Visual Studio Code
This page describes how to set-up Visual Studio Code (VSCode) for VScript purposes.
Usage
Squirrel
Click on the Extensions button in VSCode. This is represented as a icon of building blocks, usually on the left side of the window.
Search for "Squirrel" in the search bar. Install the following extensions:
- Squirrel Language Supports (by marcinbar)
- Squirrel Language Linter (by marcinbar)
Restart VSCode. Now the language is ready for use in the editor!
Autocomplete
For 
Team Fortress 2, auto-completion of the game's built-in script functions and constants is also available.
To install, press Ctrl + Shift + P in VSCode.
Search for "Configure User Snippets" and click on the command, then search for "squirrel" and click on it. You should have a "squirrel.json" window open at this point.
Replace the contents of this window with the text here.
Tip:Press the Raw button on the Github page and then press Ctrl + A to select all of the text and Ctrl + C to copy everything. You can now paste this directly into the VSCode document.Save the file, and now VSCode will provide autocomplete for your scripts!
