    advanced user output

    Hello

    I want to allow user to use advanced output feature with my application. In other words I want to have some simple scripting language inside c++ application so that user could call c++ functions from this simple scripting language.

    Is there anything similar available?
    I know for boost python, but to embed python interpreter in c++ makes binary for about 1mb bigger. I want to keep my exe as smallest as possible.

    User should be able to do something like this (for instance):

    Code:
    %c = random(2,5);
    %b = "some text";
    output = "this is" . %b . "... some random number: " . %c;
    And when my c++ aplication would parse this script, it would make the output string:
    "this is some text... some random number: 3"

    Thanks for help

    You might be able to cobble something together using a stringstream.

    The problem as stated is basically the problem of writing a compiler, which is pretty heavy stuff. So, my suggestion...

    If you want a lightweight scripting language... LUA might be the one for you.
    If you want to roll your own, the simplest way to go about it is to make a stack-based language, aka, one built around Reverse Polish Notation.

    I dont want to roll my own since that would take too much time to make something that will actually 'work'.
    I have also found out CLiPP - javascript interpreter, which uses boost libraries but I cant compile it.
