tinyexec
Effection compatible wrapper around tinyexec package.
To run a process, use the x
function:
import { x } from "@effection-contrib/tinyexec";
import { each, main } from "effection";
await main(function* () {
let proc = yield* x("echo", ["Hello, World"]);
for (let line of yield* each(proc.lines)) {
console.log(line);
yield* each.next();
}
});
// => prints "Hello, World"
The process will be automatically destroyed whenever it passes out of scope. For
example, the following shows the output of the top
command for five seconds
before exiting.
import { x } from "@effection-contrib/tinyexec";
import { each, main, sleep, spawn } from "effection";
await main(function* () {
yield* spawn(function* () {
let proc = yield* x("top");
for (let line of yield* each(proc.lines)) {
console.log(line);
yield* each.next();
}
});
yield* sleep(5000);
});

interface TinyProcess extends Operation<Output> {
- lines: Stream<string, void>;
A stream of lines coming from both stdin and stdout. The stream will terminate when stdout and stderr are closed which usually corresponds to the process ending.
- kill(signal?: KillSignal): Operation<void>;
