[Message part 1 (text/plain, inline)]

Hi there!

Attached is a patch that enables transpose-sexps for tree-sitter enabled
modes.

This function will swap the node _before_ node-at-point with the node
_after_, so it would do something like:

       foo a|nd bar => bar and foo|

or
       foo(a + 4,| y + c * b, b, d); => foo(y + c * b, a + 4|, b, d);

It will _not_ try to swap things that are not siblings.  I think that
makes sense in the case of non-lisp languages, since _most_ places you
can transpose-sexps you will end up with broken code.

What do you think?  I think this makes sense on the master branch, not
release.

Theo
