Fix for Prettier 2

[gakada]

Based on prettier/plugin-php#1359.

[matthargett]

with PR #17 merged, this one can now be closed. thanks for pointing out the plugin-php PR, I think that using their code as a reference for other fixups we need to do will be super helpful!

Dang, sorry @gakada! I totally missed the notification for this PR.

That said, I still think we should merge in this code, since it conditionally handles both prettier 1 and 2.

Could you or @matthargett rebase it and resolve conflicts?

This way, the version check won’t break on Prettier 10 – Prettier 19:

Suggested change

	const prettierVersion = require("prettier").version;
	function lookupIfPrettier2(options, prop) {
	return parseInt(prettierVersion[0]) > 1 ? options[prop] : options;
	const [prettierVersionMajor] = require("prettier").version.split(".", 1);
	function lookupIfPrettier2(options, prop) {
	return parseInt(prettierVersionMajor) > 1 ? options[prop] : options;
