软件包摘要
Universal configuration library parser
历史
项目历史与用法
libucl is Vsevolod Stakhov's C library for Universal Configuration Language, a configuration syntax designed to be easier for humans to edit than strict JSON while remaining machine-readable and JSON-compatible.
项目历史
The libucl README describes UCL as a configuration language heavily influenced by nginx-style configuration while remaining compatible with JSON. The library parses UCL and can also operate with JSON, MessagePack, S-expressions, and limited YAML output.
Public tags show early 0.2.x releases in December 2013 and 0.7.x by February 2015. After a long 0.8-era gap, GitHub releases show renewed release activity in 2023 and a 0.9 series beginning in February 2024.
采用历史
UCL found its strongest adoption in systems and infrastructure software where maintainers wanted structured configuration without strict JSON's editing friction. Rspamd documents UCL as its configuration language, and the FreeBSD Handbook notes that some applications such as pkg(8) started using UCL.
The library's package presence across Unix-like package managers reflects that adoption pattern: it is a small C parser and utility package that other software can embed or link for configuration parsing.
使用方式
Developers use libucl to parse configuration files with comments, unquoted keys, optional separators, implicit arrays, variables, macros, includes, human-friendly numeric suffixes, and validation. The README cautions that full-featured parsing with macros, includes, file I/O, and URL includes is intended for trusted administrator-controlled configuration rather than hostile input.
为什么软件包爱好者会关心
libucl is package-nerd interesting because it sits at the crossroads of config-language taste, Unix administration, FreeBSD tooling, and embeddable C libraries. It is a pragmatic alternative to forcing strict JSON into files humans edit by hand.
