latex - Vim: How do I tell where a function is defined? ( -

I set up yesterday and today I have established.

Calling a broken function from the menu items ( TeX-Suite -> Views ).

When I click on the menu, it calls:

 : Quiet! Call Tex_ViewLatex ()  

Question: Where can I get that function?

---

Just for curiosity I removed the quiet part and ran it:

 : Tex_ViewLatex ()  

Call:

error detected while processing the function Tex_ViewLaTeX: line 34: E121: undefined variable: s: viewer E116: strlen (s: viewer for invalid argument function) ) E15: Invalid expression: strlen (s: viewer) line 39: E121: undefined variable: appOpt E15: Invalid expression: 'open' .appOpt.s: viewer. '$ *. 'S: Goal Line 79: E 121: Irreversible Variable: Explanation E 116: Invalid Argument for Function Option (Explanation,' \ V $ * ', Mainfam,' G ') E15: Invalid Expression: Option (ExtSt string, V $ * ', mainfname,' g '), line 80: E121: Undefined variables: execString E116: Invalid argument for function Tex_Debug line 82: E121: Undefined variable: execString E15: Invalid expression:' Silent! ! Hold 'excelstring' or type command to continue

I suspect that if I can see the source functions, then I could have figured out which inputs are bad or its What is looking for.

Use: verbose prefix command:

 : Verbose function Tex_ViewLaTeX 

In the second line of output (just above the function's body) is the location where the function was defined.
