Overview

Parse a non-source file. We basically take the whole thing as one big comment.

Class Attribute Summary

::RDoc::Parser - Inherited

.parsers

An Array of arrays that maps file extension (or name) regular expressions to parser classes that will parse matching filenames.

Class Method Summary

::RDoc::Parser - Inherited

.alias_extension

::RDoc::Alias an extension to another extension.
.binary?

Determines if the file is a “binary” file which basically means it has content that an ::RDoc::RDoc parser shouldn't try to consume.
.can_parse

Return a parser that can handle a particular extension.
.can_parse_by_name

Returns a parser that can handle the extension for #file_name.
.check_modeline

Returns the file type from the modeline in #file_name
.for

Finds and instantiates the correct parser for the given #file_name and #content.
.new

Creates a new ::RDoc::Parser storing top_level, #file_name, #content, options and stats in instance variables.
.parse_files_matching

Record which file types this parser can understand.
.process_directive

Processes common directives for CodeObjects for the C and Ruby parsers.
.remove_modeline

Removes an emacs-style modeline from the first line of the document.
.use_markup

If there is a markup: parser_name comment at the front of the file, use it to determine the parser.
.zip?

Checks if file is a zip file in disguise.

Instance Attribute Summary

::RDoc::Parser - Inherited

#file_name

The name of the file being parsed.

    #remove_private_comment(comment)  
  



  

    

Removes private comments.



Unlike Comment#remove_private this implementation only looks for two dashes at the beginning of the line.  Three or more dashes are considered to be a rule and ignored.
