How do I automatically clear VS Code terminal when starting a build?

Question

I press Ctrl+Shift+B to start a build in Visual Studio Code (it\'s configured to just run GNU Make), and the build tool out

Answer 1

Add this user setting to clear the OUTPUT tab on clicking run (▶)

"code-runner.clearPreviousOutput": true,

This is not the same as clearing the terminal but it might be what someone wants.

[Edit] This requires the Runner extension, which I'd recommend for testing/running scripts directly within VS Code.

Answer 2

You can change from settings menu (at least from version 1.30.2 and above)...

On Mac, just hit Code > Preferences > Settings.

Then just search for "clear" and check Clear Previous Output.

Answer 3

If you control the build task yourself, it's easy to prepend a clear command:

"tasks": [
    {
        "label": "build",
        "type": "shell",
        "command": "clear && make",
....

November 2018 Update

As of this commit (and a few subsequent follow-ups), you can now add a clear presentation option to your task to have it clear the terminal before each task run.

Working example (on fresh clone+build):

{
    // See https://go.microsoft.com/fwlink/?LinkId=733558
    // for the documentation about the tasks.json format
    "version": "2.0.0",
    "tasks": [
        {
            "label": "[gcc] Build",
            "type": "shell",
            "command": "g++",
            "args": [
                "source.h",
                "-Wall",
                "-o",
                "a.out"
            ],
            "presentation": {
                "clear": true                        // <-- this line
            }
        }
    ]
}

(Note: the linked commit diff has the key being named clearBeforeExecuting but it's apparently since been changed to just clear).

Prior to this, I created a clear_g++ script on my path with just:

#!/bin/bash
clear
exec g++ $*

And changed my command from g++ to clear_g++.

Since I liked the idea of this approach but it didn't end up working out.

I tried to find a solution but can't. Simple hack I tried is to open new build in new tab. Add this presentation key to your task in tasks.json

 "presentation": {
                "echo": true,
                "reveal": "never",
                "focus": false,
                "panel": "new"
            }

panel:new will open in new terminal.
