Detailed Description

Command-line interface and entry point for the Fun interpreter.

Main entry point for the Fun language interpreter. Builds a CLI that runs a script file if provided; otherwise starts the REPL when compiled with FUN_WITH_REPL enabled.

Definition in file fun.c.

Function Documentation

◆ main()

int main	(	int	argc,
		char **	argv )

Program entry point for the Fun interpreter.

Parses CLI options, compiles and runs a script file if provided, or launches the REPL when enabled and no script is given. Exposes script arguments to the program via FUN_ARGC/FUN_ARGV_i/FUN_ARGS environment variables.

Parameters

argc	Argument count.
argv	Argument vector; argv[0] is used to expose FUN_EXECUTABLE.

Returns: Process exit code, typically taken from the VM after execution.

Definition at line 76 of file fun.c.

◆ print_usage()

void print_usage ( const char * prog )

static

Print command-line usage instructions to stdout.

The usage varies depending on whether the binary was built with FUN_WITH_REPL enabled.
