Kilt

Generic templating interface for Crystal.

Goal

Simplify developers' lives by abstracting template rendering for multiple template languages.

Supported out of the box

| Language | File extensions | Required libraries | Maintainer | | -------- | --------------- | ------------------ | ---------- | | ECR | .ecr | none (part of the stdlib) | | | Mustache | .mustache | crustache | @MakeNowJust | | Slang | .slang | slang | @jeromegn |

Installation

Add this to your application's shard.yml:

dependencies:
  kilt:
    github: jeromegn/kilt
  
  # Any other template languages Crystal shard

Usage

• Kilt essentially adds two macros Kilt.embed and Kilt.file, the code is really simple.
• Add template language dependencies, as listed in the support table above.

Both macros take a filename and a io_name (the latter defaults to "__kilt_io__")

Example

require "kilt"

# For slang, add:
require "kilt/slang"

# With a Class

class YourView
  Kilt.file("path/to/template.ecr") # Adds a to_s method
end
puts YourView.new.to_s # => <compiled template>


# Embedded

str = Kilt.render "path/to/template.slang"

# or

str = String.build do |__kilt_io__|
  Kilt.embed "path/to/template.slang"
end

puts str # => <compiled template>

Registering your own template engine

Use Kilt.register_engine(extension, embed_command) macro:

require "kilt"

module MyEngine
  macro embed(filename, io_name)
    # ....
  end
end

Kilt.register_engine("myeng", MyEngine.embed)

This can be part of your own my-engine library: in this case it should depend on kilt directly, or this could be a part of adapter library, like: kilt-my-engine, which will depend on both kilt and my-engine.
