Description

A simple search and replace in non-regex mode is ending up raising an error.

What I Did

KeyError: 'new_version'

As you can see in the verbose logs, bump-my-version is trying to locate the 2\\.18\\.0 version regexp. Which is surprising to me as I was not expecting it to handle versions at all. Instead, I am expecting it to search for the profanity string and replace it with an empty string.

Note that I am performing this from a project, whose pyproject.toml contains:

[tool.bumpversion]
current_version = "2.19.0"
allow_dirty = true
no_regex = true

[[tool.bumpversion.files]]
filename = "./changelog.md"
no_regex = true
search = "## [{current_version} (unreleased)]("
replace = "## [{new_version} (unreleased)]("

But its content has no influence, as deleting it still produce the same error.

This issue is still present in 0.12.0:

pyproject.toml:

[tool.bumpversion]
current_version = "2.20.7"
allow_dirty = true

[[tool.bumpversion.files]]
filename = "./changelog.md"
search = "## [{current_version} (unreleased)]("
replace = "## [{new_version} (unreleased)]("

changelog.md:

# Changelog

## [2.20.7 (unreleased)](https://github.com/kdeldycke/workflows/compare/v2.20.6...main)

- Test profanity.

+1 here. Any updates on this?

I'll be on vacation until the end of the year, which will open up my time to focus on clearing up the backlog here.

I appreciate your patience.
