Thanks for the neat tool!

I've run into an issue with jinja2 when close a html tag inside of a jinja2 if statement. Something simple like this -

<!DOCTYPE HTML>
<div>
    {% if a == 1 %}
        </div>
        <h1>a</h1>
        <div>
    {% endif %}
</div>

will produce this error:

test.html 3:9 Parse error: expected one of '[:a-zA-Z]', 'animate', 'animateMotion', 'animateTransform', 'area', 'base', 'br', 'circle', 'col', 'ellipse', 'embed', 'feBlend', 'feColorMatrix', 'feComposite', 'feConvolveMatrix', 'feDisplacementMap', 'feDistantLight', 'feDropShadow', 'feFlood', 'feFuncA', 'feFuncB', 'feFuncG', 'feFuncR', 'feGaussianBlur', 'feImage', 'feMergeNode', 'feMorphology', 'feOffset', 'fePointLight', 'feSpotLight', 'feTile', 'feTurbulence', 'hr', 'image', 'img', 'input', 'line', 'link', 'meta', 'mpath', 'param', 'path', 'polygon', 'polyline', 'rect', 'script', 'set', 'source', 'stop', 'style', 'track', 'use', 'wbr', '{#', '{%', '{{' at 3:9   parse_error

I'm on a Mac using python 3.9 w/ the latest version of curlylint.

curlylint test.html

The general syntax validation seems to work well up until this step. Possible could the template tags be stripped out for this particular test? Or allow close / open tags out of sequence inside an if statement?

Or ideas for a better way to write jinja are also welcome :)
Thanks!

I see there is a comment in the code for a similar situation -

Having the same issue with the opening tags. For example:

{% if is_div %}
<div>
{% endif %}

Test

</div>

6:1	Parse error: expected one of '[:a-zA-Z]', 'animate', 'animateMotion', 'animateTransform', 'area', 'base', 'br', 'circle', 'col', 'ellipse', 'embed', 'feBlend', 'feColorMatrix', 'feComposite', 'feConvolveMatrix', 'feDisplacementMap', 'feDistantLight', 'feDropShadow', 'feFlood', 'feFuncA', 'feFuncB', 'feFuncG', 'feFuncR', 'feGaussianBlur', 'feImage', 'feMergeNode', 'feMorphology', 'feOffset', 'fePointLight', 'feSpotLight', 'feTile', 'feTurbulence', 'hr', 'image', 'img', 'input', 'line', 'link', 'meta', 'mpath', 'param', 'path', 'polygon', 'polyline', 'rect', 'script', 'set', 'source', 'stop', 'style', 'track', 'use', 'wbr', '{#', '{%', '{{' at 6:1	parse_error

Probably that's not the best example, but something like

{% if is_div %}
<div>
{% endif %}

Test

{% if is_div %}
</div>
{% endif %}

will also fail
