Ruby Debug for Nova
Connect Nova to the Ruby Debug gem enabling local and remote debugging.
The connection is made possible by the
rdbg command. This is why you can consider the extension as the Nova's vscode-rdbg counterpart.
Please be patient if you get into issues or limitations. We are still testing and improving the extension.
Right now not all the settings and features of
vscode-rdbgare supported. This is true especially for the remote debugger. The aim in the future is to bring it near to a one to one porting.
You need to install latest
debug gem and
rdbg command should be in
$ gem install debug
If you are using
ruby 3.1.0 or later the
debug gem comes bundled.
Local debugging (launch)
To start using the local debugger go to Nova's Project Settings and add a new "Ruby Debug" task from the provided template.
You can configure the debugger as you like in the Project Settings or run it as it is.
The default configuration will try to find the
rdbg command on your machine and run the current open file in Nova with the
If a breakpoint is found, the program execution should pause and the debugger console should appear.
Remote debugging (attach)
To start using the remote debugger go to Nova's Project Settings and add a new "Ruby Remote Debug" task from the provided template.
To use the remote debugger make sure you are running the
rdbg command with the
rdbg to listen for connections from the outside.
Right now the only connection method allowed is
It means that if at startup the debugger finds a single open
socketPath will use that, otherwise you have to specify which one to use.
Specifying the socketPath
Start by generating a
socketPath with the
rdbg --util=gen-sockpath command.
It should print something like:
Next configure the
rdbg command to use the generated socket by specifying
The last step is to tell the remote debugger to use the generated socket. You can do that in the Ruby Remote Debug task settings.
Ruby on Rails
Allow remote debugging by running
rails server under
$ rdbg --command --open --nonstop -- rails server
To use the new
bin/dev command edit your
web: rdbg --command --open --nonstop -- bin/rails server -p 3000 css: bin/rails tailwindcss:watch
You are welcome to contribute to the development!
All you have to do to get up and running is to fork, download and rename the folder from
After that you should be able to active the project as extension from the Nova's
