Runs all codegen tasks for any extension on any resource/domain in your application.

Flags

• --dry-run - no files are created, instead the new generated code is printed to the console
• --check - no files are created, returns an exit(1) code if any code would need to be generated
• --dev - runs codegen tasks in dev mode. See the section on dev mode below
• Individual extensions may use additional flags.

Dev Mode

Some extensions that do codegen require providing a name. Those extensions (should) support a --dev flag, which indicates that the codegen can have a temporary name chosen by the extension. Then, once you are ready to commit the changes, you can run the codegen tasks again without the --dev flag and with a name to generate the final code.

For example, using AshPostgres:

• First we add first_name to MyApp.Accounts.User
• mix ash.codegen --dev, which generates a migration for adding first_name to the "users" table, but the migration is suffixed with _dev
• mix ash.migrate apply the migrations
• Then we add last_name to MyApp.Accounts.User
• mix ash.codegen --dev which generates a migration for adding last_name to the "users" table, but the migration is suffixed with _dev
• We review our changes, and are ready to save them as a unit
• mix ash.codegen add_name_to_user, which rolls back and deletes the dev migrations & snapshots, and creates new ones using the provided name
