Hello,
I am trying to write a function that would work like query-replace-regexp,
but instead of replacing each match with a fixed string, I want the matched
numbers to be increased by 3.
Or, easier, I have a file that looks like this:
20 1 23523
20 2 23874
20 3 23898
...
and I want to increase all the numbers in the third column by a certain
amount, say 3, from (point) to (point-max). A Perl script would not help,
because I need to do it several times and from different points.
I started following a tutorial in emacs-lisp, and also tried looking at the
code of some ".el" files, but it seems that I am still far from being able
to do such a simple(?) function. This post is in case some charitable
emacs-lisp expert soul knows how to do it.
Thanks,
Jordi
