seqpat

seqpat is a Python library designed for flexible and efficient sequence pattern matching, primarily aimed at converting microformats from various command-line tools into JSON Line format.

The motivation behind this project was the idea: "Wouldn't it be great if we could perform operations on a sequence of strings (i.e., lines of text like in a text file) in the same way we use regular expressions on individual strings (i.e., a sequence of characters)?"

Features

• Pattern Matching: Match sequences of strings using customizable patterns.
• Sequence Handling: Process and parse structured text data efficiently.
• Customizable Replacements: Use pattern-based substitutions to transform the input as needed.

Installation

You can install seqpat using pip:

pip install seqpat

Patterns/Utility Functions

The core of seqpat is its ability to define and use flexible patterns for text matching. It provides:

• R: A pattern that matches regular expressions.
• gsub: A function for global substitution based on patterns.
• split_by: A function to split a sequence of strings by a delimiter pattern.

For detailed usage, please refer to the Docstrings, and for examples, see the examples directory.
