Code Injector

Changelog

Request parameters are read with Piwik\Request instead of the deprecated Common::getRequestVar, ready for the next Matomo versions.

Requires Matomo 5.0.0 or higher (>=5.0.0,<6.0.0-b1). The code editor falls back to the Matomo light theme colors when the theme color variables are not available (before Matomo 5.10.0).
The code is edited on a dedicated Administration > System > Code Injector page instead of the General settings, existing code is kept
New CodeInjector.getCode and CodeInjector.setCode API methods (super user only, saving requires the password confirmation)
Code editor with HTML, CSS and JavaScript syntax highlighting, in a light and dark palette that follows the Matomo theme
Live syntax checks: HTML, CSS, JavaScript and JSON-LD errors, unclosed <script> and <style> tags, code pasted without tags
The code is not injected on the Code Injector page, so a snippet breaking the interface can always be fixed
Interface translated into 12 languages
Shorter Marketplace description that fits the plugin cards, and campaign parameters on the Openmost links of the README.
README: the plugin description now shows in the Description tab of the Matomo Marketplace.
