Is there a good Vi(m) command for transposing arguments in a function call? Bonus points for Emacs

Question

For example if I have some code like:

foo = bar(\"abc\", \"def\", true, callback);

Is there a nice command to move true to the 1st or 2nd posit

Answer 1

Transposing previous (Ctrl-t p) and next (Ctrl-t n) argument ... add the following into your .vimrc file:

map p ?,\\|(wd/,\\|)?,\\|("_dw?,\\|(a, ?,P/,w
map n ?,\\|(wv/,d"_dw/\\,\\|)i, "?,?,\\|(w
