Is it possible to format only a selected block of code. I could only either format the whole file or the whole project with IntelliJ. I use community edition 2017.2 on MacOS.
From the IntelliJ IDEA Help (Reformat File Dialog):
Highlight the block of code.
Open the Reformat File dialog:
Mac: Shift+⌥+⌘+L
Windows/Linux: Ctrl+Alt+Shift+L
Click the "Selected Text" radio button.
Click the "Run" button.
It should look something like this:
Yes; simply highlight the block of code and format it, either through the keyboard or through the menu. How it will be formatted, and what will be formatted, are driven solely by your formatting preferences.
Reformat a code fragment in a file:
In the editor, select a code fragment you want to reformat.
From the main menu, select Code | Reformat Code or press Ctrl+Alt+L.
Note. If you don't select a code fragment, IntelliJ IDEA will reformat the whole file.
When creating a new java class via new -> Java Class while using IntelliJ IDE, a random Dialog started appearing, and I can't find how to disable it.
This is the strange dialog that started showing, a sort of a wizard. Clicking the help button get's me There is no help for this dialog message.
How can I disable this window in the Intellij IDEA?
I too had the same problem, the exact same dialog. In my case, it actually ended up not being a bug, but IJ acting properly (kinda).
TL;DR: The template code for creating a "Class" object got automagically changed after an IJ update so that it would prompt for answers from the coder when creating a new class file. Changing it back in "Settings/File and Code Templates" to the default template code removes the problem, as the default template code does not use any variables that are prompted for upon class object creation (ex.: ${IMPORT_BLOCK}).
Long version ...
Bring up the Settings dialog for IJ, and in the search field type "template", and then select the "File and Code Templates" option. You'll see on the right side of the dialog the "Editor > File and Code Templates" area. If you select "Class" from the list of template types, to the right of that list of template types you'll see the template used when you create a class ...
Now I don't know why, but after a particular IJ update some months back, via their Toolbox app, the default template text/code was different, so that it looked like this ...
... and that latter template code/text caused the second dialog to appear that you see.
To fix the problem, highlight the "Class" template from the list, then click on the "Reset to Default" button that appears below the Files/Includes/Code/Other tabs (looks like a piece of paper with a 180 degree curving arrow on top of it), so that the template text goes back to what I have showing in the first screenshot, and then select the OK button.
Assuming your "default" template for the Class template is not corrupted/bad, you should no longer see the dialog that you asked about.
Go to Settings/File and Code Templates -> class and change it to:
#if (${PACKAGE_NAME} && ${PACKAGE_NAME} != "")package ${PACKAGE_NAME};#end
#parse("File Header.java")
public class ${NAME} {
}
You can also try hitting the reset to default button, as Adrian Romanelli suggested.
Whenever I hit alt-cmd-l to autoformat my code, it formats my imports and arrays from:
import { CommonModule } from '#angular/common';
let arr = [ myStringVar ]; // simple example, just go with it
to
import {CommonModule} from '#angular/common';
let arr = [myStringVar];
How do I tell IntelliJ to put a space after the opening brace and before the close brace when auto-formatting? (Specifically for javascript, typescript)
I've looked around for the answer and could not find one or asked the question badly. So I apologize if this is duplicate.
I'm on Intellij 2016.3.3
Go to preference, select Editor > Code Style > Javascript and choose Spaces, check the checkboxes in Within section "ES6 import/export brances", and if you want spaces in object literal braces, check "Object literal braces" and as well.
Go to settings and search for ES6 import/export braces. It should take you to Editor -> Code Style -> Javascript (or TypeScript). Just hit that checkbox on the spaces tab and it should add the spaces back.
As you are using Angular, I believe you need to edit the settings for the Typescript and NOT for JavaScript. As I am using IntelliJ IDEA 2021, I will give you the fix for the same. You can do so by going through the following path:
Go to File > Settings... > Editor > Code Style > Typescript
Click on the Spaces tab.
In the Within collapsible, tick the checkbox that says "ES6 import/export braces".
Click on Apply button and then click on Ok button.
If you now go to the Typescript file and hit the combo: Ctrl + Alt + L, it should now format the file correctly.
CAVEAT:
You have to be careful to ensure that you are making the changes for the Scheme that is applicable for your project. For example, maybe you have customized your Editor in some way previously and saved your customizations under a new name, such as MyCustomSettings. Once you do this, you will notice that there is an additional Scheme called the Default scheme. But MyCustomSettings will be your Scheme for your project and you have to make sure that you make the changes for the MyCustomSettings Scheme and not for the Default scheme. You can refer to the Schemes via the following path:
File > Settings... > Editor > Code Style > Typescript, there is a dropdown referred as Scheme. Choose the appropriate one for your Project and make sure you make the above edits in that Scheme.
If you open up a class with a publis static void main(String[] args) {} method in Eclipse and hit run, then that class will run. If you move to another class with its own main() method and hit run, then that class will run. Is this possible in IntelliJ IDEA? Or will I have to manually change Run configuration every time I want to run something other than the current run configuration?
You can right click on the class in the Project view and select 'Run YourMainClass.main()'
Alternatively in the text editor with that class open you can right click anywhere in the window and select 'Run YourMainClass.main()'.
Or if you don't want to right click there's a shortcut too (should be displayed in the right click menu - differs by OS)
Doing this will save a configuration in the dropdown as well, so if you go in the edit configurations dialog there you can add vm parameters or any options that need to differ from the default. Configurations created like this have a semi-transparent icon to differentiate them.
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
