Syck dies on multiline regex

[Josh Cheek]

[Note: parts of this message were removed to make it a legal post.]

require 'yaml'
[YAML, Marshal].each do |serializer|
[/ab/x, /a
b/x].each do |regex|
begin
serializer.load(serializer.dump regex)
rescue
p $!
end
end
end

# >> #<Syck::TypeError: Invalid Regular expression: "/a\n b/x">



This, in tandem with a few other things, cost me about four hours today (and
made me reconsider my decision to become a nonsmoker -.-).

Is this a bug? If so, where should I report it?

It is probably a bug. It _probably_ won't ever get fixed as nobody =
really maintains syck anymore (tho if you come up with a patch, that'd =
certainly help). Try psych if it is possible:

6371 % ruby19 -rpsych -ryaml -e 'p YAML.dump /a
b/x'
"--- !ruby/regexp \"/a\\n b/x\"\n"

Probably.

If so, where should I report it?

Though, as noted, syck is not maintained and psych appears to be the future=
