I have developed this testing framework for fast offline development of code puzzles to be solved in C++. This is compatible with all different coding puzzle platforms which work with string input and string output, such as https://www.codewars.com, https://www.codingame.com, https://onlinejudge.org and many more.

There is an example / template in src/codewars/easy_puzzles/pXXX_YYY.cpp. All the TODO's there should indicate the places where you should do changes if you copy this template file for your own puzzles.

Feel free to fork, create issues or pull-requests if you have feedbacks or ideas to improve this testing framework.

If you use CLion by JetBrains, then you can simply do the following to get up and running:

• Simply choose the sub-application in src/main.cpp and run or debug.
• If you want to create a new problem, just select:
  • New > C/C++ Source File
  • Name the file
  • Make sure that the following two options are ticked:
    • Create an associated header
    • Add to targets (add's the )
  • With that, the associated header file is created and the targets are correctly added to CMakeLists.txt
• Make sure, that the entry-method is exposed in its header file
• Include this entry-method in src/main.cpp with #include... and call the method

The following commands are for macOS:

• 'cmd' + 'o': search and navigate to another class
• 'cmd' + 'b': Navigate to a definition
• 'alt' + '⇧': Extend selection

See overview, tips and video on https://www.jetbrains.com/clion/features/run-and-debug.html

• Place cursor at something (e.g., a function), then 'ctrl' + 't' (on macOS) -> brings up the "Refactor This" menu, e.g. for:
  • Renaming (in all usages)
  • for signature changes (incl. default-values) for a function (and changing order of arguments)
    • 'alt' 'F7': shows all the usages of a function
  • Extract variables/parameters/typedefs/methods/superclass
  • Pull/push members up/down (to base-class/super-class)
  • Move stuff to other classes / files (including their header-definitions and includes and everything!)
  • Copy stuff
  • Safe delete
• Inside a class or struct, press 'cmd' + 'n' for the "Generate Menu" (for constructors, getters/setters, equality and relational operators and so on)
• Use "Live Templates with 'cmd' + 'j'
• Surround blocks of code with "Surround With": 'cmd' + 'alt' + 't'
• See more Tips at https://www.jetbrains.com/clion/features/code-generation-and-refactorings.html

Occasionally when updating macOS, suddenly, nothing was compiling anymore. Even a few of the imports were marked red (but by far not all) such as #include <stdio.h>. When making changes to CMakeList.txt and hitting the button "Reload changes", I noticed that it complained:

Ignoring CMAKE_OSX_SYSROOT value:
/Application/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.15.sdk

because the directory does not exist.

-> It did not show anymore my current macOS version

The solution was to remove the folder "cmake-build-debug", then make a small change in "CMakeList.txt" (like excluding one file saving, and click "Reload changes"). That rebuilt the folder "cmake-build-debug" and all problems were gone.
