This is pretty simple, for example:
$ export PKGSRCDIR="/usr/pkgsrc"
$ cd ${PKGSRCDIR}/pkgtools/pkgdiff
$ make install
[...]
$ cd ../../misc/dvtm
$ make extract
[...]
$ pkgvi $(make show-var VARNAME=WRKSRC)/
[...]
[hey, it's our friend, vi(1) (or the ${PKGEDITOR} or ${EDITOR}
variable)! :-)]

/* Why dvtm doesn't like getopt(3)? */
[ESC]
:wq

pkgvi: File was modified. For a diff, type:
pkgdiff /usr/pkgsrc/misc/dvtm/work/dvtm-0.4.1/dvtm.c
$ pkgdiff /usr/pkgsrc/misc/dvtm/work/dvtm-0.4.1/dvtm.c # we'd like to
see our patch
[...]
$NetBSD$
--- /usr/pkgsrc/misc/dvtm/work/dvtm-0.4.1/dvtm.c.orig 2008-05-10
18:39:01.000000000 +0200
[...]
$ mkpatches
$ cp $(make show-var VARNAME=WRKDIR)/.newpatches/* patches
$ cat patches/patch-ab
$NetBSD$
--- dvtm.c.orig 2008-05-10 18:39:01.000000000 +0200
However, this is the MAINTAINER-way, if you'd like to patch it with the
pkgsrc-user way (for example on dvtm we need to adjust the config.h file
for the customization):
$ cd ${PKGSRCDIR/misc/dvtm
$ mkdir -p ${PKGSRCDIR}/localpatches/misc/dvtm
$ echo "LOCALPATCHES = /usr/pkgsrc/localpatches" >> /etc/mk.conf
$ cp $(make show-var VARNAME=WRKSRC)/config.h \
> $(make show-var VARNAME=LOCALPATCHES)/misc/dvtm/config.h.orig
$ cd $(make show-var VARNAME=LOCALPATCHES)/misc/dvtm
$ vi config.h.orig
[...]
:24
:s/RED/CYAN/
:wq config.h
[...]
$ diff -u config.h.orig config.h > patch-co
$ cd ${PKGSRCDIR}/misc/dvtm
$ make install # Finally we can enjoy dvtm with the cyan borders :-)
The "magic" variable in this example is LOCALPATCHES, the LOCALPATCHES
is like category/package/patches directory. However, the first is for
the MAINTAINER and MAINTAINERs usually patch the source only for
portability or security, the latter is for the pkgsrc user, that for
example would like a cyan border. :-)
For more information please read ``The pkgsrc guide''...
...and happy (pkg)diff(1)ing! :-)
Ciao, Leonardo
