[ILUG] vi tip...

[kevin lyda]

for vi users who don't know about recording...

ok, for years i'd accidentally type q and then there'd be this annoying
"recording" thing in the bottom left.  so i finally went and figured out
how to use it.  let's say you have this file:

    http://moo/images/img_0123.jpg
    http://moo/images/img_0145.jpg
    http://moo/images/img_0167.jpg
    http://moo/images/img_0170.jpg
    http://moo/images/img_0212.jpg

and you want to change jpg to jpeg, remove the leading 0, and increment
each number by 10.  i know, a contrived example, but for demo purposes...

the way recording works is you press q<letter><a series of commands>q
to record.  and @<letter> to play the recorded commands back.

so to do this task we'll do this:

    start recording in recording buffer a        qa
    search for jpg                               /jpg<return>
    change it to jpeg                            cwjpeg<esc>
    go to the 0                                  F_l
    delete it                                    x
    increment it by 10                           10<C-a>
    end recording                                q

then rerun the recording with @a for each remaining line:
