|
|

|
|
.Nd create patch files appropriate for pkgsrc
|
|
.Sh SYNOPSIS
|

.Nm

|
.Sh DESCRIPTION
|
|
.Nm
|
|
is a perl script that simplifies creating patches from a changed work
|
|
tree if for each changed file the original was kept with an added
|
|
extension
|
|
.Dq .orig .
|
|
.Pp
|
|
.Nm
|
|
must be called from the package's main directory, that is
|
|
.Pa ${PKGSRC}/category/program .
|
|
It then proceeds to find all files that
|
|
match the pattern
|
|
.Dq *.orig .
|
|
Each of these is then compared to the
|
|
changed file of the same name (with no
|
|
.Dq .orig
|
|
extension) using
|
|
.Xr pkgdiff 1 .
|
|
.Pp
|
|
The resulting patches are saved in the package's patches directory
|
|
(usually
|
|
.Pa patches/ )
|
|
and can be easily compared to the currently existing set using
|
|
.Xr patchdiff 1
|
|
or
|
|
.Ic "cvs diff" .
|
|
.Pp
|
|
If the new patch differs from an existing patch only due to line
|
|
numbers or RCS Ids, the old patch will be kept unchanged.
|
|
.Pp
|
|
Supported options are:
|
|
.Bl -tag -width 3n
|
|
.It Fl c
|
|
Clean up backup patches of previous runs.
|
|
Use this after you're finished working on the patch set and committed
|
|
it.
|
|
.It Fl D
|
|
Use
|
|
.Pa $WRKDIR/.newpatches
|
|
for patches.
|
|
See
|
|
.Fl d
|
|
for more details.
|
|
.It Fl d Ar dir
|
|
Use
|
|
.Ar dir
|
|
for patches.
|
|
Copies any existing patches there on the first run and then
|
|
creates or updates patches only there.
|
|
Use this e.g. if you have a read-only pkgsrc.
|
|
.It Fl h
|
|
Show a short usage.
|
|
.It Fl r
|
|
Revert the changes.
|
|
Removes the new patches and puts the original patches back.
|
|
.It Fl v
|
|
More verbose output.
|
|
.It Fl w
|
|
Look for changes in
|
|
.Pa $WRKDIR
|
|
instead of the default
|
|
.Pa $WRKSRC .
|
|
Usually not needed and slower.
