ParseTree version 3.0.2 has been released!

- [http://rubyforge.org/projects/parsetree/](http://rubyforge.org/projects/parsetree/)

ParseTree is a C extension (using RubyInline) that extracts the parse  
tree for an entire class or a specific method and returns it as a  
s-expression (aka sexp) using ruby’s arrays, strings, symbols, and  
integers.

As an example:

def conditional1(arg1)  
if arg1 == 0 then  
return 1  
end  
return 0  
end

becomes:

[:defn,  
:conditional1,  
[:scope,  
[:block,  
[:args, :arg1],  
[:if,  
[:call, [:lvar, :arg1], :==, [:array, [:lit, 0]]],  
[:return, [:lit, 1]],  
nil],  
[:return, [:lit, 0]]]]]

Hi,

I just tried installing ParseTree from a gem and keep getting the  
message  
ERROR: could not find gem ruby\_ParseTree locally or in a repository

Is the gem missing? Other gems (ruby2ruby, ruby\_parser) install fine.

Thanks  
Ed

seems fine on my end… the name it is reporting is suspect.
