Bump each commit + patch patter does not update changed output correctly

[PaulHatch]

Discussed in #139

^{Originally posted by rmendal February 29, 2024}
Hi, I'm running this action in my repo and I want it to increment the version when there is a change to the docs directory AND one of the keywords for bump_each_commit_patch_pattern is met. I do have bump_each_commit set to true as well.

It's entirely possible I'm not understanding the docs and doing this wrong but I'm assuming that based on my code below that if I make a change in the docs dir AND make a commit with a message like, "minor docs update" that the changed output will be true otherwise it will be false. However, if I don't make any changes in docs the changed output is always true. This includes commit messages that don't contain any pattern keywords. Possibly worth mentioning that I've disabled bump_each_commit but that had no effect.

Please tell me what I'm doing wrong here.
