The task is defined inside the .vscode/tasks.json file. Create and run an "attach" debug configuration that attaches to the debug target. Review all automatically generated values and make sure that they make sense for your project and debugging environment. Select an extension tile above to read the description and reviews to decide which extension is best for you. The best way to explain the difference between launch and attach is to think of a launch configuration as a recipe for how to start your app in debug mode before VS Code attaches to it, while an attach configuration is a recipe for how to connect VS Code's debugger to an app or process that's already running. You can initiate condition editing from the context menu, or the new inline Edit Condition action. I’ve not seen example syntax of a “named” task, but the schema documentation reveals a property called taskName. It can either be the default floating, docked to the Run view or hidden. You can open additional Watch windows by selecting windows 2, 3, or 4.

There is, however, one exception: the Node.js debugger included in VS Code supports remote debugging. However, for most debugging scenarios, creating a launch configuration file is beneficial because it allows you to configure and save debugging setup details. Also, note that the value under label corresponds to the value under preLaunchTask as we are launching QEMU before GDB starts. You can type an expression into the Watch section of the Debug panel and it will be evaluated each time a breakpoint is hit. Log messages are plain text but can include expressions to be evaluated within curly braces ('{}'). Launching your Extension Launch.json supports defining values (for example, arguments to be passed to the program) that depend on the operating system where the debugger is running. Inline breakpoints can also have conditions. Here is an example of a simple Node.js Express application: This application first installs a "Hello World" handler for the "/" URL and then starts to listen for HTTP connections on port 3000. As soon as a second session is up and running, the VS Code UI switches to multi-target mode: An alternative way to start multiple debug sessions is by using a compound launch configuration. If the debugger extension you are using can run the debug target in VS Code's Integrated Terminal (or an external terminal), you can try to pass the shell redirect syntax (for example "<" or ">") as arguments.

An inline breakpoint can be set using ⇧F9 (Windows, Linux Shift+F9) or through the context menu during a debug session. Tip: The Run action is always available, but not all debugger extensions support 'Run'. You can use the yo code Yeoman generator to do this and we cover the details in the extension generatortopic. You can add a condition and/or hit count when creating a source breakpoint (with the Add Conditional Breakpoint action) or when modifying an existing one (with the Edit Condition action). Contribute to golang/vscode-go development by creating an account on GitHub. Variable values can be modified with the Set Value action from the variable's context menu.

The individual sessions now show up as top-level elements in the, Debug actions (for example, all actions in the debug toolbar) are performed on the active session. As soon as a debugging session starts, the DEBUG CONSOLE panel is displayed and shows debugging output, and the Status Bar changes color (orange for default color themes): In addition, the debug status appears in the Status Bar showing the active debug configuration. Variable values and expression evaluation are relative to the selected stack frame in the CALL STACK section.

Optionally a preLaunchTask can be specified that is run before the individual debug sessions are started. Define that preLaunchTask as a background task with a (non-background) dependsOn task to execute before it. Below are several popular extensions which include debugging support: Tip: The extensions shown above are dynamically queried. Please note that the type property cannot be placed inside a platform-specific section, because type indirectly determines the platform in remote debugging scenarios, and that would result in a cyclic dependency. Breakpoints can be toggled by clicking on the editor margin or using F9 on the current line. My custom “named” task looked something like this: I then tried changing the property name from taskName to just name, based on this link.

On the other hand, if you come from a server or desktop background, it's quite normal to have your editor launch your process for you, and your editor automatically attaches its debugger to the newly launched process.
