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
