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. ### 时间线 - 2013: Public tag 0.2.0 was created in December 2013. - 2014: FreeBSD's ports tree added textproc/libucl in November 2014. - 2015: Public tag 0.7.2 was created in February 2015. - 2023: GitHub releases page lists libucl 0.8.2 on January 8, 2023. - 2024: GitHub releases page lists libucl 0.9.0 on February 1, 2024. ### Related projects -
