{"id":7348,"library":"la-panic","title":"AppleOS Kernel Panic Parser","description":"la-panic is a Python library primarily designed as a command-line tool for parsing AppleOS (specifically iOS) kernel panic reports, also known as crash reports. It helps extract structured information from `.ips` files, which are generated by Apple devices upon system crashes. The current version is 0.5.0, released on November 12, 2023. Its release cadence appears irregular, typical for specialized utility libraries.","status":"active","version":"0.5.0","language":"en","source_language":"en","source_url":"https://gitlab.com/yanivhasbanidev/la_panic","tags":["macos","ios","kernel","panic","parser","crash-reports"],"install":[{"cmd":"pip install la-panic","lang":"bash","label":"Install latest version"}],"dependencies":[],"imports":[{"note":"la-panic is predominantly a command-line interface (CLI) tool.
