Description
index_ variable is a map that holds the arguments that are added using addArgument.
The exists function is currently written as follows
bool exists(const String& name) const { return index_.count(delimit(name)) > 0; }
so a code like the one below will always enter the if's body, even if the clean argument has not been sent to the program,
parser.addArgument("-c", "--clean");
// parsing passed arguments
parser.parse(size_t(__argc), const_cast<const char **>(__argv));
if (parser.exists("clean")) {
// ...
}
This is inconsistent with the definition given for the exists function
exists() check if an argument has been found
Thank you for your efforts,
Sincerely,
Ahmad
