        "description": "# Module Graph\n\nShow python modules dependency graph and static memory usage.\n\n## Install\n\nFirst you need [graphviz](https://www.graphviz.org/) installed in your system.\n\n- Mac:\n\n    ```\n    brew install graphviz\n    ```\n\n- Ubuntu:\n\n    ```\n    sudo apt-get update\n    sudo apt-get install graphviz libgraphviz-dev pkg-config\n    ```\n\nThen:\n\n```\npip install 'module-graph[all]'\n```\n\n## Usage\n\n### Analysis current installed modules\n\nTravel all modules and generate graph data:\n\n```\npython -m module_graph.run_traveler\n```\n\nCommand reference:\n\n```\nusage: run_traveler.py [-h] [--modules MODULES] [--ignore IGNORE]\n\nModule Graph Traveler\n\noptional arguments:\n  -h, --help         show this help message and exit\n  --modules MODULES  top level modules to check, default all modules\n  --ignore IGNORE    ignore modules (shell patterns)\n```\n\n### Analysis modules used by application\n\n> **Warning**: the hooker will do crazy patch to `sys` module, your application may be slower or crash!\n\nSetup hooker as early as possible in application.\n\n```python\nimport module_graph\n\nif __name__ == \"__main__\":\n    memory_hooker = module_graph.setup_hooker(\n        save_to='data/module_graph.json', verbose=True)\n```\n\nRun your aplication for a while, then stop it.\nThe hooker will generate data for all modules used by application.\n\n### Render graph\n\nUse `module-graph` command to render graph, for example:\n\n```\nmodule-graph --input-filepath data/module_graph.json\n```\n\nCommand reference:\n\n```\nusage: module-graph [-h] [--modules-filepath MODULES_FILEPATH]\n                    [--input-filepath INPUT_FILEPATH]\n                    [--output-filepath OUTPUT_FILEPATH]\n                    [--threshold THRESHOLD]\n\nModule Graph Render\n\noptional arguments:\n  -h, --help            show this help message and exit\n  --modules-filepath MODULES_FILEPATH\n                        modules to render, default all modules\n  --input-filepath INPUT_FILEPATH\n                        the module graph data generated by hooker (json file)\n  --output-filepath OUTPUT_FILEPATH\n                        render output PDF filepath\n  --threshold THRESHOLD\n                        donot show module which memory usage < threshold (MB)\n```\n\n## How it work\n\nIt patch `sys.meta_path`, `sys.modules` and all module loaders,\nthen record memory before and after module import.\n\n## License\n\nThis package is distributed under the MIT license.",
