What's this?

This package makes your Blazor apps display the source .razor file name that generated the HTML element under the mouse cursor when entering the Ctrl + Shift + F hotkeys.

1. Installation

1-a. for Blazor WebAssembly projects

1. Add the FindRazorSource.WebAssembly NuGet package to your Blazor WebAssembly project.

> dotnet add package FindRazorSource.WebAssembly

2. Add calling of the UseFindRazorSourceFile() extension method for WebAssemblyHostBuilder at the startup of your Blazor WebAssembly app.

// This is a "Program.cs" file of a Blazor Wasm app.
...
using FindRazorSourceFile.WebAssembly; // 👈 Open this namespace, and...
...
  public static async Task Main(string[] args)
  {
    var builder = WebAssemblyHostBuilder.CreateDefault(args);

    // 👇 Add this #if ~ #endif block.
#if DEBUG
    builder.UseFindRazorSourceFile();
#endif
    ...

1-b. for Blazor Server projects

1. Add the FindRazorSource.Server NuGet package to your Blazor Server project.

> dotnet add package FindRazorSource.Server

2. Add calling of the UseFindRazorSourceFile() extension method for IApplicationBuilder at the startup of your Blazor Server app.

// This is a "Startup.cs" file of a Blazor Server app.
...
using FindRazorSourceFile.Server; // 👈 Open this namespace, and...
...
  public void Configure(IApplicationBuilder app, ...)
  {
    if (env.IsDevelopment())
    {
      ...      
      app.UseFindRazorSourceFile(); // 👈 Add this line.
    }
    ...

1-c. for Blazor components library projects

What you have to do is just adding the FindRazorSource NuGet package to the library project.

> dotnet add package FindRazorSource

2. Usage

2-1. Entering the "Inspection Mode"

After installing FindReSource in your Blazor project, the Blazor app running in a web browser will respond to Ctrl + Shift + F keyboard shortcuts entering to "Inspection Mode".

When the app entered "Inspection Mode," the entire browser screen will dim.

In this state, when you moved the mouse cursor, the HTML element under the mouse cursor will be highlighted, and the tooltip that displayed the source .razor file name generated that HTML element will appear.

2-2. Entering the "Lock Mode"

When you click an HTML element during the "Inspection Mode", the application's state will enter the "Lock Mode".

During the "Lock Mode", hovering the mouse cursor over the other HTML elements will have no effects.

The highlighting of the HTML element and showing the tooltip will be maintained.

This mode will be helpful for you to selecting and copy to the clipboard the source .razor file name displayed on the tooltip.

2-3. Exit each mode

To escape from these modes, you can press the ESC key.

And also, the mouse click during the "Lock Mode" will exit that mode and return to "Inspection Mode".
