Tutorial: Using the clike REPL

The clike-repl executable lets you experiment interactively with the small C-like language that targets the Pscal virtual machine.

Build the REPL

From the repository root run:

cmake -B build
cmake --build build --target clike-repl

This creates build/bin/clike-repl.

Start an interactive session

Launch the REPL:

build/bin/clike-repl

Each line you enter is wrapped in a minimal int main() function and executed immediately.

Example usage

$ build/bin/clike-repl
clike> printf("hello world\n");
hello world
clike> 2 + 2;
4
clike> int a; a = 100; int b; b = 33; printf("%d\n", a + b);
133
clike> 
clike> :quit

Use :quit to exit the session.
