Funcy Language Support for VS Code
Syntax highlighting for the Funcy programming language.
Features
- Syntax highlighting for
.fu files
- Support for all Funcy language constructs:
- Variables (
@name)
- Functions (
=>, * for recursion)
- Module exports (
#module@export)
- Event subscriptions (
%event_name)
- Event triggers (
&event_name)
- Await operator (
$)
- Comments (
//)
- Built-in functions (if, exists, log, throw, capture, etc.)
- Built-in modules (Array, Map, String, IO)
- Type annotations (int, string, bool, array, map, func, any)
- Operators and literals
Installation
From Source
Copy the vscode-funcy directory to your VS Code extensions folder:
- macOS/Linux:
~/.vscode/extensions/
- Windows:
%USERPROFILE%\.vscode\extensions\
Restart VS Code
From VSIX (if packaged)
code --install-extension funcy-lang-0.1.0.vsix
Usage
Open any .fu file and syntax highlighting will be automatically applied.
Example
// Factorial with recursion
@factorial n => if(n = 0, 1, n * *(n - 1));
// Array operations
@numbers [1, 2, 3, 4, 5];
@double n => n * 2;
@doubled map(numbers, double);
// Module export
#math@square x => x * x;
// Type annotations
@add x:int, y:int => x + y;
// Async operations
@result $IO.get("https://api.example.com/data");
