"port diff" command to help Portfile writer make patches

[ebgssth@…]

port diff command is a new sub-command of port command which works live below.

$ port edit portname # make changes
$ port diff portfile # invokes diff -u Original-Portfile Edited-Portfile

This functionality makes patches for Portfile easier.

We are currently using Subversion instead.

svn diff Portfile

If you have some more ideas on how the "save an original" phase would work, or how to resolve edits by multiple authors (so that you diff against the recent version) then reopen ticket...

Until then, use subversion ?

[ebgssth@…]

edits by multiple authors should be resoved by subversion.

port diff helps casual portfile writer, who doesn't svn co macports src, edit portfiles.

"save an original" phase shouldn't be so difficult. Just rename the original Portfile.orig, and port diff checks that whether there's a modified file or not and if there is, Just invoke diff portfile.orig portfile | $PAGER
