Calling Lua from C

[Patrick Rapin <toupie300@...>]

Hello,

I have two questions to ask to the entire community. Because for me,
there is a mystery.

 - Do you run Lua scripts from within a C or C++ application ?
 - If yes, what API are you using for it?

I thought that calling Lua from C[++] should be very common. Lua is
designed to be embedded, and is written in "clean C" to simplify
compilation in various environments.
The standard Lua API is powerful and complete, but not really handy.
You have to load the code (compile), push the arguments, make the
call, take the results back from the stack, and at most stages check
whether an error happened and retrieve error message. The sub-API
d'Arc does not simplify the task neither.

There are numerous Lua-C++ bindings that ease the process. None of
them seems popular however.
I feel frustrated, because I wrote two open-source libraries to simply
call Lua from C++ [1][2]. LuaClassBasedCall is particularly powerful
and easy to use.
It looks like nearly nobody uses it ! And I would like to understand
why, to decide if I should definitely stop any development on it.

Thank you,
Patrick Rapin
