When you accept callbacks from users of your library, backcall lets you define a prototype function that describes the expected signature, then automatically adapts incoming callbacks to match it. If a callback has fewer parameters than the prototype, backcall wraps it to discard extras; if it requires more, backcall raises a TypeError at registration time rather than at call time.\n\nThe package has no runtime dependencies and installs cleanly. It is designed for library authors who want to evolve their callback APIs without breaking existing user code. However, the project has been abandoned since 2020 with no recent maintenance, so it should only be used in stable, low-change codebases or as a reference for implementing similar validation logic.","worth_installing":"Yes, if you are maintaining a library with a stable callback API and want lightweight signature validation without dependencies. No, if you need active maintenance or are starting a new project\u2014the package is abandoned and there are no recent updates. Consider it for mature, low-change codebases only."},"id":"backcall","links":{"html":"https://skillfed.io/packages/backcall","md":"https://skillfed.io/packages/backcall.md","pypi":"https://pypi.org/project/backcall/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2020-06-09","license_spdx":null,"license_treatment":"permissive","name":"backcall","python_support":"unspecified","summary":"Specifications for callback functions passed in to an API"},"popularity":{"monthly_downloads":14815737,"position":1216,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.2.0"}
