YAML misformats hash with ruby object as key

Backport #1331: YAML misformats hash with ruby object as key

Added by bahuvrihi (Simon Chiang) over 17 years ago. Updated about 7 years ago.

Status:
Closed
Assignee:

Description

=begin
YAML misformats the dump of hashes where the key is a user-defined ruby object. For instance:

class A; end
YAML.dump({A.new => :a})

Produces:

!ruby/object:A ? {}
: :a

Which cannot be reloaded as YAML because the question mark is in the wrong place. The correctly formatted YAML is:

? !ruby/object:A {}
: :a

I have attached a couple tests with a patch illustrating how to work around this problem using gsub. Obviously a string substitution is not a long term solution, but I hope it illustrates what needs to be fixed.

=begin
This bug still exists in ruby 1.8.7 (2011-02-18 patchlevel 334). Is there a known fix or workaround that I can use? The gsub suggested by Simon seems a bit brittle.
