Instance Method Details

#__DIR__ ⇒ Object

This is similar to __FILE__ and __LINE__, and returns a String representing the directory of the current file is. Unlike __FILE__ the path returned is absolute.

This method is convenience for the

File.expand_path(File.dirname(__FILE__))

idiom.

# File 'lib/ramaze/snippets/kernel/__dir__.rb', line 18

def __DIR__()
  filename = caller[0][/^(.*):/, 1]
  File.expand_path(File.dirname(filename))
end

#acquire(*globs) ⇒ Object

Require all .rb and .so files on the given globs, utilizes Dir::[].

Examples:

# Given following directory structure:
# src/foo.rb
# src/bar.so
# src/foo.yaml
# src/foobar/baz.rb
# src/foobar/README

# requires all files in 'src':
acquire 'src/*'

# requires all files in 'src' recursive:
acquire 'src/**/*'

# require 'src/foo.rb' and 'src/bar.so' and 'src/foobar/baz.rb'
acquire 'src/*', 'src/foobar/*'

def acquire *globs
  globs.flatten.each do |glob|
    Dir[glob].each do |file|
      require file if file =~ /\.(rb|so)$/
    end
  end
end

#constant(const) ⇒ Object

Original from Trans (Facets 1.4.5) This is similar to Module#const_get but is accessible at all levels, and, unlike const_get, can handle module hierarchy.

constant("Fixnum")                  # -> Fixnum
constant(:Fixnum)                   # -> Fixnum

constant("Process::Sys")            # -> Process::Sys
constant("Regexp::MULTILINE")       # -> 4

require 'test/unit'
Test.constant("Unit::Assertions")   # -> Test::Unit::Assertions
Test.constant("::Test::Unit")       # -> Test::Unit

def constant(const)
  const = const.to_s.dup
  base = const.sub!(/^::/, '') ? Object : ( self.kind_of?(Module) ? self : self.class )
  const.split(/::/).inject(base){ |mod, name| mod.const_get(name) }
end

#pretty_inspect ⇒ Object

returns a pretty printed object as a string.
