A Python library that parses strings using a specification based on the Python format() syntax, effectively the inverse of str.format(). It provides parse(), search(), findall(), and with_pattern() functions with compiled pattern support.

Use cases

• parse strings using format spec syntax
• extract values from log lines
• search text for pattern matches
• find all occurrences of a pattern in a string
• convert parsed fields to typed values
• parse fixed-format text files

When to choose

• you want to reverse str.format() to extract data from strings
• you need simple typed string parsing without regex complexity
• you're parsing structured log lines or templated text

When to avoid

• you need full regex power like lookaheads or alternation
• you're parsing complex grammars or nested structures
• you need high-performance bulk parsing
