Are you familiar with gemtext, the markup format? Please describe it.

1. Claude

Yes, I'm familiar with gemtext, the markup format. Gemtext is a lightweight markup language designed for use in the Gemini protocol, which is an alternative to HTTP for serving content on the internet.

A tiny introduction to regular expressions in Python

Import the module: import re
Basic match: re.search(r'cat', 'concatenate') → finds 'cat' anywhere.
Full match: re.fullmatch(r'cat', 'cat') → must match the entire string.
Find all: re.findall(r'\d+', 'a1b22c333') → ['1', '22', '333']
Replace: re.sub(r'\s+', ' ', 'too many spaces') → 'too many spaces'
Character classes:

\d digits, \w word chars, \s whitespace
