It targets static key sets where compact storage and collision-free lookup matter more than insertion or deletion. ### プロジェクトの歴史 The CMPH site frames the project around a gap in free software support for minimal perfect hashing, distinguishing it from GNU gperf by emphasizing very large key sets rather than small generated perfect-hash functions. Its documentation collects several algorithms, including CHD, BDZ, BMZ, BRZ, CHM, and FCH. By the 1.x and 2.x news entries, CMPH had grown beyond a single algorithm implementation into a practical library with packed-function support, memory-mappable output, an external-memory BRZ path for very large sets, and an experimental C++ interface for map-like use cases. ### 採用の歴史 CMPH has remained a niche but durable package because minimal perfect hashes are a specialized data-structure tool. It appears in Homebrew, Debian and Ubuntu development packages, MacPorts, Nix, Alpine, and other package collections for developers who need static dictionary or key-index construction. ### 使われ方 Typical usage is offline construction of a hash function from a fixed key set, followed by storage or embedding of the generated function. The official examples show the C API creating a minimal perfect hash from an in-memory vector and dumping it to a file. ### パッケージ好きにとっての重要性 CMPH is the kind of package that matters disproportionately to systems and search developers: it packages academic minimal-perfect-hashing algorithms into a reusable C interface and a small CLI. Its appeal is that it turns a static corpus into dense one-probe lookup tables without hauling in a database. ### タイムライン - 0.9: CHD and CHD_PH support highlighted for compact internal-memory minimal perfect hashes. - 1.0: Bugfix-only release before a planned revamp of code and algorithms. - 1.1: CHD_PC bug fix and test reorganization. - 2.0: Warning cleanup and experimental C++ mph_map and mph_index interface. ### Related projects - Related projects and concepts include GNU gperf, static hash tables, CHD, BDZ, BMZ, BRZ, CHM, and FCH minimal-perfect-hashing algorithms. ### ソース - - - - ## セキュリティノート library-like package without higher-risk signals. -
