## プロジェクトの歴史と使われ方
ascii is Eric S. Raymond's compact Unix reference utility for translating among ASCII character names, byte values, numeric bases, Teletype mnemonics, ISO/ECMA code positions, XML entity names, and slang names. Called without arguments, it prints a small ASCII chart.
### プロジェクトの歴史
The official NEWS file records the first release by Eric S. Raymond as version 1.0 in March 1990. Through the 1990s it accumulated ISO-style code table escapes, contributed changes, a splash-screen idea, and option changes; version 3.0 in July 2000 added HTML/SGML entity names.
The modern 3.x line continued as a maintenance-oriented C utility. The NEWS file records a 2010 license change to BSD and ANSI C cleanup, 2011 additions from Debian, a 2013 Makefile fix from MacPorts, a 2015 project metadata move away from Gitorious, 2017 binary table output, 2024 CLI flag handling updates, and 2026 hardening/packaging work.
### 採用の歴史
The official resource page states that the code is usually packaged as `ascii` and displays Repology package status. The input package facts show the formula is available across Homebrew, Debian, Fedora/DNF, MacPorts, Nix, Arch, Ubuntu, and openSUSE/Zypper, reflecting the utility's long-lived role as a tiny reference program in Unix collections.
### 使われ方
Package users typically install it for fast terminal lookup: provide a character, number, escape, mnemonic, or entity name and ascii prints the corresponding representations; run it with no arguments to get a chart. Recent options can force output radix with `-d`, `-o`, `-x`, or `-b`.
### パッケージ好きにとっての重要性
ascii is package-nerd catnip because it is a small, old, useful command that survived several hosting eras and kept receiving portability and packaging fixes. The changelog explicitly names downstream pressure from Debian and MacPorts, and recent changes mention packager hardening flags, making it a clean example of a tiny utility shaped by distributions over decades.
