This plugin adds Python completions and some IDE-like functions to Sublime Text 3, through the use of the Rope library. It is a complete rewrite of SublimeRope for ST2. It should be a lot faster and easier to use than SublimeRope was.

In contrast to SublimeRope, it does use the built in Python only for UI-related functions, the completions and refactorings are calculated using the exact same python interpreter you use for your project (e.g. the one in your virtualenv). This eliminates a lot of small and big problems that SublimeRope had, e.g., not recognizing dict comprehensions because Python2.6 is used in ST2, or not recognizing some of your libraries because you did not configure all the paths etc.. Everything your projects interpreter sees, should be visible to SublimePython -> easier configuration.

I also added a lot caching throughout the underlying Rope library which improved completion performance by several orders of magnitude. I hope no functionality breaks because of this ;-)


Python location

The only necessary configuration is pointing SublimePythonIDE at the correct Python interpreter to use. There are four mechanisms for detecting Python that are used in the following order:

  • Checking the option "python_interpreter" in project settings (see below)
  • Auto-detecting a virtual environment (in "venv" or $WORKON_HOME for virtualenvwrapper)
  • Reading a #! (shebang) line in the active file
  • Auto-detecting the system Python from $PATH

The option "python_interpreter" can be set in the projects settings (Project->Edit Project). Example:

    "folders": [
           "path": "XYZ"
            "path": "ABC"
    "settings": {
        "python_interpreter": "/path/to/some/virtualenv/bin/python"

This is also the way to select a virtualenv (point it to the interpreter in the venv) and thus get the completions/definitions for you project working.

To suppress the "Could not find Python dialog", save the following setting:

"suppress_python_not_found_error": false,

Imports location

SublimePythonIDE will also look up imports relative to the project root directory (the top directory of your project).

In cases where the project directory is outside of your root python module, you may optionally set a custom source root directory in the project settings:

    "folders": [
           "path": "XYZ"
    "settings": {
        "src_root": "XYZ/THE_ACTUAL_SRC"
        "python_interpreter": "/path/to/some/virtualenv/bin/python",

See Packages/SublimePythonIDE/SublimePython.sublime-settings for other options. As with all ST packages, copy this file into your Packages/User folder and editing the copy there.
