NAME

       dh_installdebconf - install files used by debconf in package build directories

SYNOPSIS

       dh_installdebconf [debhelperĀ options] [-n] [--Ā params]

DESCRIPTION

       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.

FILES

       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.

OPTIONS

       -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.v 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.

SUBSTITUTION IN MAINTAINER SCRIPTS

       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.
