If you have a large amount of code to share which demonstrates the problem you're experiencing, please provide a link to your
repository rather than pasting code. Otherwise, please paste relevant short snippets below.

LESS

@var: '
foo
bar
';

JavaScript

const postcss = require('postcss');
const syntax = require('postcss-less');

const lessText = `@var: '
foo
bar
';`;

postcss([])
  .process(lessText, { syntax: syntax })
  .then(function (result) {
    console.log(result.root.first)
});

Expected Behavior

An AST similar to this:

{
  ...
  source: {
    start: { line: 1, column: 1 },
    end: { line: 4, column: 2 }
  }
}

Actual Behavior

An AST looking like this (note the end line):

{
  ...
  source: {
    start: { line: 1, column: 1 },
    end: { line: 1, column: 18 }
  }
}

How can we reproduce the behavior?

Run the JS example above.

The original issue used a tilde-escaped string but I've managed to reproduce it with any multiline variable. I'm not really sure how to solve it, but I'll continue to think about it.

Good news. This is fixed by the work being done in #113.
