Standard Library: Process (std/process.zc)

The process module allows you to spawn and interact with child processes.

Usage

import "std/process.zc"

fn main() {
    let output = Command::new("echo")
        .arg("hello")
        .output();
        
    if (output.exit_code == 0) {
        output.stdout.print();
        // Or access raw C string: output.stdout.c_str()
    }
}

Structs

Command

A builder for spawning a process.

struct Command {
    program: String;
    args: Vec<String>;
}

Methods

Method	Signature	Description
new	Command::new(program: char*) -> Command	Creates a new Command for the given program.
arg	arg(self, arg: char*) -> Command*	Adds an argument to the command. Returns the command pointer for chaining.
output	output(self) -> Output	Executes the command as a child process, waiting for it to finish and collecting all of its stdout.
status	status(self) -> int	Executes the command as a child process and returns the exit status code. Does not capture output (output goes to stdout/stderr).

Output

The output of a finished process.

struct Output {
    stdout: String;
    exit_code: int;
}

Methods

Output implements Drop to automatically free the captured stdout string.
