Introduction
V is a statically typed compiled programming language designed for building maintainable software. It compiles to native code via a C backend and can compile itself in under one second with zero external dependencies. V aims to combine the best ideas from Go's simplicity with performance close to C.
What V Does
- Compiles to optimized native code through a C intermediate step
- Provides autofree memory management without a garbage collector
- Supports automatic C-to-V source code translation
- Offers built-in concurrency with coroutines and channels
- Includes a cross-platform UI library and package manager
Architecture Overview
V's compiler is written in V itself and translates V source files to C, which is then compiled by any standard C compiler. The autofree engine tracks allocations and inserts deallocation calls at compile time. The standard library is self-contained with no OS-level dependencies beyond libc, enabling reproducible builds.
Self-Hosting & Configuration
- Clone and bootstrap from GitHub with
make(Linux/macOS) ormake.bat(Windows) - Install packages via
v install <package>from the VPM registry - Configure build flags in
v.modper project - Cross-compile to other OS targets with
v -os windows . - Use
v fmtfor automatic code formatting
Key Features
- Sub-second full-project compilation speed
- No null, no undefined behavior, no global state by default
- Hot code reloading for rapid iteration
- Built-in testing framework via
v test - Generics, interfaces, and sum types without complexity overhead
Comparison with Similar Tools
- Go — V has a similar syntax but adds generics natively and avoids a GC by default
- Rust — Rust offers stronger safety guarantees via the borrow checker but has a steeper learning curve
- Zig — Zig targets lower-level systems work while V aims for higher-level productivity
- D — D is more feature-rich but V prioritizes minimalism and fast compile times
- Nim — Nim also compiles via C but uses a GC; V's autofree avoids that
FAQ
Q: Does V require a garbage collector? A: No. V uses an autofree system that inserts deallocations at compile time. An optional GC is available if needed.
Q: Can I use C libraries from V?
A: Yes. V supports direct C interop, and the v translate tool can convert C headers to V bindings.
Q: Is V production-ready? A: V is under active development. It is usable for personal projects and CLI tools, though some features are still stabilizing.
Q: What platforms does V support? A: V runs on Linux, macOS, Windows, FreeBSD, and can cross-compile to Android and WebAssembly.
