ivy-prompt

ivy-prompt

A line editor interface wrapper for Rob Pike's Ivy, an interpreter for an APL-like language. It provides a Readline-style input prompt with input history and tab-completion.

The original ivy command interacts with the world via standard input/output, integrating well with a Unix or Plan 9 environment or a text editor like Acme. However, if you prefer or are used to a mode of interaction more akin to Bash, Haskell's GHCi, or Python's REPL with an interactive line editor, then this project is for you.

Although Ivy is described by its creator as "a plaything," it should not be underestimated. Watch Russ Cox' videos of solutions for Advent of Code 2021 using Ivy for a demonstration of its capabilities or take the built-in tour with the )demo command.

Installation

First install Ivy itself, if you haven't already done so:

go install robpike.io/ivy@latest    # or @master if you want to use
                                    # the development version of Ivy.

The ivy binary should be in the PATH.

Then install this wrapper:

go install github.com/fzipp/ivy-prompt@latest

Run it:

ivy-prompt
