Saving with yaml

ruby-talk
1

Hi,

I have a question. :slight_smile: I have already found a lot in the web but that
does not really helped me. This far my code looks like this:

to save:

require "yaml"

@characters = ["Molly", "Trade"]
@saves = {location: "Southeaster",
聽聽hunger: 10,
聽聽life: 76
聽聽}
@settings = {display: "1360*960",
聽聽render: "high",
聽聽saves: "manual"
聽聽}

output = File.new("Saves.yaml", "w") do |file|
聽聽YAML.dump
end
output.write YAML.dump(@characters) # Wie sichert man mehrere
Sachen???
output.close

and to load:

require "yaml"

output = File.new("Saves.yaml", "r")
p YAML.load(output.read)
output.close

How can I save multiple array etc.?

It works but I want to save more than one hash, I want to save e.g. all
of them, but with that I can save just one or if I manage it to save all
three I can just load the first one.
So it would be nice if someone could help me. :slight_smile: Thanks

Yours faithfully
Greeneco

I'd probably just put them all in the same hash:

require "yaml"

filename = "data.yaml"
characters = ["Molly", "Trade"]
saves = {location: "Southeaster", hunger: 10, life: 76}
settings = {display: "1360*960", render: "high", saves: "manual"}
program_data = {characters: characters, saves: saves, settings: settings}

# File.write may not be in some older versions of Ruby
File.write filename, YAML.dump(program_data)

loaded_data = YAML.load(File.read filename)

require 'pp'
pp loaded_data
# >> {:characters=>["Molly", "Trade"],
# >> :saves=>{:location=>"Southeaster", :hunger=>10, :life=>76},
# >> :settings=>{:display=>"1360*960", :render=>"high", :saves=>"manual"}}

For example:
File.open("Saves.yaml", "w") do |file|
  file.write(YAML.dump(@characters))
  file.write(YAML.dump(@saves))
  file.write(YAML.dump(@settings))
end

or

File.open("Saves.yaml", "w") do |file|
  [@characters,@saves,@settings].each do |item|
    file.write(YAML.dump(item))
  end
end

or even better:

File.open("Saves.yaml", "w") do |file|
  file.write(YAML.dump([@characters,@saves,@settings]))
end
YAML.load File.read "Saves.yaml"
# => [["Molly", "Trade"], {:location=>"Southeaster", :hunger=>10,
:life=>76}, {:display=>"1360*960", :render=>"high", :saves=>"manual"}]
