Raven Language
Raven is a statically typed systems language with a small runtime. This extension adds VS Code support for .rv files (Raven v2 syntax): highlighting, snippets, and a few editor conveniences.
Docs: raven documentation · Language & compiler: GitHub
Features
- Syntax highlighting for Raven v2 source, including PascalCase types, traits, generics,
match arms, ${...} string interpolation, c"..." and """...""" strings, ranges, and extern blocks
- Snippets for common patterns (bindings, functions, control flow, structs, enums, traits, impls,
match, closures, defer, imports, main, printing)
- Comments & brackets: line comments (
//), block comments, sensible bracket/indent behavior for .rv files
- Run Raven File: opens a terminal and runs the current file with the
raven CLI (see below)
- Hovers & completions for built-in functions and common keywords
This extension does not embed the compiler. For full type-checking and navigation, use the raven CLI or your usual workflow outside the editor.
Requirements
The Run Raven File command expects a raven executable on your system PATH.
- Install a release build, or build from source using the instructions in the main repository.
If raven is not installed, you still get highlighting and snippets; only run-in-terminal will fail until the CLI is available.
Using Run Raven File
- Open a
.rv file (or pick one in the Explorer).
- Either:
- Command Palette (
Ctrl+Shift+P / Cmd+Shift+P) → Raven: Run Raven File, or
- Right-click the file in the editor or Explorer → Run Raven File.
The extension compiles the file with raven build "<path>" -o "<output>" and,
on a successful build, runs the produced native binary in a new terminal. A
compile error is shown as a notification with the compiler's message.
