Process

The @std/process module runs external commands and captures their output.

import process from "@std/process"

let result = process.run("echo", ["Hello"])

println(result.stdout)
println(result.stderr)
println(result.exit)

process.run

Runs a command with optional arguments.

Arguments:

Name	Type	Default	Description
cmd	string	none	Command to execute.
args	[]any	[]	Command arguments.

Returns: a result struct.

Result fields:

Name	Type	Description
stdout	string	Captured standard output.
stderr	string	Captured standard error.
exit	int	Exit code.

import process from "@std/process"

let result = process.run("git", ["--version"])

if result.exit == 0 {
    println(result.stdout)
} else {
    println(result.stderr)
}

Checking Command Results

Use the exit field to check whether the command succeeded.

import process from "@std/process"

let result = process.run("nubo", ["--version"])

if result.exit != 0 {
    println("Command failed:")
    println(result.stderr)
}

Function Implementation Style

fn printCommand(command: string, args: []string) void {
    let result = process.run(command, args)

    println(result.stdout)
}
