String interpolation for clang++ - Yet another post-pre processor

Install globally with npm:

npm i -g derp-cpp

General help

Usage:
    derp -
    derp -h | --help 

Description:
    Expands C++ interpolated strings from a program read from stdin. Produces the manipulated program on stdout.

This is just a post processor to be run after clang++ preprocessor (-E option).

Example

Assume the following c++ file (example.cxx):

#include <string>
#include <iostream>
 
auto s = "variable string";
 
int main()
{
    std::cout << "This is an interpolation of '#{s}' that goes to stdout\n";
}
 

Compile it with:

> clang++ --std=c++11 -E example.cxx | derp > example.c++ &&  clang++ -o example --std=c++11 example.c++

And then run it:

> ./example 
This is an interpolation of 'variable string' that goes to stdout
