Some improvements to DrRacket's "automatic parentheses" mode are now available in the nightly build version and git repository. If you have previous tried auto-parens and abandoned it, or if you have never tried it, please do try it now!
In auto-parens mode, typing a closing parenthesis will skip over an existing one if the cursor is right in front of it. You can also type M+) (meta key + close parens), whether in auto-parens mode or not, to skip right past the closing parentheses of the enclosing expression, or, if the expression is not well-balanced, just forward to the next closing parentheses. This behavior should also work as expected with other closing parenthesis-like symbols, double quotes, and | ... | pairs. There are also some tweaks to the auto-parens mode so that block comments #| ... |# are inserted correctly. Also auto-parens mode has no effect when inside a string literal or comment (you can always use M+( to force a parens pair if you really want one) or when typing a character literal. While 'undo' works properly now for just-inserted () pairs in auto-parens mode, I did not mess at all with delete key behavior. I've left the Paredit-like functionality for another time/person! :-) Have fun, nadeem
