Running Python interactively from within Sublime Text 2

Question

I have looked at all the answers on this forum but I'm missing something. I want to be able to hit Cmd+B while editing a Python file "myfile.py" in Sublime Text 2.

This should open up a Python shell that loads my file and returns me to the interactive prompt so the namespace in my Python script is available.

Setting the -i option in the build setting still closes the interpreter (see below)

I downloaded sublimeREPL but I'm not sure how to set the -i option.
Any help is appreciated

Solution 1

ok, thanks to sneawo for the hints! Here's my first cut at doing this.

Step 1. Create a plugin pydev, (from Tools->New Plugin) which creates a command 'pydev'

import sublime, sublime_plugin

class PydevCommand(sublime_plugin.WindowCommand):
    def run(self):
        self.window.run_command('set_layout', {"cols":[0.0, 1.0], "rows":[0.0, 0.5, 1.0], "cells":[[0, 0, 1, 1], [0, 1, 1, 2]]})
        self.window.run_command('repl_open',{"type": "subprocess",
                                             "encoding": "utf8",
                                             "cmd": ["python2.7", "-i", "-u", "$file"],
                                             "cwd": "$file_path",
                                             "syntax": "Packages/Python/Python.tmLanguage",
                                             "external_id": "python2.7"
                                             })
        self.window.run_command('move_to_group', { "group": 1 }) 

Step 2. Create a new key binding in the Preferences->Key-Bindings-user

{"keys": ["f5"], "command": "pydev"}

Now pressing f5 (on the Mac it will be fn+f5 by default) does the trick-it will start the python interpreter in a repl tab, set the layout to two-window horizontal and move the repl tab to the lower window.

This is pretty basic in that it doesn't check to see what the current layout is and simply sets the layout to 2-horizontal. Will probably spruce up the code to do some checking and simply add a horizontal window to the existing layout. Also would be good to remove the horizontal buffer when the repl tab is closed.

Solution 2

Try to update your user keybindings:

[
    { "keys": ["super+shift+r"], "command": "repl_open", 
                 "caption": "Python",
                 "mnemonic": "p",
                 "args": {
                    "type": "subprocess",
                    "encoding": "utf8",
                    "cmd": ["python", "-i", "-u", "$file"],
                    "cwd": "$file_path",
                    "syntax": "Packages/Python/Python.tmLanguage",
                    "external_id": "python"
                    } 
    }
]

Thanks! this is exactly what I needed!! Is it possible to open the repl terminal as a split window horizontally or as a an external window?

[sneawo]

I think it's possible with macro stackoverflow.com/questions/9646552/…

[dbn]

Wouldn't this make more sense as a build rule?

[minerals]

this does not work for windows, getting error system cannot find the file specified. Can you please tip what should be changed?

[dbn]

This looks exactly like the default build rule. Do you think that this does something different from the default build rule?

A note: this may break when trying to access dictionaries. Adding "extend_env": {"PYTHONIOENCODING": "utf-8"} to the command arguments fixes this issue.

Just wonder if it's possible like with REPL:R to send stuff from a script to an already existing REPL console.

[hhh]

Great! Is it possible to run the file in a REPL window already open ?
