add newline to template? [message #1831393]

Hello!

My question is quite simple, though I can't find the option to configure the template to add an newline.
Whitespaces seem to be trimmed, so that doesn't work. Any ideas?

I wonder if what you're trying to do is more of a Content Assist -> Templates where you can use ${cursor} to specify where the cursor should go? I don't know that ${cursor} works in the Code Style -> Templates.

You might ask specifically on the JDT forum:

Not quite sure what you mean by content assist. With the cursor I wanted to indicate that indention should also be present.
So that the generated construct can be used directly to write the code on without any further manual formatting.
Aight so the JDT would be right place then to get this solved?

It's not entirely clear to me what you want. In Window -> Preferences -> Java -> Editor -> Content Assist -> Templates there are also templates. And yes, if you have a question specifically about the Java templates those are provided by JDT and the JDT forum is more likely to have an answer.

Sounds like you're looking for the Code Templates preference page, which affects code generation, and not the Content Assist / Templates preference page, which is more for setting up phrases you can expand into proper expressions using content assist (Cmd/Ctrl+Space).

    @Override
    public void play(String x) {
        // TODO Auto-generated method stub

    }

    @Override
    public void play(String x) {
    }

    @Override
    public void play(String x) {
        
    }

The first code block is which comes up when auto-implementing methods with default settings under
Preferences -> Java -> Code Style -> Code Templates -> Code -> Method body

When replacing the comment with a newline in the template it becomes the second example.
As newlines seem to be stripped somehow. What I would like to archieve is the third example.

Are your code formatter preferences set to leave at least one blank line alone?

    @Override
    public void run() {
xxxx
    }

    @Override
    public void run() {
    }

    @Override
    public void run() {
xxxxxxxx
    }

Doesn't seem to help so far. I tried now with these settings, which produce the first block.
Formatter -> Indention -> Empty Lines (yes)
Formatter -> Blank Lines -> At beginning of method body (1)

With the settings it would be worse or equal to the actual settings as now just the
TAB key over the ENTER key needs to be used to archieve the third, desired format.
But actually with the drawback that general formatting is affected in a way it shouldnt.

What seems to be the problem is that newlines/tabs/spaces can be written to the template
but are effectively ignored by the code generator. I wonder if there is any hidden setting
to use them as absolute symbols too.
