Thanks so much for your work!!

For assignment section: {% hmac 'SECRET', digest='sha1' as signature %}Hello world!{% endhmac %}. Here is the customized tag class:

import hmac
from jinja2_simple_tags import ContainerTag


class HMACExtension(ContainerTag):
    tags = {"hmac"}

    def render(self, secret, digest="sha256", caller=None):
        content = str(caller()).encode()

        if isinstance(secret, str):
            secret = secret.encode()

        signing = hmac.new(secret, content, digestmod=digest)
        return signing.hexdigest()

It seems the last line is required to return a string (i.e., signing.hexdigest()). Do you know if it is possible to be a complex object, such as a Pandas data frame?

Thanks!

When using ContainerTag, how to access tag contents?
I'd like to do something like this:

{% mytag "myarg" %}

this is some text

{% endmytag %}

I can access tag arguments, but can't figure out how to get to the tag's content ("this is some text") .

How does one go about creating a tag like this one?

{% tag() %}

{% else %}

{% endtag %}

Just wanted to say, thank you so much for this wrapper library!

This saved me so much effort trying to figure out how to use Jinja's extension system and does exactly what I needed.
(And thanks to @mikeabrahamsen for your blog post which led me here!)

Hi, I am very interested in using this but I can't figure out how to register it for FastAPI. Django made it so easy that I never had to really figure out how to register but I am running into issues when I create a tag and then try to use it elsewhere in my code.

Any tips would be much appreciated!

We use jinja2-simple-tags in a larger context of a website with Pelican and Markdown. Today I've found two issues when trying to use ContainerTag. They both lead to Unexpected end of template. Jinja was looking for the following tags: 'endmessage'. The innermost block that needs to be closed is 'message'.".

1. I cannot use my message tag as follows:

   {% message %}
   Some message.
   {% endmessage %}
   

   it must be inline

   {% message %}Some message.{% endmessage %}
   

   Adding an html tag also avoids the error:

   {% message %}
   <div>
   Some message.
   </div>
   {% endmessage %} 
   

2. If I put only a markdown link into the message, there must be a space before the closing tag, for example, {% message %}[Some message.](link) {% endmessage %}.

The details can be viewed in the original MR.

Here's my ContainerTag:

from jinja2_simple_tags import ContainerTag


class MessageExtension(ContainerTag):
    tags = {'message'}

    def render(self, title=None, size='is-normal', caller=None):
        header_template = '''
            <div class="message-header">
                <p>{title}</p>
            </div>
        '''
        message_template = '''
            <article class="message is-info {size}">
            {message_header}
            <div class="message-body">
                {message_body}
            </div>
            </article>
        '''

        message_header = ''
        if title:
            message_header = header_template.format(title=title)
        return message_template.format(
            size=size,
            message_header=message_header,
            message_body=caller()
        )

Hi and first of all thanks a lot for this project!

I am going to develop an equivalent of the InclusionTag as found in django-classy-tags based on this project.

I can either put it in an independent project or, if you are interested, contribute to this project.

I would, of course, follow your code styles, provide unit tests and be open to feedback.

What do you say?
