source_directory
Requirements Generator Tool: Manage requirements, versioning, and virtual environments for Python projects.
positional arguments:
source_directory Directory to recursively search for Python files and generate requirements from imports.
optional arguments:
-h, --help show this help message and exit
--output_directory OUTPUT_DIRECTORY
Directory to save generated files.
--env-name ENV_NAME Specify the name of the virtual environment to create (default: 'env').
--list-envs List all virtual environments.
--no-env Skip creating a virtual environment and install dependencies in the global Python environment.
--project-name PROJECT_NAME
Set the project name for pyproject.toml (default: 'auto_generated_project').
--project-description PROJECT_DESCRIPTION
Set the project description for pyproject.toml (default: 'A project generated by RequirementsGenerator').
--project-author PROJECT_AUTHOR
Set the project author for pyproject.toml (default: 'Your Name <you@example.com>').
--pin PIN Pin a dependency to a specific version. Usage: --pin package==version. Can be used multiple times.
--skip-install Skip the installation of dependencies after generating requirements.
--merge-requirements Merge newly detected dependencies into an existing requirements.txt file, instead of overwriting it.
--dev Include development dependencies (like pytest, black) in pyproject.toml.
--pipfile Generate a Pipfile for pipenv users (in addition to requirements.txt and pyproject.toml).
--verbose Enable verbose logging for detailed output during the execution.
--bump {major,minor,patch}
Bump the version in pyproject.toml:
major: Increment the major version (e.g., 1.0.0 -> 2.0.0)
minor: Increment the minor version (e.g., 1.1.0 -> 1.2.0)
patch: Increment the patch version (e.g., 1.1.1 -> 1.1.2)
--log-file LOG_FILE Specify a log file to save logs.
--dockerfile Generate a Dockerfile for the project.
--visualize-graph Visualize the dependency graph.
--main-script MAIN_SCRIPT
Specify the main script to run in the Docker container (default: 'your_script.py').
--package-manager {uv,poetry,pip}
Specify the package manager to use (default: 'pip').
--python-env-version PYTHON_ENV_VERSION [PYTHON_ENV_VERSION ...]
Specify the Python versions to use for the virtual environments (default: 'python3').
--activate-env ACTIVATE_ENV
Activate a specific virtual environment by specifying the env path.
--deactivate-env DEACTIVATE_ENV
Deactivate virtual environment.
--create-reqs-file Create a requirements.txt file.
--create-pyproject Create a pyproject.toml file.
```
