trim-template
is an HTML templating engine for Python inspired by Ruby's Slim template engine.
The objective behind Trim is to simplify template syntax to a minimal format that, like Python itself,
makes use of indentation to indicate how blocks of code should be interpreted.
pip install trim-template
doctype strict
html
head
title My HTML title
stylesheet src='/some.css'
javascript:
console.log('embedded JS inside the template');
body
css:
.alert { color: 'red'; }
.menu-bar
- if user.logged_in
img src={user.profile.image_path}
- else
a#login-button.btn.btn-primary href={login_path} Login
.alert
h1 {greeting}
p.exciting This is the first ever Python Trim-Template
h2#member-list Members
form
input type='checkbox' disabled=True checked=True
p
ul
- for user in users
li
/ code comment - show the user's names. This line will not render.
span {user.first_name} {user.last_name}
/! render the footer
#footer Thanks for using Trim!
Trim-Template will render the above template into HTML, as below:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
<head>
<title>My HTML title</title>
<stylesheet src="/some.css"></stylesheet>
<script type='javascript'>
console.log('embedded JS inside the template');
</script>
</head>
<body>
<style>
.alert { color: 'red'; }
</style>
<div class="menu-bar">
<a class="btn btn-primary" href="/auth/login" id="login-button"/>Login</a>
</div>
<div class="alert">
<h1>Hello World!</h1>
</div>
<p class="exciting">
This is the first ever Python Trim-Template
</p>
<h2 id='member-list'>Members</h2>
<form>
<input type="checkbox" disabled="disabled" checked="checked"/>
</form>
<p>
<ul>
<li>
<span>Stephen Colber</span>
</li>
<li>
<span>Bob Marley</span>
</li>
<li>
<span>Charlie Chaplin</span>

from trim_template.trim import TrimTemplate
tmpl = TrimTemplate("file.html.trim")
