PEP Tooltip

Add a tooltip alongside PEP numbers in discuss.python.org messages.

Members of the Python community often refer to Python Enhancement Proposal (PEPs) using only their number, sometimes without a link or additional context. To fully grasp what's been talked about, a quick check on peps.python.org is often necessary: that means opening a new tab/window, resulting in a small defocus and loss of time. To make things smoother, this extension scans all messages on discuss.python.org and add a ℹ️ emoji next to each occurrence of of the "PEP XXX" pattern. On hover, a tooltip appears displaying key information about the PEP (retrieved from peps.python.org official API). To keep the popup digest, only a subset of PEP information fields are displayed; these may change based of feedback! Messages loaded when scrolling one the page are detected and processed too (but not just posted / edited messages, at the moment). This extension is open-source (hosted at github.com/loic-simon/pep-tooltip) ; it only requires the permission to read and update content on discuss.python.org. It does not collect any form of data.
