaker::complete_build() but not in that same package's new(). For methods called in new(), please see ExtUtils::ModuleMaker::Initializers.

The descriptions below are presented in hierarchical order rather than alphabetically. The order is that of ''how close to the surface can a particular method called?'', where 'surface' means being called within ExtUtils::ModuleMaker::complete_build(). So methods called within complete_build() are described before methods which are only called within other quasi-private methods. Some of the methods described are also called within ExtUtils::ModuleMaker::Interactive methods. And some quasi-private methods are called within both public and other quasi-private methods. Within each heading, methods are presented more or less as they are first called within the public or higher-order quasi-private methods.

Happy subclassing!

process_attribute()

  Usage     : $self->process_attribute($module, @keys) 
              within block_begin(), text_test(),
              text_pm_file(),  block_pod(), complete_build()
  Purpose   : 
              For the particular .pm file now being processed (value of the
              NAME key of the first argument: $module), see if there exists a
              key whose name is the second argument.  If so, return it.  
              Otherwise, return the value of the key by that name in the
              EU::MM object.  If we have a two-level hash (currently only in
              License_Parts, process down to that level.
  Arguments : First argument is a reference to an anonymous hash which has at
              least one element with key NAME and value of the module being 
              processed.  Second is an array of key names, although in all but
              one case it's a single-element (NAME) array.
  Comment   : [The method's name is very opaque and not self-documenting.
              Function of the code is not easily evident.  Rename?  Refactor?]

  Argument  : $module: pointer to the module being built
              (as there can be more than one module built by EU::MM);
              for the primary module it is a pointer to $self
  Throws    : n/a
  Comment   : This method is a likely candidate for alteration in a subclass
              E.g., some may prefer this info to appear in POD rather than
              inline comments.

block_new_method()

  Usage     : $self->block_new_method() within text_pm_file()
  Purpose   : Build 'new()' method as part of a pm file
  Returns   : String holding sub new.
  Argument  : $module: pointer to the module being built
              (as there can be more than one module built by EU::MM);
              for the primary module it is a pointer to $self
  Throws    : n/a
  Comment   : This method is a likely candidate for alteration in a subclass,
              e.g., pass a single hash-ref to new() instead of a list of
              parameters.

block_include_file_in_pm()

  Usage     : $self->block_include_file_in_pm() within text_pm_file()
  Purpose   : Include text from an arbitrary file on disk in .pm file,

  Argument  : $module: pointer to the module being built
              (as there can be more than one module built by EU::MM);

  Throws    : n/a
  Comment   : References $self->{INCLUDE_FILE_IN_PM}, whose value must be a
              path to a single, readable file

block_pod()

  Usage     : $self->block_pod($module) inside text_pm_file()
  Purpose   : Compose the main POD section within a pm file
  Returns   : String holding main POD section
  Argument  : $module: pointer to the module being built
              (as there can be more than one module built by EU::MM);

All Other Methods

death_message()

  Usage     : $self->death_message( [ I<list of error messages> ] ) 
              in validate_values; create_directory; print_file
  Purpose   : Croaks with error message composed from elements in the list
              passed by reference as argument
  Returns   : [ To come. ]
  Argument  : Reference to an array holding list of error messages accumulated
  Comment   : Different functioning in modulemaker interactive mode

log_message()

  Usage     : $self->log_message( $message ) in print_file; 
  Purpose   : Prints log_message (currently, to STDOUT) if $self->{VERBOSE}
  Returns   : n/a
  Argument  : Scalar holding message to be logged
  Comment   : 

pod_section()

  Usage     : $self->pod_section($heading, $content) within 
              block_pod()
  Purpose   : When writing POD sections, you have to 'escape' 
              the POD markers to prevent the compiler from treating 
              them as real POD.  This method 'unescapes' them and puts header
              and closer around individual POD headings within pm file.
  Arguments : Variables holding POD section name and text of POD section.

pod_wrapper()

  Usage     : $self->pod_wrapper($string) within block_pod()
  Purpose   : When writing POD sections, you have to 'escape' 
              the POD markers to prevent the compiler from treating 
              them as real POD.  This method 'unescapes' them and puts header
              and closer around main POD block in pm file, along with warning
              about stub documentation.
  Argument  : String holding text of POD which has been built up 
              within block_pod().
  Comment   : $head and $tail inside pod_wrapper() are optional and, in a 
              subclass, could be redefined as empty strings;
              but $cutline is mandatory as it supplies the last =cut
