pug-walk-extract-text/test.js

Walk and transform a Pug AST, extracting text nodes from e.g. script and style tags

var test = require('tape')
var fs = require('fs')
var lexer = require('pug-lexer')
var parser = require('pug-parser')
var walkExtract = require('./')

function shouldExtract (node) {
	return node.type === 'Tag' && (node.name === 'script' || node.name === 'style')
}

test('extract scripts and styles', function(t) {
	t.plan(1)
	var text = fs.readFileSync('fixture.pug', { encoding: 'utf-8' })
	var results = walkExtract(parser(lexer(text)), text, shouldExtract)
	t.deepEqual(results.map(function (r) { delete r.node; return r }), [
		{ text: "alert('piped')\nalert('piped-no-space')", indent: 8, line: 5 },
		{ text: "print 'hello'", indent: 31, line: 7 },
