ChadScript

Appearance

process ​

Process utilities, command-line arguments, and environment access. Maps to POSIX process APIs.

Properties ​

process.argv ​

typescript
process.argv    // string[] — command line arguments

argv[0] is the first user argument (not the program name, unlike C).

typescript
const filename = process.argv[0];
console.log(filename);

process.platform ​

typescript
process.platform    // "linux" or "darwin"

process.arch ​

typescript
process.arch    // "x64", "arm64", etc.

process.pid / process.ppid ​

typescript
process.pid     // number — current process ID
process.ppid    // number — parent process ID

process.env ​

typescript
process.env.HOME        // string — environment variable via getenv()
process.env.PATH
process.env.USER

.env auto-loading ​

Every compiled binary automatically loads a .env file from the working directory at startup (before any user code runs). If no .env file exists, this is a silent no-op.

bash
# .env
DATABASE_URL=postgres://localhost/mydb
API_KEY="sk-abc123"
# Comments are ignored
typescript
const dbUrl = process.env.DATABASE_URL;  // "postgres://localhost/mydb"

Real environment variables always take precedence over .env values — .env only fills in missing vars. Quoted values ("..." or '...') are unquoted automatically.

process.execPath ​

typescript
process.execPath    // string — path to the current executable

process.argv0 ​

typescript
process.argv0    // string — the original argv[0] (program name)

process.version ​

typescript
process.version    // string — ChadScript version

Methods ​

process.exit(code?) ​

typescript
process.exit(0);    // exit successfully
process.exit(1);    // exit with error
process.exit();     // exit with code 0

process.cwd() ​

typescript
const dir = process.cwd();    // string — current working directory

process.chdir(path) ​

typescript
process.chdir("/tmp");

process.uptime() ​

typescript
const seconds = process.uptime();    // number — seconds since program start

process.kill(pid, signal) ​

typescript
process.kill(1234, 9);    // send signal to process

process.abort() ​

typescript
process.abort();    // immediately terminate with SIGABRT

process.getuid() / process.getgid() / process.geteuid() / process.getegid() ​

typescript
const uid = process.getuid();
const gid = process.getgid();
const euid = process.geteuid();
const egid = process.getegid();

process.stdout.write(str) / process.stderr.write(str) ​

Write without a trailing newline:

typescript
process.stdout.write("no newline");
process.stderr.write("error output");
