Toys
I just finished releasing a WHOLE bunch o' stuff, all gemified and cleaned up, mainly so that we could contribute the following solution to this week's ruby quiz (serializable procs):
require 'r2c_hacks'
class ProcStore # We have to have this because yaml calls allocate on Proc
def initialize(&proc)
@p = proc.to_ruby
end
def call(*args)
eval(@p).call(*args)
end
end
code = ProcStore.new { |x| return x+1 }
=> #<ProcStore:0x3db25c @p="proc do |x|\n return (x + 1)\nend">
OK, well, that obviously isn't the whole solution, but now that we've added Proc.to_ruby, it really is that simple. To see how simple it really is, check out our implementation:
class Proc
ProcStoreTmp = Class.new unless defined? ProcStoreTmp
def to_ruby
ProcStoreTmp.send(:define_method, :myproc, self)
m = ProcStoreTmp.new.method(:myproc)
result = m.to_ruby.sub!(/def myproc\(([^\)]+)\)/, 'proc do |\1|')
return result
end
end
We would have bypassed ProcStore entirely had we known how to get YAML to not call allocate on Proc when it was loading a proc back in. But, we were tired.
The Releases!

ParseTree 1.3.7 with:
+ 3 bug fixes:
