## プロジェクトの歴史と使われ方

Clozure CL is a free Common Lisp implementation with roots in Macintosh Common Lisp and OpenMCL.

### プロジェクトの歴史

The official history traces CCL back to Coral Software's 1984 work on Coral Common Lisp for the Macintosh. CCL 1.0 shipped in 1987 for the Macintosh Plus, then the line passed through Macintosh Allegro Common Lisp and Apple's Macintosh Common Lisp.

Apple transferred MCL to Digitool in 1994 during the PowerPC transition, and Digitool released a PowerPC version around 1995. A JPL effort later licensed MCL source for PowerPC robotics and flight-system work; Gary Byers ported the compiler and runtime to VxWorks and LinuxPPC in 1998.

Digitool agreed in 2001 to open source the JPL work, creating OpenMCL. In 2007, OpenMCL was renamed Clozure CL to avoid confusion with the newly open sourced original MCL code.

### 採用の歴史

The official site describes Clozure CL as available across macOS, Linux, FreeBSD, illumos, and Windows, which made it a portable Common Lisp for users who wanted native threads, fast compilation, a compacting generational garbage collector, and a foreign-function interface.

For package managers, Clozure CL matters as a long-lived Lisp runtime that exposes a simple `ccl64` executable while carrying decades of Mac Lisp lineage into Unix-style packaging.

### 使われ方

Users run `ccl64` for the Clozure CL listener/compiler and can build CCL from source using an already-working CCL, because the implementation is written in itself.

The project documents user support through the ccl-devel mailing list, IRC, GitHub issues, and release downloads from GitHub.

### パッケージ好きにとっての重要性

Clozure CL is unusually interesting to package maintainers because it is self-hosting, historically tied to Macintosh Lisp, and packaged as a full language runtime rather than a small utility.

Its init-file behavior and architecture-specific binaries are the sort of details that make Lisp implementations visible in Homebrew and other Unix packaging ecosystems.

### タイムライン

- 1984: Coral Software began Coral Common Lisp for the Macintosh.
- 1987: CCL 1.0 was released for a 1 MB Macintosh Plus.
- 1988: Coral was acquired by Apple, and the Lisp became Macintosh Common Lisp.
- 1994: Apple transferred MCL to Digitool.
- 1998: A JPL-backed port of the MCL compiler and runtime reached VxWorks and LinuxPPC.
- 2001: Digitool agreed to open source the JPL work, creating OpenMCL.
- 2007: OpenMCL was renamed Clozure CL.
- 2017: GitHub releases include Clozure CL 1.11.
