Usage

Example

Let's make our crystal init template.

Template structure

• spec/
  • .gitignore
  • spec_helper.cr.ecr
  • {{file}}_spec.cr.ecr
• src/
  • {{file}}/
    • version.cr.ecr
  • {{file}}.cr.ecr
• .travis.yml
• LICENSE.ecr
• README.md.ecr
• shard.yml.ecr

Template file example

# shard.yml.ecr
name: <%= @file %>
version: 0.1.0

authors:
  - <%= @author %>

license: MIT

Template class definition

class CrystalInitTemplate < Teeplate::FileTree
  directory "#{__DIR__}/path/to/template"

  @file : String
  @class : String
  @author : String
  @year : Int32

  def initialize(out_dir, @file, @class, @author, @year)
    super out_dir
  end
end

Here we go!

CrystalInitTemplate.new("/path/to/output", "teeplate", "Teeplate", "mosop", 2016).render

Output structure

Overwriting

Forced

class Template < Teeplate::FileTree
  directory "/path/to/template"

  @face : String

  def initialize(out_dir, @face)
    super out_dir
  end
end

Template.new("/path/to/output", ":)").render
Template.new("/path/to/output", ":(").render(force: true) # files to be overwritten
Template.new("/path/to/output", ":P").render # nothing happens

Interactive (WIP)
