11.9. lpipe macro

The LPIPE module provides the lpipe macro for passing multiple block arguments to a single function call. While <| handles the first block argument, lpipe adds subsequent blocks on following lines.

All functions and symbols are in “lpipe” module, use require to get access to it.

require daslib/lpipe

Example:

require daslib/lpipe

    def take2(a, b : block) {
        invoke(a)
        invoke(b)
    }

    [export]
    def main() {
        take2() {
            print("first\n")
        }
        lpipe() {
            print("second\n")
        }
    }
    // output:
    // first
    // second

11.9.1. Call macros

lpipe

Implements lpipe, allowing blocks to pipe the previous line’s call.
