Multiple argument

[Xxproner]

Something like this :
cli_app -h "value1" -h "value2" -h "value3" ...
thx for advance!

There isn't an explicit example of this.. but it is supported in two alternatives. If you pass in a container, i.e. std::vector, as the binding value the multiple options will automatically collect into the vector:

std::vector<std::string> all_values;
cli |= lyra::opt(all_values, "value").name("-h");

The other is you can pass a lambda for the bound value that can collect as you wish. For example to collect only unique numbers:

std::unordered_set<int> unique_values;
cli |= lyra::opt([&](int v) { unique_values.insert(v); }, "value").name("-i").cardinality(0,0);

For that the latter you need to specify the cardinality as it default to one argument. The former defaults to multiple as it assumes that''s what you want when you give it a vector.

Thx so much for answer, it is exactly what I desire.
For me it was not so obvious.
