version_files relative to configuration file?

[akiross]

Hello,

from the documentation, it seems that paths in version_files can be either

• relative to execution path
• absolute path
• glob patterns

I might be missing something, but IMHO a sensible option would be to also specify files relatively to the commitizen configuration file's path. For example:

# /home/myself/project/cz.toml
[tool.commitizen]
version_files = [
    "src/__version__.py", # relative to execution path: won't update if we call `cz bump` from the project `src` dir
    "$CZCONFIG/src/__version__.py", # relative to where the cz config file is, will always update the file
]

In this case, $CZCONFIG would make that path relative to /home/myself/project/.

Is something like this currently possible?

EDIT: clearly I'm avoiding absolute paths so that configurations can be shared among multiple workstation/people/locations/etc.
