how to compare two different regions in the same files?

[yixiao...@gmail.com]

Hi,

I want to compare the text in two different parts of the same file.
Instead of cut and paste to create two new files, are there any ways
to directly compare the two parts in vim? I am using vim 7.2.

Thanks

Frank

Have you tried :help :split

The split will split the file into two windows. How can I compare the
two regions instead of reading it line by line.

Thanks

You can't. Not unless you put the contents of those two windows
into two, new buffers and diff the two buffers. But then any
changes you make to those buffers are not reflected back to the
original file. It would be a nice feature to have, though.

Try the NrrwRgn Plugin on http://github.com/chrisbra/NrrwRgn

I have just added an experimental feature, that allows to have a new
Narrowed Window per file.

The idea is to create a new Narrow Region for each region and file you
want to diff. Be sure to set g:nrrw_rgn_sepwin to 1 so the plugin will
create for each buffer an extra Narrow Window. Then you can diff both
Narrow Windows and whenever you write the narrowed Windows, the changes
will be taken back into the original file.

regards,
Christian

Very nice! I've just played with it a little and haven't tried
making changes with it, but I like it so far. Thanks.
