v

v [run] [-prod] [options] file

v is the compiler for the V programming language, a statically typed systems language designed for simplicity and fast compilation. It compiles V source code to native machine code via C, achieving near-instant build times even for large projects.The compiler includes a built-in code formatter, test runner, REPL, and package manager. V emphasizes memory safety through features like no null pointers, immutable variables by default, and optional garbage collection. It provides seamless C interoperability, allowing direct calls to C libraries without bindings.Production builds with the -prod flag enable additional optimizations. The compiler can also generate C source code for portability to platforms without a V compiler available.

run

Compile the source file(s) and immediately execute the resulting binary.

Format source files using the canonical V style.

Compile and run _test.v files in the given directory or module.

Start the interactive Read-Eval-Print Loop.

Subcommands for module scaffolding and dependency management.

Output binary filename.

Enable production optimizations (slower compile, faster binary).

Back-end C compiler to use (e.g. clang, gcc, tcc).

Include debug information in the output.

Append extra flags for the C compiler or linker.

Build a shared library instead of an executable.

Enable the experimental auto-free memory management mode.

Choose a garbage-collector mode (e.g. boehm, none).

Print detailed statistics (especially useful with v test).

Report per-phase compilation times.

Skip code generation for unused functions (faster builds).

Young language. Ecosystem growing. V-specific.

V was created by Alexander Medvednikov as a simple, fast, and safe systems programming language.
