For Windows and Linux:

&lt;kbd&gt;Ctrl&lt;/kbd&gt; + &lt;kbd&gt;Shift&lt;/kbd&gt; + &lt;kbd&gt;Space&lt;/kbd&gt;

For MacOS:

&lt;kbd&gt;⇧&lt;/kbd&gt; + &lt;kbd&gt;⌘&lt;/kbd&gt; + &lt;kbd&gt;Space&lt;/kbd&gt;

### Update [v1.6][1] - Aug 2021

There&#39;s also a new feature called **inlay hints** which you can enable in your `settings.json` like this:

```json
&quot;javascript.inlayHints.parameterNames.enabled&quot;: &quot;all&quot;,
```

 2. Search for &quot;Trigger parameter hints&quot;

 2.a Here you can either inspect the defined shortcut
 
2.b Or you can change keybinding by pressing to the left of &quot;Trigger parameter hints&quot; command name.


For Java extension, &lt;kbd&gt;ctrl&lt;/kbd&gt;+&lt;kbd&gt;shift&lt;/kbd&gt;+&lt;kbd&gt;space&lt;/kbd&gt; works **only** after setting `Java &gt; Signature Help: Enabled` in your `settings.json`:

You can use &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Space&lt;/kbd&gt; to show parameter hints before parentheses, and if you want to trigger parameter hints in parentheses to know about arguments you can use &lt;kbd&gt;Ctrl&lt;/kbd&gt;+&lt;kbd&gt;Shift&lt;/kbd&gt;+&lt;kbd&gt;Space&lt;/kbd&gt;

How can a switch expression be written to support multiple cases returning the same result?

With C# prior to version 8, a switch may be written like so:

    var switchValue = 3;
    var resultText = string.Empty;
    switch (switchValue)
    {
        case 1:
        case 2:
        case 3:
            resultText = &quot;one to three&quot;;
            break;
        case 4:
            resultText = &quot;four&quot;;
            break;
        case 5:
            resultText = &quot;five&quot;;
            break;
        default:
            resultText = &quot;unkown&quot;;
            break;
    }

When I am using the C# version 8, with the expression syntax, it&#39;s like so:

    var switchValue = 3;
    var resultText = switchValue switch
    {
        1 =&gt; &quot;one to three&quot;,
        2 =&gt; &quot;one to three&quot;,
        3 =&gt; &quot;one to three&quot;,
        4 =&gt; &quot;four&quot;,
        5 =&gt; &quot;five&quot;,
        _ =&gt; &quot;unknown&quot;,
    };

So my question is: How to turn the cases 1, 2 and 3 to just one switch-case-arm so the value doesn&#39;t need to be repeated?


**Update per suggestion from &quot;*Rufus L*&quot;:**

For my given example, this works.

    var switchValue = 3;
    var resultText = switchValue switch
    {
        var x when (x &gt;= 1 &amp;&amp; x &lt;= 3) =&gt; &quot;one to three&quot;,
        4 =&gt; &quot;four&quot;,
        5 =&gt; &quot;five&quot;,
        _ =&gt; &quot;unknown&quot;,
    };

But it&#39;s not exactly what I want to accomplish. This is still only one case (with a filter condition), not multiple cases yielding to the same right-hand result.

C# 8 switch expression with multiple cases with same result

I&#39;m learning C++ at the moment and try avoid picking up bad habits.
From what I understand, clang-tidy contains many &quot;best practices&quot; and I try to stick to them as best as possible (even though I don&#39;t necessarily understand *why* they are considered good yet), but I&#39;m not sure if I understand what&#39;s recommended here.

I used this class from the tutorial:

    class Creature
    {
    private:
        std::string m_name;
    
    public:
        Creature(const std::string &amp;name)
                :  m_name{name}
        {
        }
    };
This leads to a suggestion from clang-tidy that I should pass by value instead of reference and use `std::move`.
If I do, I get the suggestion to make `name` a reference (to ensure it does not get copied every time) and the warning that `std::move` won&#39;t have any effect because `name` is a `const` so I should remove it.

The only way I don&#39;t get a warning is by removing `const` altogether:

    Creature(std::string name)
            :  m_name{std::move(name)}
    {
    }

Which seems logical, as the only benefit of `const` was to prevent messing with the original string (which doesn&#39;t happen because I passed by value).
But I read on [CPlusPlus.com][1]: 
&gt;Although note that -in the standard library- moving implies that the moved-from object is left in a valid but unspecified state. Which means that, after such an operation, the value of the moved-from object should only be destroyed or assigned a new value; accessing it otherwise yields an unspecified value.

Now imagine this code:

    std::string nameString(&quot;Alex&quot;);
    Creature c(nameString);

Because `nameString` gets passed by value, `std::move` will only invalidate `name` inside the constructor and not touch the original string. But what are the advantages of this? It seems like the content gets copied only once anyhow  - if I pass by reference when I call `m_name{name}`, if I pass by value when I pass it (and then it gets moved). I understand that this is better than passing by value and not using `std::move` (because it gets copied twice).

So two questions:

 1. Did I understand correctly what is happening here?
 2. Is there any upside of using `std::move` over passing by reference and just calling `m_name{name}`?

I want to show parameter hints when I position cursor within the parentheses of the calling method.

I am using the following setup

- [macOS v10.14][1] (Mojave)
- Python 3.7.1
- Visual Studio Code 1.30
- Pylint 2.2.2
- Django 2.1.4

I want to use linting to make my life a bit easier in Visual Studio Code. However, for every import I have states &quot;unresolved import&quot;. Even on default Django imports (i.e. from django.db import models).

I presume it is because it is not seeing the virtual environment Python files.

Everything works just fine, but it&#39;s starting to get annoying.

The interpreter choices I have are all system versions of Python. It does not seem to see my virtual environment Python at all (it is not in the same directory as my workspace, so that part makes sense).

If I set up the *python.PythonPath* in the *settings.json* file, it just ignores it and does not list my virtual environment path as an option. I also tried setting it up in my global Python settings, but it also does not show up.

Is there a quick fix to get it working?

Pylint &quot;unresolved import&quot; error in Visual Studio Code

[Visual Code][1] VS
[Visual Studio Code Insider][2]

I still do not understand what is the difference between the two, could it be that one of them is a trial version for its new functionalities?

What are the differences between Visual Studio Code and Visual Studio Code Insider?

I&#39;ve been using Visual Studio Code since it was in beta and one of the features I like best about it is the integrated terminal for using the Angular CLI in app. I&#39;ve had it working fine since I had the laptop, but I re-installed Windows 10 over the Xmas break and obviously as a result had to re-install Visual Studio Code. 

Since then I&#39;ve had issues with the Terminal, it&#39;s blank until you hit return, at which point you see the path, but not the usual copyright notice you should get from the Windows Command Line.

Before hitting return:
[![VS code Terminal 1][1]][1]

After hitting return:
[![VS Code Terminal 2][2]][2]

And this is what I was expecting directly from the Windows 10 Command Line:
[![Windows Terminal][3]][3]

So far I&#39;ve tried the following:

 - The usual Windows shut down / restart
 - Re-installing VS Code (even changed from regular to insiders)
 - Changing the default Command Line Shell from CMD to Powershell and
   back again
 - Adding a new Command Line Shell

Is there anything else I can try? Has anyone else encountered the same issue?

Visual Studio Code - Terminal Blank Screen

In my project folder I created a *venv* folder:

    python -m venv venv

When I run command `select python interpreter` in Visual Studio Code, my venv folder is not shown. I went one level up like suggested [here][1], but Visual Studio Code doesn&#39;t see my virtual interpreter.

What did I miss?

How can I set up a virtual environment for Python in Visual Studio Code?

I am getting a bit confused here, the latest Anaconda Distribution, 2018.12 at time of writing comes with an option to install Microsoft Visual Studio Code, which is great.

When launching VSC and after `Python: Select Interpreter` and with a fresh install of Anaconda, I can see `~Anaconda3\python.exe` which I assume is the Anaconda Python Environment, however, when I try to run some commands, I am getting:

    PS ~\Documents\Python Scripts\vs&gt; ~/Anaconda3/Scripts/activate
    PS ~\Documents\Python Scripts\vs&gt; conda activate base

&gt; conda : The term &#39;conda&#39; is not recognized as the name of a cmdlet,
&gt; function, script file, or operable program. Check the spelling of the
&gt; name, or if a path was included, verify that the path is correct and
&gt; try again. At line:1 char:1

Now I know that it might be related to the environment variables but I find it highly odd as during the Anaconda installation, there are specific mentions that it is not required to add the Anaconda path to the environment variables. However after the error, the integrated terminal manages to launch Python and I am able to run code.

Next in line is that I am unable to view any variables in the debugger after running a simple script, as shown in the tutorial [here](https://code.visualstudio.com/docs/python/python-tutorial):

    msg = &quot;Hello World&quot;
    print(msg)

I do expect to see similar results as shown in the link such as the dunder variables, I have also updated my `launch.json` with `stopOnEntry = True` following the steps.

I would like to know if it is possible to use Visual Studio Code with Anaconda as a interpreter without registering variables from the original distribution and if I am missing out anything required.

I expected the experience to be more straight forward but also I might be missing something, I am running on *Windows 10.*
