Mojo module

format

String formatting utilities for Mojo.

This module provides string formatting functionality similar to Python's str.format() method. It implements curly brace {} based string formatting with support for positional arguments, named arguments, format specifiers and conversion flags.

Key Features:

Curly brace {} based string formatting
Support for positional and named arguments
Format specifiers for controlling output format
Conversion flags for str() and repr() conversions
Automatic and manual argument indexing
Fill, align, sign and other formatting options

Example:

from collections.string import String

# Basic formatting
var s1 = "Hello {0}!".format("World")  # Hello World!

# Multiple arguments
var s2 = "{0} plus {1} equals {2}".format(1, 2, 3)  # 1 plus 2 equals 3

# Format specifiers
var s3 = "{:>10}".format("test")  # '      test'

# Conversion flags
var s4 = "{!r}".format("test")  # "'test'"
from collections.string import String

# Basic formatting
var s1 = "Hello {0}!".format("World")  # Hello World!

# Multiple arguments
var s2 = "{0} plus {1} equals {2}".format(1, 2, 3)  # 1 plus 2 equals 3

# Format specifiers
var s3 = "{:>10}".format("test")  # '      test'

# Conversion flags
var s4 = "{!r}".format("test")  # "'test'"

Note:

This is an internal implementation module. Users should use the format() methods provided by the String and StringSlice types rather than using these utilities directly.
