This works:
person : Hash(String, String) = {"name" => "John", "age" => "30", "city" => "New York"}
p person.to_json
In the second case, I get:
In src/bakerstreet.cr:51:23
51 | ARCHIVE = #{@dico.to_json}
^------
Error: undefined method 'to_json' for Hash(String, String)
This doesn’t work
require "path"
require "dir"
class Baker
def initialize(root : String)
@root = root
@root_path = Path.new(@root)
@arc = "archive.cr"
@dico = Hash(String, String).new
end
def to_path(file)
return @root_path.join(file).to_s
end
# URL to archive path mapping
def get_file_from_url?(url : String, bk, arc) : String
if url == "/" || url == ""
url = "/index.html"
end
begin
content = arc[bk.to_path(url)]
return content
rescue exception
return "File not found: #{bk.to_path(url)}"
end
end
# initialize the Hash '@dico'
def walk_files_and_directories(directory : String)
Dir.each_child(directory) do |entry|
path = File.join(directory, entry)
if File.directory?(path)
walk_files_and_directories(path)
else
content = File.read(path)
@dico[path.to_s] = content
end
end
end
# write 'archive' to disk
def make_archive
walk_files_and_directories(@root)
code_litteral = "

File.write(@arc, code_litteral)
end # def make_archive
