Hello I'm working with pipenv which have a differetn path for every developer, but I want to have the same launch setting for all. The problem is that the program is not the python is a custom executable with is under the virtual environment bin folder.
Here is my current launch.json
{
"name": "Python: TEST",
"type": "python",
"request": "launch",
"stopOnEntry": false,
"console": "integratedTerminal",
"program": "${env:HOME}/.local/share/virtualenvs/venv-PbRe8Lzd/bin/<program>",
"args": [
...
],
"cwd": "${workspaceRoot}",
}
And for me works OK becaouse my is under "venv-PbRe8Lzd/bin/" but for the other developers that have different venv folder no. Any Idea on how to do this generic for all?
I think better not to sync .vscode folder at all. But anyway it's possible to put interpreter path into another file ".vscode/settings.json".
Delete "program" from launch.json.
Install the Python extension for Visual Studio Code https://github.com/Microsoft/vscode-python (probably it's already installed)
Press Ctrl+Shift+P
Search "Python: Select Interpreter"
Select pipenv interpreter path
or
Create/modify file ".vscode/settings.json"
{
"python.pythonPath": "${env:HOME}/.local/share/virtualenvs/venv-PbRe8Lzd/bin/python"
}

I am working in a monorepo that has jest.config.js and package.json files in subfolders that represent independent projects in this monorepo, example:
items/thing/
items/other/
items/something/
In VSCode, if I have a test file in focus, I can then use this config item to run that test file in the items/thing/ folder.
"name": "Jest (this file)",
"type": "node",
"request": "launch",
"cwd": "${workspaceFolder}/items/thing",
"runtimeArgs": [
"--inspect-brk",
"${workspaceFolder}/node_modules/.bin/jest",
"${relativeFile}"
],
However, to do the same in the items/other/ folder I need to change the cwd property to that value.
Is there a way to "tie" the cwd to the closest parent that has the config/package files so I don't have to adjust the launch.json settings each time? (Or another way to solve this?)
I am a complete beginner with C and to VSCode. I am trying to configure the task and launch jsons but have no idea where to begin. I have tried googling the answers but I keep getting the same errors. I want to be able to step through the code line by line so I can see what it is doing.
I haven't changed the tasks.json from the original that VSCode sets. The launch.json I have changed by putting in the debugger path and the path of the executable. I have included the task.json, launch.json and the error that keeps popping up. Any help is appreciated.

I've recently had the same issues. Here is the procedure that I follow, that seem to work:
Download and install msys2 (1)
Download MSYS2 from https://www.msys2.org/
Install folder is typically C:\msys64
Go to C:\msys64 and open mingw64.ini
Change ‘#MSYS2_PATH_TYPE=inherit’ to ‘MSYS2_PATH_TYPE=inherit’ i.e. enable PATH variable.
Add PATH environment variables (2)
Type “environment” in Windows search field, and select “Edit environment variables …”
Add path to gcc.exe and g++.exe:
— Add: “C:\msys64\mingw64\bin” to PATH variable.
Add path to VS Code to PATH variable as well:
— This is usually the folder:
C:\Users\<username>\AppData\Local\Programs\Microsoft VS Code\
Run “msys2 mingw64” and test access to compilers and debugger (3)
In Windows Search field, type “msys2” and select “msys2 mingw64” and run the following:
To install gcc, the Gnu C compiler: pacman -S mingw-w64-ucrt-x86_64-gcc
To install gdb, the Gnu GDB debugger:
pacman -S --needed base-devel mingw-w64-x86_64-toolchain
To test that you can run compilers and debugger, run:
gcc --version
g++ --version
gdb --version
Start development in VSC (4)
Open “msys mingw64” terminal and run:
cd <common projects folder>
mkdir <projname>
cd <projname>
Above changes current directory to a projects folder. I use C:\Users<username>\src\projects, i.e. this is my but you may want to use something else.
In the folder you can make a subfolder per C coding project you want to run. This is what “mkdir ” does.
You will need a little Unix Bash shell command skills here, here is an ultrashort summary:
cd – change directory to
mkdir – makes a new directory called
in the current folder.
cd .. – change directory one up.
_ cd ~ – changes directory to your home folder, I have C:\Users<username> where is my … username.
pwd – shows current directory.
Now, if you did above you are currently in the specific projects folder (you can verify this with pwd), and you should start VSC from there by typing:
code .
And accept Workspace trust.
Create a C source file (5)
Open folder view, click on + icon, and select ‘new file’, type “hello.c”, go into the file and add the contents:
include
int main() {
printf("Hello World\n");
return 0;
}
Configure VSC for building – tasks.json (6)
Press “ctrl+shift+B” to build target (or menu: -> Terminal -> Run Build Task… or press green play icon)
Select “C/C++: gcc.exe build and debug active file”
Now it tries to build, using an autogenerated tasks.json file, located in project-folder, in subfolder .vscode:
.vscode/tasks.json
An example of a tasks.json file is shown below:
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: gcc.exe build active file",
"command": "C:\apps\msys64\mingw64\bin\gcc.exe",
"args": [
"-fdiagnostics-color=always",
"-Wall",
"-g",
"${file}",
"-o",
"${fileDirname}\${fileBasenameNoExtension}.exe"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": {
"kind": "build",
"isDefault": true
},
"detail": "Task generated by Debugger."
}
],
"version": "2.0.0"
}
The important section is:
"command": "C:\msys64\mingw64\bin\gcc.exe",
"args": [
"-fdiagnostics-color=always",
"-Wall",
"-g",
"${workspaceFolder}/*.c", OR TODO "${file}"
"-o",
"${fileDirname}\${fileBasenameNoExtension}.exe"
],
“command” is the Gnu C compiler, gcc.exe and the full path to it.
“args” are arguments for the compiler:
-Wall means warn about everyting.
-g means compiler must prepare for debugging.
“${file}” is current file.
-o is output file which is specified in the next line with .exe extension.
Sometimes we have to build multi-file projects and it will break the default build-functionality in tasks.json in VSC. In some cases this can be solved by changing:
${file},
to
"${workspaceFolder}/*.c",
Configure VSC for Debugging – launch.json (7)
Go to source file hello.c, and set a break point,
Click left to the line numbers to set red circle.
Select play/bug icon
Select “Debug C/C++ File”
Choose “C/C++ gcc build and debug active file” from list of automatically detected compilers.
This will autogenerate a file, launch.json in the projects folder, in subfolder .vscode:
.vscode/launch.json
An example of a launch.json file is shown below:
{
"configurations": [
{
"name": "C/C++: gcc.exe build and debug active file",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}\${fileBasenameNoExtension}.exe",
"args": [],
"stopAtEntry": false,
"cwd": "${fileDirname}",
"environment": [],
"externalConsole": false,
"MIMode": "gdb",
"miDebuggerPath": "C:\\msys64\\mingw64\\bin\\gdb.exe",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
},
]
}
],
"preLaunchTask": "C/C++: gcc.exe build active file"
}
The most important parts are:
"program": "${fileDirname}\${fileBasenameNoExtension}.exe",
and
"miDebuggerPath": "C:\\msys64\\mingw64\\bin\\gdb.exe",
The “program” is the program generated when building the project. I.e. the output from running the task as specified in Tasks.json.
The miDebuggerPath is the path to gdb, the GNU gdb debugger.
If these does not match with your Tasks.json settings and your installation chances are slim to make it work.
Test it by pressing the Play/Bug icon button and notice if there are errors. If not you should be able to step through the code and watch variables etc.
Configure VSC for intellisense (8)
Install extension: “C/C++ extension for VS Code” by Microsoft.
Now this extension will assist when you type code. By example you can type for to get the basics of a for-loop. Similar for if, while etc. Cool!
Save work when creating new projects (9)
Instead of having to create the tasks.json and launch.json files for each project, I copy them to a templates folder, say:
C:\Users\username\src\templates\.vscode\
Copy the newly created tasks.json and launch.json files to the .vscode subfolder.
Now, say you want to create a new project, e.g. hello2, and you create a folder for it:
C:\Users\<username>\src\projects\hello2\
Go to the templates folder by
cd C:\Users<username>\src\templates
and copy the .json files to the new project by:
cp -Rp .vscode/ ../hello2/
And now the new project has the .json files.
Optional (10)
Later you may want to update msys2. To do this, open “msys2 mingw64” and type
pacman -Suy
Done (11)
Finally done … Not the easiest thing to get going, but I still think it is worth it.
I want to set up VScode (OS: Windows 10) to create and then compile programs written in Fortran 90/95. I can do this by typing in the terminal : gfortran -o Example_exe Example.f90 and then ./Example_exe. I don't want to have to write these lines every time, so I tried to set up my tasks.json file to automate a build routine using gfortran as compiler.
I found this tutorial : https://titanwolf.org/Network/Articles/Article?AID=360e0bde-0507-4de4-960c-2eae8fa8c782#gsc.tab=0 but the tasks.json file given is unclear.
Can I have a tasks.json file setup to automate my build routine please ?
I have installed the following extensions : Modern Fortran, Fortran IntelliSense, Code Runner, Fortran Breakpoint Support
Yes you can. Assuming that you want to execute in debug mode, you should create a tasks.json and a launcher.json and place them in .vscode/ at the root of your workspace.
Assuming the following file structure and a debugging mode with GDB for the execution:
root/
.vscode/
code/
Example_exe
This is what your tasks.json should look like:
{
"version": "2.0.0",
"tasks": [
{
"label": "compile",
"type": "shell",
"command": "gfortran -o Example_exe Example.f90 -g",
"options": {
"cwd": "code/"
}
}
]
}
And then, the launch.json, which will identify tasks.json as a "preLaunchTask".
{
"version": "0.2.0",
"configurations":[
{
"name": "Run my example",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceFolder}\\code\\example_exe.exe",
"args": ["],
"stopAtEntry": false,
"cwd": "${workspaceFolder}\\code",
"miDebuggerPath": "gdb.exe",
"preLaunchTask": "compile",
}
]
}
Launch the debugger by pressing F5 (or in the Run menu).
If you don't want to run in debug mode, have a look at this issue.

How to build and run C++ code in Visual Studio Code?
awesome tutorial (for ubuntu, working for me with VSCode-gfortran-Win10)
https://www.youtube.com/watch?v=Rj-kYb9nZ3g&ab_channel=LukasLamm.
I am a new user to vscode. I viewed Lukas Lamm's video of vscode Fortran, but I am still having problems:
can't build code
can't launch code for debug
I have a makefile which requires some environment variable definitions for, say, the compiler type, $COMPILER. I have included the makefile extension but when I do a 'make all' there, the environment variables remain undefined. I have no problem doing a 'make all' in the vscode terminal window. How do I configure the Makefile extension to parse these environment variables?
I did write a launch.json file to run my code - I think exactly the way Luke Lamm indicated in his video. My code requires an input file:
heatx.exe < heatx.inp
but it never finds it - it just hangs at the read statement (It finds heatx.exe fine). Below is my launch.json script:
{
"version": "0.2.0",
"configurations": [
{
"name": "Run GDB",
"type": "cppdbg",
"request": "launch",
"program": "${workspaceRoot}/heatx.exe",
"args": [
"<",
"${workspaceFolder}/heatx.inp"
],
"stopAtEntry": false,
"cwd": "${workspaceRoot}",
"externalConsole": false,
"MIMode": "lldb",
"preLaunchTask": "make"
}
]
}
I checked other vscode questions about input files and this was exactly the solution they suggested.
I don't think this has anything to do with makefiles so you should probably remove the makefile tag.
I'm no expert at vscode, but I don't think this can work:
"program": "${workspaceRoot}/heatx.exe",
"args": [
"<",
"${workspaceFolder}/heatx.inp"
],
IO redirection (handling of <) is a feature of the shell. Here you're not invoking a shell, you're invoking heatx.exe, so there's nothing to handle the redirection. This basically runs your program heatx.exe with two arguments: a literal < and the file .../heatx.inp. But your program is reading from stdin, and nothing is there.
You either need to rework your program so it takes a filename and opens that file and reads from it, so you can run heatx.exe heatx.inp, then you can use:
"program": "${workspaceRoot}/heatx.exe",
"args": [
"${workspaceFolder}/heatx.inp"
],
Or you have to run a shell and tell it to run your program in a shell script, like this:
"program": "/bin/sh",
"args": [
"-c",
"${workspaceRoot}/heatx.exe < ${workspaceFolder}/heatx.inp"
],
Note! This will work on any POSIX system like Linux or MacOS. You don't say what system you're working on but this likely won't work on Windows unless you have various things installed and set up, and you might need to use a different path for a shell. Or I guess you could try to write it with cmd.exe but all this Windows stuff is beyond me.
Since Visual Studio Code was created using Electron, I'm guessing that launch.json might be configured to properly launch an app using Electron. But I've not figured out how to do it yet.
Also since Electron is based on io.js, itself based on Node.js, I'm thinking maybe... it can be done, but haven't found the magic yet.
Tried something along these lines... snippet from launch.json:
"configurations": [
{
// Name of configuration; appears in the launch configuration drop down menu.
"name": "Launch Electron",
// Type of configuration. Possible values: "node", "mono".
"type": "node",
// Workspace relative or absolute path to the program.
"program": "Y:\\dev\\electron\\electron.exe",
// Automatically stop program after launch.
"stopOnEntry": false,
// Command line arguments passed to the program.
"args": ["CrawlSpace_Electron\\"],
// Workspace relative or absolute path to the working directory of the program being debugged. Default is the current workspace.
"cwd": ".",
// Workspace relative or absolute path to the runtime executable to be used. Default is the runtime executable on the PATH.
"runtimeExecutable": null,
// Environment variables passed to the program.
"env": { }
},
It does start Electron, but fails (window vanishes too fast to see exactly why).
Any thoughts?
If you specify electron.exe as the runtimeExecutable (as previously suggested) you can pass the main.js file as the program and it will work. Electron allows you to specify the directory OR the main.js file since that is pretty much what the package.json points to. Using the configuration below in my launch.json file, pressing F5 both launched Electron with my app and connected the debugger to the main process (eventually)...
{
"name": "Launch Electron",
"type": "node",
"program": "${workspaceRoot}/app/main.js", // ensure this is path to main.js file
"stopOnEntry": false,
"args": [],
"cwd": "${workspaceRoot}",
// as you have noted, this is also important:
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron.cmd"
},
My main.js file is in the app folder I normally would pass to Electron.
Yes, it could. Not only could VSCode launch Electron, it could also debug it.
Using node you can debug Electron's Main process, but with Debugger for Chrome you can also debug Electron's Renderer process. I wrote a blog post on this topic: http://code.matsu.io/1.
The current highest upvoted answer is a bit outdated.
You should use electron instead of electron-prebuilt. See http://electron.atom.io/blog/2016/08/16/npm-install-electron
You should use node_modules/.bin/electron to launch electron
On Windows it's electron.cmd, not electron.exe.
Here are two pre-configured projects: https://github.com/octref/vscode-electron-debug.
One configured to run electron/electron-quick-start
One modified from electron/electron-quick-start to use ES6 & Babel & Webpack.
Here is the launch.json for the first project. To run the target "Debug Renderer Process", you need to install Debugger for Chrome. But "Debug Main Process" works fine on vanilla VSCode.
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Main Process",
"type": "node",
"request": "launch",
"cwd": "${workspaceRoot}",
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron",
// Use the following for Windows
// "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron.cmd",
"program": "${workspaceRoot}/main.js"
},
{
"name": "Debug Renderer Process",
"type": "chrome",
"request": "launch",
"runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron",
// Use the following for Windows
// "runtimeExecutable": "${workspaceRoot}/node_modules/.bin/electron.cmd",
"runtimeArgs": [
"${workspaceRoot}/main.js",
"--remote-debugging-port=9222"
],
"webRoot": "${workspaceRoot}"
}
]
}
In theory the following should work:
Specify the electron.exe as the "runtimeExecutable" (since it replaces the node runtime). The electron program ("CrawlSpace_Electron\") becomes the "program". VSCode automatically passes a "--debug-brk" or "--debug" to electron.exe.
In practice VSCode does not yet support this setup because the preview version of VSCode tries to verify that the "program" attribute is a file that exists on disk. But for electron the "program" must be a directory.
I have created a bug on our side and will make sure it’s fixed with the next release.
I know this is just 1 link but it's the answer everyone needs...
https://code.visualstudio.com/docs/editor/debugging#_launchjson-attributes
Here are the attributes documented for launch.json. Unsure if the list is currently complete, but it should at least help...
On OSX the path to electron is
"runtimeExecutable": "${workspaceRoot}/node_modules/electron-prebuilt/dist/Electron.app/Contents/MacOS/Electron",
