Around extension for VS Code

Manage token around regions.

This is a bit of an evil-surround port by an Emacs refugee.

Features

Puts before and after token around selected regions.

Just invoke the around.around command and select the token you want to surround your selection with. Some tokens, like parenthesis, will try to be smart by inserting the correct balancing token. Other tokens, like ", will just surround the region with two identical tokens.

Configuration

around uses the mapping around.pairs to control mappings. Each key in the mapping is a string, and each value is a pair of strings. around uses the mapping as follows.

If the supplied trigger string (possibly multiple characters) is a key in the mapping, then the elements in the value are used to surround the selection.

Otherwise, around processes the trigger string character-by-character. For each character, it checks to see if it is a key in the mapping. If so, the value is used as a two-tuple of prefix and suffix text. If not, then a two-tuple with the character in each position is used. In both cases, the first element in the tuple is appended to the prefix text and the second is prepended to the suffix text.

To bind a specific surrounding to a keyboard shortcut, you can add the following code snippet in your keybindings.json.

[
  {
    "key": "ctrl+shift+9",
    "command": "extension.around",
    "args": {
      "start": "(",
      "end": ")"
    }
  }
]
