Hi all,
in MimeType.cpp, some example sniffer rules are given:
Examples:
- 1.0 ('ABCD')
The file must start with the string "ABCD". The priority of the rule
is 1.0 (maximal).
- 0.8 [0:3] ('ABCD' | 'abcd')
The file must contain the string "ABCD" or "abcd" starting somewhere
in the first four bytes. The rule priority is 0.8.
- 0.5 ([0:3] 'ABCD' | [0:3] 'abcd' | [13] 'EFGH')
The file must contain the string "ABCD" or "abcd" starting somewhere
in the first four bytes or the string "EFGH" at position 13. The rule
priority is 0.5.
- 0.8 [0:3] ('ABCD' & 0xff00ffff | 'abcd' & 0xffff00ff)
The file must contain the string "A.CD" or "ab.d" (whereas "." is an
arbitrary character) starting somewhere in the first four bytes. The
rule priority is 0.8.
... what is wrong with this rule then:
0.9 ([0] '1BOF' & [0:32] "layer")
^ Sniffer pattern error: expected CharacterString,
found LeftBracket
Best regards,
-Stephan
