Compiler Guide

RUDRA ships two front-end commands: rudrac, the compiler, and rudra, the project driver.

rudrac

Command	Effect
`rudrac file.rux`	Compile to a native binary
`rudrac file.rux -o name`	Compile and set the output name
`rudrac file.rux --run`	Compile and run immediately
`rudrac --version`	Show the compiler version

rudrac hello.rux --run
rudrac hello.rux -o hello

Command	Effect
`rudra new <name>`	Create a new project
`rudra run [file]`	Compile and run (default: src/main.rux)
`rudra build [file]`	Compile into a native binary
`rudra check [file]`	Type-check without building
`rudra clean`	Clean the build folder
`rudra doctor`	Run an environment check
`rudra version`	Show the version

The compiler reports type errors before building. For example, calling len on an array reports a type error, because len operates on strings.
