## 项目历史与用法

unum is a small Fourmilab command-line utility for interconverting decimal, octal, hexadecimal, binary, Unicode character data, and HTML/XHTML named or numeric character entities. Its history is tied less to a large ecosystem than to the long Unix tradition of keeping compact text and lookup tools on the command line.

### 项目历史

John Walker published the Fourmilab unum page in February 2006. The page presents unum as a standalone portable Perl program that removes the need to manually consult Unicode tables, HTML entity references, and programmer calculators when preparing web documents or source text.

The utility remained maintained as Unicode and HTML entity data changed. The Fourmilab page lists multiple updates from 2017 through 2023 and identifies version 3.6-15.1.0 as released on October 21, 2023, with character tables based on Unicode 15.1.0.

### 采用历史

unum appears in Homebrew as a niche developer utility rather than a broad platform tool. Its adoption story is mostly the durable packaging of a single-file Perl reference program for users who want Unicode and entity lookups available from a shell.

### 使用方式

The tool is used to answer questions such as converting code points between bases, finding the Unicode name for a character, looking up HTML entities, decoding UTF-8 byte sequences, and listing Unicode blocks. Fourmilab documents installation as placing the single unum.pl file somewhere on PATH, with Perl and optionally bunzip2 as the main runtime requirements.

### 为什么软件包爱好者会关心

For package-nerd workflows, unum is the kind of low-dependency utility that survives because it is scriptable, portable, and focused. It is useful when packaging documentation, terminals, web pages, or source files expose encoding details that are easier to inspect from a CLI than from a browser or GUI character map.

### 时间线

- 2006: Fourmilab page published for unum.
- 2017-2023: Fourmilab page records periodic updates.
- 2023: Version 3.6-15.1.0 released with Unicode 15.1.0 tables.

### Related projects

- Fourmilab documents unum alongside Unicode, HTML/XHTML character references, Perl, and W3C HTML entity data rather than as part of a larger suite.
