Finding modified sites in buffer?

Finding modified sites in buffer?

[Rjjd]

Is there a way to find what's modified in a buffer, without getting 
dizzy playing with "undo"?

It would be nice to move the cursor to modified sites, or even to the 
last-modified site.

Regards,
Bob

You can compare the recent file with the copy made from the  
(original) file when you started to change it.

M-x diff-buffer-with-file RET

Use `C-c C-c' (diff-goto-source) to jump to the modified lines.

There are some suggestions here:

Also, depending on your needs, you could try using C-u C-SPC to jump
around among the buffer's mark history. Many commands set the mark so
this is quite handy. In my experience, using C-u C-SPC repeatedly
often takes me to places where "things happened".

If your file is stored in cvs (or perhaps other revision control system), 
vc-annotate will colorize differently the source lines that have not
been modified since the different versions.


One trick you can do too, for programming languages that are not case
sensitive, is for example to upper case the sources before you work on
them.  Then everything you type is in lowcase and can be distinguished
from the unmodified code.

You're always typing.
Well, let's see you ignore my
sitting on your hands.

You are a strange man... :)

Anyway, if the poster would accept the above he would probably also
like highlight-changes-mode.

M-x highlight-changes-mode RET

Re: Finding modified sites in buffer?

Pascal resurrects the "good" old days of entering FORTRAN programs onto 
punched cards with IBM 026 keypunch machines.  The concept of lower case 
was strange, alien, and risible.  The machines resided in the basement, 
presumably to avoid shaking the building.

Thanks to everyone.  I'll try all the suggestions.  (Except up-casing, 
which would frighten today's effete compilers.)

Bob

My personal preference is M-x goto-last-change (bound to a key) from:
http://www.cs.virginia.edu/~wh5a/personal/Emacs/goto-chg.el

This package allows you to switch to every change you did, step by step.
