## Setups
### VS Code Docker dev container (recommended setup)
The easiest Way is to use the VM Image (pw:rtsa) provided here:
1.) install docker and VS Code on your Distribution. Please keep in mind Dev containers are only supported by the native version of VS Code from Microsoft!
<https://tu-dortmund.sciebo.de/s/JbvtbtEADx92eEG/authenticate>
<https://docs.docker.com/get-docker/>
On this VM you can simply open VS Code from the desktop and start coding.
<https://code.visualstudio.com/>
Following are native setups and some other unrecommended Setups are at the end of this Readme.
For this setup you cannot use the OSS version of VS code or the version from Snap, as the remote development extensions will not work.
Also read the VS Code setup, which might be interesting independent from your chosen Setup.
2.) I recommend you install the following extensions in vs code
clangd,
Clang-Format,
CodeLLDB,
Docker and
Remote Development (Microsoft VS Code only!)
For a general C/C++ setup of VS Code (I consider good) see:
<https://ahemery.dev/2020/08/24/c-cpp-vscode/>
3.) The project comes with a pre configured dev container and should prompt you to use it after opening the project. With this you have a running setup. If not please continue reading the manual points.
3.manual.) Use the helper script to build and run a Container.
```bash
./helper.sh docker
```
This will build a docker image and run a Docker container with the current directory mounted.
The Docker container can later be started from the Docker VS Code extension.
4.manual) Attach VS Code to the container, in the Docker Tab, and start developing
### VS Code native setup
This is my personally preferred IDE setup for C/C++ and by no means needed to accomplish this exercise.

<https://ahemery.dev/2020/08/24/c-cpp-vscode/>
Most parts can be skipped, as they are already integrated in this Repo.
3.a.) Set the LLVM_DIR variable to your LLVM(14) installation.
```bash
export LLVM_DIR=<path/to/your/llvm/installation>
```
3.b.) You can auto config and build by hitting Ctr+Shift+B from the IDE or use the helper script.
4.) Pressing F5 will start a debug session, make sure to set halting points.
### Mac setup

## Debugging
@ -158,18 +160,11 @@ The best way to see what your function does is to use the [UnitTest.cpp](https:/
With "C++ TestMate" install you can simply run or debug the test from the side panel in VS Code (Flask Icon).
The "C++ TestMate" is not installed in the VM as I just added this feature now.
Please feel free to add more test cases to your liking in [UnitTest.cpp](https://git.cs.tu-dortmund.de/nils.hoelscher/RTSA-lab01-CacheAnalysis/src/branch/master/UnitTest/UnitTest.cpp).
## Configuring and building
The easiest way is to use the VS Code tasks in this project.
By using CTR+Shift+B you can config and then build the project.
