ToggleCase

Toggle case of the selected string:

Ctrl+; Linux
⌘+; MacOS

in the following order:

nocase -> camelCase
camelCase -> snake_case
snake_case -> kebab-case
kebab-case -> camelCase

If you wish to overwrite the default shortcut, search for editor.togglecase.

Features

Works with multi-select and multiple carets
Per languageId customization

Extension Settings

Only setting present (and configurable for different languages) is regexp of characters that can occur as second and second last in the variable name.

togglecase.pattern: "[0-9]|[a-z]|[A-Z]|_|-"

with the following defaults:

lowercase a-z letters
uppercase A-Z letters
digits 0-9
hyphen -
underscore _

Letters come from the english alphabet.

Custom per-language configuration - let's assume that you're crazy enough to use $ inside your variable names, for example btc_$_price (please don't).

In that case, you could extend the default RegExp with an additional |\$:

"configurationDefaults": {
  "[javascript]": {
    "togglecase.pattern": "[0-9]|[a-z]|[A-Z]|_|-|\$"
  }

It might be useful for some other languages, hence it's configurable.

Known Issues

Toggle works only when caret is at least on the third-last character of the targeted variable.

In the examples below, the | represents current carret(s).

Does not work

{
  "first_nam|e": "Jon",
  "last_nam|e": "Doe",
  "user_nam|e": "jondoe",
  "phone_numbe|r": "555666777"
}

Does work

{
  "first_na|me": "Jon",
  "last_na|me": "Doe",
  "user_na|me": "jondoe",
  "phone_numb|er": "555666777"
}

Fix for this behavior is welcome.
