The bytecode transformer will remove the values of these annotation parameters from the string representation\nof that particular class.\n\n![Demonstration](.assets/demo.jpg)\n\nThe project is divided into three Gradle modules:\n\n- `api` defines two custom marker annotations\n- `app` is a basic Jetpack Compose application to showcase the effects of the Transformer at runtime\n- `transformer` provides the implementation of the custom Transformer\n\n## License\n\n```\nCopyright 2023 Marcel Schnelle\n\nLicensed under the Apache License, Version 2.0 (the \"License\");\nyou may not use this file except in compliance with the License.\nYou may obtain a copy of the License at\n\n  http://www.apache.org/licenses/LICENSE-2.0\n\nUnless required by applicable law or agreed to in writing, software\ndistributed under the License is distributed on an \"AS IS\" BASIS,\nWITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied.\nSee the License for the specific language governing permissions and\nlimitations under the License.\n```\n\nSee also the [full License text](LICENSE).\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmannodermaus%2Fdk23-bytecode","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmannodermaus%2Fdk23-bytecode","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmannodermaus%2Fdk23-bytecode/lists"}
