Saving YAML data

ruby-talk
1

Hi

I've just started playing with YAML but am having problems saveing the file. What I can work out from the docs is that I should use something like:-

require 'yaml'
y = YAML.Store.new( "./yaml.store.1", :Indent => 2, :Separator => '---.pstore' )

however when I do this in irb I get

irb(main):001:0> require 'yaml'
=> true
irb(main):002:0> y = YAML.Store.new( "./yaml.store.1", :Indent => 2, :Separator => '---.pstore' )
NoMethodError: undefined method `Store' for YAML:Module
        from (irb):2
irb(main):003:0>

Anyone know what I'm doing wrong.

Cheers

This is what I usually use:

File.open('filename', 'w+b') {|file| YAML.dump my_data, file}

you are trying to call the 'Store' method of the YAML module with 'YAML.Store'

YAML::Store

. signifies calling a method.

Thanks, that seems to do what I want.

With ref to the other solution for some reason I still get

irb(main):051:0* require 'yaml'
=> false
irb(main):052:0> y = YAML::Store.new( "./yaml.store.1", :Indent => 2, :Separator => '---.pstore' )
NameError: uninitialized constant YAML::Store
        from (irb):52
irb(main):053:0>

But I have a result that works

Cheers

Try "require 'yaml/store'", and it should work. The YAML::Store
functionality is defined in a separate place, and isn't required with
just "require 'yaml'".

HTH,
