Jinja for Dart

Jinja server-side template engine port for Dart 2. Variables, expressions, control structures and template inheritance.

Breaking changes

Before object.field or object.method() expressions uses dart:mirrors methods.

import 'package:jinja/jinja.dart';

// ...

final env = Environment( /* ... */ );
final template = env.fromString('{{ users[0].name }}');

// ...

outStringSink.write(template.render(users: listOfUsers));
// outStringSink.write(template.renderMap({'users': listOfUsers}));

Now to access the fields and methods of the object, (except namespase, loop, self fields and methods), you need to import the get_field method from the package:jinja/get_field.dart file and pass it to the Environment constructor.
Or write and pass own method, like here.

import 'package:jinja/jinja.dart';

import 'package:jinja/get_field.dart' show getField;

// ...

final Environment = Environment(getField: getField, /* ... */ );
final template = env.fromString('{{ users[0].name }}');

// ...

outStringSink.write(template.render(users: listOfUsers));
// outStringSink.write(template.renderMap({'users': listOfUsers}));

Done

• Loaders
  • FileSystemLoader
  • MapLoader (DictLoader)
• Comments
• Variables
• Expressions: variables, literals, subscription, math, comparison, logic, tests, filters, calls
• Filters (not all, see here)
• Tests
• Statements
  • Filter
  • For (without recursive)
  • If
  • Set
  • Raw
  • Inlcude
  • Extends
  • Block

Example

Add package to your pubspec.yaml as a dependency

dependencies:
  jinja: ^0.2.0

Import library and use it:

import 'package:jinja/jinja.dart';

// code ...

final Environment = Environment(blockStart: '...');
final template = env.fromString('...source...');

outStringSink.write(template.render(key: value));
// outStringSink.write(template.renderMap({'key': value}));

Note

Why is this hack used?

In the final version for the production version, templates will be generated and the render function will have named parameters that are used in the template code.

• jinja_core - core, filters, tests, utils
• jinja_config - yaml based environment config
• jinja_ast - parsing
• jinja_nodes - render nodes
• jinja_generator - generate pure dart code from AST
