Automatically removing robots.txt provided by Drupal core

Maybe we can add another command to make sure that the robotstxt module is installed on all instance sites, like a "drush @sites pm-enable robotstxt -y" or with the drupal console ...

I changed the command to "rm -f web/robots.txt" to do not have error message if the robots.txt is already deleted.

In order to automatically remove robots.txt file and ensure that it stays removed, the following entry can be made in composer.json:

"extra": {
        "drupal-scaffold": {
            "file-mapping": {
                "[web-root]/robots.txt": {
                    "mode": "skip"
                }
            }
        },
-----------other lines of codes--------------- 
    }

This will ensure that robots.txt will be skipped when composer install or composer update is run.

That's the most elegant way, thank you!

As per #9

This didn't work for me.

            "file-mapping": {
                "public_html/robots.txt": {
                    "mode": "skip"
                }
            }

The file still got scaffolded.

This worked.
,

    "scripts": {
      "post-install-cmd": [
        "rm public_html/robots.txt"
      ],
      "post-update-cmd": [
        "rm public_html/robots.txt"
      ]
    }

The file got removed.

Well. Not until I moved to the live server. On the live server, the script equally didn't work for me.

Hi, all.

Try this:

      "file-mapping": {
           "[web-root]/robots.txt": false
      }

This helped me solve the problem.

best regards

Thanks @savage1974
