It is niche, but official project pages provide enough release history to document it as a traditional Unix-style game package. ### プロジェクトの歴史 The official homepage says CHEOPS was conceived and written by Tristan Miller and describes it as a fully functional chess program supporting human-vs-human, human-vs-computer, and computer-vs-computer play. It uses a 64-square linear board representation, alpha-beta search, and a static evaluation function over material, mobility, and motif features. The NEWS file records an initial 1.0 release in November 2003, GNU-style packaging with configure script and man page in 1.1, compiler compatibility fixes in 1.2, and GPL-3.0 relicensing in 1.3. ### 採用の歴史 The project is small, but the homepage documents source releases on GitHub and nothingisreal.com, openSUSE packages, and third-party Windows builds. The batch metadata lists Homebrew and MacPorts packaging. CHEOPS is therefore more of a preserved portable Unix game than a widely adopted chess engine ecosystem project. ### 使われ方 Users run cheops in a terminal, choose who controls each side, optionally adjust computer-opponent evaluation weights, and enter moves in coordinate notation such as g1f3. The man page documents commands for help, resigning, redisplaying the board, reversing the board, showing computer thinking, logging, saving, starting a new game, and quitting. The package builds with a standard configure script on Unix-like systems, matching the expectations of source-based package managers and ports collections. ### パッケージ好きにとっての重要性 CHEOPS is package-nerd significant mainly as a small, old-school Unix game package: source tarballs, configure and make, a section 6 man page, GPL licensing, and ports-package distribution. It also shows why package managers keep niche software alive: even a four-star chess program can remain installable decades after its first release when it follows conventional source distribution patterns. ### タイムライン - 2003: CHEOPS 1.0 initial release. - 2003: CHEOPS 1.1 added GNU-style packaging, configure script, man page, and --help/--version. - 2015: CHEOPS 1.2 fixed compilation with modern GCC. - 2016: CHEOPS 1.3 released and relicensed under GPL-3.0. ### Related projects - GNU Chess, chesstool, and xboard are listed in the CHEOPS man page as related tools. - openSUSE packaging and MacPorts/Homebrew formulas are relevant distribution relatives for this kind of Unix game. ### ソース - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** cheops - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - MacPorts - cheops: normalized package name match | MacPorts ports tree: games/cheops/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 関連リンク - [Terminal utility packages](https://pkg.so/ja/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/ja/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Game and emulation packages](https://pkg.so/ja/game-emulation-tools/) - Matched game or emulation metadata. - [Homebrew utility packages](https://pkg.so/ja/brew-utility-packages/) - Matched Homebrew package provider. - [fairymax](https://pkg.so/ja/brew/fairymax/) - Shares pkgdb curated category or tags: chess, cli, engine, games. - [fairy-stockfish](https://pkg.so/ja/brew/fairy-stockfish/) - Shares pkgdb curated category or tags: chess, cli, engine, games. - [lc0](https://pkg.so/ja/brew/lc0/) - Shares pkgdb curated category or tags: chess, cli, engine, games. - [polyglot](https://pkg.so/ja/brew/polyglot/) - Shares pkgdb curated category or tags: chess, cli, games. - [xboard](https://pkg.so/ja/brew/xboard/) - Shares pkgdb curated category or tags: chess, cli, game, games. - [stockfish](https://pkg.so/ja/brew/stockfish/) - Shares pkgdb curated category or tags: chess, cli, games. - [nethack](https://pkg.so/ja/brew/nethack/) - Shares pkgdb curated category or tags: cli, game, games. - [freeciv](https://pkg.so/ja/brew/freeciv/) - Shares pkgdb curated category or tags: cli, game, games. ## Combined YAML source View the package source record on GitHub.
