lrparse 0.1.3

Left/right substring extraction

lrparse

lrparse is a tiny, fast Python library written in C for extracting substrings between left and right delimiters.

It provides two functions:

• lr() – returns the first substring between delimiters.
• lrr() – returns all substrings between delimiters.

Installation

pip install lrparse

Usage

import lrparse

# lr() → first match between delimiters
print(lrparse.lr("pre[mid]post", "[", "]"))
# ['mid']

# lrr() → all matches between delimiters
print(lrparse.lrr("<a><b>c", "<", ">"))
# ['a', 'b']

# If delimiters don't exist, you get an empty list
print(lrparse.lr("hello world", "{", "}"))
# []

# If both delimiters are empty, the whole string is returned
print(lrparse.lr("abc", "", ""))
# ['abc']
