Description:

shadertoy sqlite

shadertoy_sqlite #
A shadertoy storage implementation on sqlite using the drift package




Overview #
This package implements the storage APIs defined in the shadertoy package on sqlite through the drift package
Getting Started #
Add shadertoy_sqlite to your pubspec.yaml replacing x.x.x with the latest version available:
dependencies:
shadertoy_sqlite: ^x.x.x

Run the following command to install dependencies:
dart pub get

Finally, to start developing import the library:
import 'package:shadertoy_sqlite/shadertoy_sqlite.dart';
copied to clipboard
Usage #
To create a new store the ShadertoyStore implementation needs to be instanciated. The example bellow creates a new drift store with an in memory implementation (mostly used for test purposes)
final store = newShadertoySqliteStore(VmDatabase.memory(logStatements: logStatements));
copied to clipboard
A more real example would entail de creation of a database backed by a file like so:
final store = newShadertoyDriftStore(VmDatabase(File('shadertoy.db')))
copied to clipboard
This allows the execution of persistent operations, for example storing the definition of a shader with:
final shader = Shader(...);
final ssr = await store.saveShader(shader);
if (ssr.ok) {
print('Shader stored');
} else {
print('Error: ${response.error.message}')
}

A more complete example bellow:
import 'package:drift/ffi.dart';
import 'package:drift/drift.dart';
import 'package:shadertoy/shadertoy_api.dart';
import 'package:shadertoy_sqlite/shadertoy_sqlite.dart';

// In-memory executor
QueryExecutor memoryExecutor({bool logStatements = false}) {
return VmDatabase.memory(logStatements: logStatements);
}

// File executor
QueryExecutor diskExecutor({bool logStatements = false}) {
return VmDatabase(File('shadertoy.db'), logStatements: logStatements);
}

void main(List<String> arguments) async {
// Creates a new store with an in-memory executor
final store = newShadertoySqliteStore(memoryExecutor());

// Creates user 1
final userId1 = 'UzZ0Z1';
final user1 =
User(id: userId1, about: 'About user 1', memberSince: DateTime.now());
await store.saveUser(user1);

// Retrieves user 1
await store.findUserById(userId1);

// Creates user 2
final userId2 = 'UzZ0Z2';
final user2 =
User(id: userId2, about: 'About user 2', memberSince: DateTime.now());
await store.saveUser(user2);

// Retrieves user 2
await store.findUserById(userId2);

// Creates a shader with two render passes
final shaderId1 = 'SzZ0Zz';
