deviz is a VS Code extension that displays structured program output such as trees and graphs. It is intended to be used as a development tool for programs that work with this type of data.
deviz can show text output for any program, but to show structured output, your code has to use a library to communicate the output to deviz. Currently, only a Rust version of this library is available.
Install the VS Code extension.
A view will be added to the bottom of the Explorer, titled DEVIZ.
Click Start session within this view.
This view will list all of your input and output panes.
Click on the info pane to view the status of compilation/execution.
Open Workspace Settings and find the deviz settings.
You'll need to at least set the deviz Run Command setting, but you may also want to set
Compile Command.
Now when you modify the stdin pane, the stdout and stderr output for your program will appear
in the stdout/stderr panes.
