README

pi-ilo-lang

A Pi extension for the ilo programming language.

Gives the pi coding agent two tools and the ilo skill so it can write ilo code and run it without shelling out.

Install

pi install npm:pi-ilo-lang

The extension calls the ilo binary on PATH. Install it first with the project install script or via npm i -g ilo-lang.

Tools

ilo_run

Run a program. Pass either inline source (code) or a file path (file). Optionally invoke a specific function with func and pass args.

ilo_run({ code: "double n:int >int;*n 2", func: "double", args: ["21"] })

Returns stdout, stderr, and the exit code.

ilo_repl

Hold an interactive ilo serv session. The session auto-closes after 5 minutes of inactivity.

ilo_repl({ command: "start" })
ilo_repl({ command: "send", program: "double n:int >int;*n 2", func: "double", args: ["21"] })
ilo_repl({ command: "stop" })

send writes one JSON request to the running session and returns the matching response line, per the ilo serv protocol.

Skill

Ships the ilo skill at skills/ilo/SKILL.md. Pi loads it automatically so the agent knows the syntax before reaching for the tools.

Configuration

  • ILO_BIN env var: absolute path to a specific ilo binary. Useful when running a development build.
