A community WASM plugin for proto that manages Composer versions.

Composer requires PHP. Install PHP via proto-php-plugin or have it available on your system PATH.

proto plugin add composer "github://KonstantinKai/proto-composer-plugin"
proto install composer

# Install Composer
proto install composer 2.8

# Use Composer
proto run composer -- --version

# List available versions
proto versions composer

# Pin a version in the current directory
proto pin composer 2.8

Configure in .prototools under [tools.composer]:

[tools.composer]
# Custom COMPOSER_HOME directory (optional)
composer-home = "/path/to/composer/home"

Unlike most proto plugins that download prebuilt native binaries, Composer is distributed as a PHP archive (PHAR). The plugin uses native_install to:

1. Download composer.phar from getcomposer.org/download/<version>/composer.phar
2. On Unix: save as composer and chmod +x
3. On Windows: save as composer.phar and create a composer.bat wrapper

The plugin declares requires: ["php"] so proto ensures PHP is available before installing Composer.

• latest — resolves to the newest stable Composer 2.x release
• stable / lts — same as latest
• Partial versions like 2.8 resolve to the latest patch (e.g. 2.8.6)

• proto-php-plugin — PHP version management for proto
