Description Dan Callaghan 2014-09-17 00:28:27 UTC
Description of problem:
If a template contains a backslash (for example, as part of a regexp on <input pattern=""/> or anywhere else) the backslash is not escaped when the template is converted to a JavaScript string literal by the JST filter.

Version-Release number of selected component (if applicable):
python-webassets-0.9-1.fc20.noarch

How reproducible:
not easily, but reliably

Steps to Reproduce:
1. Set up a project using webassets JST filter
2. Write a JST template with a backslash, for example: <input pattern="\S+"/>
3. Check the resulting JS file produced by webassets.

Actual results:
window.JST['mytemplate'] = _.template('<input pattern="\S+"/>');

Expected results:
window.JST['mytemplate'] = _.template('<input pattern="\\S+"/>');
