Detailed Description

Command for outputting a label statement.

A label is a name and a ":" chunk. The command pops the indentation before writing the label and restores it afterwards.

Labels are useful when you don't want to modify the current indentation level, e.g. when writing an access identifier for a class or a switch..case statement.

Example:

writer << Scope("class Vehicle", [](Writer& writer) {
    writer << Label("public") << NextLine();
    writer << "Vehicle(const std::string& maker);" << NextLine();
    writer << Label("private") << NextLine();
    writer << "std::string m_maker;" << NextLine();
}) << ";";

Output:

class Vehicle
{
public:
    Vehicle(const std::string& maker);
private:
    std::string m_maker;
};
