Run a Ruby interpreter with the given arguments.
Example:
ruby %{-pe '$_.upcase!' <README}
# File lib/rake.rb, line 1000 1000: def ruby(*args,&block) 1001: options = (Hash === args.last) ? args.pop : {} 1002: if args.length > 1 then 1003: sh(*([RUBY] + args + [options]), &block) 1004: else 1005: sh("#{RUBY} #{args.first}", options, &block) 1006: end 1007: end
Attempt to do a normal file link, but fall back to a copy if the link fails.
# File lib/rake.rb, line 1013 1013: def safe_ln(*args) 1014: unless LN_SUPPORTED[0] 1015: cp(*args) 1016: else 1017: begin 1018: ln(*args) 1019: rescue StandardError, NotImplementedError => ex 1020: LN_SUPPORTED[0] = false 1021: cp(*args) 1022: end 1023: end 1024: 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 962 962: def sh(*cmd, &block) 963: options = (Hash === cmd.last) ? cmd.pop : {} 964: unless block_given? 965: show_command = cmd.join(" ") 966: show_command = show_command[0,42] + "..." 967: # TODO code application logic heref show_command.length > 45 968: block = lambda { |ok, status| 969: ok or fail "Command failed with status (#{status.exitstatus}): [#{show_command}]" 970: } 971: end 972: if RakeFileUtils.verbose_flag == :default 973: options[:verbose] = true 974: else 975: options[:verbose] ||= RakeFileUtils.verbose_flag 976: end 977: options[:noop] ||= RakeFileUtils.nowrite_flag 978: rake_check_options options, :noop, :verbose 979: rake_output_message cmd.join(" ") if options[:verbose] 980: unless options[:noop] 981: res = rake_system(*cmd) 982: block.call(res, $?) 983: end 984: end
Split a file path into individual directory names.
Example:
split_all("a/b/c") => ['a', 'b', 'c']
# File lib/rake.rb, line 1031 1031: def split_all(path) 1032: head, tail = File.split(path) 1033: return [tail] if head == '.' || tail == '/' 1034: return [head, tail] if head == '/' 1035: return split_all(head) + [tail] 1036: end
