Slang

Very much inspired by slim, this is a templating language which outputs HTML.

Status

ALPHA -> No tests, no real-world usage, just playing with creating a nice parser/lexer that gives us slim-like templating capabilities.

Installation

Add this to your application's shard.yml:

dependencies:
  slang:
    github: jeromegn/slang

Usage

Known issue: macros don't work.

This does not work out of the box currently. There are known issues with the macros that prevent this from running correctly.

Rendering some slang to HTML

String.build do |str|
  embed_slang("path/to/file.slang", "str")
end

Syntax

span#some-id.classname
  #hello.world.world2
    span data-some-var=some_var
      span
        span.deep_nested
          = Process.pid
          | text node
          ' other text node syntax
    span.alongside pid=Process.pid
      custom-tag#with-id pid="#{Process.pid}"
        - strings.each do |s|
          span
            = s
#amazing-div some-attr="hello"

Given the context:

some_var = "hello"
strings = ["ah", "oh"]

Compiles to HTML:

<span id="some-id" class="classname">
  <div id="hello" class="world world2">
    <span data-some-var="hello">
      <span>
        <span class="deep_nested">
          12766
          text node
          other text node
        </span>
      </span>
    </span>
    <span class="alongside" pid="12766">
      <custom-tag id="with-id" pid="12766">

          <span>
            ah
          </span>

          <span>
            oh
          </span>

      </custom-tag>
    </span>
  </div>
</span>
<div id="amazing-div" some-attr="hello"></div>

Roadmap

• [ ] Documentation
• [ ] Tests
• [x] No need to rely on ECR probably, but that's optimization at this point
• [ ] Support "inline"
