A new project for a new year

As the year and decade wrap up, we have some exciting news: we've just completed migrating the Zend Framework code to the various Laminas projects!

Current Status

There's still work to be done, but the actual code migration is complete! You can find the code in the following locations:

We still have a few things to iron out:

~~The Packagist API, while it claimed to work and did not return errors, did not always abandon the old packages; we'll be auditing those later this week.~~
~~We will be renaming our Slack workspace later this week to reflect the change.~~
~~Likewise, we'll be renaming our Discourse and re-pointing it.~~
Our bot will need some changes to work with the new repos, and we will likely be moving tasks such as building documentation to GitHub Actions. (Update: documentation is now built via GitHub Actions.)
We need to rebuild the former Apigility site to reflect the name change, and plan to eventually push it to api-tools.getlaminas.org.
We need to update the Zend Framework, Apigility, and Expressive websites to indicate the changes.

But the hard part is now done, and you can start using the code TODAY!

Speaking of...

How to migrate to Laminas

If you run a ZF MVC, Apigility, or Expressive application, or even just use any Zend Framework, Apigility, or Expressive components in your application, we have a tool that will help you migrate.

Regardless of your scenario, use the following steps.

0. Ensure you have an up-to-date Composer

Due to features of Composer our dependency plugin uses, we require Composer 1.7.0 and up. If you're unsure what version you are on, run composer --version. If you are on an older version, run composer self-update, or install from scratch.

1. Install laminas-migration

To migrate a project, first install the laminas/laminas-migration package.

Via Composer

Install the library globally using Composer:

$ composer global require laminas/laminas-migration

If you choose this option, you will need to ensure that the vendor/bin/ subdirectory of your > global Composer installation is in your environment $PATH.

You can find where the global Composer installation is by executing:

$ composer global config home

On Linux and Mac operating systems, update your shell configuration to add that path to your $PATH environment variable.

Adding to the PATH

The mechanism for adding to your environment $PATH variable depends on your operating system.

For Linux, Mac, and other *nix variants, you can do so by adding a line like the following at the end of your profile configuration file (e.g., $HOME/.bashrc, $HOME/.zshrc, $HOME/.profile, etc.):
$ export PATH={path to add}:$PATH
For Windows, the situation is a bit more involved; this HOWTO provides a good tutorial on the subject.

Via cloning

Clone the repository somewhere:

$ git clone https://github.com/laminas/laminas-migration.git

Install dependencies:

$ cd laminas-migration
$ composer install

From there, either add the bin/ directory to your $PATH (see the note on adding to the PATH, above), symlink the bin/laminas-migration script to a directory in your $PATH, or create an alias to the bin/laminas-migration script using your shell:

# Adding to PATH:
$ export PATH=/path/to/laminas-migration/bin:$PATH
# Symlinking to a directory in your PATH:
$ cd $HOME/bin && ln -s /path/to/laminas-migration/bin/laminas-migration .
# creating an alias:
$ alias laminas-migration=/path/to/laminas-migration/bin/laminas-migration

2. Run the migration command

From there, enter a project you wish to migrate, and run the following:

$ laminas-migration migrate

You may want to use the --exclude or -e option one or more times for directories to exclude from the rewrite; on the ZF website and my own, I used -e data, for instance:

$ laminas-migration migrate -e data

Module and Config Post Processor injection

If you are migrating an MVC, Apigility, or Expressive application, the migration tooling attempts to inject some code in your application. This can fail if you have non-standard configuration.

For MVC and Apigility applications, the migration tooling attempts to add Laminas\ZendFrameworkBridge as a module to the top of the config/modules.config.php file. If injection fails, add the module in a way appropriate to your application.

For Expressive applications, the migration tooling attempts to add Laminas\ZendFrameworkBridge\ConfigPostProcessor as a post processor class to the ConfigAggregator constructor. The ConfigAggregator constructor has the following signature:
public function __construct(
    array $providers = [],
    ?string $cachedConfigFile = null,
    array $postProcessors = []
)
Typically, the structure of the config/config.php file in an Expressive application looks like the following:
$cacheConfig = [
    'config_cache_path' => 'data/cache/app_config.php',
];

$aggregator = new ConfigAggregator([
    // config providers from 3rd party code
    // ...

    // App-specific modules
    // ...

    // Include cache configuration
    new ArrayProvider($cacheConfig),

    // Load application config in a pre-defined order in such a way that local settings
    // overwrite global settings. (Loaded as first to last):
    //   - `global.php`
    //   - `*.global.php`
    //   - `local.php`
    //   - `*.local.php`
    new PhpFileProvider('config/autoload/{{,*.}global,{,*.}local}.php'),

    // Load development config if it exists
    new PhpFileProvider('config/development.config.php'),
], $cacheConfig['config_cache_path']);

return $aggregator->getMergedConfig();
As such, the migration tooling rewrites the second to last line to read:
], $cacheConfig['config_cache_path'], [\Laminas\ZendFrameworkBridge\ConfigPostProcessor::class]);
In most cases, failure to inject means that the individual arguments have been pushed to their own line. In such cases, add the third argument as detailed above.

In other cases, applications may already be using post processors. If so, add \Laminas\ZendFrameworkBridge\ConfigPostProcessor::class to the list of post processors.

3. Install dependencies

Once migration is done and you've added the repository, you can install dependencies:

$ composer install

From there, run tests, and report any issues to the Laminas slack in the #laminas-issues channel, or report directly in the appropriate issue trackers, based on the components in which you see problems.

(These instructions are now on the documentation site

What's next?

As outlined above, we have a number of things to do to finish up the migration. Additionally:

We are completing our technical charter with the Linux Foundation.
We will be starting a Community Bridge campaign to raise some initial finances.
We want to complete our API story for Mezzio.
We have more async integrations we want to do.
And, of course, projects to finish, such as separating out adapters from components like laminas-cache and laminas-db, PSR-7 integration in the MVC, and more.

Stay tuned for more announcements, and Happy New Year! Let's build great things this next year and decade!
