Hi All!

I need to parse a piece Ruby source code file. For that purpose, I need  
a Ruby parser (which can be used on windows plateform). I tried to  
configure ruby\_parser 1.0, but I am unable to configure it on windows  
XP, as it is depending upon RACC parser, which can be installed in unix  
operating system. Any simple to use Ruby parse will be a great help.

Thanks in advance to ALL.

Bye

ParseTree comes precompiled for windows, is faster, and does the exact  
same thing as ruby\_parser.

If you’re truly adventurous you could try to download the win32 mingw  
sandbox  
[http://rubyinstaller.rubyforge.org/wiki/wiki.pl?Mingw](http://rubyinstaller.rubyforge.org/wiki/wiki.pl?Mingw)  
and then install a mingw version of RACC.  
Good luck with that.

Hi Daniel!

Thanks for helping me. I am able to install ParseTree on my windows  
system. Further, it also requirs RubyInline, so I also installed it. But  
I am still unable to run a simple example of parse tree so far.

I read in it documentations that

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]]]]]

But how can I get this output. I am unable to do so. Actually I am  
farely new to Ruby & specially parsing. Further, I have to run this  
parser on Rails but no way yet. I am not able to run a simple example of  
parsetree. I study much material about parsing but donot have a clue  
that how to get the above output of the source file. I will be very  
thankful,if you can guide me with a very simple example how to use  
parsetree to get above output. I am waiting your kind reply.

Bye
