Blorp by Example

Hello, Blorp

Start with the program entry point, a line of output, and the run command.

Main

A runnable file defines main as the entry point. args is a List[String] containing command-line arguments.

entry.brp

func main(args: List[String]) -> Void:
    print("ready")

Printing

print writes a trailing newline. puts writes without adding one, and eprintln writes to stderr.

output.brp

print("one line")
puts("prompt> ")
eprintln("warning")

Running A File

Use blorp run file.brp to compile and run one source file.

terminal

blorp run hello.brp

Exit Codes

A main returning Void exits successfully and returns an exit code of 0. A main returning Int uses the final Int expression as the process exit code.

exit.brp

func main(args: List[String]) -> Int:
    print("ok")
    0

Example

hello.brp

func main(args: List[String]) -> Void:
	print("Hello, world!")

Exit-code Version

hello-exit.brp

func main(args: List[String]) -> Int:
	print("Hello, world!")
	0

Try It

terminal

blorp run hello.brp
