emplace

Modern and easy way to handle placeholders.

This package allows you to define text placeholders and process them dynamically. It's like str.format(), but gives you much more flexibility.

Features

• Regular Expressions to find placeholders.
• Custom delimiters (%var%, {var}, ${var} etc.).
• Modern API using asyncio and decorators.
• Nested placeholders ({greet_{name}}).
• Type safety using annotations.
• No additional dependencies.

Usage

from emplace import Formatter, placeholder

class MyFormatter(Formatter):
    @placeholder(r"upper_(?P<text>.*)")
    def upper_ph(self, text: str) -> str:
        return text.upper()
    
formatter = MyFormatter()
result = await formatter.format("Hello, {upper_world}!")
print(result) # Hello, WORLD!
