Idea for a trivial virtual file system for archiving text-based resources (html, css, js, etc. for a server)

Corresponding repository:

The idea is basically that it creates (from the resources folder) a file archive.cr which contains a Hash literal, which in turns holds the paths as keys and the file content as values.

The aim is embedding resource files in a desktop Webview-based app (in a OS independent manner).

require "path"
require "dir"
require "./archive.cr"

# TODO 1 make it recursive (tree structure)
# TODO 2 replace \n by a portable (OS dependent) newline symbol
# TODO 3 Test in combination with a server.
# TODO 4 Test on Windows.

Root      = Dir.new("public")
Root_path = Path.new("public")
Dico      = Hash(String, String).new
Arc       = "archive.cr"

def to_path(file)
  return Root_path.join(file).to_s
end

Root.each_child do |child|
  path = Root_path.join(child)
  content = File.read(path)
  Dico[path.to_s] = content.to_s
end

File.open(Arc, "w") do |file|
  file.print("def get_archive()
    \n\treturn Hash {\n\n")
end

File.open(Arc, "a") do |file|
  Dico.each_key do |key|
    token = %{"#{key}" => %{#{Dico[key]}}, \n}
    file.print(token)
    file.print("\n")
  end
end

File.open(Arc, "a") do |file|
  file.print("}")
end

File.open(Arc, "a") do |file|
  file.print("\n\nend")
end

arc = get_archive()

# arc.each do |item|
#     p item
#     puts "\n- - -\n"
# end

puts "file = #{arc[to_path("index.html")]}"

the (generated) archive.cr file looks like :

def get_archive() 
    
	return Hash {

"public/index.html" => %{<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">

</html>}, 

"public/two.html" => %{<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">

}

I improved the documentation for the “Bakerstreet” archiver;
