Amber is an elegant templating engine for Go Programming Language
It is inspired from HAML and Jade
Tags
A tag is simply a word:
html
is converted to
<html></html>
It is possible to add ID and CLASS attributes to tags:
div#main
span.time
are converted to
<div id="main"></div>
<span class="time"></span>
Any arbitrary attribute name / value pair can be added this way:
a[href="http://www.google.com"]
You can mix multiple attributes together
a#someid[href="/"][title="Main Page"].main.link Click Link
gets converted to
<a id="someid" class="main link" href="/" title="Main Page">Click Link</a>
It is also possible to define these attributes within the block of a tag
a
#someid
[href="/"]
[title="Main Page"]
.main
.link
| Click Link
Doctypes
To add a doctype, use
!!! or
doctype keywords:
!!! transitional
// <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
or use
doctype
doctype 5
// <!DOCTYPE html>
Available options:
5,
default,
xml,
transitional,
strict,
frameset,
1.1,
basic,
mobile
Tag Content
For single line tag text, you can just append the text after tag name:
p Testing!
would yield
<p>Testing!</p>
For multi line tag text, or nested tags, use indentation:
html
head
title Page Title
body
div#content
p
| This is a long page content
| These lines are all part of the parent p
a[href="/"] Go To Main Page
Data
Input template data can be reached by key names directly. For example, assuming the template has been
executed with following JSON data:
{
"Name": "Ekin",
"LastName": "Koc",
"Repositories": [
"amber",
"dateformat"
],
"Avatar": "/images/ekin.jpg",
"Friends": 17
}
It is possible to interpolate fields using
#{}
p Welcome #{Name}!
would print
<p>Welcome Ekin!</p>
Attributes can have field names as well
a[title=Name][href="/ekin.koc"]
would print
<a title="Ekin" href="/ekin.koc"></a>
Expressions
Amber can expand basic expressions. For example, it is possible to concatenate strings with + operator:
p Welcome #{Name + " " + LastName}
Arithmetic expressions are also supported:
p You need #{50 - Friends} more friends to reach 50!
Expressions can be used within attributes
img[alt=Name + " " + LastName][src=Avatar]
