Go to a Line

Go to a Line

Hello

Is there any combination of keys to go to a specific line easily ?

Thanks.

No there isn't, but many people use this in their .emacs, which binds
to C-cg

(global-set-key "\C-cg" 'goto-line)


It's worth mentioning that most of the time you don't need to do
this. Compile errors for instance are in many cases parsable by emacs,
and it will just jump to the right line for you.

M-x goto-line
:)

If that's not convenient then simply bind it to some key:
(global-set-key "\C-cg" 'goto-line)
will bind goto-line to C-c g

M-x goto-line

But if line you are looking for comes from the output of a compiler 
(error or warning message), or comes from grep, there is a better way. 
Consider using M-x compile to compile your source; then M-x ` will bring 
you each error in sequence (if you are using ant, make sure to use the 
-emacs command line option).  For grep, M-x grep does approximately the 
same thing.

Or you could just use the default key of

M-g

If that's not convenient then simply bind it to some key:
(global-set-key "\C-cg" 'goto-line)
will bind goto-line to C-c g

That is not the standard binding for M-g.
M-g by default is used to change font or something like that.

It is in xemacs.  If you need to switch back and forth a lot between
the gnuemacs and xemacs, because some hosts only have one and some
only have the other, it's very handy to use the same binding in both.


> M-g by default is used to change font or something like that.

Exactly -- "or something like that".  It's a comparatively obscure
function vis-a-vis goto-line.  How often do you use the standard m-g
in gnuemacs?  For me the answer was "never".  Sounds like the same for
you.  So why not rebind it to goto-line and thereby have the same
binding in both emacs variants at minimal cost?

I'm using emacs 21.2 and that's not the default binding for M-g. For
me M-g does something involving changing the face or something like
that.

I think that C-x g is a good choice because its default behavior of
insert-register can be had with C-x r g, too.

And C-x g is nicely mnemonic.

I use (and like) C-s because I'm "searching for line NNN".

But then you lose the normal binding of C-s: incremental searching. Of
course it depends which you do more often.

Nah: I hacked isearch to do the goto-line thingy instead ;-)

That is _really_ interesting. Does it scroll incrementally to the line
as you type the number? How do you search for numbers in a file? Do you mind
showing us the function you are using :)

Of course ;-)

> How do you search for numbers in a file?

The usual way: `123' matches both the string `123' and the line 123.
The only time when it's inconvenient is when you're looking for line 123 and
the buffer contains heaps of matches for the string `123'.

Also, there's the problem that you might need to hit C-s one extra
time to force isearch to wrap around (or you could have used C-r instead,
but the point is that the relative position of the starting point and the
destination line is relevant).

> Do you mind showing us the function you are using :)

It's a bunch of patches to isearch.el.  I'll see if I can extract the
relevant portions.

Hmmm, how about patching regex.c instead to match a new regular expression:


	\#N	would match the empty string anywhere on line N

Talk about a major gross hack!
I'll only forgive you if you promise you never heard about how regexp
matching is implemented.

How is that any worse than the other regexps that match the empty string at
various buffer positions: ^ $ \` \'

I promise, I don't know.
