I pressed something in Intellij and my caret shape changed to this. How to revert to the normal thickness? Using Intellij 2016.1.
Compare to this, normal thickness should be that of a bold vertical line:
Update: On Android Studio 2.1 beta, same machine, same font settings, cursor is visibly thinner.
You can .. but it's not pixel perfect. I mean -- for me the value does not seem to control thickness in pixels but rather some index (which gets applied to some predefined values) -- at least this is my impression on what I see my computer.
In any case:
Help | Find Action...
Search for registry action
Once in Registry window -- look for editor.caret.width entry
Set the new value (for me the default was 2) -- make sure that field went bold (move to another entry) to ensure that new value was accepted.
Restart IDE (this option requires it)
UPDATE (2017/04/06):
You may also try ThinCaret plugin:
Makes your editor caret 1 pixel thin (for retina users)
You can change it under Settings -> Editor -> General -> Appearance -> Use Block caret
Other caret settings are under Settings -> Editor -> Colors & Fonts -> General. Then if you scroll down to the editor section on the right, there is a caret item in the list with font/color settings.
Please check the Picture for solution.
If you got here because of the thick cursor (block cursor) that behaves differently than the normal thin one. Just press the insert (Ins) button once and you are good to go.
Go to the Keymaps section of the Preferences and add your own Keyboard shortcut if you are using a Mac. Windows users can just enable/disable Insert mode on their keyboard.
I am wondering how to align (the keyboard shortcut) a line or a block of code with the previous line, so that they have the same indention or starting from the same column in IntelliJ and PyCharm.
cheers
I think that "Emacs Tab" could help you. You can use setting search to find it or you can go Preferences -> Appearance & Behaviour -> Keymap. It is editor action and in some Keymap settings it doesn't have assigned key shortcut. I personally prefer remap Tab key to this action.
I'm really impressed with the autocomplete feature of the IntelliJ IDE so far.
What I'd like to do, is cycle through the autocomplete suggestions I get when hitting Ctrl + Space without using the arrow keys (↑, ↓).
The reason for this is that I prefer to keep my fingers on the home row (I'm using IntelliJ's Vim emulator additionally).
For example, how would I select sortThis instead of sorted without using the arrow keys or the mouse?
Peter Gromov's answer brought me to a satisfying solution:
In IntelliJ's settings, for Keymap → Editor Actions → Down I set a custom shortcut: Ctrl + J.
This way I can cycle forward through the suggestions.
Setting a shortcut for Down with Selection or Scroll Line Down in the IdeaVim-specific shortcuts did not affect the selection of autocomplete suggestions though.
The answer here: https://stackoverflow.com/a/9713306/2370679 led me to discover that Ctrl+n & Ctrl+p allow navigation of the auto-complete options without having to modify any settings
For macOS the IDE will give a hint that "^↑ and ^↓ will move caret up and down in the editor". These clearly do not work.
There are a few extra steps that are needed after following #matthias-braun's solution.
Here is the full list of step that I use:
Go to Preferences -> Keymap
Expand Editor Actions (not Plug-ins -> IdeaVim)
Select Down
Click the pencil icon or right-click
Select Add Keyboard Shortcut
Press the shortcut (I use ^N)*
Repeat for 3-6 for Up (I use ^P)
Click Ok**
Go to Preferences -> Other Settings -> Vim Emulation
In the drop-down under the Handler column for the row containing Down, select Vim***
Do the same thing for Up
* If you are warned about the key binding already existing then remove it. You can always reset back to the defaults by clicking the little cog icon up the very top to the right of the drop-down menu.
** The Vim Emulation doesn't seem to be populated correctly until you reopen the Preferences.
*** I'm not sure why the Handler should be Vim. This seems backwards to me but it works.
If you're able to scroll up/down in editor with some IdeaVIM-specific shortcuts, they should also work in the completion list.
In this particular case, I'd just type another "t" so that "sortThis" becomes selected (and the only) variant.
I have done the same thing with mapping the arrows but in a more logical way:
I mapped them that when I press 'Alt' 'J' is left, 'L' is right, 'I' is up, and 'k' is down. that way I can have easy access to the arrows while my fingers are on the home row and I don't need to move them nearly as much...
I'm posting it just so people who search it on google can have that idea.
See the screenshot below to see what I mean. Basically, Intellij only highlights the box I draw with the cursor, but leaves the rest of the editor untouched. I have no idea why it happens, and the only way to resolve it for now is to close and reopen the editor. I have observed the same behavior on a Linux box and a MacBook, both when editing Java and PHP files, so I am not sure it's a bug.
The desired behaviour is standard row selection, i.e. highlight all rows which I drag the cursor over.
I think you have enabled 'column selection'.
Option can be toggled via these methods:
Menu Bar -> Edit -> Column selection mode
Document Body -> Right Click -> Column selection mode
Keyboard Shortcut -> ALT + SHIFT + INSERT
The column select mode is enabled, use Alt+Shift+Insert to enable or disable this mode.
Shift-command-8 to toggle it back and forth on OSX.
I remember seeing in either IntelliJ or Eclipse the setting to reformat (cleanup) files whenever they are saved. How do I find it (didn't find it in the settings)
This solution worked better for me:
Make a macro (I used Organize Imports, Format Code, Save All)
Assign it a keystroke (I overrode Ctrl+S)
Note: You will have to check the box "Do not show this message again" the first time for the organized imports, but it works as expected after that.
Step-by-step for IntelliJ 10.0:
Code -> "Optimize Imports...", if a dialogue box appears, check the box that says "Do not show this message again.", then click "Run".
Tools -> "Start Macro Recording"
Code -> "Optimize Imports..."
Code -> "Reformat Code..."
File -> "Save all"
Tools -> "Stop Macro Recording"
Name the macro (something like "formatted save")
In File -> Settings -> Keymap, select your macro located at "Main Menu -> Tools -> "formatted save"
Click "Add Keyboard Shortcut", then perform the keystroke you want. If you choose Ctrl+S like me, it will ask you what to do with the previous Ctrl+S shortcut. Remove it. You can always reassign it later if you want.
Enjoy!
For IntelliJ 11, replace
step 2. with: Edit -> Macros -> "Start Macro Recording"
step 6. with: Edit -> Macros -> "Stop Macro Recording"
Everything else remains the same.
IntelliJ 12
8. The Preferences contain the Keymap settings. Use the input field to filter the content, as shown in the screenshot.
I suggest the save actions plugin. It also supports optimize imports and rearrange code.
Works well in combination with the eclipse formatter plugin.
Search and activate the plugin:
Configure it:
Edit: it seems like it the recent version of Intellij the save action plugin is triggered by the automatic Intellij save. This can be quite annoying when it hits while still editing.
This github issue of the plugin gives a hint to some possible solutions:
https://github.com/dubreuia/intellij-plugin-save-actions/issues/63
I actually tried to assign reformat to Ctrl+S and it worked fine - saving is done automatically now.
Below is Neil's answer updated.
IntelliJ 13 Steps:
Code -> Reformat Code
Edit -> Macros -> Start Macro Recording
Code -> Reformat Code
File -> Save all
Edit -> Macros -> Stop Macro Recording
Name the macro (something like "formatted save")
File -> Settings -> Keymap
Right click on the macro. Add Keyboard Shortcut. Set the keyboard shortcut to Control + S.
IntelliJ will inform you of a hotkey conflict. Select "remove" to remove other assignments.
I set it to automatically clean up on check-in, which is usually good enough for me. If something is too ugly, I'll just hit the shortcut (Ctrl-Alt-L, Return). And I see they have an option for auto-formatting pasted code, although I've never used that.
If you have InteliJ Idea Community 2018.2 and above the steps are as fallows:
In the top menu you click: Edit > Macros > Start Macro Recordings
(you'll see a window lower right corner of your screen confirming
that macros are being recorded)
In the top menu you click: Code >
Reformat Code (you'll see the option being selected in the lower
right corner)
In the top menu you click: Code > Optimize Imports
(you'll see the option being selected in the lower right corner)
In the top menu you click: File > Save All
In the top menu you click: Edit > Macros > Stop Macro Recording
You name the macro: "Format Code, Organize Imports, Save"
In the top menu you clock: File > Settings. In the settings windows you click Keymap
In the search box on the right you search "save". You'll find Save All (Ctrl+S). Right click on it and select "Remove Ctrl+S"
Remove your search text from the box, press on the Collapse All button (Second button from the top left)
Go to macros, press on the arrow to expand your macros, find your saved macro and right click on it. Select Add Keyboard Shortcut, and press Ctrl+S and okay.
Restart your IDE and try it.
I know what you're going to say, the guys before me wrote the same thing. But I got confused using the steps above this post, and I wanted to write a dumb down version for people who have the latest version of the IDE.
Ctrl + Alt + L is format file (includes the two below)
Ctrl + Alt + O is optimize imports
Ctrl + Alt + I will fix indentation on a particular line
I usually run Ctrl + Alt + L a few times before committing my work. I'd rather it do the cleanup/reformatting at my command instead of automatically.
Rejoice! In IDEA 2021.2 there is finally "File->Settings->Tools->Actions on Save" where you can select "Reformat code", "Optimize imports", "Rearrange code", "Run code cleanup", "Run eslint --fix" etc.
If you're developing in Flutter, there's a new experimental option as of 5/1/2018 that allows you to format code on save.
I wound up rebinding the Reformat code... action to Ctrl-S, replacing the default binding for Save All.
It may sound crazy at first, but IntelliJ seems to save on virtually every action: running tests, building the project, even when closing an editor tab. I have a habit of hitting Ctrl-S pretty often, so this actually works quite well for me. It's certainly easier to type than the default bind for reformatting.
IntellIJ 14 && 15: When you are checking in code in Commit changes dialog, tick the Reformat code checkbox, then IntelliJ will reformatting all the code that you are checking in.

For PyCharm/IntelliJ IDEA:
Install black.
$ pip install black
Locate your black installation folder.
On macOS / Linux / BSD:
$ which black
/usr/local/bin/black # possible location
On Windows:
$ where black
%LocalAppData%\Programs\Python\Python36-32\Scripts\black.exe # possible location
Note that if you are using a virtual environment detected by PyCharm, this is an unneeded step. In this case the path to black is $PyInterpreterDirectory$/black.
Open External tools in PyCharm/IntelliJ IDEA
On macOS: PyCharm -> Preferences -> Tools -> External Tools
On Windows / Linux / BSD: File -> Settings -> Tools -> External Tools
Click the + icon to add a new external tool with the following values:
Name: Black
Description: Black is the uncompromising Python code formatter.
Program: <install_location_from_step_2>
Arguments: "$FilePath$"
Format the currently opened file by selecting Tools -> External Tools -> black.
Alternatively, you can set a keyboard shortcut by navigating to Preferences or Settings -> Keymap -> External Tools -> External Tools - Black.
Optionally, run Black on every file save:
Make sure you have the File Watchers plugin installed.
Go to Preferences or Settings -> Tools -> File Watchers and click + to add a new watcher:
Name: Black
File type: Python
Scope: Project Files
Program: <install_location_from_step_2>
Arguments: $FilePath$
Output paths to refresh: $FilePath$
Working directory: $ProjectFileDir$
Uncheck “Auto-save edited files to trigger the watcher” in Advanced Options
To format Python files with Black, I followed this guide, which also uses File Watcher:
https://black.readthedocs.io/en/stable/editor_integration.html
Since version 2020.1, you can activate Run on save for files directly in the Preferences of the Prettier plugin:
I thought there was something like that in IntelliJ, but I can't find it. The only clean-up that happens at save is that white space at the ends of lines is removed. I thought I had to specify that behavior at one point, but I don't see anything related at this point.
If it's about Prettier, just use a File Watcher :
references => Tools => File Watchers => click + to add a new watcher => Prettier
