peotry version doesn't bump the value in __version__

$ poetry version 0.1.1
Bumping version from 0.1.0 to 0.1.1
$ grep version pyproject.toml 
version = "0.1.1"
$ grep version */__init__.py
src/__init__.py:__version__ = '0.1.0'
$ poetry --version
Poetry 0.9.0

I don’t know if it’s intended or not. A way to do that safely is to parse the root __init__.py, detect __version__, back it up, extract the ast, bump the version string and replace it, then extract the new ast and compare the result. If both ast are the same, except for the version, the file semantics have been preserved. Otherwise, rollback the change and display an error message stating we can’t bump the version safely.

I really wish that the version field in the .toml ended up superseding the __version__ string in __init__.py. This would reduce the burden of having to keep multiple places in the code in sync.

you may use that

import toml
from pathlib import Path

def get_version():
   path = Path(__file__).resolve().parents[1] / 'pyproject.toml'
   pyproject = toml.loads(open(str(path)).read())
   return pyproject['tool']['poetry']['version']

__version__ = get_version()
