I have a problem with the Delve debuger in visual studio code. Debugging begins but nothing happens. There is only information in the console:
time="2018-06-23T16:35:55+02:00" level=info msg="launching process with args: [C:\\Users\\LenovoPC\\go\\src\\test\\debug]" layer=debugger
Configuration of launch.json
"version": "0.2.0",
"configurations": [

"type": "go",
"request": "launch",
"mode": "debug",

"program": "${workspaceRoot}",

}
]
Based on how you install delve it will either end up in your PATH or
GOPATH/bin. If dlv binary is in your GOPATH/bin and this GOPATH is not
set as an environment variable, then make sure your PATH points to
this GOPATH/bin so that the Go extension can find the dlv binary.
Try to change the directory to filename to run the project from main.go of your project folder as
{

"host": "127.0.0.1",
"program": "${fileDirname}",
"env": {},
"args": [],
"showLog": true
}
]
}
Make sure $GOPATH is set (e.g. as ~/.go)
On terminal run the command
go env
to check for GOROOT and GOPATH variables to see if delve is synchronized with them

From Delve (May 2022):
Support for calling functions on ARM64 has landed! https://github.com/go-delve/delve/pull/2996
Requires Go & Delve built from source with the latest changes.
Call functions from a debug session on ARM64 CPUs, including the Apple M1!
Note: Support function call injection on arm64 with Go 1.19 (CL 395754, as noted in issue 2277), so you will need to wait for Q4 2022.
The following json works for me-
{

Which Go version?
Did you install delve with that version?
I use the vscode to debug my code, my code can run but it can't start debugging.
my launch.json:

"version": "0.2.0",
"configurations": [

]
}
Try deleting the .vscode file in your project directory, and then rerun it, with me it worked perfectly

There is a program written in D.
In the loop, a string is fed to the input, read and further execution of the algorithm takes place.
When running in normal mode, the program works without any problems.
When running in debug mode, I can't continue running the program because it hangs on the input process. I can't continue executing my code after pressing "Enter".
My launch.json:
"version": "0.2.0",
"configurations": [
{
"type": "gdb",
"request": "launch",
"name": "Launch Program",
"target": "./lesson_2/bin/lesson_2",
"cwd": "${workspaceRoot}",

}
]
I tried to connect an external terminal, but it didn't work out.
Did so:
"version": "0.2.0",
"configurations": [
{
"type": "gdb",
"request": "launch",
"name": "Launch Program",
"target": "./lesson_2/bin/lesson_2",
"cwd": "${workspaceRoot}",
"valuesFormatting": "parseText",
"console": "externalTerminal",
"debugOptions": [
"RedirectOutput"
]
}
]
And that's it:
"version": "0.2.0",
"configurations": [
{
"type": "gdb",
"request": "launch",
"name": "Launch Program",
"target": "./lesson_2/bin/lesson_2",
"cwd": "${workspaceRoot}",
"valuesFormatting": "parseText",
"externalConsole": true
}
]
I also tried adding this option, but nothing has changed:
"console": "integratedTerminal"
I use Native debug.
In general, I don't know what to do. I ask for help.
I seem to be missing something simple, but I can't figure out why I am unable to debug python using Visual Studio Code on Windows. I've tried setting up the debugger as shown by Microsoft, and this youtube video. I've done a clean install of Visual Studio Code (including the python extension) and Python 3.6. I have no other python versions installed. I keep getting the following errors in the Python Debugger:
cd "c:\Users\xxx\Documents\Python Scripts" ; env "PYTHONIOENCODING=UTF-8" "PYTHONUNBUFFERED=1" "C:\Users\xxx\AppData\Local\Programs\Python\Python36-32\python.exe" "C:\Users\xxx\.vscode\extensions\ms-python.python-2018.3.1\pythonFiles\PythonTools\visualstudio_py_launcher.py" "c:\Users\xxx\Documents\Python Scripts" 53746 34806ad9-833a-4524-8cd6-18ca4aa74f14 RedirectOutput,RedirectOutput "c:\Users\xxx\Documents\Python Scripts\.vscode\launch.json"
-bash: cd: c:\Users\xxx\Documents\Python Scripts: No such file or directory
env: ‘C:\\Users\\xxx\\AppData\\Local\\Programs\\Python\\Python36-32\\python.exe’: No such file or directory
It's complaining that it can't find the python.exe file, but it clearly can since VS code indicates that it's attached:

Pylinting works fine, and I have not custom user settings in Visual Studio Code that are related to python. I've tried setting the complete file path to python.exe in settings.json but it makes no difference.
Any help is greatly appreciated. Thanks in advance
I had the same problem but finally got out of it after several adjustment to my settings.
make sure all other settings are in place as you've mentioned especially pythonPath in settings.json and also get "python" installed from the "extension" toolbar in VS code.
Simply change your debug configuration from "Python: Scripts" (or any other configuration you've selected previously) to "Python: Terminal(external)" and you are good to go!
I know, is a pain and I'm experiencing the same.
Apparently python.exe is executing correctly. You will keep seeing that banner because "This is necessary to bootstrap the debugger."
At least this is what Microsoft says.
I'm trying to debug a revel app with visual studio but I can't get it to work.
I've seen this question how to debug revel framework(golang) application in visual studio code(vscode) but no answers yet...
I've tried with this config:
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch",
"type": "go",
"request": "launch",
"mode": "debug",
"remotePath": "",
"port": 2345,
"host": "127.0.0.1",
"program": "~/code/go/bin/revel",
"env": {},
"args": [],
"showLog": true
}
]
}
But I'm getting this error:
Failed to continue: "The program attribute must point to valid directory, .go file or executable."
I think it must be the rebel binary the one to be run here, but I don't know how to pass the app path, should it go in "args"?
Yes it's possible.
Suppose that the GOPATH is C:\Work\golang
Revel project name is myapp, thus the location of the project (workspace) will be C:\Work\golang\src\myapp.
Make some changes to the controllers etc...
Run the application with revel run myapp, then press CTRL+C to exit. This step is necessary to generate corresponding go files. The generated file, i.e. the main package will be available under ${workspaceRoot}/app/tmp/main.go
Configure launch.json as follows:
{
"version": "0.2.0",
"configurations": [
{
"name": "Launch",
"type": "go",
"request": "launch",
"mode": "debug",
"remotePath": "",
"port": 2345,
"host": "127.0.0.1",
"env": {},
"showLog": true,
"program": "${workspaceRoot}/app/tmp/",
"args": ["-importPath", "myapp", "-srcPath", "c:\\work\\golang\\src", "-runMode", "dev"]
}
]
}
The important parts are program and args parameters, while the other parameters are unmodified.
Set breakpoint and start the delve debugger...
EDIT:
Setting args parameter to ["-importPath", "myapp", "-srcPath", "${workspaceRoot}/..", "-runMode", "dev"] also work, and I think this should work in other platforms (Mac, Linux) too.
The error message is related to delve issue. See https://github.com/Microsoft/vscode-go/issues/986
