Subject: Help with using Ri() and VIM


I have installed Ri and am finding it very helpful... I found out about it 
through a blurb in "The Ruby Developer's Guide", which also included the 
following vim macro to use from within vim:

---

function Ri()
 
let b:x = system("ri '" . input("ri: ") . "' > /tmp/ri_output")
 
sp /tmp/ri_output
 
endfunction
 
map <F2> :call Ri()<CR>

---

I did this, but when I hit <f2> and then enter the object to explore I get 
the following error:

---

ri: Array Error detected while processing function Ri:
Unknown function: system
Invalid expression:  system("ri '" . input("ri: ") . "' > /tmp/ri_output")
"/tmp/ri_output" [New File]

---

I am pretty clueless about vim macros, and though this might not be the 
best place to post this am hoping some of you have this woking and can 
provide a solution. 

So, any ideas whats wrong?

Thanks!
Andy
