Ragel: How to return different values by matching different expressions

Question

I'm looking for a function that returns different integer values by matching an input string for different expressions.

Here is how it could be, but syntax:

package main

func MatchType(data []byte) int {
  %% machine scanner;
  %% write data;

  cs, p, pe, eof := 0, 0, len(data), len(data)

  _ = eof

  %%{
    main := (  0..120 '-first-' ) @{ return 1 } ;
    main := ( 0..120 '-second-' ) @{ return 2 } ;

    write init;
    write exec;
  }%%

  return -1
}

Can anybody please advise?

Answer 1

  %%{

    action a1 { return 8; }
    action a2 { return 10; }

    main := ( 0..120 '-first-' $a1  | 0..120 '-second-' $a2 ) @{ return 0 } ;

    write init;
    write exec;
  }%%
