README

A no-frills PsySH-Composer plugin.

In a nutshell, it provides a composer shell subcommand that spawns a Psy Shell with autoload integration when applicable.

Installation

This package is meant to be used as a global requirement for your Composer installation:

$ composer global require uma/composer-psysh

Alternatively it can be required on a per-project basis as a development dependency. Note that in this case the shell subcommand will only be available in the project root.

$ composer require --dev uma/composer-psysh

Composer 2.2 and above

Starting from version 2.2.0 Composer requires plugins to be whitelisted in the composer.json file. After updating to +2.2, the first time you run composer shell it will ask you once if you want to add the plugin to the allow-plugins config section. You'll need to answer Yes.

$ composer shell
uma/composer-psysh contains a Composer plugin which is currently not in your allow-plugins config. See https://getcomposer.org/allow-plugins

Usage

composer psy can be run anywhere and will spawn a generic REPL. However, when it runs at the root of a project it will require the vendor/autoload.php script so that the project's classes will be readily available in the shell.

The plugin also defines a couple other aliases: composer repl and composer psy.

Comparison between uma/composer-psysh and ramsey/composer-repl

This package was inspired by ramsey/composer-repl. In fact, it only provides a subset of its features. I decided to write my own version for a couple of reasons:

First, Ben Ramsey's plugin requires PHP 7.4 or later, which is too restrictive for me. uma/composer-psysh allows a wide range of PHP versions: from 5.5 to 8.1. This is pretty similar to the range of versions allowed by PsySH and Composer themselves.

Second, ramsey/composer-repl has additional functionality to integrate PHPUnit into PsySH. Because of this it has a hard dependency on phpunit/phpunit. I wasn't keen on being forced to pull PHPUnit alongside the plugin, especially since I don't need that feature.

Caveats

Only works on Unix environments (for now?)
