How to apply multiple transforms to snippet variable

Question

I'm in a file called event-list.tsx, and I'm trying to create a snippet that writes the following code:

const EventList: FC = () => {
  return <div>
    
  </div>;
};

export default EventList;

Thus far, in typescriptreact.json I've written the following snippet setting, which results in awkward-looking code (it puts out const event-list rather than const EventList

"react arrow func component": {
    "prefix": "rafce",
    "body": [
      "const ${TM_FILENAME_BASE}: FC = () => {",
      "  return <div>",
      "    ",
      "  </div>;",
      "};",
      "",
      "export default ${TM_FILENAME_BASE};",
      ""
    ]
  },

I know how to remove the hyphen from the snippet: ${TM_FILENAME_BASE/-//} I also figured out how to capitalize the first character: ${TM_FILENAME_BASE/(^.)/${1:/upcase}/}

But I can't figure out how to apply all three of the changes I want. I know the regular expression needed to capitalize every character that comes after a hyphen (a positive lookbehind), but I don't know how to apply it here. There is nothing in the documentation chapter implying the possibility to chain multiple transforms onto each other.

Answer 1

Try the following global regex

${TM_FILENAME_BASE/(.)([^-]*)-?/${1:/upcase}${2}/g}

Find a part before a - and Upcase the first letter, repeat for the whole string
