Snippet variables kebabcase transform

[RayPS]

Currently we have upcase, downcase, capitalize, camelcase, pascalcase transforms.

Example for adding kebabcase transform:

TM_FILENAME_BASE is UserProfileItem

"${TM_FILENAME_BASE/(.*)/${1:/kebabcase}/}"

Result:

user-profile-item

Also suggesting other cases that could be useful.

Case	Result	Already Have
camelcase	userProfileItem	✓
pascalcase	UserProfileItem	✓
kebabcase	user-profile-item	✗
snakecase	user_profile_item	✗
dotcase	user.profile.item	✗
slashcase	user/profile/item	✗
titlecase	User Profile Item	✗
sentencecase	User profile item	✗

In the meantime as a workaround, this extension Find and Transform use the built-in editor.action.transformToKebabcase command (in a keybinding, not a snippet) together with any snippet variable, like ${fileBasenameNoExtension} to accomplish what you want. For example, this keybinding (in keybindings.json) would insert the kebabed-case version of ${fileBasenameNoExtension} at the cursor:

{
  "key": "alt+s",         // whatever keybinding you want 
  "command": "findInCurrentFile",
  "args": {
    "replace": "${fileBasenameNoExtension}",
    "postCommands": ["editor.action.transformToKebabcase", "cancelSelection"]
  },
}

The following rules are not implemented by chatGPT. Need official native support:

Input:

• foo__bar-baz-qux
• FooBarBazQux
• fooBarBazQux
• foo-bar-baz-qux
• foo_bar_baz_qux
• foo.bar.baz.qux
• FOO_BAR_BAZ_QUX
• foo/bar/baz/qux
• foo bar baz qux

Output: foo-bar-baz-qux
