Haml2phlex

A haml 2 phlex converter. haml and phlex are both used to render ruby views. See phlex here

Why Phlex?

• less context switching between haml and ruby leads to easier onboarding and developer happiness
• Much faster times as the ruby code gets JIT compiled
• Less files that are more meaningful and organized through splitting the html components into functions.
• Able to utilize Object Oriented Programming. When you need it, you need it.

Installation

Add this to your application's Gemfile:

group :development do
    gem 'haml2phlex'
end

And then execute:

$ bundle install

Or install it yourself as:

$ gem install haml2phlex

Usage

convert from HAML to Phlex.

this is an imperfect string-parsing-based converter from HAML to Phlex on a subset of HAML functionality most commonly used.

this means results still need to be touched up before they are actually usable. However - this will get rid of most the grunt work.

use as so in the rails console to output to the command line so you can copy paste:

x = Haml2phlex::Haml2flex.new('user_customizes/_show.html.haml', spacer: "\t", base_root: "app/views/")
puts x.out

or to output to a corresponding file with class definitions etc. (in this case app/views/user_customizes/show.rb)

x = Haml2phlex::Haml2flex.new('user_customizes/_show.html.haml', spacer: "\t", base_root: "app/views/")
x.to_file

Example Input

 = form_for @user_customize do |f|
 	- if @user_customize.errors.any?
 		#error_explanation
 			%h2= "#{pluralize(@user_customize.errors.count, "error")} prohibited this user_customize from being saved:"
 			%ul
 				- @user_customize.errors.full_messages.each do |message|
 					%li= message

 	.actions
 		= f.submit 'Save'

Example Output

form_for @user_customize do |f|
    if @user_customize.errors.any?
    	div(:id=>"error_explanation") {
			h2() { "#{pluralize(@user_customize.errors.count, "error")} prohibited this user_customize from being saved:" } 
			ul() {
				@user_customize.errors.full_messages.each do |message|
					li() { message } 
				end
			}
		}
	end
	div(:class=>"actions") {
		f.submit 'Save'
	}
end

Options

since 1.0.13 if you have a template method in your ApplicationView, the to_file function will acommidate that with a super do .... end. This lets you do something like the below in your ApplicationView.

def template(&)
	t = Time.now 
	yield
	Rails.logger.info "#{self.class.to_s} Phlex class took #{(Time.now - t) * 1000} ms"
end

Needless to say, this is nice for comparing timing with previous haml implementations

Development

After checking out the repo, run bin/setup to install dependencies. 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 the created tag, and push the .gem file to rubygems.org.
