  tclbind::create_command(mod, "hello")
    .add_function(
        +[](boost::core::string_view name)
        {
          std::cout << "Hello " << name << "!" << std::endl;

load ./libgetstarted[info sharedlibextension]

hello [lindex $argv 1]

This C++17 library makes it easy to extend tcl with C++ or vice versa. It requires boost and TCL.

Read the docs here.

Why TCL?

Tcl is a unique combination of a full script language with a command language. You can execute other programs with tclsh, like this:

g++ hello_world.cpp

while at the same time load and execute arbitrary C or C++ code, e.g.:

load ./libbuildhelpers[info sharedlibextension]

g++ [list-sources]

where list-sources is a command defined in C++.

Since tcl can be embedded in C++ as well, it is also a great starting point for interactive console applications; and because of the syntax it can be used to create DSLs that do not look and feel like Tcl. redis and sqlite started out that way.
