Can ChatGPT write the Python async message queue codes from the previous posts?

Marton Trencseni - Sun 05 March 2023 • Tagged with python, async, message, queue, chatgpt

I try to get ChatGPT to write the codes in the previous posts. It's able to write the basic message queue skeleton, but cannot implement more complicated features such as delivery semantics with caching.

rxe: literate and composable regular expressions

Marton Trencseni - Sat 02 March 2019 • Tagged with python

rxe is a thin wrapper around Python's re module. The various rxe functions are wrappers around corresponding re patterns. For example, rxe.digit().one_or_more('a').whitespace() corresponds to \da+\s. Because rxe uses parentheses but wants to avoid unnamed groups, the internal (equivalent) representation is actually \d(?:a)+\s. This pattern can always be retrieved with get_pattern().
