Head/tail for structured data
历史
headson is a Rust CLI and Python library that acts like head or tail for structured data. Its executable, `hson`, previews JSON, YAML, text, and source files while respecting byte, character, or line budgets.
The GitHub repository was created in October 2025. The README frames the project as a structure-aware alternative to head and tail for JSON and YAML, later extended to text and source-code summaries.
Early releases moved quickly through core CLI capabilities: multiple input files, global character limits, tail sampling, color output, YAML loading, auto format detection, grep-like inclusion, tree-style multi-file previews, and source-code heuristics. The release log shows the project settling on `headson` as the package name and `hson` as the installed command.
Public adoption evidence is thin because the project is young and niche. Its upstream metadata, docs.rs page, and Homebrew formula show the intended audience: CLI users, shell scripts, and AI-agent or developer-tool workflows that need small previews of large structured files.
The package fills a modern command-line gap: traditional head and tail are line-oriented, while JSON and YAML often need tree-aware truncation to remain understandable after sampling.
A common use is piping JSON to `hson -c 800` to get a compact preview under a strict byte budget. Other examples include previewing many JSON files with a global budget, rendering strict JSON, showing YAML with comments, preserving grep matches under tight budgets, and summarizing source files by indentation-aware outlines.
The tool can read stdin or file paths, recurse through directories, respect git-aware ordering for multi-file summaries, and expose the same functionality as a Python library.
headson is interesting to package nerds because it is a tiny Rust CLI that wraps a very specific terminal workflow: inspect enough of a structured file without dumping the whole thing. It is especially suited to package-manager installs because users expect small inspection tools to be globally available on PATH.
It also reflects a newer CLI niche shaped by large logs, machine-readable APIs, and AI-agent context budgets: budgeted previews are no longer just cosmetic, they are part of keeping command output useful.
