It targets CMakeLists.txt, CMakeLists.txt.in, .cmake, and .cmake.in files, and aims to provide a low-configuration formatting style for build-system code. ### Project history The gersemi repository was opened in 2020. Its README describes a formatter that can be installed from PyPI, run as a command-line tool, configured with `.gersemirc`, and integrated into pre-commit through a dedicated hook repository. ### Adoption history gersemi fills a practical niche for projects that already enforce code style but also want deterministic formatting for CMake files. Package availability through Homebrew, Nix, and Windows package metadata reflects use beyond direct PyPI installs. ### How it is used Practitioners run gersemi in check, in-place, or diff mode across files or directories. The tool discovers common CMake file names, reads formatting configuration from `.gersemirc` or command-line flags, supports custom command definitions and extensions, and can be used in pre-commit hooks. ### Why package nerds care For package-manager users, gersemi is useful because it brings Black-like formatting habits to CMake projects through a single CLI. It is especially handy in CI and pre-commit setups where reproducible formatting matters more than editor-specific integrations. ### Timeline - 2020: The gersemi repository was opened on GitHub. - 2020s: The README documents PyPI installation, CLI modes, `.gersemirc`, pre-commit integration, extensions, cache support, and ignore-file handling. ### Related projects - CMake, pre-commit, PyPI, gersemi-pre-commit ### Sources - - - - ## Security Notes No matching local secret-handling manifest was found for gersemi. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
