How can I send a string in TextMate to an irb process running in a terminal window?

Question

I often code with the TextMate window open and the irb process in the terminal window next to it. I want to be able to press a key sequence in TextMate, which does the following:

• Copies the current selection, or if not, the current line.
• Inserts it into the topmost terminal window on which irb is running.
• Press the enter button to execute the line of code in the irb window.

I used this style of interactive development when coding in R and found it very convenient. I'm sure emacs and SLIME will also allow you to work this way. Is this possible with Ruby and TextMate?

Answer 1

To do this, create a Bundle command and a keyboard shortcut.

• In TextMate, go to Bundles -> Bundle Editor
• Create a new team inside our own package. Name it Run in Terminal
• Set "Save" to "No", set "Input" to the selected text and "or" to "Line".
• Set "Exit to Uninstall"
• In Activation, select your own shortcut. I chose Apple Shift U
• Paste the command below into the "Command" field (formatting is causing me problems).
• Close the Bundle Editor, then select Bundles → Bundle Editor → Reload Bundles
• Create a new document containing the string "puts" Hello World "
• Open IRB in terminal
• Select the line you just wrote in Textmate and press the key combination.
• Watch “Hello World” appear on IRB.

Command:

#!/usr/bin/ruby input = STDIN.gets `osascript << EOF tell application "Terminal" activate end tell delay 1 tell application "System Events" keystroke "#{input.gsub('"', '\"')}" keystroke return end tell EOF`

Suppose you do not want to view the terminal, but instead want the result to appear in TextMate, for example, in the Smalltalk workspace.

Essentially, you want to run ruby ​​in a text mat, but you want variables to be remembered between executions. You can have it.

(Thanks to stef for instructions on adding a new command)

• Run gem install daemons
• Launch the irb server. The file is located below.
• In TextMate, go to Bundles -> Bundle Editor
• Create a new team inside our own package. Name it Run in Terminal
• Set "Save" to "No", set "Input" to the selected text and "or" to "Line".
• Set "Exit to Uninstall"
• In Activation, select your own shortcut. I chose Apple Shift U
• Paste the command below into the "Command" field (formatting is causing me problems).
• Close the Bundle Editor, then select Bundles → Bundle Editor → Reload Bundles
• Create a new document containing the lines @@hi = "Hello World" and @@hi + "ya"
• Select the first line you just wrote in Textmate, and press the key combination.
• Do the same with the second line
• Watch how "hiya" appears in a text mat.

Irb server:

 #!/usr/bin/env ruby -w require 'rubygems' require 'daemons' require 'socket' LARGE = 100000000 PIPE = "/tmp/.irbservepipe" def kill_pipe `rm -f #{PIPE}` end def respond_to(pipe) inp = pipe.recv LARGE inp.nil? and return begin out = eval(inp) rescue Exception => e out = e end pipe.send out.inspect, 0 end def ensure_server ["EXIT", "INT", "HUP", "TERM"].each {|ea| trap( ea ) { kill_pipe }} File.exists?(PIPE) and kill_pipe server = UNIXServer.new(PIPE) loop { c = server.accept respond_to c c.close } end Daemons.daemonize ensure_server 

Command:

 #!/usr/bin/env macruby -w require 'socket' LARGE = 100000000 PIPE = "/tmp/.irbservepipe" input = STDIN.read socket = UNIXSocket.new(PIPE) socket.send input, 0 puts socket.recv LARGE
