[antlr-interest] StringTemplate question

[Varun Bhargava]

Hi All,

 

I have the following rule in my grammar:

 

A : B (('AND' | 'OR') B)* ;

 

B : C '=' D

 

Where C is an identifier and D is a string literal

 

If D is an empty string, I do not want to output the the B rule at all
and also want to get rid of the dangling 'AND' or 'OR'.

 

So for example if my expressions is

 

Var1 = 'val1' AND Var2 = '' 

 

I want to output

 

Var1 = 'val1'

 

How can this be achieved using stringtemplate?

 

Thanks

Varun
