Making a Portable VS-C++ (Based on VSCode)

The reason I do these next steps is just to get the LLVM directory. I uninstall it only because I don’t want too many items in the program list. If you’re not obsessive about that, you can skip steps 2-4 and just choose the first folder as the installation directory.

Install LLVM, install it anywhere for now
Copy the entire LLVM directory into the directory from step 1
Uninstall the LLVM from your system
Copy !start.vbs and start.bat from the appendix into the folder from step 1
Comment out the last line of start.bat i.e. add :: before the last line
!!Don’t close the window after this step!! In cmd (or PowerShell), run the script with .\start.bat, then type clang and gcc. If you get “xxx is not recognized as an internal or external command”, it means your start.bat configuration has a problem.
In the folder from step 1, create folders with the following names:

1
Users
2
Users\AppData
3
Users\AppData\Local
4
Users\AppData\Roaming
5
Users\AppData\Desktop
6

7
extensions

Install extensions

1
Chinese(简中语言包)
2
C/C++
3
vscode-clangd
4
Code Runner
5
Bracket Pair Colorizer 2
6
One Dark Pro(主题包,可选)

In the cmd (or PowerShell) from step 7, type .\code.exe to launch VSCode
Create a new directory in the file explorer (I just created a folder named !Code in the step 1 directory), open it in VSCode, then choose “Save Workspace As”

Note that you should put each language’s working directory in a separate folder, e.g. put C in the c folder and C++ in the c++ folder

Create a new folder named C++ inside !Code (adjust based on your own situation)
Create a .vscode folder in the C++ directory, then copy launch.json, tasks.json, settings.json, and compile_flags.txt from the appendix into it
Uncomment the line from step 6, close this VSCode, and run !start.vbs
Create a new file and type in some test code

1
#include <iostream>
2
using namespace std;
3
int main (){
4
    string a="";
5
    cout << "Input:" << endl;
6
    cin >> a;
7
    cout << a;
8
    return 0;
9
}

Click the arrow in the top right, and see if the console outputs Input:. Then type something and see if it’s echoed back unchanged
That’s it
