Oh god what have I done. A horrible starting point to an ELisp to DragonRuby Compiler.

el.rb

class Tokenizer
  attr_accessor :blocks, :current_token, :current_word, :root

  def initialize
    @id = 0
    @root = []
    @stack = [@root]
    @current_word = ""
  end

  def process token_char
    if token_char == ""
      # do nothing
    elsif (token_char == " " || token_char == "\n") && @current_word.strip.length > 0
      add_to_current_block @current_word if @current_word.strip.length > 0
      @current_word = ""
    elsif token_char == '('
      @stack.push([])
    elsif token_char == ')'
      add_to_current_block @current_word if @current_word.strip.length > 0
      add_to_current_block @stack.pop
      @current_word = ""
    else
      @current_word << token_char if token_char.strip.length > 0
    end
    puts "#{@root}"
  end

  def add_to_current_block word
    puts "adding #{word} to #{@stack[-1]}"
    @stack[-1] << word
    puts "#{@stack[-1]}"
  end
end

class El2Rb
  def self.compile! file
    El2Rb.new(file).compile!
  end

  def initialize file
    @file = file
    @code = $gtk.read_file file
    @tokenizer = Tokenizer.new
    $gtk.write_file "#{file}.rb", ""
  end

  def result_file
    "#{@file}.rb"
  end

  def compile!
    log_cyan "================== starting"
    idx = 0
    while idx < @code.length
      @tokenizer.process @code[idx]
      idx += 1
    end

    puts "#{@tokenizer.root}"
    log_cyan "================== complete"

    # todo convert root to ruby code and write it to file
    $gtk.require result_file
  end
end

main.el

(defun tick (args)
  (puts (str hello world)))

main.rb

require 'app/el.rb'

def tick args
  El2Rb.compile! "app/main.el" if args.state.tick_count == 0
end

$gtk.reset
