# frozen_string_literal: true require "rbconfig" require "fileutils" #-- # This a FileUtils extension that defines several additional commands to be # added to the FileUtils utility functions. module FileUtils # Path to the currently running Ruby program RUBY = ENV["RUBY"] || File.join( RbConfig::CONFIG["bindir"], RbConfig::CONFIG["ruby_install_name"] + RbConfig::CONFIG["EXEEXT"]). sub(/.*\s.*/m, '"\&"') # Run the system command +cmd+. If multiple arguments are given the command # is run directly (without the shell, same semantics as Kernel::exec and # Kernel::system). # # It is recommended you use the multiple argument form over interpolating # user input for both usability and security reasons. With the multiple # argument form you can easily process files with spaces or other shell # reserved characters in them. With the multiple argument form your rake # tasks are not vulnerable to users providing an argument like # <code>; rm # -rf /</code>. # # If a block is given, upon command completion the block is called with an # OK flag (true on a zero exit status) and a Process::Status object. # Without a block a RuntimeError is raised when the command exits non-zero. # # Examples: # # 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 # def sh(*cmd, &block) options = (Hash === cmd.last) ? cmd.pop : {} shell_runner = block_given? ? block : create_shell_runner(cmd) set_verbose_option(options) verbose = options.delete :verbose noop = options.delete(:noop) || Rake::FileUtilsExt.nowrite_flag Rake.rake_output_message sh_show_command cmd if verbose unless noop res = (Hash === cmd.last) ? system(*cmd) : system(*cmd, options) status = $? status = Rake::PseudoStatus.new(1) if !res && status.nil? shell_runner.call(res, status) end end def create_shell_runner(cmd) # :nodoc: show_command = sh_show_command cmd show_command = show_command[0, 42] + "..." unless $trace lambda do |ok, status| ok or fail "Command failed with status (#{status.exitstatus}): " + "[#{show_command}]" end end private :create_shell_runner def sh_show_command(cmd) # :nodoc: cmd = cmd.dup if Hash === cmd.first env = cmd.first env = env.map { |name, value| "#{name}=#{value}" }.join " " cmd[0] = env end cmd.join " " end private :sh_show_command def set_verbose_option(options) # :nodoc: unless options.key? :verbose options[:verbose] = (Rake::FileUtilsExt.verbose_flag == Rake::FileUtilsExt::DEFAULT) || Rake::FileUtilsExt.verbose_flag end end private :set_verbose_option # Run a Ruby interpreter with the given arguments. # # Example: # ruby %{-pe '$_.upcase!' <README} # def ruby(*args, &block) options = (Hash === args.last) ? args.pop : {} if args.length > 1 sh(*([RUBY] + args + [options]), &block) else sh("#{RUBY} #{args.first}", options, &block) end end LN_SUPPORTED = [true] # Attempt to do a normal file link, but fall back to a copy if the link # fails. def safe_ln(*args) if !LN_SUPPORTED[0] cp(*args) else begin ln(*args) rescue StandardError, NotImplementedError LN_SUPPORTED[0] = false cp(*args) end end end # Split a file path into individual directory names. # # Example: # split_all("a/b/c") => ['a', 'b', 'c'] # def split_all(path) head, tail = File.split(path) return [tail] if head == "." || tail == "/" return [head, tail] if head == "/" return split_all(head) + [tail] end end
