It is best known in package culture through FreeBSD's structured-output work. ### Project history The project README explains the central idea: applications call xo_emit with field descriptors, and the selected output style is chosen at runtime. GitHub tag metadata places the 0.1.0 tag at a commit dated 2014-07-30. The FreeBSD manual page records Phil Shafer as author and says the library was added in FreeBSD 11.0. That adoption moved libxo from a standalone library into the base-system conversation about machine-readable command output. ### Adoption history FreeBSD's adoption gave libxo a practical audience: base utilities could keep human-readable output while adding JSON, XML, or HTML modes for scripts and automation. The package is also available outside FreeBSD for projects that want the same structured-output model. ### How it is used Users generally encounter libxo through commands that accept a libxo output mode or through the xo utility family. Developers use the library when they want one formatting path to serve terminal text and structured data consumers. ### Why package nerds care libxo matters because it is a concrete answer to the long-running Unix problem of parsing human text with fragile awk and sed pipelines. It represents the package-manager-adjacent push toward structured CLI output without abandoning traditional command output. ### Timeline - 2014: The 0.1.0 GitHub tag points to a commit dated 2014-07-30. - 2014: The FreeBSD Ports manual page date for libxo(3) is 2014-12-08. - 2016: FreeBSD 11.0 included libxo according to the FreeBSD manual page. - 2020s: libxo remains packaged for Homebrew, FreeBSD ports, and multiple Unix-like distributions. ### Related projects - FreeBSD base utilities are the most visible related ecosystem. jq and other JSON-processing tools are common downstream companions when libxo-enabled commands emit JSON. ### Sources - - - - - ## Security Notes library-like package without higher-risk signals. -
