tag-formatter

Tag-formatter is a Python Package designed to format strings that based on user-input.
For example, tag-formatter can parse something such as:

Hello there, {user}!

Into something like:

Hello there, John!

Installation

You can install tag-formatter using pip.

pip install tag-formatter

Features

• Highly customizable
  • Uses regex delimiters that you can set.
• Uses a parser rather than things like str.format
  • Because this was meant for user input, str.format wouldn't work (invalid tags mean KeyErrors)
  • str.replace on the other hand, would be too tedious and limited.
• Argument parsing for tags
  • Basic and function-based converters
  • Default values for arguments

Example

You can find more examples in the examples folder.

import random
import tagformatter

class User:
    name = 'John'
    age = 21

parser = tagformatter.Parser()

@parser.tag("user")
def user_tag(env):
    return env.user.name

@user_tag.tag("age")
def user_age_tag(env):
    return env.user.age

@parser.tag("random", alias="rng")
def rng_tag(env, low: int = 1, high: int = 10):
    return random.randint(low, high)

print(parser.parse("{user} is {user.age} years old. Random number: {random:1, 20}", 
      env={"user": User()}))
