My emacs mode at <a href="https://github.com/carl-eastlund/simple-sexp">https://github.com/carl-eastlund/simple-sexp</a> uses meta+[ to bracket-ify the following s-expression. Same for meta+( and meta+{, although it doesn't always get reader macros right such as '( ... ) or #,( ... ). It tends to mis-detect them as non-parenthesized and leave them alone. The workaround is to temporarily put in a space after the reader characters, before the open paren/bracket/brace. This isn't an auto-fix, but hopefully it's a step in the right direction. <div class="gmail_extra"> Carl Eastlund <div class="gmail_quote">On Tue, Nov 20, 2012 at 1:06 PM, Eric Tanter <<a href="mailto:etanter@dcc.uchile.cl" target="_blank">etanter@dcc.uchile.cl</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> (even better would be a way to racketify a whole file at once -- a dream?) -- Éric <div class="HOEnZb"><div class="h5"> On Nov 20, 2012, at 3:01 PM, Eric Tanter wrote: > Hi, > > I'm converting code written with only standard parentheses, introducing squared ones where appropriate. > > This is obviously not very fun (I'm converting all of OOPLAI), and it would be great if there'd be a way to select an open paren and "convert" it so that the matching closing paren is changed automatically. > > Is this feasible? > > Thanks, > > -- Éric > > ____________________ > Racket Users list: > <a href="http://lists.racket-lang.org/users" target="_blank">http://lists.racket-lang.org/users</a> > ____________________ Racket Users list: <a href="http://lists.racket-lang.org/users" target="_blank">http://lists.racket-lang.org/users</a> </div></div></blockquote></div> </div>
