Versioning of external extensions?

[Jason Harris]

Ahhh!!! Thanks!!!

Thats what I was looking for!

If I can push my luck, can I ask for the cases when it returns 1, is there a pattern I can use to where the results / warnings are sent to? Ie are the "unresolved files" warnings sent to stderr (instead of stdout)? Is the "nothing to do" message sent to stderr or stdout? Is there something that we GUI writers should do here...

I had switched to the following within MacHg (This is in objective-C so the bits [obj method:arg] syntax might seem strange if you have never seen it before...)

- (BOOL) hasErrors
{
    return ( result_ == 1 && IsNotEmpty(errStr_)) || result_ > 1 ||
             result_ < 0 || [errStr_ isMatchedByRegex:@"^(?i)abort" options:RKLMultiline];
}
- (BOOL) hasWarnings
{
    return IsNotEmpty(errStr_) && ![self hasErrors];
}
- (BOOL) hasNoErrors
{
    return ![self hasErrors];
}
- (BOOL) isClean
{
    return result_ == 0 && IsEmpty(errStr_);
}

Cheers,
  Jason
