Inserting n,...,n+k number in k lines in visual studio code

Question

I want to insert [11,12,...,20] in 10 lines of vscode editor, somehow I want to simulate iota functionality of golang in vscode editor, for example let assume we had this lines in vscode editor:

line1 xxxxx
line2 xx
line3 xxxxxxxx
.
.
.
line10 xxx

I want to add [11,12,...,20] to end of each line with vscode custom snippets!

Desired output will be:

line1 xxxxx11
line2 xx12
line3 xxxxxxxx13
.
.
.
line10 xxx20

Is it possible with vscode provided snippets or we should develop an extension for this purpose ? Note that the init value = 11 and the count=10 are user defined and not known in the begining.

It's obviously possible since it can be done using multiple cursors. — md2perpe, Feb 28 '22 at 12:12
How you want add from 11 to 20, this is example the numbers count and init is unknown ? — S4eed3sm, Feb 28 '22 at 12:41

Here's an example how you can append numbers to the ends of the first 10 lines (or to the existing lines if there are fewer).

Excerpt from package.json:

    "activationEvents": [
        "onCommand:stackoverflow-71294699.appendNumbers"
    ],
    "contributes": {
        "commands": [
            {
                "command": "stackoverflow-71294699.appendNumbers",
                "title": "Append numbers"
            }
        ]
    },

extension.ts:

import * as vscode from 'vscode';

export function activate(context: vscode.ExtensionContext) {
    context.subscriptions.push(
        vscode.commands.registerCommand('stackoverflow-71294699.appendNumbers',
            async function () {
                const editor = vscode.window.activeTextEditor;
                if (!editor) {
                    return;
                }

                await editor.edit((editBuilder) => {
                    for (let i=0; i<10; i++) {
                        if (i >= editor.document.lineCount) {
                            break;
                        }

                        const line = editor.document.lineAt(i);
                        editBuilder.insert(
                            new vscode.Position(i, line.text.length),
                            "" + (10+i)
                        );
                    }
                });
            })
    );
}

export function deactivate() {}

Using an extension I wrote you can do math easily on lines/selections/document, etc. The extension is Find and Transform.

With this keybinding (or it could be a setting):

{
  "key": "alt+r",                 // whatever keybinding you want
  "command": "findInCurrentFile",
  "args": {
    
    "find": "(?<=\\w)$",
    "replace": "$${ return ${matchNumber} + 10 }$$",
    "isRegex": true,
    "restrictFind": "selections"
}

find: (?<=\\w)$ matches end of line where there is text

or

find: $ matches end of all lines - blank or not

replace: $${ return ${matchNumber} + 10 }$$ will add to the matchNumber - which starts at 1 - and it will go on the end of the line

restrictFind: selections Do this only in any selections

Demo:

So select as many lines as you want. And replace 10 in the keybinding with whatever you want to add to each match.
