tiny-process-lib

A small platform independent library making it simple to create and stop new processes in C++, as well as writing to stdin and reading from stdout and stderr of a new process.

This library was created for, and is used by the C++ IDE project juCi++.

Features

• No external dependencies
• Simple to use
• Platform independent
  • Creating processes using executables is supported on all platforms
  • Creating processes using functions is only possible on Unix-like systems
• Read separately from stdout and stderr using anonymous functions
• Write to stdin
• Kill a running process (SIGTERM is supported on Unix-like systems)
• Correctly closes file descriptors/handles

Usage

See examples.cpp.

Get, compile and run

Unix-like systems

git clone http://gitlab.com/eidheim/tiny-process-library
cd tiny-process-library
mkdir build
cd build
cmake ..
make
./examples

Windows with MSYS2 (https://msys2.github.io/)

git clone http://gitlab.com/eidheim/tiny-process-library
cd tiny-process-library
mkdir build
cd build
cmake -G"MSYS Makefiles" ..
make
./examples

Coding style

Due to poor lambda support in clang-format, a custom clang-format is used with the following patch applied:
