Ate

Atractive Template Engine for minimalist people

Installation

$ gem install ate

Usage

template = Ate.parse("Hello World")
template.render #=> "Hello World"

Ruby code

Lines that start with % are evaluated as Ruby code.

% if true
  Hi
% else
  No, I won't display me
% end

As this is ruby code, you can comment as you has always done

% # I'm a comment.

And you can still doing any ruby thing: blocks, loops, etc.

% 3.times do |i|
  {{i}}
% end

Assignment

To print a variable just use {{ and }}

Send Variables

Send a variables as a hash in the parse method to the template so it can get them:

template = Ate.parse("Hello, this is {{user}}", user: "dog")
template.render #=> "Hello, this is dog"

Also, you can send other kinds of variables:

template = <<-EOT
  % items.each do |item|
    {{ item }}
  % end
EOT
parsed = Ate.parse(template, items: ["a", "b", "c"])
parsed.render #=> "a\nb\n\c"

You can even take advantage of do whatever operation inside the {{ }}

template = Ate.parse("The new price is: {{ price + 10 }}", price: 30)
template.render #=> "The new price is: 40"

Contexts

For send a particular context to your template, use the context key

user = User.new "Julio"
puts user.name #=> "Julio"
template = Ate.parse("Hi, I'm {{ context.name }}", context: user)
template.render #=> "Hi, I'm Julio"

Using files

Declare you file with .ate extension in the parse method

template = Ate.parse("example.ate")

Feel free to use any markup language like HTML

template = <<-EOT
  <h1>{{ main_title }}</h1>
  % posts.each do |post|
    <article>...</article>
  % end
EOT
parsed = Ate.parse(template, main_title: "h1 title!", posts: array_of_posts)
