IwaiEngine.jl

Jinja-like template engine for Julia.

IwaiEngine compiles templates to Julia functions. It supports a compact Jinja-style syntax while staying fast enough for server-side rendering workloads.

Features

• {{ expr }} expressions
• {% if %}, {% elif %}, {% else %}, {% end %}
• {% for x in xs %} ... {% end %} with loop.index, loop.index0, loop.first, loop.last, loop.length
• {% set name = expr %}
• {% include "partial.iwai" %}
• {% extends "base.iwai" %} and {% block name %} ... {% end %}
• {% autoescape false %} ... {% end %}
• {# comment #} and {% raw %} ... {% endraw %}
• filters such as upper, lower, trim, length, join, default, escape, safe

Installation

Quick Start

using IwaiEngine

template = IwaiEngine.parse("""
<ul>
{% for team in teams %}
  <li>{{ loop.index }}. {{ team.name }} - {{ team.score }}</li>
{% end %}
</ul>
""")

template((
    teams = [
        (name = "Jiangsu", score = 43),
        (name = "Beijing", score = 27),
    ],
))

"<ul>\n\n  <li>1. Jiangsu - 43</li>\n\n  <li>2. Beijing - 27</li>\n\n</ul>\n"
