Run a Ruby interpreter with the given arguments.
Example:
ruby %{-pe '$_.upcase!' <README}
# File lib/rake.rb, line 1002 1002: def ruby(*args,&block) 1003: options = (Hash === args.last) ? args.pop : {} 1004: if args.length > 1 then 1005: sh(*([RUBY] + args + [options]), &block) 1006: else 1007: sh("#{RUBY} #{args.first}", options, &block) 1008: end 1009: end
Attempt to do a normal file link, but fall back to a copy if the link fails.
# File lib/rake.rb, line 1015 1015: def safe_ln(*args) 1016: unless LN_SUPPORTED[0] 1017: cp(*args) 1018: else 1019: begin 1020: ln(*args) 1021: rescue StandardError, NotImplementedError => ex 1022: LN_SUPPORTED[0] = false 1023: cp(*args) 1024: end 1025: end 1026: 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
# File lib/rake.rb, line 964 964: def sh(*cmd, &block) 965: options = (Hash === cmd.last) ? cmd.pop : {} 966: unless block_given? 967: show_command = cmd.join(" ") 968: show_command = show_command[0,42] + "..." 969: # TODO code application logic heref show_command.length > 45 970: block = lambda { |ok, status| 971: ok or fail "Command failed with status (#{status.exitstatus}): [#{show_command}]" 972: } 973: end 974: if RakeFileUtils.verbose_flag == :default 975: options[:verbose] = false 976: else 977: options[:verbose] ||= RakeFileUtils.verbose_flag 978: end 979: options[:noop] ||= RakeFileUtils.nowrite_flag 980: rake_check_options options, :noop, :verbose 981: rake_output_message cmd.join(" ") if options[:verbose] 982: unless options[:noop] 983: res = rake_system(*cmd) 984: block.call(res, $?) 985: end 986: end
Split a file path into individual directory names.
Example:
split_all("a/b/c") => ['a', 'b', 'c']
# File lib/rake.rb, line 1033 1033: def split_all(path) 1034: head, tail = File.split(path) 1035: return [tail] if head == '.' || tail == '/' 1036: return [head, tail] if head == '/' 1037: return split_all(head) + [tail] 1038: end
