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

RUBY | = | File.join(Config::CONFIG['bindir'], Config::CONFIG['ruby_install_name']) |
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 583 583: def ruby(*args,&block) 584: if Hash === args.last 585: options = args.pop 586: else 587: options = {} 588: end 589: if args.length > 1 then 590: sh(*([RUBY] + args + [options]), &block) 591: else 592: sh("#{RUBY} #{args}", options, &block) 593: end 594: 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 600 600: def safe_ln(*args) 601: unless LN_SUPPORTED[0] 602: cp(*args) 603: else 604: begin 605: ln(*args) 606: rescue Errno::EOPNOTSUPP, Errno::EXDEV 607: LN_SUPPORTED[0] = false 608: cp(*args) 609: end 610: end 611: 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 557 557: def sh(*cmd, &block) 558: if Hash === cmd.last then 559: options = cmd.pop 560: else 561: options = {} 562: end 563: unless block_given? 564: show_command = cmd.join(" ") 565: show_command = show_command[0,42] + "..." if show_command.length > 45 566: block = lambda { |ok, status| 567: ok or fail "Command failed with status (#{status.exitstatus}): [#{show_command}]" 568: } 569: end 570: fu_check_options options, :noop, :verbose 571: fu_output_message cmd.join(" ") if options[:verbose] 572: unless options[:noop] 573: res = system(*cmd) 574: block.call(res, $?) 575: end 576: 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 618 618: def split_all(path) 619: head, tail = File.split(path) 620: return [tail] if head == '.' || tail == '/' 621: return [head, tail] if head == '/' 622: return split_all(head) + [tail] 623: end
