Thread: What Libraries and Headers would be good to use to wrap an bash script?

What Libraries and Headers would be good to use to wrap an bash script?

I am thinking to try learning C++ once more.

Decided that writing small useful programs would be a better path than trying to add features complex programs others have written.

There is an MSys2 (Cygwin like enviroment) wx-config script that would be better if it was wrapped by an C++ command line program.

wx-config is something like pkg-config for just the C++ wxWidgets library.

And, the command line options are not exactly like what the CodeLite IDE wants under the Windows OS.

Therefore, I need to add a few options and pass some options onto the MSys2 bash call of the wx-config script.

I wish to use libraries/classes that are standard in C++ or Boost.

I see two types of libraries/classes I need suggests of which ones to research.
1. Ones to handle command line options
I have found

Code:

boost::program_options

by using web search.
2. Ones to call external command line programs and record the response from the program.
I have failed to find any class that does something like C's system or exec functions.

How about Chapter 30. Boost.Process - 1.76.0

Quote:
Boost.Process is a library to manage system processes. It can be used to:
* create child processes
* setup streams for child processes
* communicate with child processes through streams (synchronously or asynchronously)
* wait for processes to exit (synchronously or asynchronously)
* terminate processes

Here's a simple example of how to start a program with Boost.Process:

Code:

#include <boost/process.hpp>
#include <string>
#include <iostream>
 
using namespace boost::process;
 
int main()
{
    ipstream pipe_stream;
    child c("gcc --version", std_out > pipe_stream);
 
    std::string line;
 
    while (pipe_stream && std::getline(pipe_stream, line) && !line.empty())
        std::cerr << line << std::endl;
 
    c.wait();
}

john.c: Thank you. I figured there had to be a class.
