Composer Suites

Generates multiple variations of the original composer.json

1. You have to define the differences in the composer.json#/extra/composer-suite, see the examples below.
2. Next step is to generate the alternative composer.json files by running the following command:
   composer -vv suite:generate
3. Activate one of the alternative composer.json file by setting the COMPOSER environment variable.
   1. export COMPOSER='composer.my-suite-01.json'
   2. composer update --lock

Other benefit is that, if there is any relative path in the composer.json – for example under the #/repositories/FOO/url or anywhere under the #/extra – then those paths will work with the alternative composer.*.json files as well.

Example composer.json - multi-version dependency

    "require": {
        "symfony/console": "^4.0 || ^5.0",
        "symfony/process": "^4.0 || ^5.0"
    },
    "require-dev": {
        "phpunit/phpunit": "^8.0"
    },
    "scripts": {
        "test": "phpunit"
    },

                                }
                            }
                        }
                    }

                ]
            }
        }
    }
}

Run: composer suite:generate
The generated files:
composer.symfony4.json

{
    "require": {
        "symfony/console": "^4.0",
        "symfony/process": "^4.0"
    },
    "require-dev": {
        "phpunit/phpunit": "^8.0"
    },
    "scripts": {
        "test": "phpunit"
    },
    "extra": {}
}

composer.symfony5.json

{
    "require": {
        "symfony/console": "^5.0",
        "symfony/process": "^5.0"

Then

unset COMPOSER
composer update --lock
composer suite:generate

export COMPOSER='composer.symfony4.json'
composer update
composer run test

export COMPOSER='composer.symfony5.json'
composer update
composer run test

# Back to normal.
unset COMPOSER
composer update --lock

Use case

A certain third-party service has to be integrated into a framework.

Composer packages:

• RestAPI client (type: library)
• module/plugin for the framework (type: library)
• the framework (type: project)

{
    "type": "project",
    "repositories": {},
    "require": {
        "my/module_01": "^1.0"
    },
    "require-dev": {
        "sweetchuck/composer-suite": "^1.0"
    },
    "extra": {
        "composer-suite": {
            "local": {
                "description": "Local development",
                "actions": [

                            "parents": ["repositories"],
                            "items": {
                                "my/module_01": {

                                        }
                                    }
                                }
                            }
                        }
                    },
                    {
                        "type": "replaceRecursive",
                        "config": {
                            "parents": ["require"],
                            "items": {
                                "my/module_01": "1.x-dev",

                            }
                        }
                    }
                ]
            }
        }
    }
}

Run: composer suite:generate
The generated file:
composer.local.json

{
    "type": "project",
    "repositories": {
        "my/module_01": {
            "type": "path",
            "url": "../../my/module_01-1.x",
            "options": {
                "repo-path": {
                    "url": "https://github.com/my/module_01.git",
                    "branch": "1.x"
                }
            }
        },
        "my/restapi_client_01": {
            "type": "path",

            "options": {
                "repo-path": {
                    "url": "https://github.com/my/restapi_client_01.git",
                    "branch": "1.x"
                }
            }
        }
    },
    "require": {
        "my/module_01": "1.x-dev",
        "my/restapi_client_01": "1.x-dev"
    },
    "require-dev": {
        "sweetchuck/composer-suite": "^1.0"
    },
    "extra": {}
}

Then

unset COMPOSER
composer update --lock
composer suite:generate

cp ./composer.lock ./composer.local.lock
export COMPOSER='composer.local.json'
composer update --lock

# You can work on both libraries (restapi_client_01 and module_01) on-the-fly.

# Back to normal.
unset COMPOSER
composer update --lock

Suites

You can have as many suites as many you want.

As the examples above show that, suites can be defined in the composer.json#/extra/composer-suite, but suite definitions can be stored in external files as well.
./.composer-suite/composer-suite.*.json. Then it is up to you if these files will be tracked by the VCS or not.

Example ./.composer-suite/composer-suite.foo.json:

{
    "name": "foo",
    "description": "My foo suite.",
    "actions": []
}

The name key is optional. If it is omitted then, the suite name will be parsed from the file name.

If two suites have the same name, then the one which comes from external file, has the highest priority.

Actions

You can define different array manipulation actions under the extra/composer-suite/<suite-id> keys.

An action has two main properties:

• type (string) Identifier of the action.
• config (mixed) The data type is usually array, but it depends on the type.

Action - replaceRecursive

Official PHP documentation: array_replace_recursive()

• parents: array
• items: array

{
    "require": {
        "a/b": "^1.0",
        "symfony/console": "^4.0",
        "symfony/process": "^4.0"
    },
    "extra": {
        "composer-suite": {
            "my-suite-01": {
                "actions": {
                    "type": " replaceRecursive",
                    "config": {
                        "parents": [],
                        "items": {
                            "require": {
                                "symfony/console": "^5.0",
                                "symfony/process": "^5.0"
                            }
                        }
                    }
                }
            }
        }
    }
}

Result:

{
    "require": {
        "a/b": "^1.0",
        "symfony/console": "^5.0",
        "symfony/process": "^5.0"
    },
    "extra": {}
}

Action - unset

Removes the specified elements.

• parents: array

{
    "name": "a/b",
    "foo": {
        "bar": "delete me"
    },
    "extra": {
        "composer-suite": {
            "my-suite-01": {
                "actions": {
                    "type": "unset",
                    "config": {
                        "parents": [
                            "foo",
                            "bar"
                        ]
                    }
                }
            }
        }
    }
}

Result:

{
    "name": "a/b",
    "foo": {},
    "extra": {}
}

In the "config.parents" array the last item can be an array:

{
    "name": "a/b",
    "foo": {
        "a": "delete me 1",
        "b": "keep me",
        "c": "delete me 2"
    },
    "extra": {
        "composer-suite": {
            "my-suite-01": {
                "actions": {
                    "type": "unset",
                    "config": {
                        "parents": [
                            "foo",
                            [
                                "a",
                                "c"
                            ]
                        ]
                    }
                }
            }
        }
    }
}

Result:

{
    "name": "a/b",
    "foo": {
        "b": "keep me"
    },
    "extra": {}
}

Action - prepend

• items: array

Commands

This Composer plugin defines the following commands:

• composer suite:list
• composer suite:generate

Validate

You can check the status of the autogenerated files by running the official COMPOSER='composer.json' composer validate command.
If one of the autogenerated file is exists AND out-of-date, then the exit code will be other than 0.
This command does not report any problem about the missing composer.*.json files.
