I want the output from my program to be printed on an empty terminal. ie, instead of,
PS C:\Stuff\More Stuff> & 'c:\Users\user\.vscode\extensions\ms-vscode.cpptools-1.4.1\debugAdapters\bin\WindowsDebugLauncher.exe' '--stdin=Microsoft-MIEngine-In-w1d2d2zg.skd' '--stdout=Microsoft-MIEngine-Out-2q3w4dx4.xne' '--stderr=Microsoft-MIEngine-Error-sr0qr1un.pod' '--pid=Microsoft-MIEngine-Pid-zddzumbv.aaf' '--dbgExe=C:\Program Files\CodeBlocks\TDM-GCC-64\bin\gdb.exe' '--interpreter=mi'

So, is there a way to output the program into an empty terminal?
Edit: I found a similar question here, but the solution posted doesn't work for me. It says, "Property console is not allowed". I am using the f5 debugger to run my C++ programs. I found some other similar questions, but they don't have an answer.
For now, the best working solution I could find is running the following command at the start of the program.
int main()
{
cout << "\033[2J\033[1;1H";
/*rest of the code here*/
}
This clears the terminal before execution of the actual program. This will also clear any outputs from previous runs. I'd prefer to have my previous outputs.

I'm new to VS Code. I got debugging with lldb working--for one day it worked great.
Then it began to malfunction, displaying the arrow several source statements away from the actual execution. I've tried several config changes using online guidance to no avail. I thought that maybe the debug database was messed up so I wanted to try to get it to regenerate, so moved the outDebug file aside. That did not cause it to be rebuilt.
I'm running this launch.json configuration:
{
"name": "(lldb) Launch",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}/rmv_ms",
"args": [],
"stopAtEntry": true,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "lldb",
"miDebuggerPath": "/usr/bin/lldb",
"preLaunchTask": "clang build active file"
},
and this in tasks.json:
"tasks": [
{
"label": "clang build active file",
"type": "shell",
"command": "/usr/bin/clang",
"args": [
"-std=c17",
"-stdlib=libc++",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${workspaceFolder}"
},
"group": { "kind":"build", "isDefault":true },
"presentation": {
// Reveal the output only if unrecognized errors occur.
"reveal": "silent"
},`enter code here`
// Use the standard MS compiler pattern to detect errors, warnings and infos
"problemMatcher": "$gcc"
}
]
The latest behavior is that when I try to start debug session it displays a menu asking me what to attach to (whatever that means) but I don't even see my program listed.
I'm trying to use the gdb debugger on macOS BigSur (11.4) without any success. I always get the same error : Unable to start debugging. GDB exited unexpectedly with exit code 134 (0x86), even though I tried to create a certificate and sign it (like this : https://www.ics.uci.edu/~pattis/common/handouts/macmingweclipse/allexperimental/mac-gdb-install.html), and I tried to enable debugging with the command csrutil enable --without debug (like this : https://gist.github.com/gravitylow/fb595186ce6068537a6e9da6d8b5b96d).
I'm using that launch.json file :
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.

I'm using VsCode : Version: 1.58.0-insider (Universal).
If you have another idea.
Thank you!
How does one add user input when debugging on VScode?
I have tried the following
Edited my launch.json to set externalConsole : true
Tried giving input as a command line argument as mentioned here
Irrespective of following step by step the above methods, something was off.
I kept getting a window where I couldn't do anything. The step up / down / in buttons went inactive.

The resolve is given in a gist here
The issue is when VSCode launches the debug adapter, then the debug adapter launches lldb-mi, then lldb-mi launches Terminal. There is a prompt that should appear, but somehow the DebugAdapter is not forwarding this permissions request.
The work around is to have VS Code launch the terminal once. You can do this by adding and running this tasks in your tasks.json:
{
"label": "Open Terminal",
"type": "shell",
"command": "osascript -e 'tell application \"Terminal\"\ndo script \"echo hello\"\nend tell'",
"problemMatcher": []
}
You can run this specific task using Command + Shift + p. Type Tasks and look for Tasks: Run Tasks then select Open Terminal.
I have written a small blog post about the same, detailing each and every step with images which can be found here.
I've set up a launch.json file such that a C++ program uses an external console (so that it can receive user inputs), but when launching, VSCode simply opens a terminal window without running the program in it. If "externalConsole": true, is set to false, the program runs and can be debugged fine, just can't take inputs.
Note: No task.json file is used, CMake is used to create the executable binary.

Is it possible that VSCode doesn't have 'permission' to run an external terminal? Using on MacOS.
I have the same issue. This may not be the working answer, but hopefully it will get us farther down the correct path.
I did some digging and found the following:
VS Code Documentation mentioned that it opens an external console via lldb-mi.
A search for lldb-mi led to this post on the Apple Developer forums.
...which leads to an open source Github Repo with a build of lldb-mi
I need to read through the documentation for that build first, and then I'll give it a shot. I'll post results if it solves the issue.
I've tried to use standard (recomended ways of debugging from vscode documentation) and ran into the same issues with external terminal.
I'm also using mac and switching to CodeLLDB plugin to use LLDB for debugging helped
https://marketplace.visualstudio.com/items?itemName=vadimcn.vscode-lldb
just follow documentation: https://github.com/vadimcn/vscode-lldb/blob/v1.8.1/MANUAL.md
But as a hint here is my working setup:
(I couldn't though make it work on windows, but I'm running windows via Parallel II, so maybe natively this plugin will work too)
tasks.json

just make sure you have all tools available, check by running in cli:
/usr/bin/clang --version
# and
lldb --version
good luck
I have a C file that I'm trying to debug but fail.
I'm using vscode on windows 10.
The file is quite large so I don't want to copy it here.
This is how my launch.json file looks in the .vscode folder in the folder that I'm working in:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/? linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "gcc.exe build and debug active file",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}\\${fileBasenameNoExtension}.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"miDebuggerPath": "C:\\MinGW\\bin\\gdb.exe",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "gcc.exe build active file"
}
]
}
This is how my tasks.json looks like in the same .vscode folder:
{
"tasks": [
{
"type": "shell",
"label": "gcc.exe build active file",
"command": "C:\\MinGW\\bin\\gcc.exe",
"args": [
"-g",
"${file}",
"-o",
"${fileDirname}\\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "C:\\MinGW\\bin"
}
}
],
"version": "2.0.0"
}
when I press the "start debugging" button the screen freezes and the program stalls and then vscode crashes
I managed to find a solution, I deleted the old files, clicked debug, it wanted me to create a new configuration, chose gcc launch and then there was an option 'gcc.exe build and debug active file' , clicked it, and now everything works.
I've updated the content of the files above to how they look right now if anyone has the same issue in the future.
