Rush is a shell with ruby syntax and idioms. This presentation goes over how to use it and embed it in other applications.

4. Install and Run $ sudo gem install rush $ rush rush> home=> localhost:/Users/schlueter/

5. No Working Directory $ home => localhost:/Users/schlueter $ root=> localhost://// $ rushmate = home[ "mydev/github/rushmate/" ] => localhost:/Users/schlueter/mydev/github/rushmate/

6. But ls Still Works $ home[ "mydev/github/rushmate/" ].ls /Users/schlueter/mydev/github/rushmate/ coverage/ lib/ test/ History.txt MIT-LICENSE Manifest.txt

7. Make a Variable $ rushmate = home[ "mydev/github/rushmate/" ]

8. File Manipulation http://flickr.com/photos/takashi/18862634/

9. Rename # assign a file to a variable $ file = rushmate[ 'app/models/rushmate.rb' ] $ file.rename 'russian_mate.rb'

10. Duplicate a File $ file = rushmate[ 'README' ] $ file.duplicate 'README.markdown'

11. Copy Different Directory $ file = rushmate[ 'README' ] $ file.copy_to other_project[ 'README' ]

12. Move $ file = rushmate[ 'README' ] $ file.move_to home[ 'Desktop/' ]

13. Write a File $ file = rushmate[ 'README' ] $ file.write "You Read Me"

14. Read a File $ rushmate[ "README" ].contents You Read Me

15. File Globbing

16. Basic Globbing $ rushmate[ "**/*.rb" ] .../mydev/github/rushmate/lib/rushmate.rb.../mydev/github/rushmate/lib/rushmate/command.rb.../mydev/github/rushmate/lib/rushmate/exit.rb ... => 9 x Rush :: File

17. Glob into an Editor $ rushmate[ "**/*.rb" ].vi $ rushmate[ "**/*.rb" ].mate

18. Operate on Results $ rails_proj[ '**/*.rhtml' ].each { | f | f.rename f.name.gsub( / rhtml/ , '.html.erb' ) }

19. Results Are an Array $ rushmate[ "**/*.rb" ].reject {| f | f.name.match( /test.rb/ )} Go Nuts! $ rails_project[ "**/*.rhtml" ] + rails_project[ "**/*.html.erb" ]

20. embed http://flickr.com/photos/liamngls/413522957/ Rush :: EmbeddableShell . new .execute_in_shell do #anything in here delegates to rush end

21. Sake Quick Index of RDoc task 'rdoc:local' => 'rush' do shell = Rush :: EmbeddableShell . new shell.execute_in_shell do end end ruby = root[ &quot;/Library/Ruby/Gems/1.8/&quot; ] indexes = ruby[ &quot;doc/*/rdoc/index.html&quot; ] hrefs = indexes.collect { | f | path = f.full_path text = path.match( /doc (.*) rdoc/ )[ 1 ] &quot;<a href= amp;quot; #{path} amp;quot; >#{text}</a>&quot; } home[ &quot;rdoc.html&quot; ].write hrefs.join( &quot;<br />&quot; ) home.bash( &quot;open rdoc.html&quot; )

22. sake rdoc:local

24. Refactoring http://flickr.com/photos/tonyjcase/2262229518/

25. Search $ work[ &quot;**/*.rb&quot; ].search( / Rushmate / ) .../test/user_input_test.rb => assert_equal(&quot;foo&quot;, Rushmate ::.../lib/rushmate/command.rb => module Rushmate .../lib/rushmate/exit.rb => module Rushmate ...7 matching files with 25 matching lines $ work[ &quot;**/*.rb&quot; ].search( / Rushmate / ).mate

27. Regex is your friend $ project_files.replace_contents! ( /User.authenticate *(.*), *(.*) / , 'User.authenticate( 2, 1)' ) User .authenticate(user, password) User .authenticate(password, user)

29. Real World Rush :: EmbeddableShell . new .execute_in_shell do end ff_processes = processes. filter ( :cmdline => /firefox/ ) if ff = ff_processes.select{| p | p.mem > 400000 }.first ff_cmdline = ff.cmdline ff.kill home.bash ff_cmdline, :background => true end

30. Permissions $ file.access = { :user_can => :read_and_write , :group_and_other_can => :read } $ file.access[ :user_can_read ] => true

31. Use BASH if you must $ rushmate.bash &quot;rm -rf .&quot; # D'oh!

32. Shell Locally Act Globally

33. Remote $ remote = Rush :: Box . new ( 'user@server.com' ) $ remote[ &quot;/u/app/current/REVISION&quot; ].contents => 160

34. Starts a Mongrel on Remote Server Use in production with caution

35. Customize # setup variables to common directories rushmate = home[ &quot;mydev/github/rushmate/&quot; ] # setup variables to common servers qa = Rush :: Box . new ( 'user@qa.local' ) ~/.rush/evn.rb

36. Cheap Backup def cheap_backup (directory) unless directory.dir? puts &quot;cheap backup only works on dirs&quot; return end backup_path = directory.path + &quot;/&quot; + directory.name + &quot;.bak&quot; if self [backup_path].exists? puts &quot;backup already exists&quot; else directory.duplicate(directory.name + &quot;.bak&quot; ) end end

37. Extend # allows you to run # directory.coverage def coverage self .rake( &quot;coverage&quot; ) end ~/.rush/commands.rb

38. Another Command def ruby_files self [ &quot;**/*.rb&quot; ] end $ rushmate.ruby_files .../mydev/github/rushmate/lib/rushmate.rb.../mydev/github/rushmate/lib/rushmate/command.rb.../mydev/github/rushmate/lib/rushmate/exit.rb ... => 9 x Rush::File

40. TextMate Rushmate :: Command . new { # find ruby files with the current word in textmate found_files = project_directory[ &quot;**/#{current_word.downcase}.rb&quot; ] if found_files.size == 1 found_files.mate else menu_files = found_files.collect { | f | f.full_path.gsub(project_directory.full_path, &quot;&quot; ) } project_directory[user_input.quick_menu_from_array(menu_files)].mate end }
