A Rakefile for making lispyscript projects. Needs 2 directories, src and bin

lispy_rake.rb

task default: [:make_all]

root = Dir.pwd
src = ENV["src"] || "src"; src_dir = File.join(root, src)
bin = ENV["bin"] || "bin"; bin_dir = File.join(root, bin)
main = ENV["main"] || "main"

def make(file_name, dir_out="bin")
  Dir.mkdir(dir_out) unless File.directory?(dir_out)
  res = `lispy #{file_name}.ls #{File.join(dir_out, file_name)}.js`
  puts res unless res.empty?
end

def make_all(files, dir_out="bin")
  files.each do |file|
    make(File.basename(file, ".ls"), dir_out)
  end
end

task :make_all do
  Dir.chdir(src_dir) do |path|
    puts "in #{path}"
    make_all(Dir.glob("*.ls"), bin_dir)
  end
end

task :clean do
  sh "rm #{bin_dir}/*"
end

task test: [:make_all] do
  sh "node #{File.join(root, bin, main)}.js"
end
