# Effigie
[](https://travis-ci.com/mberlanda/effigie) [](https://badge.fury.io/rb/effigie)
Simple utility to render ERB templates from hash, objects or self.
Mostly inspired to SO
## Installation
Add this line to your application's Gemfile:
```ruby
gem 'effigie'
```
And then execute:
$ bundle
Or install it yourself as:
$ gem install effigie
## Usage
### Using a static file and the default template:
Template under `tasks.erb`:
```erb
These are my tasks:
<% tasks.each do |t| %>* <%= t.name %>: <%= t.due_date %>
<% end %>
```
```rb
Task = Struct.new(:name, :due_date)
template = Effigie::Template.new(filepath)
tasks_list = [Task.new('foo', 'today'), Task.new('bar', 'tomorrow')]
# Using an object responding to these methods
class Agenda
attr_accessor :tasks
end
agenda = Agenda.new.tap { |a| a.tasks = tasks_list }
template.render(agenda)
# Using an OpenStruct
template.render(OpenStruct.new(tasks: tasks_list))
# Using self
def tasks
tasks_list
end
template.render(self)
# Using an Effigie::HashBinding
template.render(Effigie::HashBinding.new(tasks: tasks_list))
```
### Using custom subclasses
```rb
# Override default erb private method to avoid reading from file
class HelloTemplate < Effigie::Template
def erb
ERB.new("Hello <%= name %>")
end
end
Person = Struct.new(:name)
HelloWorldTemplate.new.render(Person.new("John Doe"))
# Read from instance variables and methods
class UserTemplate < Effigie::Template
def erb
ERB.new("Hello <%= current_user.name %>, welcome into <%= @application %>.")
end
end
def current_user
Person.new("John Doe")
end
@application = "Effigie"
UserTemplate.new.render(self)
# Read from an hash table
class HashTemplate < Effigie::Template
def erb
ERB.new("Hello <%= self[:name] %>, welcome into <%= self[:application] %>.")
end
end
HashTemplate.new.render(name: "John Doe", application: "Effigie")
```
## Development
After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
