ANTLR, Dynamic variables
- by JTS
Hello,
I have an ANTLR grammar that can parse and evaluate simple expressions like 1+2*4, etc.
What I would like to do is to evaluate expressions like 2+$a-$b/4 where the $ variables are dynamic variables, that come from an external source and are continuously updated.
Is there any design pattern on how to do this using ANTLR, best practices, etc?
Shall I "substring" the $a with the updated value ($a - 4.34)
A nicer way to do this?
Thx
