# Context:
USER: write a dcript that takes x.y.z semver on the cmd line. it should:
1. verify that the version is greater than `__version__`
2. wupdate the `__version__` in init.py
3. git commit that change with msg `version bump to x.y.z`
4. git tag that new commit with "vx.y.z" (note the leading v)
5. git push to origin
6. git push the new tag to origin
ASSISTANT: I will create a new script called `scripts/versionbump.py` to handle the version bumping process. Here are the changes:
```python
scripts/versionbump.py
<<<<<<< ORIGINAL
=======
import argparse
import os
import re
import subprocess
from packaging import version
def main():
parser = argparse.ArgumentParser(description="Bump version")
parser.add_argument("new_version", help="New version in x.y.z format")
args = parser.parse_args()
new_version = version.parse(args.new_version)
if not isinstance(new_version, version.Version):
raise ValueError("Invalid version format")
with open("aider/__init__.py", "r") as f:
content = f.read()
current_version = re.search(r'__version__ = "(.+?)"', content).group(1)
if new_version <= version.parse(current_version):
raise ValueError("New version must be greater than the current version")
updated_content = re.sub(r'__version__ = ".+?"', f'__version__ = "{new_version}"', content)
with open("aider/__init__.py", "w") as f:
f.write(updated_content)
subprocess.run(["git", "add", "aider/__init__.py"])
subprocess.run(["git", "commit", "-m", f"version bump to {new_version}"])
subprocess.run(["git", "tag", f"v{new_version}"])
subprocess.run(["git", "push", "origin"])
subprocess.run(["git", "push", "origin", f"v{new_version}"])
if __name__ == "__main__":
main()
>>>>>>> UPDATED
```
This script will perform the requested actions. Make sure to install the `packaging` library if you haven't already:
```bash
pip install packaging
```
You can run the script with the new version as an argument:
```bash
python scripts/versionbump.py x.y.z
```
