Interpolation break on attributes

[SebastianGrzymala]

This code doesn't work:

[ 'host' => 'http://www.abc.com/', 'filename' =>'def.jpg' ]

a(href=host + filename) Link

https://pug-demo.herokuapp.com/ script returns:

<a href="0">Link</a>

Should be:

a(href="http://www.abc.com/def.jpg") Link

Pug node returns as above

I fixed it using this code: a(href=''+host + filename) Link

You should be in the default expressionLanguage mode (auto), and indeed, in this mode, your only way to be sure to have a string concatenation is to start with a empty string because the auto mode try to guess if your expressions are in PHP or JS.

But you can also choose the PHP mode and write all your expressions in PHP:

$pug = new Pug(array('expressionLanguage' => 'php'));
echo $pug->render('a(href=$host . $filename) Link', array(
    'host' => 'http://www.abc.com/',
    'filename' =>'def.jpg'
));

Or choose the JS mode and so you will be able to use JS expression with a better support:

$pug = new Pug(array('expressionLanguage' => 'js'));
echo $pug->render('a(href=host + filename) Link', array(
    'host' => 'http://www.abc.com/',
    'filename' =>'def.jpg'
));

Feel free to re-open if you have more questions about it.
