vroom

A simple script to build the smallest Vlang executable possible. Please note that this may break executables or make cryptic errors. Also, this is a short PoC about executable optimization for V and it was not designed for production use.

Requirements

This script requires the following:

• Vlang compiler
• Clang
• Strip utility

Usage

$ vroom [path/to/file.v or path/to/dir] -o [output_executable]

Example

$ vroom ./example.v -o example.elf
