how to put increased number for multiline selection in visual studio code

Question

I want to add increased number for multi selected caret in visual studio code. now, When I type it write same words.

But I would like to add increased number by some shortkey so that I don't need to update each one manually. Preferred result should be like this.

I want to know if this is possible in vs code.

Thanks

You do not need an extension for your use case, although that may make it easier. Here is how to do it without an extension.

1. Find: (?<=index:\s*)\d+ : this selects only the digits following index: .
2. Alt+Enter will select all those digits.

Now you can run a simple snippet to replace those digits with an increasing number that could be 0-based or 1-based. Make this keybinding to insert the snippet (in your keybindings.json):

{
  "key": "alt+m",        // whatever keybinding you want
  "command": "editor.action.insertSnippet",
  "args": {
    "snippet": "$CURSOR_NUMBER"  // this will increment and is 1-based
  }
}

3. Trigger the above keybinding. Demo:

Here is an extension approach, using an extension I wrote, Find and Transform, that makes this easy. Make this keybinding:

{
  "key": "alt+m",        // whatever keybinding you want
  "command": "findInCurrentFile",
  "args": {
    "find": "(?<=index:\\s*)\\d+",   // same find regex
    "replace": "${matchNumber}",     // this variable will increase, 1-based
    "isRegex": true
  }
}

That combines the find and replace in one step.

Here is another method so you do not need to hardcode the starting point.

{
  "key": "alt+m",                  // whatever keybinding you want
  "command": "findInCurrentFile",
  "args": {
    "preCommands": [
      "editor.action.addSelectionToNextFindMatch", 
      "editor.action.clipboardCopyAction"
    ],
    "find": "(?<=index:\\s*)\\d+",
    "replace": [
      "$${",
        // whatever math you want to do here
        "return Number(${CLIPBOARD}) + ${matchIndex};",
      "}$$",
    ],
    "isRegex": true,
    "postCommands": "cancelSelection"
  }
}

Put the cursor next to or select the number you want as the starting point. The number could be anywhere in the document actually.

You can do it with Increment Selection or Text Pastry
