Integer matches

The integer pattern matches a string of numeric characters that may or may not be preceded by a minus sign. Any non-numeric character except for a dash (minus sign) is not valid for integer matches. The integer pattern matches the first part of the string:

For example, the following script matches each integer and the end-of-line. The match fails on the third line of data because there is a decimal point. At that point, the integer is matched with 214 and the pattern fails because eol is not a match for .56.

ASL Script (int_match.asl):
START {
 a:integer eol
}
do {
 print("Matched with ".a);
}
DEFAULT {
 ..eol
}
do {
 print("Failed match");
}
Input (int_match.txt):
12300
-375
214.56
Output:
$ sm_adapter --file=int_match.txt int_match.asl
Matched with 12300
Matched with -375
Failed match
