问题 I am now implementing themes in my project. I have installed igaster/laravel-theme package. While I can switch themes by changing the default theme in config/themes.php, I have no idea how to change a theme sitewide - with a button like this: <a href="set_theme/2">change to 2</a>. The package's author says I need to use a ServiceProvide. I created one. And now... what? Edit: solution Based on the answer provided by igaster I made it work - PARTIALLY.

Register a package service provider from within that package

阅读更多关于 Register a package service provider from within that package

In all Laravel versions, if we want to register a new service provider, we can open the config/app.php file and add the new provider to the providers array, like so: 'providers' => [ ... Path\To\New\ServiceProvider::class, ], My idea is to install a package and have it automatically load its service provider, so without a need to add the new provider to the Laravel's app.php I have two questions: Is this a good idea? In both cases, why is it good / not good? Is there a preferred way of doing this? My guess is to autoload a bootstrap file from the package's composer.json , and then $this->app-

MarkupExtension.ProvideValue — Is the IServiceProvider actually used?

阅读更多关于 MarkupExtension.ProvideValue — Is the IServiceProvider actually used?

问题 I was going through some old code of mine and came across a hybrid IValueConverter / MarkupExtension class. It got me wondering if the IServiceProvider in the ProvideValue method was actually useful, and how it would be useful? I see that IServiceProvider only has one method: GetService , which must be cast to the proper service type. I also looked at the MarkupExtension.ProvideValue MSDN page and it lists different types of services. I guess, I'm just wondering if any of those services are

Defining a SPI in Clojure

阅读更多关于 Defining a SPI in Clojure

问题 I'm looking for an idiomatic way(s) to define an interface in Clojure that can be implemented by an external "service provider". My application would locate and instantiate the service provider module at runtime and delegate certain responsibilities to it. Let's say, for example, that I'm implementing a RPC mechanism and I want to allow a custom middleware to be injected at configuration time. This middleware could pre-process the message, discard messages, wrap the message handler with

Understanding the concept behind Service provider framework like JDBC using the factory method

阅读更多关于 Understanding the concept behind Service provider framework like JDBC using the factory method

From Effective Java ( Item 1 : Consider static factory methods instead of constructors ): The class of the object returned by a static factory method need not even exist at the time the class containing the method is written. Such flexible static factory methods form the basis of service provider frameworks, such as the Java Database Connectivity API (JDBC). A service provider framework is a system in which multiple service providers implement a service, and the system makes the implementations available to its clients, decoupling them from the implementations.
