parsetree (3.0.5) is Failing
for Seamus Abshere (GNU/Linux, about 1 year ago)

At my company, we were able to <a href="http://numbers.brighterplanet.com/2010/12/17/replacing-parsetree-in-ruby-1-9">replace ParseTree with sourcify in Ruby 1.9</a>.

<pre><code>
# Ruby 1.8 with ParseTree
proc.to_ruby
# Ruby 1.9 with sourcify (may raise NoMatchingProcError or MultipleMatchingProcsPerLineError)
proc.to_source
# Ruby 1.9 with sourcify (help it find the right Proc)
proc.to_source :attached_to => :name_of_proc
</code></pre>

Fails with error "ParseTree doesn't work with ruby 1.9.1 (LoadError)"

There's no way what Konstantin said is accurate.

parsetree (3.0.3) is Failing
for ash (Mac OSX, over 3 years ago)

Try running: ruby1.9 -rparse_tree -e '1'

It won't work. ParseTree checks if your using ruby1.9 and throws an error:
