File resolution rules

[coordt]

Description

Ensure the following rules are followed for resolving file locations (and document them):

• when specified on the command line:
  • relative paths are resolved from the current working directory
  • full paths are used as-is
• when specified in the configuration file
  • relative paths are resolved from the location of the configuration file
  • full paths are used as-is

Option: A formatting option, like {repo_root}, allows the path to specify it is relative to the code repo's root.

For example:

[[ tool.bumpversion.files ]]
filename = "{repo_root}/mylibrary/__init__.py"
