What is this empty non-numbered row in IntelliJ? How can it disable me? Class should be on line 3.
Disable "Preferences | Editor | Inlay Hints | Code Vision"
We are working on the fix already: https://youtrack.jetbrains.com/issue/IDEA-290051/Code-Vision:-inlay-consumes-vertical-space-in-the-editor-even-wh
I'm having issues with IntelliJ automatic Reformat Code on one specific line of code:
catch (MyException1 | MyException2 | MyException3 | MyException4 | MyException5 | MyException6 | MyException7 | MyException8 e) {
I have set in Editor -> Code Style Hard wrap at 140
In Editor -> Code Style -> Java -> Wrapping and Braces everything is either Chop down if Long or Wrap if long
Now, the issue is that running Code -> Reformat Code doesn't break this line into 2 automatically (it should as it exceeds 140 characters). And what's worse, if I break it manually, then Reformat Code will bring it back to one line. As I have the Line Length inspection on, IntelliJ complains about this line.
This is the only line in the whole project where IntelliJ has this problem, all other expressions containing + or || etc. are correctly wrapped.
Wrapping or chopping down multi-catch types is not supported on IntelliJ IDEA 2021.3 and below. IntelliJ IDEA 2022.1 will support this. See https://youtrack.jetbrains.com/issue/IDEA-178941
Question please on IntelliJ.
Currently, IntelliJ "folds" code that are one liners. Something like:
public String getFoo() { return foo; }
A insist, it is just a visual. On the file itself, it is not folded, just on the visual of the IDE.
public String getFoo() {
return foo;
}
On Mac, on each start of IntelliJ, I am currently selecting all files and pressing "shift" + "command + "plus sign +" to expand all files.
Is there a way to have by default files with expand all?
Thank you
Disable these settings:
Settings (Preferences on macOS) | Editor | General | Code Folding | Simple property accessors
Settings (Preferences on macOS) | Editor | General | Code Folding | One-line methods
Using IntelliJ 2018.1 I noticed that on certain files multi-line simple comments are always folded:
// My multi
// line
// comment
becomes
//...
How do I turn it off? I need to always see my comments.
Settings | Editor | General | Code Folding | [ ] End of line comments sequence
I was wondering how I can change the line length in IntelliJ.
Since I use a pretty high resolution, I get that line that shows 120 characters straight through the middle of the screen. Can I change it from 120 to, say, 250?
IntelliJ IDEA 2018
File > Settings... > Editor > Code Style > Hard wrap at
IntelliJ IDEA 2016 & 2017
File > Settings... > Editor > Code Style > Right margin (columns):
You can alter the "Right margin" attribute in the preferences, which can be found via
File | Settings | Project Settings | Code Style - General
Right Margin (columns) In this text box, specify the number of columns
to be used to display pages in the editor.

It seems like Jetbrains made some renaming and moved settings around so the accepted answer is no longer 100% valid anymore.
Intellij 2018.3:
hard wrap - idea will automatically wrap the line as you type, this is not what the OP was asking for
visual guide - just a vertical line indicating a characters limit, default is 120
If you just want to change the visual guide from the default 120 to lets say 80 in my example:
Also you can change the color or the visual guide by clicking on the Foreground:
Lastly, you can also set the visual guide for all file types (unless specified) here:
It may be useful to notice that very good answers given above may not be enough. It is because of one more tick is required here:
Be aware that need to change both location:
File > Settings... > Editor > Code Style > "Hard Wrap at"
and
File > Settings... > Editor > Code Style > (your language) > Wrapping and Braces > Hard wrap at
I didn't understand why my this didn't work but I found out that this setting is now also under the programming language itself at:
'Editor' | 'Code Style' | < your language > | 'Wrapping and Braces' | 'Right margin (columns)'
Open .editorconfig in the root of your project (or create one if you don't have any) and add:
max_line_length = 80
The IDE should pick it up immediately (works in PhpStorm, developed by the same company). As a bonus, it can be committed to GIT and will stay consistent across different editors you may be using in the future. More info on .editorconfig.
