I made a little add-on that sync a script.py filepath to a text target inside of Blender, it's quite handy for me because I like Sublime text editor more than the Blender's native text editor.

I also made a function that detects if the there's "EXECUTE" in the first line of the script. if it is so, the script will automatically be executed inside of Blender. so I can execute a script from within my text editor easily.
The only problem is: scripts that require a context will not work at all.
Somehow there's no context? So here's my question:
How to run a script from outside of Blender?
Or more precisely:
How to create an artificial context?
I tried multiple script execution methods like exec(compile(open(G_path).read(), G_path, 'exec')) but it never worked... Maybe using bpy.ops.text.run_script() can resolve the problem? But again, it needs a context, and an automatic change editor to the correct text? I don't know - I'm lost...
