Autoclose multiline strings (JEP 368)

Typing """ should automatically insert a new line, indent the cursor position to below the opening quotes, and finally autoclose with a triple quote eg:

String foo = """|

autocloses/completes to (displaying spaces):

String foo = """
.............|
............."""

See https://openjdk.java.net/jeps/368 for more details.

@aeschli any pointers on the best way to achieve that?

@rgrunber not worth doing imo

While you’re at it, can I request that you enclose the center region of text in a C-style indentation?

String foo = """|

will turn into this after pressing Enter key:

String foo = """
....|
"""

Where the center region’s indentation is based on the user-configured indentation size (1, 2, 4, or custom sized indents).

Otherwise, I think this would actually make the enclosures go a bit wild:

String testStringVariableForSpringJUnitMockito_WithMultiLineValues = """|

Would turn into this upon pressing Enter key:

String testStringVariableForSpringJUnitMockito_WithMultiLineValues = """
....................................................................|
....................................................................."""
