How do you auto-format code in Eclipse?

how did you post a question with meeting the "quality standards". for me, it is a very simple question. i just wanted to know how you did that – Phanerozoic 12/9, 2016 at 11:5

It's a very simple question, but if it hasn't been answered yet then it is a question we need. So that when someone else has the same simple question they can come and find it here. – Carlyn 11/8, 2017 at 12:22

Will auto format applies to js files? – Bisectrix 11/1, 2019 at 9:33

On Windows and Linux : Ctrl + Shift + F

On Mac : ⇧⌘F

(Alternatively you can press Format in Main Menu > Source)

@SSHThis it's the Shift key – Demonolater 26/11, 2014 at 23:31

I have some errors in my file. Can this be a reason for the above to not work?? – Perplex 6/12, 2016 at 7:46

These shortcuts won't work if you have errors in your file. On windows at least. – Recuperator 5/3, 2018 at 20:26

On Linux Ubuntu and Mint distros, ctrl + shift + f works as well. Thanks – Veterinarian 21/3, 2018 at 8:27

PERFECTO, <- I have written this with a shift, btw. :D – Survance 19/9, 2018 at 18:16

Does anyone know where the settings for the autoformatter are stored (like a local XML file somewhere). I'd like to distribute a team-wide settings file for my group so there aren't any inconsistencies with formatting between different OSes. – Hillie 3/12, 2018 at 19:34

The path in eclips (Version: 2021-06 (4.20.0)) is Main menu => Source=>Format – Polarization 14/9, 2021 at 6:15

Another option is to go to Window->Preferences->Java->Editor->SaveActions and check the Format source code option. Then your source code will be formatted truly automatically each time you save it.

A lot of options there it's really worth looking, also good to include the auto @Override statement on save – Timmerman 13/3, 2014 at 10:26

@HasanAboShally, now you just press two :D – Chongchoo 29/3, 2018 at 10:21

This option can now be found in Eclipse->Preferences->Java->Editor->SaveActions – Trehalose 8/10, 2019 at 16:8

CTRL + SHIFT + F will auto format your code (whether it is highlighted or non highlighted).

This can also be done at the Project Level: In the Package Explorer, right-click on the project > Properties > Java Editor > Save Actions

This might be preferable when working as a team so that everyone's code is saved with the same format settings.

Notice: It did not format the document unless I corrected all mistakes. Check your file before pressing CTRL + SHIFT + F.

Press: Ctrl + A or highlight the part of the code you wish to indent and then press Ctrl + I.

That's an I for "Indent". – Boyhood 11/4, 2014 at 17:53

Windows -> Preferences -> Java -> Editor -> save actions -> Format source code -> Format Edited lines (or) format all lines.

Some time when you work as a team, lead don't want you to format all lines of the code in a source file (Huge track changes will be there on commit). So, select 'Format Edited lines'. This will edit and format only the lines you modified.

Also note that you can also "protect" a block from being formatted with @formatter:off and @formatter:on, avoiding a reformat on a comment for example, like in:

// Master dataframe
Dataset<Row> countyStateDf = df
    .withColumn(
        "countyState",
        split(df.col("label"), ", "));

// I could split the column in one operation if I wanted:
// @formatter:off
//    Dataset<Row> countyState0Df = df
//        .withColumn(
//            "state",
//            split(df.col("label"), ", ").getItem(1))
//        .withColumn(
//            "county",
//            split(df.col("label"), ", ").getItem(0));
// @formatter:on

countyStateDf.sample(.01).show(5, false);

Update your IDE with the latest PDT version for better code formatting. On the main menu click Help -> Install New Software and then add the following URL in the Work with field:

http://download.eclipse.org/tools/pdt/updates/4.0.1

When asked for the name, give it PDT4.0.1 and then move along with the update or install.

It will see if the appropriate PDT is already installed or if it is a lower version, which then would be updated.

After restarting or applying the changes go to Windows -> Preferences on the side bar and expand PHP -> Code Style. Here you will see an item named Formatter. Select it and choose the active profile for the code formating. Thats it.

The next time you format it, it will choose a format according to the chosen active profile.

Hope it helps.
