if

Many settings like shell commands, packages or targets support an if property, which contains JavaScript code which indicates if a setting is currently available/usable or not.

{
    "deploy.reloaded": {
        "executeOnStartup": [
            {
                "command": "npm install",
                "if": " !require('fs').existsSync( $v['workspaceroot'] + '/node_modules' ) "
            }
        ]
    }
}

The upper shell command is only executed, if NO node_modules folder is found in the root directory of the underlying workspace.

Constants

$ctx

A special object of the underlying setting / object.

$v

An object that stores all placeholders, which are available in that context as object.

The variable names can be accessed as properties in lower case format.

Functions

$e

Short version of JavaScript's eval.

$r

Short version of NodeJS's require, which includes a module the same way, as you are working as extension code. This makes extension modules and modules from package.json also available for you
