Question 137064 in Javascript Question posted in
A very good W3school tutorial can be found here.

Javascript – How can I create VS Code snippets that consume pre-existing text placed before the snippet prefix and use it in the snippet body?

I want to make snippet for console.log(variable) but instead to have prefix I want to make this with "suffix". Here’s an example:

var name = "Marco";
var car = "Volvo";

name.log > TAB > console.log(name);

When I write my variable "name" after that ".log" like in example above. After that pressing TAB key on keyboard i want to get my "console.log(name);".
When I do it like this: car.log > TAB, I want to get "console.log(car);".

    Looking at the documentation for Snippets, I don’t think what you’re asking for is supported.

    The mechanism for using snippets is based on exact matches of text (the prefix field), and while the variables include things like TM_CURRENT_LINE and TM_CURRENT_WORD, and even given those, I can’t see a way to work them to do what you want.

    The closest I could get was

    "test": {
    "prefix": ".log",
    "body": "console.log(${TM_CURRENT_LINE/^(\s+.*?)?(\w+)\.log(.*)$/$2/})"
}

    But I don’t know how to "consume" / remove the pre-existing text preceding the snippet prefix.

    what you can do is

    • type name
    • select name, useCtrl+D
    • type clog

    clog is the following snippet:

    "consolelog": {
    "prefix": "clog",
    "body": "console.log(${TM_SELECTED_TEXT})"
}
