Understanding the Documentation Provider

Introduction

As developers, we often find ourselves working with complex SQL files, trying to understand the intricacies of the code. One of the most common challenges we face is understanding the meaning behind symbols and keywords in the code. In this article, we will explore how to extend the symbol documentation content displayed when hovering over elements in SQL files, providing a more comprehensive and informative experience for developers.

Understanding the Documentation Provider

Before we dive into extending the symbol documentation content, it's essential to understand the concept of a documentation provider. A documentation provider is a plugin that provides additional information about the code, such as documentation, type information, and more. In the context of SQL files, a documentation provider can provide information about the symbols and keywords used in the code.

Implementing a Documentation Provider

To implement a documentation provider, we need to create a class that implements the DocumentationProvider interface. This interface provides methods for getting the documentation content for a given symbol or keyword. Here's an example of how to implement a documentation provider for SQL files:

public class SqlDocumentationProvider implements DocumentationProvider {
    @Override
    public String getDocumentation(String symbol) {
        // Get the documentation content for the given symbol
        // This can be done by querying a database or a knowledge base
        String documentation = "This is the documentation content for the symbol " + symbol;
        return documentation;
    }

    @Override
    public String getDefinition(String symbol) {
        // Get the definition of the given symbol
        // This can be done by querying a database or a knowledge base
        String definition = "This is the definition of the symbol " + symbol;
        return definition;
    }
}

Registering the Documentation Provider

Once we have implemented the documentation provider, we need to register it with the IDE. This can be done by creating a plugin that registers the documentation provider with the IDE. Here's an example of how to register the documentation provider:

public class SqlPlugin implements Plugin {
    @Override
    public void registerComponents() {
        // Register the documentation provider
        DocumentationProvider provider = new SqlDocumentationProvider();
        DocumentationProviderRegistry.registerProvider(provider);
    }
}

Extending the Symbol Documentation Content

Now that we have implemented and registered the documentation provider, we can extend the symbol documentation content displayed when hovering over elements in SQL files. We can do this by overriding the getDocumentation method in the DocumentationProvider interface. Here's an example of how to extend the symbol documentation content:

public class SqlDocumentationProvider implements DocumentationProvider {
    @Override
    public String getDocumentation(String symbol) {
        // Get the documentation content for the given symbol
        // This can be done by querying a database or a knowledge base
        String documentation = "This is the documentation content for the symbol " + symbol;
        // Add a list of executable actions
        documentation += "\n\n**Executable Actions:**\n";
        documentation += "- Action 1: This is the first action\n";
        documentation += "- Action 2: This is the second action\n";
        // Add definition information
        documentation += "\n\n**Definition:**\n";
        documentation += "This is the definition of the symbol " + symbol;
        return documentation;
    }
}

Displaying the Extended Documentation Content

Now that we have extended the symbol documentation content, we need to display it when hovering over elements in SQL files. We can do this by overriding the getDocumentation method in the DocumentationProvider interface. Here's an example of how to display the extended documentation content:

public class SqlDocumentationProvider implements DocumentationProvider {
    @Override
    public String getDocumentation(String symbol) {
        // Get the documentation content for the given symbol
        // This can be done by querying a database or a knowledge base
        String documentation = "This is the documentation content for the symbol " + symbol;
        // Add a list of executable actions
        documentation += "\n\n**Executable Actions:**\n";
        documentation += "- Action 1: This is the first action\n";
        documentation += "- Action 2: This is the second action\n";
        // Add definition information
        documentation += "\n\n**Definition:**\n";
        documentation += "This is the definition of the symbol " + symbol;
        // Display the extended documentation content
        DocumentationDisplay.displayDocumentation(documentation);
        return documentation;
    }
}

Conclusion

In this article, we explored how to extend the symbol documentation content displayed when hovering over elements in SQL files. We implemented a documentation provider that provides additional information about the symbols and keywords used in the code. We also extended the symbol documentation content by adding a list of executable actions and definition information. Finally, we displayed the extended documentation content when hovering over elements in SQL files. By following the steps outlined in this article, developers can create a more comprehensive and informative experience for themselves and their team members.

Future Work

There are several areas where we can improve the documentation provider and the extended documentation content. Some potential areas for future work include:

Improving the documentation content: We can improve the documentation content by adding more information about the symbols and keywords used in the code.
Adding more executable actions: We can add more executable actions to the list of actions displayed in the documentation content.
Displaying the documentation content in a more user-friendly way: We can display the documentation content in a more user-friendly way by using a table or a list to display the information.
Integrating the documentation provider with other tools: We can integrate the documentation provider with other tools, such as a code editor or a version control system, to provide a more comprehensive and informative experience for developers.
