Emacs: adding 1 to every number made of 2 digits inside a marked region
- by WizardOfOdds
Imagine I've got the following in a text file opened under Emacs:
some 34
word 30
another 38
thing 59
to 39
say 10
here 47
and I want to turn into this, adding 1 to every number made of 2 digits:
some 35
word 31
another 39
thing 60
to 40
say 11
here 48
(this is a short example, my actual need is on a much bigger list, not my call)
How can I do this from Emacs?
I don't mind calling some external Perl/sed/whatever magic as long as the call is made directly from Emacs and operates only on the marked region I want.
How would you automate this from Emacs?
I think the answer I'm thinking of consist in calling shell-command-on-region and replace the region by the output... But I'm not sure as to how to concretely do this.
