lippy

lippy is a small scripting language for the shell — the jobs you'd reach for bash or a bit of Python to do, written in a way that reads like plain English and starts before other languages have finished waking up.

# services.lip — is anything down?
for name in ["gitea", "kavita", "jellyfin"]
    # attempt lets a request fail without stopping the script
    result is attempt fetch("http://localhost/health/{name}")
    if ok of result then
        say "{name} ok"
    else
        say "{name} is DOWN"
    end
end

Why you might like it

• Reads like English. greater than, and, not, then, end — not >, &&, !, {, }.
• Errors that help. They say what went wrong, where, and what you probably meant.
• One static binary. No runtime, no packages to install. Copy it and run.
• Batteries included. JSON, YAML, CSV, markdown, HTTP (client and a tiny serve), SQLite and MySQL/MariaDB, dates, patterns — all in the box.
• Safe by default. Values handed to a shell command or a database query can never split into new arguments or become SQL. Injection isn't a footgun you have to remember.

Get going

Install it with the one-liner above (Linux and macOS) or the PowerShell one (Windows), then:

lippy eval "2 + 3 * 4"
lippy eval 'say "hello, {upper("world")}"'

Write a script, put #!/usr/bin/env lippy at the top, chmod +x it, and it's a command. Read the Guide for the whole tour, or the Syntax, Types, and Errors notes for the details.
