This plugin treats Jinja template expressions and statements as valid Javascript expressions, so that ESLint can check javascript code, ignoring any Jinja expression found.
As a note, it is possible that this best effort conversion yeilds false negatives or positives because it is impossible to know the right way to insert placeholders.
Plugin will convert (internally) this code:
(function() {
'use strict';
{# plain jinja variables are converted into strings
(preferred quotes are getting from .eslintrc file) #}
var a = 'this is' + {{ some_variable }};
{# if it is already in string, it is wrapped with spaces #}
var b = 'this is {{ other_variable }}';
var c = 'and this is {{ another_one['field']}}';
{# if-else statements are converted into ( ..., ... ) expression #}
var d = {% if something %} 'this is something' {% else %} null {% endif %};
{# any other statements become comments #}
{% for i in [1, 2, 3] %}
console.log(a, b, c, d);
{% endfor %}
})();into this:
(function() {
'use strict';
/* plain jinja variables are converted into strings
(preferred quotes are getting from .eslintrc file) */
var a = 'this is' + ' some_variable ';
/* if it is already in string, it is wrapped with spaces */
var b = 'this is other_variable ';
var c = 'and this is another_one[ field ] ';
/* if-else statements are converted into ( ..., ... ) expression */
var d = (/*if something */ 'this is something' ,/*else */ null /*endif */);
/* any other statements become comments */
/* for i in [1, 2, 3] */
console.log(a, b, c, d);
/* endfor */
})();
