## Using pip package
Install the package:
```
pip install pr-agent
```
Then run the relevant tool with the script below.
<br>
Make sure to fill in the required parameters (`user_token`, `openai_key`, `pr_url`, `command`):
```python
from pr_agent import cli
from pr_agent.config_loader import get_settings
def main():
# Fill in the following values
provider = "github" # github/gitlab/bitbucket/azure_devops
user_token = "..." # user token
openai_key = "..." # OpenAI key
pr_url = "..." # PR URL, for example 'https://github.com/Codium-ai/pr-agent/pull/809'
command = "/review" # Command to run (e.g. '/review', '/describe', '/ask="What is the purpose of this PR?"', ...)
# Setting the configurations
get_settings().set("CONFIG.git_provider", provider)
get_settings().set("openai.key", openai_key)
get_settings().set("github.user_token", user_token)
# Run the command. Feedback will appear in GitHub PR comments
cli.run_command(pr_url, command)
if __name__ == '__main__':
main()
```
## Using Docker image
A list of the relevant tools can be found in the [tools guide](../tools/ask.md).
To invoke a tool (for example `review`), you can run directly from the Docker image. Here's how:
- For GitHub:
```
docker run --rm -it -e OPENAI.KEY=<your key> -e GITHUB.USER_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
```
If you are using GitHub enterprise server, you need to specify the custom url as variable.
For example, if your GitHub server is at `https://github.mycompany.com`, add the following to the command:
```
-e GITHUB.BASE_URL=https://github.mycompany.com/api/v3
```
- For GitLab:
```
docker run --rm -it -e OPENAI.KEY=<your key> -e CONFIG.GIT_PROVIDER=gitlab -e GITLAB.PERSONAL_ACCESS_TOKEN=<your token> codiumai/pr-agent:latest --pr_url <pr_url> review
```
If you have a dedicated GitLab instance, you need to specify the custom url as variable:
```
-e GITLAB.URL=<your gitlab instance url>
```
- For BitBucket:
```
docker run --rm -it -e CONFIG.GIT_PROVIDER=bitbucket -e OPENAI.KEY=$OPENAI_API_KEY -e BITBUCKET.BEARER_TOKEN=$BITBUCKET_BEARER_TOKEN codiumai/pr-agent:latest --pr_url=<pr_url> review
```
For other git providers, update `CONFIG.GIT_PROVIDER` accordingly and check the `pr_agent/settings/.secrets_template.toml` file for environment variables expected names and values.
The `pr_agent` uses [Dynaconf](https://www.dynaconf.com/) to load settings from configuration files.
It is also possible to provide or override the configuration by setting the corresponding environment variables.
You can define the corresponding environment variables by following this convention: `<TABLE>__<KEY>=<VALUE>` or `<TABLE>.<KEY>=<VALUE>`.
The `<TABLE>` refers to a table/section in a configuration file and `<KEY>=<VALUE>` refers to the key/value pair of a setting in the configuration file.
For example, suppose you want to run `pr_agent` that connects to a self-hosted GitLab instance similar to an example above.
You can define the environment variables in a plain text file named `.env` with the following content:
> Warning: Never commit the `.env` file to version control system as it might contains sensitive credentials!
```
CONFIG__GIT_PROVIDER="gitlab"
GITLAB__URL="<your url>"
GITLAB__PERSONAL_ACCESS_TOKEN="<your token>"
OPENAI__KEY="<your key>"
```
Then, you can run `pr_agent` using Docker with the following command:
```shell
docker run --rm -it --env-file .env codiumai/pr-agent:latest <tool> <tool parameter>
```

## Run from source
1. Clone this repository:
```
git clone https://github.com/Codium-ai/pr-agent.git
```
2. Navigate to the `/pr-agent` folder and install the requirements in your favorite virtual environment:
```
pip install -e .
```
*Note: If you get an error related to Rust in the dependency installation then make sure Rust is installed and in your `PATH`, instructions: https://rustup.rs*
3. Copy the secrets template file and fill in your OpenAI key and your GitHub user token:
```
cp pr_agent/settings/.secrets_template.toml pr_agent/settings/.secrets.toml
chmod 600 pr_agent/settings/.secrets.toml
# Edit .secrets.toml file
```
4. Run the cli.py script:
```
python3 -m pr_agent.cli --pr_url <pr_url> review
python3 -m pr_agent.cli --pr_url <pr_url> ask <your question>
python3 -m pr_agent.cli --pr_url <pr_url> describe
python3 -m pr_agent.cli --pr_url <pr_url> improve
python3 -m pr_agent.cli --pr_url <pr_url> add_docs
python3 -m pr_agent.cli --pr_url <pr_url> generate_labels
python3 -m pr_agent.cli --issue_url <issue_url> similar_issue
...
```
[Optional] Add the pr_agent folder to your PYTHONPATH
```
export PYTHONPATH=$PYTHONPATH:<PATH to pr_agent folder>
```
