## プロジェクトの歴史と使われ方

bcal is a small C command-line calculator aimed at people who think in bytes, sectors, addresses, and binary prefixes.

### プロジェクトの歴史

The upstream GitHub repository was created in 2016. Its README describes bcal, the Byte CALculator, as a REPL and single-shot CLI for storage expressions, SI/IEC conversion, byte address calculation, base conversion, and CHS/LBA calculations.

The project keeps dependencies modest: standard libc plus GNU Readline or BSD Editline, with a no-readline build option that uses its own prompt and history-file support.

### 採用の歴史

bcal is packaged beyond Homebrew, including Debian, Fedora, Nix, Ubuntu, and openSUSE-family package sets in the supplied package-manager facts. Its README points users to package-manager installation first and shows Repology packaging status.

### 使われ方

Users run bcal as an interactive storage calculator, pass quoted expressions for one-shot evaluation, convert between decimal, hexadecimal, binary, SI, and IEC units, or calculate disk CHS/LBA values.

When built without Readline, its history file is stored under $XDG_CONFIG_HOME/bcal/history or $HOME/.config/bcal/history.

### パッケージ好きにとっての重要性

bcal is the kind of niche CLI package that saves repeated mental arithmetic for storage engineers, filesystem debuggers, firmware people, and anyone reading sector offsets in hex.

Its significance is not ecosystem scale but fit: it packages a cluster of byte-addressing calculations that general calculators rarely make pleasant.

### タイムライン

- 2016: GitHub repository created.
- 2018: README-linked asciinema demo published.
- 2020s: Packaged in Homebrew and several Linux distributions.

### Related projects

- bc and dc cover general arbitrary-precision calculation but not bcal's storage-unit and disk-addressing workflow.
- disk utilities, hex calculators, and filesystem debugging tools overlap with bcal's audience.
