alder

Alder is a command‑line utility that prints a recursive listing of a directory tree, similar to the traditional UNIX `tree` command, but with additional options for colorized output, file‑size reporting, and timestamps. It can filter entries using regular‑expression include and exclude patterns, honor `.gitignore` rules, and optionally show only directories or prune empty folders. Users can limit the depth of recursion, control indentation, and request full path prefixes, making it suitable for quick visual inspection of project structures.

The tool is installed globally via package managers such as Yarn or npm, and it runs on any system where Node.js is available. Its interface follows common CLI conventions, offering flags like `-a` to show hidden files, `-s` to display sizes, and `-t` for modification dates. An optional JSX output mode allows the tree to be emitted as a React‑compatible structure.

Alder targets developers and system administrators who need a lightweight, configurable way to explore file hierarchies from the terminal without the overhead of full‑featured file managers. Its stable release status indicates readiness for production use.
