DH_INSTALLDEBCONF(1) Debhelper DH_INSTALLDEBCONF(1)
dh_installdebconf - install files used by debconf in package
build directories
dh_installdebconf [debhelper options] [-n] [-- params]
dh_installdebconf is a debhelper program that is responsible for
installing files used by debconf into package build directories.
It also automatically generates the postrm commands needed to
interface with debconf. The commands are added to the maintainer
scripts by dh_installdeb. See dh_installdeb(1) for an explanation
of how that works.
Note that if you use debconf, your package probably needs to
depend on it (it will be added to ${misc:Depends} by this
program).
Note that for your config script to be called by dpkg, your
postinst needs to source debconf's confmodule. dh_installdebconf
does not install this statement into the postinst automatically
as it is too hard to do it right.
debian/package.config
This is the debconf config script, and is installed into the
DEBIAN directory in the package build directory.
Inside the script, the token #DEBHELPER# is replaced with
shell script snippets generated by other debhelper commands.
debian/package.templates
This is the debconf templates file, and is installed into the
DEBIAN directory in the package build directory.
debian/po/
If this directory is present, this program will automatically
use po2debconf(1) to generate merged templates files that
include the translations from there.
For this to work, your package should build-depend on po-
debconf.
-n, --no-scripts
Do not modify postrm script.
-- params
Pass the params to po2debconf.
-DTOKEN=VALUE, --define TOKEN=VALUE
Define tokens to be replaced inside the maintainer scripts
when it is generated. Please note that the limitations
described in "Limitations in token names" also applies to
tokens defined on the command line. Invalid token names will
trigger an error.
In the simple case, this parameter will cause #TOKEN# to be
replaced by VALUE. If VALUE starts with a literal @-sign,
then VALUE is expected to point to a file containing the
actual value to insert.
An explicit declared token with this parameter will replace
built-in tokens.
Test examples to aid with the understanding:
cat >> debian/config <<EOF
#SIMPLE#
#FILEBASED#
EOF
echo -n "Complex value" > some-file
dh_installdeb --define SIMPLE=direct --define FILEBASED=@some-file
In this example, #SIMPLE# will expand to direct and
#FILEBASED# will expand to Complex value.
It is also possible to set package-specific values for a
given token. This is useful when dh_installdebconf is acting
on multiple packages that need different values for the same
token. This is done by prefixing the token name with
pkg.package-name..
This can be used as in the following example:
cat >> debian/foo.config <<EOF
# Script for #PACKAGE#
#TOKEN#
EOF
cat >> debian/bar.config <<EOF
# Script for #PACKAGE#
#TOKEN#
EOF
cat >> debian/baz.config <<EOF
# Script for #PACKAGE#
#TOKEN#
EOF
dh_installdebconf -pfoo -pbar -pbaz --define TOKEN=default --define pkg.bar.TOKEN=unique-bar-value \
--define pkg.baz.TOKEN=unique-baz-value
In this example, #TOKEN# will expand to default in
debian/foo.config, to unique-bar-value in debian/bar.config
and to unique-baz-value in debian/baz.config.
Note that the #pkg.*# tokens will be visible in all scripts
acted on. E.g. you can refer to #pkg.bar.TOKEN# inside
debian/foo.config and it will be replaced by unique-bar-
value.
The dh_installdebconf will automatically replace the following
tokens inside a provided maintainer script (if not replaced via
-D/--define):
#DEB_HOST_NAME#, #DEB_BUILD_NAME#, #DEB_TARGET_NAME#
These tokens are replaced with the respective variable from
dpkg-architecture(1). In almost all cases, you will want use
the #DEB_HOST_NAME variant in a script to ensure you get the
right value when cross-building.
On a best effort, tokens of this pattern that do not match a
variable in dpkg-architecture(1) will be left as-is.
#ENV.NAME#
These tokens of this form will be replaced with value of the
corresponding environment variable. If the environment
variable is unset, the token is replaced with the empty
string.
Note that there are limits on which names can be used (see
"Limitations in token names").
#PACKAGE#
This token is by default replaced by the package name, which
will contain the concrete script.
Limitations in token names
All tokens intended to be substituted must match the regex:
#[A-Za-z0-9_.+]+#
Tokens that do not match that regex will be silently ignored if
found in the script template. Invalid token names passed to -D
or --define will cause dh_installdebconf to reject the command
with an error in most cases.
