Documentation
Documentation is available on jsr.io

Usage
import { args, execPath, cwd, chdir, stdout, stdin } from "@bearz/process";
console.log(args); // the args passed to current process.
console.log(execPath()); // path to executable for the current process.
console.log(cwd()); // the current working directory.
chdir(".."); // changes the current working directory.
console.log(cwd()); // updated current working directory.
stdout.writeSync(new TextEncoder().encode("hello world\n"));
// read stdin
const buffer = new Uint8Array(1024);
const bytesRead = stdin.readSync(buffer);
if (bytesRead && bytesRead.length > 0) {
// write it back out
stdout.writeSync(buffer.subarray(0, bytesRead))
}
Constants
Runtime
- args - Array of arguments passed to the current process.
- pid - The id of the current process.
- stdin - The standard input stream which is a stream reader that uses Uint8Array.
- stdout - The standard output stream which is a stream writer that uses Uint8Array.
- stderr - The standard error stream which is a stream writer that uses Uint8Array.
Functions
- cwd - Gets the current working directory.
- chdir - Changes the current working directory.
- execPath - Gets the path of the executable that spawned the current process.
- exit - Exits the current process with the exit code provided. If the exit code is not set, its zero.
- popd - Pops the last directory and returns it while changing the current directory to the last one from history.
- pushd - Pushs a path to chdir and records the path in history.
