SmartJoiner

SmartJoiner, created by Khalid Sulaiman Al-Mulaify, is a Python library that enhances the traditional join function by adding powerful and flexible features. Whether you're building dynamic outputs, enhancing readability, or working with complex lists, SmartJoiner provides the tools to handle it efficiently.

Features

✔ Conditional joining
✔ Customizable padding
✔ Indexed join
✔ Mixed separators
✔ Transform function
✔ Recursive joining
✔ Localized join
✔ Dynamic separator function

Installation

Install SmartJoiner via pip:

pip install smartjoiner

Usage

Import the SmartJoiner class and use its join method.

from smartjoiner import SmartJoiner

Feature Details & Examples

1. Conditional Joining

Join only elements that satisfy a given condition, such as filtering by string length.

result = SmartJoiner.join(
    ["orange", "banana", "cherry", "grapes", "melon"],
    separator=", ",
    condition=lambda s: len(s) == 6
)
print(result)
# Output: "orange, cherry"

2. Customizable Padding

Add padding to each element, such as enclosing each string in quotes or wrapping it with special characters.

result = SmartJoiner.join(
    ["apple", "banana", "cherry"],
    separator=", ",
    pad="'"
)
print(result)
# Output: "'apple', 'banana', 'cherry'"

3. Indexed Join

Include the index of each element in the joined string for tracking or formatting purposes.

result = SmartJoiner.join(
    ["apple", "banana", "cherry"],
    separator=" | ",
    with_index=True
)
print(result)
# Output: "0: apple | 1: banana | 2: cherry"

4. Mixed Separators

Use different separators between elements based on position or other criteria.

result = SmartJoiner.join(
    ["apple", "banana", "cherry"],
    separators=[" - ", " ~ "]
)
print(result)
# Output: "apple - banana ~ cherry"

5. Transform Function

Apply a transformation to each element before joining, such as uppercasing, reversing, or formatting strings dynamically.

result = SmartJoiner.join(
    ["apple", "banana", "cherry"],
    separator=", ",
    transform=str.upper
)
print(result)
# Output: "APPLE, BANANA, CHERRY"

6. Recursive Joining

Automatically flatten nested lists and join all elements into a single string.

result = SmartJoiner.join(
    ["apple", ["banana", "cherry"], "date"],
    separator=" - "
)
print(result)
# Output: "apple - banana - cherry - date"

7. Localized Join

Add a natural language conjunction like "and" or "or" before the last element for better readability.

Example 1: Using "and" (default)

result = SmartJoiner.join(
    ["apple", "banana", "cherry"],
    separator=", ",
    localized=True
)
print(result)
# Output: "apple, banana, and cherry"

Example 2: Using "or"

result = SmartJoiner.join(
    ["apple", "banana", "cherry"],
    separator=", ",
    localized=True,
    localized_word="or"
)
print(result)
# Output: "apple, banana, or cherry"

8. Dynamic Separator

Define a custom separator function to decide the separator based on the element's index or value.

result = SmartJoiner.join(
    ["apple", "banana", "cherry"],
    separator_function=lambda i, _: " - " if i % 2 == 0 else " ~ "
)
print(result)
# Output: "apple - banana ~ cherry"
