drush

Drush 9 has removed dynamic site aliases. Site aliases are hardcoded in YAML files rather than declared in PHP. Sadly, that means that many tricks you could do with the declaration of the site aliases are no longer available.

The only grouping possible is based on the YAML filename. So for example, with the Acquia Cloud Site Factory site aliases generated by the 'blt recipes:aliases:init:acquia' command, you can run a command on the same site across different environments.

But what you can't do is run a command on all the sites in one environment.

Okay, so I lied. But module builder can save you a lot of time when writing custom modules.

And it now works with drush, too. I added support for drush a few weeks ago, which let you do things like "$ drush mb mymodule cron init menu nodeapi --write" and hey presto, a new module folder is created, with an info file and a module file, with hook implementations ready to do your (evil) bidding. (Note: this blog does not sanction use of Drupal, module builder, or drush for evil.)
