# Verify execution count.

The next code cell should have empty square brackets on the left, e.g., "`[ ]`".  Execute the cell and upon completion there should be a number there; probably "`[1]`".  Execute the cell again and verify that the number in the brackets increments by one, e.g., "`[2]`".

#!csharp

1+1

#!markdown

# Verify Completions.
The next code cell contains the code `Console`. At the end type, `.`. The completions list with properties and methods should be displayed.

#!csharp

Console

#!markdown

# Execute the following cell.

You'll notice a counter that appears and starts incrementing.  After a second or two, stop the cell.  Your output should look similar to:

```
5
Command cancelled
```

N.b., the old values (e.g., `1`, `2`, `3`, `4`, etc.) should no longer be displayed, but overwritten.

#!csharp

using System.Threading.Tasks;
using Microsoft.DotNet.Interactive;

var output = string.Empty.Display("text/plain");
var counter = 1;
while (!KernelInvocationContext.Current.CancellationToken.IsCancellationRequested)
{
    await Task.Delay(500, KernelInvocationContext.Current.CancellationToken);
    output.Update($"{counter++}");
}

#!markdown

# Execute the next two cells.

#!csharp

var x = 123;

#!html

<div id="output">The value is not yet set.</div>

#!markdown

# Execute the next two cells.  After execution, the output immediately above each should read:

```
The value is 123.
```

And the output below the next cell should display the same value.

#!javascript

#!share --from csharp x
document.getElementById("output").innerText = `The value is ${x}.`;
console.log(`The value is ${x}.`);

#!javascript

#!set --value @csharp:x --name y
y++;
document.getElementById("output").innerText = `The value is ${y}.`;
console.log(`The value is ${y}.`);

#!markdown

# Execute the next cell. After execution, the output immediately below should be:

```
javascript
```

#!javascript

const jsKernel = kernel.root.findKernelByName('javascript');
console.log(jsKernel.name);

#!markdown

# Execute the next cell. After execution, the output immediately below should be:

```
[".NET","csharp","fsharp","html","http","javascript","kql","mermaid","pwsh","sql","value","webview"]
```

#!javascript

kernels = Array.from(kernel.root.findKernels(s => true).map(k => k.name)).sort();
return kernels;

#!markdown

# Execute the next cell. After execution, the output immediately below should be:

```
1234
```

And the `POLYGLOT NOTEBOOK: VARIABLES` window should contain a variable with name `csharpVarFromJs`, value `1234` and kernel Name `csharp`

#!javascript

await kernel.root.send({ commandType: 'SubmitCode', command: { code: 'var csharpVarFromJs = 1234; Console.WriteLine(csharpVarFromJs);', targetKernelName: 'csharp' } });

#!markdown

# Execute the next cell. After execution, the output immediately below should be:

```
2345
```
And the `POLYGLOT NOTEBOOK: VARIABLES` window should contain a variable with name `csharpVarFromJsUsingApi`, value `1234` and kernel Name `csharp`

#!javascript

let command = new polyglotNotebooks.KernelCommandEnvelope(polyglotNotebooks.SubmitCodeType, { code: 'var csharpVarFromJsUsingApi = 2345; Console.WriteLine(csharpVarFromJsUsingApi);', targetKernelName: 'csharp' });
await kernel.root.send(command);

#!markdown

# Execute the next cell, the output should be displayed as HTML like so:

<details class="dni-treeview" open=""><summary><span class="dni-code-hint"><code>{ Name = Developer, Salary = 42 }</code></span></summary><div><table><thead><tr></tr></thead><tbody><tr><td>Name</td><td><div class="dni-plaintext"><pre>Developer</pre></div></td></tr><tr><td>Salary</td><td><div class="dni-plaintext"><pre>42</pre></div></td></tr></tbody></table></div></details>

Next, change the renderer using the `...` element, choose the json and the output should look like so:

``` json
{"Name":"Developer","Salary":42}
```

#!csharp

var value = new { Name = "Developer", Salary = 42 };
value.Display("text/html", "application/json");

#!markdown

# Execute the next cell, the output should be displayed like so:

31.1

#!csharp

10m + 21.1m

#!markdown

# Execute the next cell. It should fail with the message:
```
Error: Value 'undefinedVariableName' not found in kernel pwsh
2
```

#!csharp

#!share --from pwsh undefinedVariableName

1+1

#!markdown

# Execute the next cell and verify the following error appears:

```
input.fsx (1,11)-(1,12) parse error Unexpected token '+' or incomplete expression
```

#!fsharp

let x = 1 +

#!markdown

# Complex console output

#!markdown

The output should look like:

<span style="color:#00FF00">this is green</span>

this is white

<span style="color:#FF0000">this is red</span>

#!csharp

Console.Write("\x1b[38;2;0;255;0m");
Console.WriteLine("this is green");
Console.Write("\x1b[0m");
"this is white".Display();
Console.Error.Write("\x1b[38;2;255;0;0m");
Console.Error.WriteLine("this is red");
Console.Error.Write("\x1b[0m");

# vscode kernel and user input prompts
This cell should prompt the user for input. Type something into the input field. Whatever you typed should be displayed in the output.

#!csharp

var input = await Microsoft.DotNet.Interactive.Kernel.GetInputAsync("give me data");
input

#!fsharp

let input = (task  {
                    return! Microsoft.DotNet.Interactive.Kernel.GetInputAsync ("give me data")
                  }).Result
input

#!markdown

This should prompt you for input.

#!value

#!value --from-value @input:wat --name value_from_input

#!markdown

This should output the thing you typed into the prompt.

#!fsharp

#!share --from value value_from_input
value_from_input

#!markdown

Now check the variable explorer. Is the value there in the `value` kernel?

#!markdown

This should prompt you for input. Type something into the input field. Whatever you typed should be displayed in the output.

#!csharp

#!set --name csharpVarFromInput --value @input:"Please enter a value"
csharpVarFromInput

#!markdown

Run the following cell twice. The first time you run it, it should prompt for input and then display the input. The second time you run it, it should display the same input without a user prompt.

#!csharp

#!set --name rememberMe --value @password:{ "prompt": "Please enter a value", "saveAs": "rememberMe" }
rememberMe

#!markdown

Run the following cell twice. The first time it should not display an error. The second time, it should display an error.

#!pwsh

Remove-Secret -Name rememberMe -Vault DotnetInteractive

#!markdown

# Run mermaid markdown:
Execute the markadown in the cell, this should produce a graphic visualization.

# Check this manual scenario:

1. `Ctrl+Shift+P` => "Polyglot Notebook: Create new blank notebook"
2. Select "Create as .dib"
3. Select "F#"
4. You should have a new empty notebook named something like "Untitled-1.dib" with a single cell of type "F# (Polyglot Notebook)".
5. Set the cell contents to `1+1` and execute.
6. Verify output of `2`.
7. Save to disk.
8. Open that file in notepad.
9. The contents should look like this:

   ```
   #!meta
      {"kernelInfo":{"defaultKernelName":"fsharp","items":[{"name":"fsharp","languageName":"F#","aliases":["f#","F#"]},{"name":"vscode","aliases":["frontend"]}]}}

   #!fsharp

   1+1
   ```

#!markdown

# Execute the above scenario again with the following changes:

2. Select "Create as .ipynb"
4. File should be named something like "Untitled-1.ipynb".

(new steps)

9. The contents should look like this:
