This patch introduces a dependency injection container for the PHP bug
tracker application. Container deals with the creation of all service
classes and additionally provides retrieving of configuration parameters.
Service classes are used everywhere in the app - from accessing database
to uploading files. Configuration parameters include infrastructure
configuration (database credentials...) and application level
configuration (directories locations...).
Container is compatible with the PSR-11 container interface defined
so it is simple to quickly understand its usage. Advanced features
such as autowiring are not included in this phase.
This patch adds an initial simplistic template engine to separate logic
from the presentation.
Basic initial features:
- escaping via Context::noHtml() and Context::e() methods
- blocks
- nesting options using includes and extending layouts
- PHP syntax
- variable scopes dedicated to template scope only
- Appending blocks (when JS files are in need to be appended)
- initial unit and functional tests
- Main index page refactored as an example of usage
- Very short intro docs how to use the template layer
- Thanks to @nhlm for the code review and numerous suggestions to
improve the usability and code stability,
- Thanks to @KalleZ and for the code review and numerous common sense
suggestions about templates themselves.
- Thanks to @Maikuolan for the code review and numerous suggestions
about the usability.
- Moved hash ids redirection to aseparate JavaScript file
- Use location instead of window.location in the JavaScript redirection
