Its README describes a client/server design with an Emacs Lisp client and a C server binary named clang-complete. ### Adoption history Homebrew packages the project at version 0.5 from the official GitHub tag. Official public metadata is otherwise thin, so broader adoption history should be treated cautiously. ### How it is used Users build the clang-complete server with make, copy the Emacs Lisp file and binary into ~/.emacs.d, add setup code to .emacs, and optionally configure clang flags in .emacs or .dir-locals.el. ### Why package nerds care The package is relevant to editor and package-manager users as an older Emacs completion integration that wrapped libclang before newer language-server workflows became dominant. ### Timeline - 2012: GitHub repository created - 2017: Repository last pushed according to GitHub API metadata - 2026: Homebrew formula tracks v0.5 ### Related projects - The README references auto-complete and libclang as core dependencies in the completion workflow. ### Sources - GitHub repository API: created_at 2012-05-13, language Emacs Lisp, pushed_at 2017-01-26 - GitHub tags API: v0.5 tag exists - Homebrew formula API: stable version 0.5 and official source archive - Official README: introduction, setup, usage, and relationship to libclang and auto-complete ## Security Notes broad file, network, media, or database tool signal. - **Geiger risk:** blue / medium - broad file, network, media, or database tool signal ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
