LESS

@import missing "missing" "not missing";

JavaScript

require("postcss-less").parse('@import missing "missing" "not missing";')

Expected Behavior

Error thrown, or missing and "missing" being somewhere on the Import node.

Note: The example code is invalid Less ("malformed import statement").

Actual Behavior

The example Less code parses the same as this:

@import "not missing";

In other words, missing and "missing" are totally ignored.

How can we reproduce the behavior?

require("postcss-less").parse('@import missing "missing" "not missing";')

Background

This causes problems for Prettier when people forget the semicolon after the @import: prettier/prettier#2584

@import "../assets/font/league-gothic/league-gothic.css"

.ManagerPage {
  height: 100%;
}

... is turned into this by Prettier:

@import .ManagerPage {
  height: 100%;
}

... because "../assets/font/league-gothic/league-gothic.css" is entirely missing from the AST. Prettier would need:

• Either an error to be thrown
• or "../assets/font/league-gothic/league-gothic.css" being somewhere on the Import node so that it can be printed back.
