history

Project history and usage

ccls is a C, C++, and Objective-C language server. Its README says it originates from cquery and supports completion, cross references, hierarchies, formatting, diagnostics, semantic highlighting, and whole-project indexing.

Project history

The official GitHub repository was created in March 2018. The README explicitly frames ccls as originating from cquery, another C/C++ language-server project, and describes ccls' distinguishing emphasis on indexing the whole project while serving requests before indexing is complete.

Adoption history

The supplied package facts show ccls packaged broadly across Alpine, Homebrew, Debian, MacPorts, Nix, Arch, Ubuntu, and openSUSE. That spread reflects language-server adoption by editors and distributions after the Language Server Protocol became common infrastructure.

How it is used

A typical ccls setup gives the server a project-root compile_commands.json generated by the build system, or a project-root .ccls file containing compiler flags. Editors then speak LSP to ccls for code completion, navigation, references, diagnostics, and semantic highlighting.

Why package nerds care

ccls is significant because it packages a clang-based language server as a standalone system dependency instead of binding users to one editor extension. For package managers, it is the sort of developer-tool daemon that makes editor integrations reproducible across machines.

Timeline

2018: GitHub repository created.
2018: README documents ccls as originating from cquery and able to index itself, FreeBSD, glibc, Linux, LLVM, and musl.
2025: GitHub tags show continued dated releases.

Related projects

The README names cquery as the origin project and relies on clang-style compilation databases such as compile_commands.json.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.

Configuration and credential file locations

These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval.
