List of all supported languages. @return [Hash]
Attributes
@return [Symbol] The type of code stored in this wrapper.
Public Class Methods
@param [String] filename The name of a file with code to be detected @param [Symbol] code_type
The type of code the `filename` contains
# File lib/puppet-debugger/code/code_file.rb, line 34 def initialize(filename, code_type = type_from_filename(filename)) @filename = filename @code_type = code_type end
Public Instance Methods
@return [String] The code contained in the current `@filename`.
# File lib/puppet-debugger/code/code_file.rb, line 40 def code path = abs_path @code_type = type_from_filename(path) File.read(path) end
Private Instance Methods
@raise [MethodSource::SourceNotFoundError] if the `filename` is not
readable for some reason.
@return [String] absolute path for the given `filename`.
# File lib/puppet-debugger/code/code_file.rb, line 51 def abs_path code_path.detect { |path| readable?(path) } || raise(SourceNotFound, "Cannot open #{@filename.inspect} for reading.") end
@return [Array] All the paths that contain code that Pry can use for its
API's. Skips directories.

@return [String]

@return [String]

@return [String]
# File lib/puppet-debugger/code/code_file.rb, line 85 def from_pwd File.expand_path(@filename, Dir.pwd) end
@param [String] path @return [Boolean] if the path, with or without the default ext,
is a readable file then `true`, otherwise `false`.
# File lib/puppet-debugger/code/code_file.rb, line 60 def readable?(path) File.readable?(path) && !File.directory?(path) || File.readable?(path << DEFAULT_EXT) end
@param [String] filename @param [Symbol] default (:unknown) the file type to assume if none could be
detected.
@return [Symbol, nil] The CodeRay type of a file from its extension, or
`nil` if `:unknown`.
