Edit/view the command functions referenced by the key binding JSON script in Sublime Text 3

Question

Here's a custom key binding I have in ST3:

{ "keys": ["super+shift+e"], "command": "open_dir", "args": {"dir": "$file_path", "file": "$file_name"} }

I would like to edit/view the command functions referenced in this JSON key binding (e.g. open_dir, which opens Finder). I want to see the code behind open_dir to see how it works.

The JSON file of this key binding is Default (OSX).sublime-keymap. I've done file searches in ~/Library/Application Support/Sublime Text 3/ as well as in Applications/Sublime Text/ for command names such as open_dir but I still can't find the code of the commands that the JSON script is referencing.

Is there a way to find and view the commands that the JSON script is referencing?

EDIT: Thanks and apologies to those who commented before I made this edit. I've changed the title and the question text pretty heavily to try to be clearer since the post got put on hold.

Can you put some code here? (i.e `your-json-file.json` and `your-python.py`. — Frank AK, Nov 29 '17 at 05:44
A JSON file is not executable by itself, so unless you're using something else to interpret the JSON file, and do something with the contents, no. — roelofs, Nov 29 '17 at 05:44
You could write a python function that parses the JSON object and then creates an subprocess based on the value of a key. — MyCah, Nov 29 '17 at 05:50
Trying to have JSON call Python is like trying to have your shopping list load your groceries into your car; JSON doesn't *do* things. — user2357112 supports Monica, Nov 29 '17 at 05:50
@FrankAK I edited my main post to include relevant information about what exactly I'm trying to do. — colossatr0n, Nov 29 '17 at 06:59
Sublime probably loads all builtin functions, then calls something like `eval("open_dir")` — OneCricketeer, Nov 29 '17 at 07:10

JSON is parsed, not interpreted. Plus they are not executable, much like a plain text file.

Therefore, you use python as normal to run a subprocess, but from a parsed value rather than a hard coded command

Its a bit unclear from your question what your end goal really is. You should provide some examples.

If you are looking to parse JSON data, extracted from a file, and execute in the terminal, then using the subprocess is likely the way to go.

I've explained the reasoning behind my question with the edit to my main post. Hopefully that helps clarify. – colossatr0n Nov 29 '17 at 06:56
