Command line tools for moor

Usage

If your app depends on moor_generator, you’re ready to use the CLI tool. In this article, we’ll use pub run ... to start the tool. If you’re using Flutter, you need to run flutter pub run .... In either case, the tool should be run from the same folder where you keep your pubspec.yaml.

Analyze

Runs moor’s analyzer and linter across all .moor files in your project.

$ pub run moor_generator analyze

WARNING: For file test/data/tables/tables.moor:
WARNING: line 38, column 28: This table has columns without default values, so defaults can't be used for insert.
   ╷
38 │ defaultConfig: INSERT INTO config DEFAULT VALUES;
   │                            ^^^^^^
   ╵
INFO: Found 1 errors or problems

Exits with error code 1 if any error was found.

Identify databases

This is more of a test command to verify that moor’s analyzer is working correctly. It will identify all databases or daos defined in your project.

$ pub run moor_generator identify-databases

Starting to scan in /home/simon/IdeaProjects/moor/moor...
INFO: example/example.dart has moor databases or daos: Database
INFO: lib/src/data/database.dart has moor databases or daos: AppDatabase
INFO: test/fake_db.dart has moor databases or daos: TodoDb, SomeDao

Schema tools

Export

This subcommand expects two paths, a Dart file and a target. The Dart file should contain exactly one class annotated with @UseMoor. Running the following command will export the database schema to json.

$ pub run moor_generator schema dump path/to/databases.dart schema.json

The generated file (schema.json in this case) contains information about all

• tables, including detailed information about columns
• triggers
• indices
• @create-queries from included moor files
• dependecies thereof

The schema format is still a work-in-progress and might change in the future.
