How do I use the '$' in a snippet in visual studio code?

  • 772

I am trying to create a php snippet in visual stydio code. I want that snippet to already include a variable, but when I fire the snippet it removes the dollar sign from the variables:

code snippet:

    "Print to console": {
        "prefix": "rick",
        "body": [
            "$rick = $1;",
            "dump($rick);",
        ],
        "description": "hace un dump"
    }

code resulting from firing the snippet:

rick = ;
dump(rick);

It doesn't work for me to use '\' as an escape character:

"Print to console": {
        "prefix": "rick",
        "body": [
            "\$rick = $1;",
            "dump(\$rick);",
        ],
        "description": "hace un dump"
    }

it gives me the following error:

Invalid escape character in string.json(261)

    To be able to correctly escape the symbol $in the snippetI recommend two options:

    1. put double $$:

      "Print to console": {
    "prefix": "rick",
    "body": [
        "$$rick = $$1;",
        "dump($$rick);",
    ],
    "description": "hace un dump"
}

    2. Put double slash \\:

      "Print to console": {
    "prefix": "rick",
    "body": [
        "\\$rick = \\$1;",
        "dump(\\$rick);",
    ],
    "description": "hace un dump"
}
