Middleware information
This folder contains a middleware ported to Iris for a third-party package named pongo2.
More can be found here: https://github.com/flosch/pongo2
Description
pongo2 is the successor of pongo, a Django-syntax like templating-language.
Behaviour
- Entirely rewritten from the ground-up.
- Advanced C-like expressions.
- Complex function calls within expressions.
- Easy API to create new filters and tags (including parsing arguments)
- Additional features: 1. Macros including importing macros from other files (see template_tests/macro.tpl) 2. Template sandboxing (directory patterns, banned tags/filters)
Notes
<html><head><title>Our admins and users</title></head>
{# This is a short example to give you a quick overview of pongo2's syntax. #}
{% macro user_details(user, is_admin=false) %}
<div class="user_item">
<!-- Let's indicate a user's good karma -->
<h2 {% if (user.karma >= 40) || (user.karma > calc_avg_karma(userlist)+5) %}
class="karma-good"{% endif %}>
<!-- This will call user.String() automatically if available: -->
{{ user }}
</h2>
<!-- Will print a human-readable time duration like "3 weeks ago" -->
<p>This user registered {{ user.register_date|naturaltime }}.</p>
<!-- Let's allow the users to write down their biography using markdown;
we will only show the first 15 words as a preview -->
<p>The user's biography:</p>
<p>{{ user.biography|markdown|truncatewords_html:15 }}
<a href="/user/{{ user.id }}/">read more</a></p>
{% if is_admin %}<p>This user is an admin!</p>{% endif %}
</div>
{% endmacro %}
<body>
<!-- Make use of the macro defined above to avoid repetitive HTML code
since we want to use the same code for admins AND members -->
<h1>Our admins</h1>
{% for admin in adminlist %}
{{ user_details(admin, true) }}
{% endfor %}
<h1>Our members</h1>
{% for user in userlist %}
{{ user_details(user) }}
{% endfor %}
</body>
</html>
Usage
package main
import (
"github.com/kataras/iris"
"github.com/kataras/iris/middleware/pongo2"

func main() {
iris.Use(pongo2.Pongo2())
iris.Get("/", func(ctx *iris.Context) {
ctx.Set("template", "index.html")
ctx.Set("data", map[string]interface{}{"message": "Hello World!"})
})
iris.Listen(":8080")
