how to keep formula updated when deps are updated?

[ipatch]

i searched through all the discussion threads in the tap maintenance category in this discussion "repo" and saw some similar questions related to keeping a formula updated, but that's not exactly what i'm looking for.

my for use case (example), i created a [email protected] formula file for the freecad tap. when i triggered our CI to build the bottle for shiboken the current upstream python was at [email protected], the upstream (homebrew-core) python formula has since been updated to [email protected] thus when i run,

$bp/bin/python3

Python 3.10.4 (main, Apr 26 2022, 19:43:07) [Clang 12.0.0 (clang-1200.0.32.29)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

>>> import shiboken
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'shiboken'
>>>

my current python installation no longer works with my shiboken2 install. 🤷‍♂️

if i look at the install receipt for my shiboken2 installl i see,

}

it's still referencing python 3.10.2

as a tap maintainer, how can i keep tap based formula updated when a homebrew-core formula updates, and make sure the bottles are built using the correct versions of the dependencies?

You'll have to keep track of the upstream updates and issue revision bumps whenever a dependency updates.
