HTML is a Programming Language!
html-lang
is experimental and currently in development. Proceed at your own risk!
html-lang
features no build step, no bundling, no webpack configs. Open up your HTML and start writing HTML.
Install
Include the script tag into the <head></head>
section of your HTML.
<script src="https://unpkg.com/@joelnet/html-lang@0.0.6/umd/html-lang.js"></script>
Variables
Variables are globally scoped.
<!-- String -->
<val message="Hello World"></val>
<!-- Number -->
<val x:number="888"></val>
<!-- Object -->
<val y:object="{ x: 1, y: 2 }"></val>
<!-- Array -->
<val z:object="['A', 'B', 'C']"></val>
Computed Values
The computed value syntax has a :?
at the end of the Variable name.
<!-- Set name -->
<val name="World"></val>
<!-- Compute Message -->
<val message:?="'Hello ' + name"></val>
Output
Display a Variable
<!-- set message to "Hello World" -->
<val message="Hello World"></val>
<!-- Display message -->
<span set:text="message"></span>
If / Conditional
<if test="x > 10">X is GREATER than 10!</if>
An else
can be simulated by negating the if condition.
<if test="x > 10">X is GREATER than 10!</if>
<if test="!(x > 10)">X is NOT GREATER than 10!</if>
Loops
<!-- set i to 1 -->
<val i:number="1"></val>
<!-- loop while i is less than 11 -->
<while test="i < 11">
<!-- display i -->
<div set:text="i"></div>
<!-- increment i -->
<val i:?="i+1"></val>
</while>
Fetching Data
<!-- fetch data -->
<val response:fetch="'https://swapi.dev/api/people/1'"></val>
<!-- destructure response into loading, error, data -->
<val
loading:?="response.loading"
error:?="response.error"
data:?="response.json"
></val>
<!-- Show when Loading -->
<if test="loading">Loading...</if>
<!-- Show if Error -->
<if test="error"> Error: <span set:text="error"></span> </if>

Examples
FizzBuzz
<!-- set i to 1 -->
<val i:number="1"></val>
<!-- loop to 100 -->
<while test="i < 101">
<div>
<!-- if no match display i -->
<if test="i % 3 !== 0 && i % 5 !== 0">
<span set:text="i"></span>
</if>
<!-- display Fizz, Buzz -->
<if test="i % 3 === 0">Fizz</if><if test="i % 5 === 0">Buzz</if>
