LeftCurly FormatterSettings missing for LAMBDA

[MSJones6]

Hi,

I use the actual checkstyle plugin (version 8.12.0.201808161509).
It seems, that the transformer to codeformatter does not support the token "LAMBDA".
No errors in Eclipse message log.
The expression will simply be ignored while creating the formatter.

In the code itsself, the curly bracket is marked as wrong formatted. So, this function works correct.

If I'm correct, the following code is missing in the eclipse-cs/net.sf.eclipsecs.core/src/net/sf/eclipsecs/core/transformer/ctransformerclasses/LeftCurlyTransformer.java (Line 77):
} else if (tok.equals("LAMBDA")) { userFormatterSetting("brace_position_for_lambda_body", option); }

I'm using Eclipse Oxygen.3a (Release 4.7.3a)

There are quite a few tokens missing. I'm not sure which is on purpose and which is missed.

Looks the same for right curly too.

If any are missed on purpose, like not supported in eclipse, then a comment should be made in the source so it is clear and not assumed.

This functionality is part of a contribution made as part of a bachelor thesis. I've never gotten around digging into the code.
I had even toyed with the idea removing this feature altogether, since it's effectively unmaintained.

If someone wants to step up, please do.

Opened #1059 — LeftCurly now maps LAMBDA to brace_position_for_lambda_body.
