Dear maintainer,
This watch file does not work:
Version: 5
Template: Github
Owner: micropython
Project: micropython
Matching-Pattern:
https://api.github.com/repos/[^/]+/[^/]+/git/refs/tags/v?(\d[\d.]*)(?=")

Hi,
I have verified that using
Matching-Pattern:
https://api.github.com/repos/[^/]+/[^/]+/git/refs/tags/v?(\d[\d.]*)(?:(?=")|$)
works (is what is used internally for Matching-Pattern in Github
template when Matching-Pattern is not explicitly set). So, this seems
not that look ahead possitive regexp is not working but that uscan may
preprocess the string before trying match (and probably strips
trailing double quote)
So, you may fix this in some ways,
* Using above matching pattern.
* Using "Release-Only: yes" in your v5 debian/watch (without
explicitly setting Matching-Pattern:).
* Using "Version-Type: STABLE_VERSION" in your v5 debian/watch
(without explicitly setting Matching-Pattern:).
* Using "Custom-Version: v?(\d[\d.]*)" in your v5 debian/watch
(without explicitly setting Matching-Pattern:), introduced in
devscripts 2.26.8, about to reach testing.
Depending on your exact needs not all above possibilities may get
exactly what you want.
I am closing this bug report with the version 2.26.8 was introduced
(all other things were introduced earlier). Please reopen if you think
this needs further work.
Thanks fot pointing out this problem.
