If you've ever wanted to tweak how Sublime Text works or add a specific feature that isn't built-in, creating your own package is the way to go. The good news is, it’s not as complicated as it might sound — especially for simple tasks like adding custom commands or snippets.

What You Need Before Starting

Before diving into writing your package, make sure you're familiar with:

• Python basics – Sublime packages are mostly written in Python.
• Sublime's API docs – They’re your best friend when figuring out what functions and classes are available.
• Your goal – Do you want to create a new command, modify syntax highlighting, or something else?

You don’t need any extra tools beyond Sublime Text itself. Just open the console (`Ctrl ``) and start exploring.

Where to Put Your Package Files

Sublime looks for packages in a specific folder, which you can access via Preferences > Browse Packages.... Inside this directory, create a new folder for your package — for example, MyCustomTools.

Anything placed here will be loaded automatically on startup. That means if there’s a Python file with a class that extends Sublime’s base classes (like sublime_plugin.Command), it’ll show up in the command palette once saved.

How to Create a Custom Command

Let’s say you want to create a command that inserts the current date into your file.

1. Inside your package folder, create a .py file (e.g., insert_date.py).
2. Define a class that inherits from sublime_plugin.TextCommand.
3. Add a method called run() that takes self and edit as arguments.
4. Use self.view.insert(edit, position, content) to insert text.

Here’s a basic version:

import sublime
import sublime_plugin
from datetime import datetime

class InsertDateCommand(sublime_plugin.TextCommand):
    def run(self, edit):
        today = datetime.now().strftime("%Y-%m-%d")
        self.view.run_command("insert_snippet", {"contents": today})

Once saved, you can trigger this command by opening the Command Palette (Ctrl Shift P) and typing “Insert Date”.

Adding Keyboard Shortcuts and Menus

After writing a command, you probably want to bind it to a key or add it to the context menu.

To assign a keyboard shortcut:

• Go to Preferences > Key Bindings
• Add an entry like: { "keys": ["ctrl alt d"], "command": "insert_date" }

For right-click menu integration:

• Create a file named Context.sublime-menu inside your package folder
• Add JSON defining where the command appears, e.g.:

[
  {
    "command": "insert_date",
    "caption": "Insert Current Date"
  }
]

This makes your command accessible without switching to the command palette.

That’s basically all you need to get started building your own Sublime Text package. It’s not super complex, but there are enough moving parts that small mistakes — like a typo in the class name or forgetting to restart Sublime after changes — can trip you up. Keep it simple at first, test often, and refer back to the official documentation when things don’t work as expected.
