dbs-edit-patch -h|--help

DESCRIPTION

dbs-edit-patch is script to generate or modify patches for Debian source-packages in DBS format.

OPTIONS

-h, --help

Show summary of options.

-t dir, --tmpdir=dir

Directory for the temporary files, default is /tmp or if set $TMP.

-s dir, --sourcedir=dir

Top level directory of the debian-package source-tree, default is the present working directory.

-P dir, --sourcepatchdir=dir

Directory containing upstream patches.

-T dir, --sourcetardir=dir

Directory containing the upstream tarball.

-p level, --strip=level

Striplevel -p of patch (Option -p of diff(1)), accepted values are 0 and 1, default is 0.

debian/vars

dbs-edit-patch will automatically use variables defined in the optional debian/vars file.

When a file debian/vars.in exists and debian/vars either does not exist or is older than any of the following files: debian/vars.in, debian/changelog, debian/rules or debian/control, then dbs-edit-patch will try updating the vars file by running the following command

make -f debian/rules -W debian/vars.in debian/vars

EXAMPLES

Edit the 021_debian patch of Heimdal:

~/heimdal-0.3d> dbs-edit-patch -t/tmp 021_debian
Extracting source heimdal-0.3d.tar.gz ... successful.
Applying patch 001_replay ... successful.
etc.
Copying heimdal-0.3d to heimdal-0.3d-old ... successful.
Applying patch 021_debian ... successful.

Edit files under /tmp/021_debian/heimdal-0.3d as required, then put a short description into /tmp/021_debian/patch-description if desired, and finally execute /tmp/021_debian/dbs-update-patch to save the results.

Technical note: dbs-edit-patch extracts all patches before 021_debian into /tmp/021_debian/heimdal-0.3d, copies the result to /tmp/021_debian/heimdal-0.3d-old, and applies the last patch 021_debian (if it exists). Also, it creates a shell script which will create the diff between the old and new directories:

~/heimdal-0.3d> ls -la /tmp/021_debian
total 12
