Define text object that depends on the current operator

Question

I'm curious if it is possible to make a text object aware of its operator. In particular, I am writing a text object for LaTeX environments, where I want different behaviour depending on the operator. For instance, consider the following LaTeX snippet:

\begin{example}
  Hello world
\end{example}

Here it is most convenient of die deletes the content in a linewise fashion, whereas cie deletes "Hello world", but preserves the indentation, i.e., gives

\begin{example}
  |
\end{example}

where | is the cursor.

Answer 1

The following example comes close to what you are asking for:

onoremap <expr> w '<esc>' . v:operator . v:count1 . (v:operator ==# 'd' ? 'aw' : 'iw')

It creates a textobject w that is either aw, in case it is used by the delete operator, that is, dw = daw, or iw otherwise, for example cw = ciw.
