Identify syntax region under cursor

Question

I'm writing a VimL function that needs to behave differently for different filetypes. I know I can use &filetype to detect that, but my issue is with files that have embedded languages. Let's say I have this:

<html>
<head>
  <style>
    div {
      text-color: red;
    }
  </style>
</head>
<body>
  <div>Some text</div>
</body>
</html>

If the cursor is inside the style tag, I want to know that I'm dealing with CSS. Is this possible?

synIDattr(synID(line("."), col("."), 0), "name") will return css* (like cssStyle or cssDefinition) inside the style tag.

If this is something you do often then Tim Pope's scriptease.vim plugin provides zS mapping. Poor man's mapping: nnoremap zS :echo join(reverse(map(synstack(line('.'), col('.')), 'synIDattr(v:val,"name")')),' ')<cr> – Peter Rincker Mar 24 '17 at 21:27
seems to return blank for me. – artfulrobot Jan 13 '23 at 13:16
@artfulrobot you need to have ft defined for it to work (for example in a syntax highlighted file) – laktak Jan 13 '23 at 19:48
yeah it is defined. – artfulrobot Jan 16 '23 at 09:32
