§223 ANNOYANCE-FILTER MAIN PROGRAM 181
223. Main program.
The main program is rather simple. We initialise the global variables then chew through the command
line, doing whatever the options request.
〈 Main program 223 〉 ≡
〈 Global declarations used by component in temporary jig 253 〉;
int main (int argc, char ∗argv [ ])
{
int opt ;
〈 Initialise global variables 224 〉;
〈 Process command-line options 243 〉;
#ifdef POP3_PROXY_SERVER
if (popProxyServer ≠ "") {
〈 Operate POP3 proxy server, filtering replies 218 〉;
}
#endif
return exitStatus ;
}
This code is used in section 254.
224.
〈 Initialise global variables 224 〉 ≡
memset (messageCount , 0, sizeof messageCount );
isoToken .setISO 8859defaults (minTokenLength , maxTokenLength );
asciiToken .setUS ASCIIdefaults (streamMinTokenLength , streamMaxTokenLength );
This code is used in section 223.
225. The master dictionary is global to the main program and all of its support functions. It’s
declared after all the class definitions it requires. We also support a fastDictionary for classification
runs. If loaded, it takes precedence over any loaded dictionary.
〈 Master dictionary 225 〉 ≡
static dictionary dict ; /∗ Master dictionary ∗/
static fastDictionary fDict ; /∗ Fast dictionary ∗/
See also section 249.
This code is used in section 254.
226.
〈 Global variables 226 〉 ≡
static unsigned int messageCount [2]; /∗ Total messages per category ∗/
static list〈string〉 messageTranscript ; /∗ Message transcript list ∗/
static queue〈string〉 parserDiagnostics ; /∗ List of diagnostics generated by the parser ∗/
static bool saveParserDiagnostics = false ; /∗ Save parser diagnostics in parserDiagnostics ? ∗/
