Home Standard Library - Session Complete

Date: 2025-10-22 Status: ✅STANDARD LIBRARY COMPLETE

🎯 Session Objectives

Complete the remaining standard library features to make Home producthome-ready for real-world applications, then create a comprehensive roadmap for competing with PHP, TypeScript, and Python.

✅ Features Implemented

1. Date/Time Utilities (src/stdlib/datetime.zig)

Lines: 430

Features:

• DateTime struct with Unix timestamp and nanoseconds
• Current time: DateTime.now()
• Create from components: fromComponents(year, month, day, hour, minute, second)
• Create from timestamp: fromTimestamp(seconds)
• Date arithmetic:
  • addSeconds(), addMinutes(), addHours(), addDays()
  • diffSeconds(), diffMinutes(), diffHours(), diffDays()
• Formatting:
  • ISO 8601: formatISO() → "2025-10-22T14:30:00Z"
  • Custom format: format(allocator, "%Y-%m-%d %H:%M:%S")
• Duration type:
  • fromSeconds(), fromMinutes(), fromHours(), fromDays(), fromMilliseconds()
  • add(), subtract() operations
• Timer: Measure elapsed time
  • Timer.start(), elapsed(), elapsedMillis(), reset()
• Parsing: parseISO() for ISO 8601 strings
• Time zones: UTC, EST, PST, CET, JST offsets
• Utility functions: sleep(), isLeapYear(), getDaysInMonth()

Example Usage:

let now = DateTime.now();
let tomorrow = now.addDays(1);
let formatted = now.formatISO(allocator); // "2025-10-22T14:30:00Z"

let custom = now.format(allocator, "%Y-%m-%d"); // "2025-10-22"

let hashed = Password.hash(allocator, "mypassword", salt);
let valid = Password.verify("mypassword", salt, hashed);

Example Usage:

// Simple execution
let result = exec(allocator, &[_][]const u8{"ls", "-la"});
std.debug.print("Output: {s}\n", .{result.stdout});

// With ProcessBuilder
let result = ProcessBuilder.init(allocator)
    .command("git")
    .args(&[_][]const u8{"log", "--oneline"})

• Typed arguments: String, Int, Float, Bool, StringList
• Short flags: -f
• Long flags: --flag
• Required/optional arguments
• Default values
• Auto-generated help (-h, --help)
• Positional arguments

Example:

let parser = ArgParser.init(allocator, "myapp", "My awesome application");

// Add arguments
parser.addString("input", 'i', "input", true, null, "Input file path");
parser.addInt("port", 'p', "port", false, "8080", "Server port");
parser.addBool("verbose", 'v', "verbose", "Enable verbose output");

// Parse
parser.parse(argv);

// Get values
let input = parser.getString("input").?;
let port = parser.getInt("port") orelse 8080;
let verbose = parser.getBool("verbose");
let positional = parser.getPositional();

Help output:

My awesome application

USAGE:
  myapp [OPTIONS]

OPTIONS:
  -h, --help              Show this help message
  -i, --input             Input file path (required)
  -p, --port              Server port [default: 8080]
  -v, --verbose           Enable verbose output

SimpleArgs (Quick parsing)

let args = SimpleArgs.init(allocator);
args.parse(argv);

let value = args.get("flag");
let has_flag = args.has("verbose");
let positional = args.getPositional();

Environment Variables

let value = Env.get(allocator, "HOME");
let fallback = Env.getOrDefault(allocator, "PORT", "8080");
Env.set("MY_VAR", "value");
