"extends" in ede templates

[Andreas Reuleaux]

Hi Brendan, Hi mailinglist,

I came across your Haskell ede templates coming from servant,
and servant-ede in particular:

https://hackage.haskell.org/package/servant-ede
https://github.com/alpmestan/servant-ede

and I got some simple examples running (within servant) similar
to those in

https://github.com/alpmestan/servant-ede/tree/master/example

and of course I can play with ede on the ghci repl.
Well, thanks for creating ede in the first place
(and I am therefore CC'ing to the haskell-servant mailing list as well).

Now, I see that one ede template can "include" other ones as explained
in http://brendanhay.nz/ede/Text-EDE.html, in the section "Includes",
but - coming from other templating systems in Python etc. - it appears
to me, that it is not currently possible that one template "extends"
another one. Is this true?

I assume you know what I mean by extending, but two links nevertheless
for better explanations / examples:

* you mentioned ede templates being similar to Jinja2 and Liquid
templates. - Well Jinja2 templates know how extend another one, cf.

http://jinja.pocoo.org/docs/2.9/templates/#template-inheritance

"[...] a child template might look like this:"

{% extends "base.html" %}
{% block title %}Index{% endblock %}
{% block head %}
{{ super() }}
<style type="text/css">
.important { color: #336699; }
</style>
{% endblock %}
{% block content %}
<h1>Index</h1>
<p class="important">
Welcome to my awesome homepage.
</p>
{% endblock %}



* I also found an interesting discussion about "extension" of mustache
(hastache) templates

https://stackoverflow.com/questions/7925931/can-mustache-templates-do-template-extension

which seem similar to ede to me (right?)


I wonder, if it possible / difficult / foreseen to add templates
extension to ede?, any advice on a workaround?

Thanks in advance,
Andreas
