Firebreath Development Tutorial: Getting Started with C++109

Firebreath is a cross-platform C++ framework for developing plugins for web browsers. It allows developers to create plugins that can access the browser's DOM, manipulate the page content, and communicate with the browser's JavaScript engine. In this tutorial, we will walk you through the basics of Firebreath development, starting with the installation and setup process.

Prerequisites

Before you begin, you will need the following software installed on your system:* A C++ compiler (e.g., Visual Studio, Xcode, or Clang)
* CMake
* Firebreath

Installation and Setup

To install Firebreath, follow these steps:1. Download the latest Firebreath release from the official website.
2. Extract the downloaded archive to a convenient location on your system.
3. Open a command prompt or terminal window and navigate to the Firebreath directory.
4. Run the following command to configure Firebreath:
```
cmake -G "Visual Studio 16 2019" -DFIREBREATH_BUILD_EXAMPLES=ON -DFIREBREATH_BUILD_TESTS=OFF
```
5. Once the configuration is complete, run the following command to build Firebreath:
```
cmake --build .
```

Creating a New Plugin

To create a new Firebreath plugin, follow these steps:1. Create a new directory for your plugin.
2. In the plugin directory, create a new header file (.h) and a new implementation file (.cpp).
3. In the header file, include the necessary Firebreath headers and declare your plugin class. For example:
```cpp
#include
class MyPlugin : public FB::JSAPIPlugin
{
public:
MyPlugin(FB::BrowserHostPtr host);
~MyPlugin();
virtual FB::JSAPIPluginInfo GetPluginInfo() const;
virtual bool Initialize();
virtual bool Shutdown();
};
```
4. In the implementation file, implement the methods of your plugin class. For example:
```cpp
#include "MyPlugin.h"
MyPlugin::MyPlugin(FB::BrowserHostPtr host) : FB::JSAPIPlugin(host)
{
}
MyPlugin::~MyPlugin()
{
}
FB::JSAPIPluginInfo MyPlugin::GetPluginInfo() const
{
FB::JSAPIPluginInfo info;
= "MyPlugin";
= "1.0";
= "{00000000-0000-0000-0000-000000000000}";
return info;
}
bool MyPlugin::Initialize()
{
return true;
}
bool MyPlugin::Shutdown()
{
return true;
}
```
5. Register your plugin with Firebreath by adding the following line to your file:
```cmake
firebreath_plugin(MyPlugin)
```
6. Build your plugin by running the following command:
```
cmake --build .
```
7. Copy the built plugin to the plugins directory of your browser.

Testing Your Plugin

To test your plugin, open your browser and navigate to the following URL:```
about:plugins
```

You should see your plugin listed in the list of installed plugins.
