allows you to get context style or plain diffs from mkpatches or pkgdiff, instead of the default unified format. Sometimes it's very nice to be able to look at a different diff format.

.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility runs
|
|
.Xr diff 1
|
|
on the named files, and generates output on stdout that is appropriate
|
|
to be put as patch file into pkgsrc. An empty
|
|
.Nx
|
|
RCS ID is output
|
|
first, and some effort is made to ensure that the generated patch does
|
|
not include any RCS IDs.
|
|
.Pp
|
|
.Ar options
|
|
can be any options that are allowed for
|
|
.Xr diff 1 .
|
|
.Sh ENVIRONMENT
|
|
.Ss PKGDIFF_FMT
|
|
The flags passed to
|
|
.Xr diff 1
|
|
when generating patches.
|
|
If not set, the flags
|
|
.Fl u
|
|
and
|
|
.Fl p
|
|
are used.
|
|
Though only unified format patches are used in pkgsrc as proper
|
|
patches, sometimes it can be useful to have context or plain diffs
|
|
available.
