VS-Code-for-CP

For competitive programming, I use Linux dual booted alongside Windows. My favorite IDE is VS Code and it's perfect for short codes in CP.

Install C++

sudo apt install g++

Instal VS Code

wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > packages.microsoft.gpg
sudo install -o root -g root -m 644 packages.microsoft.gpg /etc/apt/trusted.gpg.d/
sudo sh -c 'echo "deb [arch=amd64,arm64,armhf signed-by=/etc/apt/trusted.gpg.d/packages.microsoft.gpg] https://packages.microsoft.com/repos/code stable main" > /etc/apt/sources.list.d/vscode.list'
rm -f packages.microsoft.gpg

sudo apt install apt-transport-https
sudo apt update
sudo apt install code

Install C++ on VS CODE

Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.

ext install ms-vscode.cpptools-extension-pack

Install C/C++ Compile Run

Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.

Install Code Runner on VS CODE

Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.

ext install formulahendry.code-runner

Change Settings of Code Runner

Open Settings in vscode (ctrl + comma)
Search on Run Code Configuration
- on Clear Previous Output
- on Run In Terminal
- on Save All Files Before Run
Don't Close Settings because we will use it in the next step

Change Executor Map of Code Runner

Click on Edit in settings json at Executor Map By File Extension
at code-runner.executorMap edit in cpp label
choose one flag from these and put it in cpp label:
- this command for execute the file with cp flags and make the code terminate after one second
  - "cd $dir && g++ -std=c++2a -Wshadow -Wall -o -g -fsanitize=address -fsanitize=undefined -D_GLIBCXX_DEBUG $fileName -o $fileNameWithoutExt && timeout -k 0 1s $dir$fileNameWithoutExt"
- this command for execute the file with cp flags only
  - "cd $dir && g++ -std=c++2a -Wshadow -Wall -o -g -fsanitize=address -fsanitize=undefined -D_GLIBCXX_DEBUG $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt"
- this command for execute the file with cp flags but less debuger than the above one
  - "cd $dir && g++ -std=c++2a -Wshadow -Wall -o "%e" "%f" -O2 -Wno-unused-result $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt"
- this flag for Windows
  - "cd $dir && g++ $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt"
- this command for input and output from files with flags
  - "cd $dir && g++ -std=c++2a -Wshadow -Wall -o -g -fsanitize=address -fsanitize=undefined -D_GLIBCXX_DEBUG $fileName -o $fileNameWithoutExt && timeout -k 0 1s $dir$fileNameWithoutExt < input.txt > output.txt && rm $dir$fileNameWithoutExt"
- this command for input and output from files without flags
  - "cd $dir && g++ -std=c++2a $fileName -o $fileNameWithoutExt && $dir$fileNameWithoutExt < input.txt > output.txt && rm $dir$fileNameWithoutExt"

Use Files instead of terminal

We will use freopen and files txt to take input and output from use instead of terminal
First we should put this function in our code

void Fast_IO(){
    ios_base::sync_with_stdio(false), cin.tie(nullptr), cout.tie(nullptr);
    #ifndef ONLINE_JUDGE
        freopen("input.txt", "r", stdin), freopen("output.txt", "w", stdout); 
    #endif
}

Create text file and name it input.txt

Make Your Snippet

You can go to this site and make a snippet for you
After that you can copy the snippet and insert it in your vscode to call it in anytime

You can use my template for competitve programming with cpp from here

You can make two run commands with shortcut

Run with flags
Run without flags

- Go to keyboard Shortcuts or `Ctrl + k + s`
- search on code-runner
- make shortcut for `code-runner.run` for Run with flags
- make shortcut for `code-runner.runCustomCommand` for Run without flags
