Forked from /info/en/?search=User:Ajbura/anrfc-lister.js. A big thanks to the original author, Ajbura.



HOW TO USE:

- go to a talk page

- click More -> ANRFC Lister

- there will now be "List on ANRFC" links next to each section. click one

- fill out the form

- press "Submit"

- the script will add a listing to WP:ANRFC for you :)



SKINS IT WORKS IN:

- vector

- vector-2022

- timeless

- monobook

- modern



SKINS IT DOESNT WORK IN:

- minerva



CHANGES BY NOVEM LINGUAE:

- Linted code. Added comments. Refactored.

- Works on testwiki now (gives a local WP:ANRFC link instead of an enwiki WP:ANRFC link).

- Fixed bug where the script was always in an endless loop

- Fixed bug where the RFC would always get placed at the bottom of the page, not in its proper section

- Fixed bug where section heading (the # part of the wikilink) was not getting added to WP:ANRFC

- Fixed bug where More -> ANRFC Lister link was the wrong size and did not match the style of the skin

- Fixed bug where no signature or a signature too far down caused it to hang forever

- Added a "Cancel" button to the form

- No longer displays on special pages, diffs, editing a page, etc.

- Clicking "Would you like to see it?" now takes you to exact section, instead of top of page.

- Fixed duplicate RFC listing detection.

- Titles shouldn't have underscores

- Fixed bug where the script would always give "signature not found" error if you had MediaWiki:Gadget-CommentsInLocalTime.js gadget installed



NOVEM LINGUAE TODO:

- test unicode titles

- test titles with weird punctuation in section names, e.g. ending in ?

- get it working in Minerva
