assign multiple commands to the same key binding in ST2

Question

I have "Super+Alt+left" to set the layout so that the left pane is wider (66%) of the screen:

current ST2 layout

I would also like the same key stroke to focus on the left tab so that I can start typing immediately without a click or Ctrl + 0.

Here's what I tried. I added a new plugin:

import sublime, sublime_plugin

class ExpandAndFocusLeftPane(sublime_plugin.TextCommand):
  def run(self, edit):
    self.view.run_command("focus_group", "args": {"group": 0})
    self.view.run_command("set_layout", "args": {
       "cols": [0.0, 0.66, 1.0],
      "rows": [0.0, 1.0],
      "cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
      })

And I bound "Super+Alt+Left" to this new command.

{
  "keys": ["super+alt+left"],
  "command": "expand_and_focus_left_pane",
  "args":
  {
    "cols": [0.0, 0.66, 1.0],
    "rows": [0.0, 1.0],
    "cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
  }
},

But it still does not do what i want it to do. Any ideas ?

Are you seeing any effect from this key combination at all? Double-check your Default (OSX).sublime-keymap files (both Default and User) to make sure you haven't assigned this combo anywhere else. — MattDMo

First, you have to check if the "focus_group" and "set_layout" commands work as expected. Open the console (View->Show Console) and try this:

view.run_command("focus_group", "args": {"group": 0})

You'll get a:

  File "<string>", line 1
    view.run_command("focus_group", "args": {"group": 0})
                                          ^
SyntaxError: invalid syntax

If you change it to

view.run_command("focus_group", {"group": 0})

it won't work. That's because "focus_group" and "set_layout" are window commands, so this will work:

window.run_command("focus_group", {"group": 0})
window.run_command("set_layout", { "cols": [0.0, 0.66, 1.0], "rows": [0.0, 1.0],  "cells": [[0, 0, 1, 1], [1, 0, 2, 1]] })

So your plugin should extend sublime_plugin.WindowCommand and use self.window:

class ExpandAndFocusLeftPaneCommand(sublime_plugin.WindowCommand):
    def run(self):
        self.window.run_command("focus_group", {"group": 0})
        self.window.run_command("set_layout", {
           "cols": [0.0, 0.66, 1.0],
          "rows": [0.0, 1.0],
          "cells": [[0, 0, 1, 1], [1, 0, 2, 1]]
        })

And ExpandAndFocusLeftPane should be ExpandAndFocusLeftPaneCommand.

What name should I use to save the plugin file? In which directory? Is there a convention?

And finally, how do I set up the Key binding for this command?

dusan Over a year ago

@gprasant { "keys": ["super+alt+left"], "command": "expand_and_focus_left_pane" } should work. You can test it using window.run_command("expand_and_focus_left_pane")

dusan Over a year ago

@gprasant Go to Preferences->Browse Packages, and there create a directory (eg: ExpandPane) and put the plugin file there (make sure it ends with .py)
