LN_SUPPORTED | = | [true] |
Public Instance methods
Run a Ruby interpreter with the given arguments.
Example:
ruby %{-pe '$_.upcase!' <README}
[ show source ]
# File lib/rake.rb, line 738 738: def ruby(*args,&block) 739: if Hash === args.last 740: options = args.pop 741: else 742: options = {} 743: end 744: if args.length > 1 then 745: sh(*([RUBY] + args + [options]), &block) 746: else 747: sh("#{RUBY} #{args}", options, &block) 748: end 749: end
Attempt to do a normal file link, but fall back to a copy if the link fails.
[ show source ]
# File lib/rake.rb, line 755 755: def safe_ln(*args) 756: unless LN_SUPPORTED[0] 757: cp(*args) 758: else 759: begin 760: ln(*args) 761: rescue StandardError, NotImplementedError 762: LN_SUPPORTED[0] = false 763: cp(*args) 764: end 765: end 766: end
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
[ show source ]
# File lib/rake.rb, line 712 712: def sh(*cmd, &block) 713: if Hash === cmd.last then 714: options = cmd.pop 715: else 716: options = {} 717: end 718: unless block_given? 719: show_command = cmd.join(" ") 720: show_command = show_command[0,42] + "..." if show_command.length > 45 721: block = lambda { |ok, status| 722: ok or fail "Command failed with status (#{status.exitstatus}): [#{show_command}]" 723: } 724: end 725: fu_check_options options, :noop, :verbose 726: fu_output_message cmd.join(" ") if options[:verbose] 727: unless options[:noop] 728: res = system(*cmd) 729: block.call(res, $?) 730: end 731: end
Split a file path into individual directory names.
Example:
split_all("a/b/c") => ['a', 'b', 'c']
[ show source ]
# File lib/rake.rb, line 773 773: def split_all(path) 774: head, tail = File.split(path) 775: return [tail] if head == '.' || tail == '/' 776: return [head, tail] if head == '/' 777: return split_all(head) + [tail] 778: end
