aperçu
JSON output from a shell
historique
jo is a small C command-line utility for producing JSON from shell arguments or standard input. Jan-Piet Mens introduced it in March 2016 as a response to the awkwardness of hand-writing JSON in shell scripts, and the repository describes it plainly as JSON output from a shell.
The GitHub repository was created on March 4, 2016, and Jan-Piet Mens published a companion article on March 5 explaining the motivation: producing valid JSON from shell scripts becomes hard once quoting, variables, and embedded strings enter the picture. The early 0.x releases followed within days, and 1.0 arrived on March 11, 2016.
The changelog shows a project that grew carefully around shell ergonomics: nested elements, pretty printing, booleans, file inclusion, OpenBSD pledge support, type coercion, object paths, Docker support, array reading, zsh completion, Meson support, and fixes for Windows and long-line stdin handling.
jo spread through package managers because it solves a narrow shell-scripting pain point without pulling in a large runtime. Its README lists Homebrew, MacPorts, Ubuntu, Gentoo, Fedora, Snap, Scoop, AIX, Void Linux, Arch, OpenBSD, FreeBSD, Guix, pkgsrc, Repology, and Docker as distribution routes or related package entries.
Users call jo with key=value words to emit JSON objects, use -a for arrays, -p for pretty output, and type prefixes or special value forms when they need stronger control over numbers, booleans, nulls, file contents, or nested data. It is commonly paired with shell scripts, HTTP clients, monitoring hooks, and other command-line pipelines.
jo is package-nerd significant because it is the Unix philosophy version of JSON generation: small, composable, scriptable, packaged almost everywhere, and complementary to jq. It sits in the gap between fragile echo/printf JSON and starting a Python, Ruby, Node, or jq program just to build an object.
