How to parse tokens into different text

[lthoerner]

I am writing a parser for my shell which needs to do two main things:

1. Parse a line of input to a tree structure
2. Parse certain tokens into different strings (a good example of this is that a "\\n" needs to be turned into a "\n")

Is there any way that I could do the second thing here without having to iterate over every parsed char after the whole thing has been parsed?

May be you can create a rule for your token, and create a rule my_any that you can use in place of ANY in the other rules:

token_new_line = {"\\n"}
my_any = { token_new_line | ANY }

You may need to adapt this, for example maybe it's not ANY but some other rule that you need. But I guess there is a pattern here.
