Press `Ctrl+Shift+a` and search for `console font`:

Select `Console Font` and the right settings menu will be opened.

## Intellij Version &lt; 2018

Open `Settings -&gt; Editor -&gt; Colors &amp; Fonts -&gt; Console Font`

You can change font size and colors there but you have to save the Scheme into a custom scheme before you can change the values.

I am using the ultimate edition. If you don&#39;t see that settings it&#39;s probably because of the community edition you are using.

I use [eslint-config-airbnb](https://github.com/airbnb/javascript/tree/master/packages/eslint-config-airbnb) to check the above code and it show me an error msg like ` Component should be written as a pure function ` .

So how to change the above component to pure function?

Thanks for your help.

I have a custom type which internally has a slice of data.

Is it possible, by implementing some functions or an interface that the range operator needs, to iterate (using range) over my custom type?

In Go is it possible to iterate over a custom type?

**What is the *best* &#39;NonNull&#39; annotation?**

**&quot;Best&quot;** in the sense of

* Standard way e.g. future proofness (e.g. support by standard jdk etc.)
* Support of IDE&#39;s (shows up in java doc to indicate the usage for developers)
* Support by static analysis tools like findbugs
* Support for runtime analysis

Here&#39;s how the world currently look like - any further insight is appreciated:

 - **`javax.validation.constraints.NotNull`** ([Docs][2])   
   \+ javax package thus seems futureproof   
   \- Part of JEE **not** JSE. In JSE need to [import additional libs][3].   
   \- Not supported by static analysis tools (runtime validation only)

 - &lt;s&gt;**`edu.umd.cs.findbugs.annotations.NonNull`**&lt;/s&gt; ([docs][4])  
    \- external library and not an `javax` package  
    \- [deprecated][4] since findbugs version 3.X  
    \+ used for static analysis (by findbugs and therefore Sonar)    

 - &lt;s&gt;**`javax.annotation.Nonnull`**&lt;/s&gt; ([docs][5])  
    \+ used for static analysis (in findbugs)  
    \- [JSR-305][6] is dormant/dead/unknown as on the [fb mailing list][7] indicated. The author Bill Pugh, even if directly asked, hasn&#39;t commented the state in years...

 - &lt;s&gt;**`org.eclipse.jdt.annotation_2.0.0`**&lt;/s&gt; ([docs][8], interesting [presentation][9])  
    \+ used for static analysis (in eclipse not in findbugs though)  
    \- proprietary to eclipse (didn&#39;t try to use them standalone)
    
 - &lt;s&gt;**`org.jetbrains.annotations.NotNull`**&lt;/s&gt; ([docs][10])    
    \+ used for static analysis (in intelliJ not in findbugs though)  
    \- proprietary to IntelliJ (but also publicly available as a jar)

 - **`lombok.NonNull`**([docs][11])  
    \+ used to control code generation  
    \- proprietary annotation

 - **`android.support.annotation.NonNull`** ([docs][12])   
    \+ static analysis in android studio  
    \- android specific proprietary annotation

 - **`org.checkerframework.checker.nullness.qual.NonNull`** ([docs][13])  
   \+ [JSR308][14] implementation which is part of Java8 (which did introduce the ability to write annotations in different parts of your code, but did not introduce new annotations)  
   \+ used for static code (not findbugs though) **and** runtime analysis  
   \- external lib however seems to be [endorsed][15] by the java folks 

Currently I would tend to the [Checker Framework][16] but I am looking forward for other views...

Which @NonNull Java annotation to use

I love intellij&#39;s file tab but I can&#39;t seem to find a way to shortcut closing a tab similar to the behavior of `ctrl + w` in chrome. I can&#39;t find the option in the keymap editor. Am I missing something or is this not implemented?

I found this &lt;a href=&quot;https://www.jetbrains.com/idea/help/closing-files-in-the-editor.html&quot;&gt;page&lt;/a&gt; but it doesn&#39;t include the action name. I would use `ctrl + f4` but my window manager has that reserved and I would rather change it. 

Shortcut to Close Intellij File Tab

Since I&#39;ve updated my version of intelliJ (14.x to 15.x) it has started automatically collapsing single line methods in the `Java` editor:

Previous version:

    public void setContext(SecurityContext context) {
        this.context = context;
    }

Latest version:

    public void setContext(SecurityContext context) { this.context = context; }

Is there a way to prevent this?  I find the original version much easier on the eyes!

Thanks.

IntelliJ collapsing single line methods

IntelliJ keeps formatting this:

    public void addElement(Element elem) {
        this.elements.add(elem);
    }

into this:

    public void addElement(Element elem) { this.elements.add(elem); }

I prefer the multi-line formatting. How can I tell this to IntelliJ? I have unchecked the following boxes in Settings -&gt; Editor -&gt; Java -&gt; Wrapping and Braces

- Control statements in one line
- Simple blocks in one line
- Simple methods in one line

Didn&#39;t help.

IntelliJ IDEA one-line function formatting

I use IntelliJ IDEA 15 and have a problem with the auto-saving. For example I make a new configuration, e.g. Show the line number. When I close IntelliJ and reopen my IDE, it doesn&#39;t save my configuration and shows me this message:

&gt;    Unable to save settings : Failed to save settings . Please restart IntelliJ IDEA

If you look at the VS Code terminal - its too tiny.

Here&#39;re the user settings that I have modified to create this result.  I have searched how to change terminal fonts at VS Code, but I have followed all instructions pertaining to 
`terminal.integrated.fontSize` and this doesn&#39;t help at all - it only lengthens the line.

Please advise - thanks in advance.

My terminal in VS Code has a tiny font after installing zsh and changing font style

Querying for `fontsize` in `User Settings` window yields only settings for: 

 - editor panes,
 - suggest widget,
 - markdown preview,
 - integrated terminal

as you can see below:

[![enter image description here][1]][1]

Doing the same for `sidebar` gives even poorer results:

Having fonts of different sizes in editor panes and sidebar looks... let&#39;s settle with: *not too nice*. Have I just found the greatest omission of this awesome tool?

How to change font size in VS Code sidebar?

I couldn&#39;t figure out how to increase or how to use the default font size for the preview text when hovering over an autocomplete suggestion from the browser.

I&#39;m using https://tailwindcss.com/ for all styles.

E.g.:

This is my normal input element with the default font size after entering some text:

[![enter image description here][1]][1]

And this is the font size of the preview when I hover one of the suggested autocomplete items:

[![enter image description here][2]][2]

As you can see, the font size is much smaller than in the first image.

[![enter image description here][3]][3]

I&#39;m already using some CSS-snippet to disable all browser-specific stylings:

```lang-css
input:-webkit-autofill,
input:-webkit-autofill:hover,
input:-webkit-autofill:focus,
textarea:-webkit-autofill,
textarea:-webkit-autofill:hover,
textarea:-webkit-autofill:focus,
select:-webkit-autofill,
select:-webkit-autofill:hover,
select:-webkit-autofill:focus {
  border: inherit;
  -webkit-text-fill-color: inherit;
  -webkit-box-shadow: inherit;
  transition: background-color 5000s ease-in-out 0s;
  font-size: inherit;
}
```

The last property `font-size` does nothing.

I&#39;m using the following css for the input font-size:

```lang-css
    font-size: 1.125rem !important;
```

I also tried to assign the font-size as inline-style to fix it, but it doesn&#39;t work as well:

[![enter image description here][4]][4]

Live example: https://codesandbox.io/s/o766kp4z05
Use the example and try to enter your email into the email field and look at the font size. It has the same problem with the font size.

Is it possible to fix the font size?
