Problem with yaml and lines beginning with a colon

[Xavier]

Hi all,

For some reason, yaml reads strings beginning with a colon as symbols
which leads to 'cannot dup symbol' exceptions.

$ ruby -v
ruby 1.8.1 (2004-04-24) [i686-linux-gnu]

$ irb
irb(main):001:0> require 'yaml'
=> true
irb(main):002:0> YAML::load(" :0 local".to_yaml)
=> " :0 local"
irb(main):003:0> YAML::load(":0 local".to_yaml)
=> :"0 local"

Note the first string has a leading space and the second has not. The
latter is not read back correctly.


Is this is a bug?
Does anyone know a workaround?

Thanks.

This is a bug in Ruby CVS. Has been since Apr 3. For now, you can
checkout a copy of 1.8 previous to that (including the 1.8.1 release).
I'll report back when I have a fix.

You remark helped me locate where strings with a leading colon
become a symbol. I'll just remove that bit until the problem is fixed. I
know I will not use symbols.


Thanks for your support.

Just wanted to followup and say that this is fixed in CVS. Symbol
loading is much improved now. Thankyou.
