Support heredocs in the formatter for COPY instructions

[rcjsuen]

# syntax=docker/dockerfile:1
FROM alpine
COPY <<-EOT /test.txt
	hello
EOT

const lib = require("dockerfile-utils");
const content = `# syntax=docker/dockerfile:1
FROM alpine
COPY <<-EOT /test.txt
	hello
EOT`;
const edits = lib.format(content);
console.log(edits.length);

We should update the formatter to consider heredocs in COPY instructions.

Thanks for the fix. Would it be possible for this change to trickle down to dockerfile-language-server-nodejs?

when will be published now?very preciate

I have just released a new version of dockerfile-language-server-nodejs (0.10.0) today with this fix. Sorry for the long delay but I have been distracted with other things so I could not get a chance to get this out sooner.
