## 项目历史与用法

Clac is a command-line, stack-based calculator using postfix notation with the stack visible as calculations happen.

### 项目历史

The official repository was created in 2017 and its first GitHub release was named Initial release. The README explains the project motivation: the author liked Forth and other concatenative languages, used `dc` heavily, and wanted a calculator UI with an always-visible stack and realtime updates.

### 采用历史

The batch input records Clac in Homebrew, MacPorts, and Nix. The official README directs users to GitHub releases and a distribution-packages wiki page, indicating upstream expected both direct release installs and package-manager installs.

### 使用方式

Users run `clac` interactively, enter numbers to push them onto the stack, and type postfix commands such as arithmetic, logarithm, trigonometry, stack, stash, and custom word operations. The README documents a `words` configuration file for user-defined operations.

### 为什么软件包爱好者会关心

Clac is a neat package-manager specimen because it modernizes the tiny terminal calculator niche rather than replacing it with a GUI. It is small, self-contained, configurable through XDG-style paths, and culturally adjacent to `dc`, Forth, and RPN calculator users.

### 时间线

- 2017: Official GitHub repository created.
- 2017: Initial release 0.1.0 published.
- 2026: Official GitHub repository metadata shows recent activity.

### Related projects

- The README explicitly relates Clac to `dc`, Forth, stack-based languages, concatenative languages, postfix notation, and reverse Polish notation.
