Unterminated template literal, if first line ends slashed

[tmarshall]

• Version: 6.11.3 & 6.10.3
• Platform: Darwin Kernel Version 16.5.0

I have a small script that templatizes a docker RUN command.

const fileContent = `RUN \\
  cd /tmp && \\
  curl -o ./Python-${version}.tgz https://www.python.org/ftp/python/${version}/Python-${version}.tgz && \\
  tar -xzf ./Python-${version}.tgz && \\
  cd ./Python-${version} && \\
  ./configure && \\
  make && \\
  make install && \\
  cd /tmp && \\
  rm -rf ./Python-${version};
`;

This fails giving:

onst fileContent = `RUN \\
const fileContent = `RUN \\
                    ^^^^^^^

SyntaxError: Unterminated template literal

If I change it to the following, it works:

const fileContent = `#comment

RUN \\
  cd /tmp && \\
  curl -o ./Python-${version}.tgz https://www.python.org/ftp/python/${version}/Python-${version}.tgz && \\
  tar -xzf ./Python-${version}.tgz && \\
  cd ./Python-${version} && \\
  ./configure && \\
  make && \\
  make install && \\
  cd /tmp && \\
  rm -rf ./Python-${version};
`;

Using NVM and switching to 8.6.0 does resolve the issue.

I can't reproduce this. I saved this to a file and executed it with node v6.11.3 without any problem:

const version = '2.7';
const fileContent = `RUN \\
  cd /tmp && \\
  curl -o ./Python-${version}.tgz https://www.python.org/ftp/python/${version}/Python-${version}.tgz && \\
  tar -xzf ./Python-${version}.tgz && \\
  cd ./Python-${version} && \\
  ./configure && \\
  make && \\
  make install && \\
  cd /tmp && \\
  rm -rf ./Python-${version};
`;

Ah, so maybe it's only from terminal. I was testing in terminal before executing the full script.

^ also, i was pasting it, if that makes a difference. In v8 it is fine.

It seems unlikely this will get fixed at this point given that the only viable fix was breaking other packages in the ecosystem. I'm going to close this out but if anyone feels strongly about it, feel free to reopen. Also worth noting that v6.x goes into maintenance at the end of April and this is a very low priority issue.
