Why google? Here's the home page: http://code.google.com/p/autopair/

And yes, it's the most popular package for this purpose.

I especially like the newline behavior (the fourth bullet point).

The built-in electric-pair-mode does that.

Thanks for your kind replies.

I tried the built-inelectric-pair-mode and it does what I want.

With kind regards,

(originally forgot to cc: help-gnu-emacs@gnu.org)

I'd just like to add that autopair:

* is now hosted at github.com/capitaomorte/autopair
* out of the box, does  a bit more than electric-pair-mode, like
deleting 0-width paren pairs when backspacing and helping to keep the
buffer balanced (for example typing 3 opening "{" consecutively makes
"{{{}}}" instead of electric pair's "{{{}".
* can be customized to behave differently in comments and strings,
pair characters, and more

I'm quite positively surprised how electric-pair-mode has evolved
though, but still find it awkward in how it sometimes pairs and
sometimes doesn't.

Electric braces

[Guido Van Hoecke]

Hi,

When using 'electric braces' in Visual Studio, MonoDevelop and other
tools, I like the behaviour where the closing brace is auto-detected.

(In the example, I show the insertion point as a bar)
If I type

if (|

the screen shows

if (|)

I then key in my test expression, say isFalse (or whatever):

if (isFalse|)

At this point, Visual studio and MonoDevelop realise that the next ')'
key I hit, really represents the ')' which is already there. It does not
add an additional ')' :

if (isFalse)|

But in Emacs, currently using cperl, but also when using c#-mode, or
IIRC ruby-mode, emacs does add an additional ')' which leads to
following erroneous code:

if (isFalse)|)

I am pretty cinfident that Emacs can mimic the VS/MD behaviour. I just
did not find yet how to request it from good old Emacs.

Thanks in advance for any suggestions,




Guido

paredit-mode does that, but perhaps some more since it's for lisp
editing.  You'll want to extract parts of it.
