This a FileUtils extension that defines several additional commands to be added to the FileUtils utility functions.

RUBY_EXT = ((Config::CONFIG['ruby_install_name'] =~ /\.(com|cmd|exe|bat|rb|sh)$/) ? "" : Config::CONFIG['EXEEXT'])
RUBY = File.join( Config::CONFIG['bindir'], Config::CONFIG['ruby_install_name'] + RUBY_EXT). sub(/.*\s.*/m, '"\&"')
LN_SUPPORTED = [true]
Public Instance methods
ruby(*args,&block)

Run a Ruby interpreter with the given arguments.

Example:

  ruby %{-pe '$_.upcase!' <README}
      # File lib/rake.rb, line 1024
1024:   def ruby(*args,&block)
1025:     options = (Hash === args.last) ? args.pop : {}
1026:     if args.length > 1 then
1027:       sh(*([RUBY] + args + [options]), &block)
1028:     else
1029:       sh("#{RUBY} #{args.first}", options, &block)
1030:     end
1031:   end
safe_ln(*args)

Attempt to do a normal file link, but fall back to a copy if the link fails.

      # File lib/rake.rb, line 1037
1037:   def safe_ln(*args)
1038:     unless LN_SUPPORTED[0]
1039:       cp(*args)
1040:     else
1041:       begin
1042:         ln(*args)
1043:       rescue StandardError, NotImplementedError => ex
1044:         LN_SUPPORTED[0] = false
1045:         cp(*args)
1046:       end
1047:     end
1048:   end
sh(*cmd, &block)

Run the system command cmd. If multiple arguments are given the command is not run with the shell (same semantics as Kernel::exec and Kernel::system).

Example:

  sh %{ls -ltr}

  sh 'ls', 'file with spaces'

  # check exit status after command runs
  sh %{grep pattern file} do |ok, res|
    if ! ok
      puts "pattern not found (status = #{res.exitstatus})"
    end
  end
      # File lib/rake.rb, line 988
 988:   def sh(*cmd, &block)
 989:     options = (Hash === cmd.last) ? cmd.pop : {}
 990:     unless block_given?
 991:       show_command = cmd.join(" ")
 992:       show_command = show_command[0,42] + "..." unless $trace
 993:       # TODO code application logic heref show_command.length > 45
 994:       block = lambda { |ok, status|
 995:         ok or fail "Command failed with status (#{status.exitstatus}): [#{show_command}]"
 996:       }
 997:     end
 998:     if RakeFileUtils.verbose_flag == :default
 999:       options[:verbose] = true
1000:     else
1001:       options[:verbose] ||= RakeFileUtils.verbose_flag
1002:     end
1003:     options[:noop]    ||= RakeFileUtils.nowrite_flag
1004:     rake_check_options options, :noop, :verbose
1005:     rake_output_message cmd.join(" ") if options[:verbose]
1006:     unless options[:noop]
1007:       res = rake_system(*cmd)
1008:       status = $?
1009:       status = PseudoStatus.new(1) if !res && status.nil?
1010:       block.call(res, status)
1011:     end
1012:   end
split_all(path)

Split a file path into individual directory names.

Example:

  split_all("a/b/c") =>  ['a', 'b', 'c']
      # File lib/rake.rb, line 1055
1055:   def split_all(path)
1056:     head, tail = File.split(path)
1057:     return [tail] if head == '.' || tail == '/'
1058:     return [head, tail] if head == '/'
1059:     return split_all(head) + [tail]
1060:   end
