This started happening for me in Visual Studio 2019 but does not happen in 2017. I cannot figure out how to stop it.
Something I do all the time is make use of Resharper's reformatting. Suppose I have little block of code like this:
Scan = scan;
Target = target;
IsDone = true;
ShouldAlign = false;
I want to align it up to look all nice and neat. So I select my block of code and I either use the menu or a keyboard shortcut to invoke Resharper's autoformat to line up the equals signs. Voila! Looks great, Here is the reformatted code, exactly as it appears, right after I've reformatted. Note the code is still selected:
But then all I have to do is I click anywhere else in the whitespace of that document, and Boom! Everything gets undone
It is as if VS2019 runs its own "Format Selection" command when I click away But I never did that. (but if I manually do, it has the same effect)
However if instead of just clicking away on the whitespace I, click the menu area of Visual Studio and then click the document whitespace, no problem. No reformat.
Just now I've just finished comparing Visual Studio 2017 and 2019 editing settings side-by-side next to each other. I've compared every single edit/formatting/spacing setting I can possibly find. Both Visual Studio's and Resharper's. They are identical except in those few cases where VS 2019 has some new setting that 2017 did not.
This still happens even when all of VS2019's "automatically format" settings are off
I'm asking the same question of the Resharper folks but I think it has to do with the interaction of the two.
Is anyone else seeing anything like this? It's driving me nuts.
After several hours of this, I have finally discovered that that problem was neither Visual Studio nor Resharper. It was actually a THIRD extension I use (also very common) for C++ files called Visual Assist".
VA has its own "format after paste" option. I am guessing that it must detect the reformat/click away as a "paste" operation and it reformats it according to Visual Studio's settings.
Once I disabled that in single, Visual Assist option VS2019 (as I apparently already had in 2017) everything worked well.
In my Visual studio 2012 editor I erroneously pressed some obscure key combination (Ctrl-Alt-something or so) and now spaces are displayed as little dots and tabs are displayed as arrows.
I'd like to get rid of this, but I haven't found the corresponding option in TOOLS-Options-Text editor.
Go to Edit -> Advanced -> View White Space to rectify this. Alternatively, you may use the key combination Ctrl + R, Ctrl + W.
A quick tip:
An efficient way to find Visual Studio options and commands is to use the "Quick Launch" feature (Ctrl+Q - or just type in the box at the top right of the Visual Studio IDE) - in this case typing "white space" or just "space" in that box shows the command you need and lets you take the action from there too.
How can I set a maximum length for Android Studio's code editor, or may be set a word wrap?
In my Android Studio, no matter how long a statement I type on a single line, it never automatically goes to the next line, but rather a horizontal scroll bar appears.
When I autoformat using the Ctrl+Alt+L (reference), nothing happens.
My SO or Google search found a lot of material on this for Eclipse, but not for Android Studio.
If you need not a soft wrap,
but actually, brake one long line onto several lines you need:
Go to Preferences(mac) or Settings(windows) -> Editor -> Code style -> Java/Kotlin -> Wrapping and braces (tab) -> Check "Ensure that right margin is not exceeded"
Now try to reformat your code:
press
OPTION (ALT) + CMD + L on your Mac
(or CTRL + ALT + L on PC)
Edit 13.02.19
As noted in comments this option seems not available in settings for Kotlin.
However, there is a workaround to manually add it.
Here is what it takes to make it work:
Export the settings scheme.
Open saved xml file.
Find <codeStyleSettings language="kotlin"> tag (or create)
Add the WRAP_LONG_LINES setting manually:
<codeStyleSettings language="kotlin">
...
<option name="WRAP_LONG_LINES" value="true" />
</codeStyleSettings>
Save edits and and import back the scheme.
Here you go!
MacOS:
Click on Android Studio ( left top corner )
Click Preferences
Type Code Style in search
Click on Code Style
There is a filed right to the 'Hard wrap at' - you can enter needed about of symbols you need
In File | Settings, select "Editor", then "Code Style". There is an option "Wrap when typing reaches right margin".
Edit: Just tried it, and it doesn't seem to work. Anyway, maybe the option "Use soft wrap" in the "General" group is more what you want.
#Solace, actually #Fahim Faysal's answer is quite close to what you need, but since you want to solve the problem no matter how long a statement I type on a single line, it never automatically goes to the next line, 2 more steps you need to follow:
[Step 9] type the max length you prefer at `"Hard wrap at" ()
[Step 10] change "Wrap on typing" from Default: No or No to Yes
With version 4.1.2 and with Dart language you need to go to "File/Settings/Editor/Code Style/Dart" and modify the "Line length" to the preferred number.
In Android Studio:
File->Setting->
Editor->code Style->java->Wrapping and braces(tab:right side)->keep when reformatting->Line break(make unchecked)
You can change the max column width from:
File > Settings > Editor > Code Style > Right Margin (columns)
Android Studio 3.5:
Mac -
Android Studio > Preferences > Editor > CodeStyle > HardWrap at: ____
The existing answers already answer the question in straight forward way. As a different approach you could set the style guide to kotlin style guide code style. Then if you do alt + ctrl + l as you did, you'll see auto wrap as you expected.
Just open the settings, search for kotlin and look for kotlin under code style.
On the top right hand side of the settings window you'll see Set from..., click on it.
Then on predifined style > kotlin style guide
If you'd like to follow the kotlin formatting style this could reduce more effort. For more information: https://developer.android.com/kotlin/style-guide
My Environment：
Ubuntu 18.04
AndroidStudio 3.3.2
My operate：
File -> Settings -> Editor -> Code Style
Scheme -> select Project
Hard wrap at '120'
Apply
To move the grey vertical line, that tells Android Studio where to wrap your code, go to
Settings- Editor- Code Style- Java or Kotlin- Wrapping and Braces- Hard wrap at
and enter the number of characters, where the line should be.
For dart
settings => code style => Dart => Line length
In settings/code style/kotlin/wrapping and braces replace the "do not wrap" values with "wrap if long"
You can change the Hard wrap at param
How can I change spacing in Android Studio to use tabs instead of spaces? I tried Preference -> Editor but I don't see the option there. I'm using Android Studio for Mac
Type in 'spac' in the search panel of the settings view.
You will find Editor -> Code Style->Java->Tabs and Indents->Use tab character.
This is a little weird, but others may have the same issue I did.
Yes, follow the above directions, and do the normal changes in the config file. And guess what? it looks like it's still making spaces instead of tabs, even though the settings say TABS, not spaces!
Turn on "show whitespaces" (Editor -> General -> Appearance). And then turn it off. Looks like this is enough to reset the editor so that it is now following the rules you set in the preferences.
In Resharper when I go back to edit some existing code.. eg. wanting to insert a String.Format into this code:
<td>
<%= Html.Encode(item.Address) %>
</td>
I move the cursor to before 'item' and type in 'String.F', getting Resharper's intellisense completion list that includes the 'Format' method.
However if I press TAB then it replaces 'item' with '.Format()'
Is there a way to use completing without replacing the existing text?
Stumbled upon using Enter instead of TAB to choose from the completion list. That does exactly what I want. It surrounds (in this case) 'item.Address' with the String.Format( .. ).
There are two techniques you can use.
The first is to use the Enter key, the second is to pop a space between where you are going to start typing and the next bit of code, which will prevent the next bit of code from being overwritten.
There is an actual setting now to disable this (annoying) behavior.
Go to the Options dialog (Menu -> Resharper -> Options).
In this Options dialog go to Environment -> IntelliSense -> Completion Characters.
Here you can set the Tab behavior to Insert instead of Replace.

This is an addition to the answer in 2010, for everyone that reaches this post via populair search engines ;)
You could also use the String.Format surround template but you may have to map a hotkey to it for easier access.
The keyboard command you want to use is called: Resharper_ForceCompleteItem. So if you go into Visual Studio's Tools > Options > Environment > Keyboard you could assign a keyboard shortcut there. Not sure if it would be possible to use Tab, though.
