プロジェクトの歴史

The GitHub repository was created in April 2021. The project developed as a standalone binary with a dedicated site at jless.io and a mascot/logo identity, while its user guide expanded beyond simple viewing into navigation, search, copying, printing, YAML handling, and newline-delimited JSON support.

The release stream visible in the repository tags includes 0.7.x through 0.9.0, with the 0.9.0 GitHub release adding line numbers, deeper collapse and expand commands, print commands, and search/scrolling fixes.

採用の歴史

The input package metadata records `jless` in Homebrew, MacPorts, Nix, apk, pacman, and zypper. The project README also lists Homebrew, MacPorts, Arch, Void, NetBSD, FreeBSD, Cargo, and prebuilt release binaries, showing the package fits the common 'single fast CLI binary' distribution pattern.

使われ方

`jless` reads JSON from files or standard input, including data piped from APIs, `jq`, or log streams. It focuses on interactive exploration: users expand and collapse objects, move with vim-inspired commands, search across pretty-formatted data, copy JSON paths or values, and switch between data and line display modes.

The user guide also documents YAML input and newline-delimited JSON, which makes the tool useful for structured logs and command-line data inspection beyond one-off pretty printing.

パッケージ好きにとっての重要性

`jless` occupies a recognizable niche in the terminal data-toolchain: it is less a transformer like `jq` and more an interactive pager specialized for structured data. That makes it attractive for package collections because it pairs well with curl, `jq`, logs, and API debugging without requiring a language runtime at use time.

タイムライン

• 2021: The GitHub repository is created.
• 2023: Release v0.9.0 adds line numbers, print commands, deeper collapse and expand commands, and several interaction fixes.
• 2023: The README documents distribution through multiple OS package managers plus Cargo and prebuilt binaries.

Related projects

• The README explicitly names `less`, `jq`, `cat`, and editors as tools `jless` can replace for viewing JSON. The user guide also documents interoperability with `jq` output and refers to the Rust regex engine used for searching.
