Question

I have a document with contains ## for list sign. I want to replace ## with order numbers.

first matched ## -> to 1.
second matched ## -> 2.

Is this possible to do in an editor, like VS Code etc.

@Biffen Emacs is a good editor. But it's not ease to use on windows or Mac. — John Zhang, Mar 15 '23 at 15:01

You can use the extension Regex Text Generator

The generate expression you want is: {{=i+1}}

You can do this without an extension by first selecting all the ##'s you want to change. One way is by a Find: ## and then Alt+Enter to select all those matches.

Then run this keybinding:

 {
  "key": "alt+w",   // whatever keybinding you want
  "command": "editor.action.insertSnippet",
  "args": {
    "snippet": "${CURSOR_NUMBER}"    // 1-based, CURSOR_INDEX is 0-based
  },
  "when": "editorHasSelection"
},

To combine the find, select all and replace in one step you can use the extension Find and Transform, which I wrote. Here is a sample keybinding that will do what you want (in your keybindings.json):

 {
  "key": "alt+c",            // whatever keybinding you want
  "command": "findInCurrentFile",
  "args": {
    "description": "increment hashes",
    "find": "##",
    "replace": "${matchNumber}",   
    "postCommands": "cancelSelection"
  }
 }

${matchNumber} is 1-based, ${matchIndex} is 0-based.
