Add bot directive to remove a patch on a new release

[tdegeus]

Your question:

What happens from time-to-time is that a minor bug appears in an already released version (e.g. here). A nice option for the feedstock is to add a patch. However, this adds a maintenance burden as the patch has to be removed on the next release. It would be nice to have the bot do this.

For example:

{% set version = "10.1.1" %}

source:
   url: https://github.com/fmtlib/fmt/archive/{{ version }}.tar.gz
   sha256: {{ sha256 }}
   patches:
     - patches/0001-fix-core-version-10.1.1.patch   # [delete >{{ version }}]

Upon upgrading to 10.1.2 (or any version higher than 10.1.1) the bot could then remove the patch from meta.yaml and remove the patch file.

You can always apply a selector using thr version directly to the line in the recipe with the patch. This won’t remove the line in the file but will remove the patch.

From the docs I could not find a selector that does it. Do you rather mean one could use jinja2 ?

{% set version = "10.1.1" %}

source:
   url: https://github.com/fmtlib/fmt/archive/{{ version }}.tar.gz
   sha256: {{ sha256 }}
{% if {{ version }} == "10.1.1" %}
   patches:
     - patches/0001-fix-core-version-10.1.1.patch
{% endif %}

Indeed, that is not too bad. Still it would be nice to have a bot command to automatically clean-up.
