Suggestion for improvement in formatting of output in GTMStackTrace #45

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
With OSX 10.6, the callStackSymbols call gives a nicely formatted stack
trace, whereas the GTM one is a bit hard to read because of not handling
the length of 64 bit frame addresses, and using the full paths to
executables, and some formatting issues. I therefore altered the formatting
to match what callStackSymbols gives as follows:

static NSString *GTMStackTraceFromAddressDescriptors(struct
GTMAddressDescriptor descs[],
                                                     NSUInteger count) {
    NSMutableString *trace = [NSMutableString string];

    for (NSUInteger i = 0; i < count; i++) {
        // Newline between all the lines
        if (i) {
            [trace appendString:@"\n"];
        }
        if (descs[i].class_name) {
            [trace appendFormat:@"%-2u %-35s %#016lx %s[%s %s]",
             i, 
             (descs[i].filename ? [[[NSString stringWithCString:descs[i].filename
encoding:NSUTF8StringEncoding] lastPathComponent]
cStringUsingEncoding:NSUTF8StringEncoding] : "??"),
             descs[i].address, 
             (descs[i].is_class_method ? "+" : "-"),
             descs[i].class_name,
             (descs[i].symbol ? descs[i].symbol : "??")];
        } else {
            [trace appendFormat:@"%-2u %-35s %#016lx %s()",
             i, 
             (descs[i].filename ? [[[NSString stringWithCString:descs[i].filename
encoding:NSUTF8StringEncoding] lastPathComponent]
cStringUsingEncoding:NSUTF8StringEncoding] : "??"),
             descs[i].address,
             (descs[i].symbol ? descs[i].symbol : "??")];
        }
    }
    return trace;
}

I hope this is of some use to improve the source.
