SQF Language Support for VS Code

Syntax highlighting, real-time diagnostics, IntelliSense, hover docs, wiki lookup, snippets, formatting, and build integration for Arma SQF and SQ# (SQF Sharp).

Powered by the SQ# engine — a .NET reimplementation of Arma 3's SQF scripting language.

Features

Feature	Description
Syntax highlighting	Full TextMate grammars — 2,630 Arma commands + SQ# keywords
Real-time diagnostics	Red wavy underlines as you type — no save needed
IntelliSense autocomplete	All 2,630 commands + local variables + keywords
Hover documentation	~120 commands with signatures and descriptions
Wiki lookup	`Ctrl+K Ctrl+W` → open `community.bistudio.com/wiki/<command>`
Go to definition	`Ctrl+Click` on `#include "file.sqf"` to open it
Code snippets	25 snippets: `if`, `while`, `for`, `switch`, `try`, `private`, `params`, etc.
Document formatting	`Shift+Alt+F` — auto-indent based on `{}` blocks
SQ# CLI integration	Compile, run, lex, parse from command palette
Problem matcher	Errors appear in Problems panel (`Ctrl+Shift+M`)
Bundled CLI	Zero-install — self-contained SQ# binaries for win/linux/mac
Preprocessor highlighting	`#include`, `#define`, `#ifdef` (Arma SQF mode)
Bracket matching	`{}`, `[]`, `()` auto-close and match
Code folding	`//region` markers + indentation-based
Status bar toggle	Click to switch between Arma SQF and SQ# highlighting
Task integration	`tasks.json` compile and run tasks

Language Modes

Both modes auto-detect .sqf files and run SQ# diagnostics on all of them. The difference is syntax highlighting:

Mode	File Association	Highlighting
Arma SQF	`.sqf` (default)	All 2,630 Arma commands + preprocessor
SQ#	Manual switch via status bar or `Ctrl+Shift+P`	SQ# keywords + concurrency commands

Click the status bar indicator (Arma SQF / SQ#) to toggle highlighting mode. Diagnostics, autocomplete, hover, and all other features work in both modes.

SQ# CLI Integration

No setup required — self-contained SQ# binaries bundled for Windows, Linux, and macOS.

Override: set sqf.sqsharpCliPath to a custom SQ# CLI path.
