# common/manifests/defines/line.pp -- a trivial mechanism to ensure a line exists in a file
# Copyright (C) 2007 David Schmitt <david@schmitt.edv-bus.at>
# See LICENSE for the full license granted to you.
# Usage:
# line { description:
# file => "filename",
# line => "content",
# ensure => {absent,*present*}
# }
#
# Example:
# The following ensures that the line "allow ^$munin_host$" exists
# in /etc/munin/munin-node.conf, and if there are any changes notify the service for
# a restart
#
# line { allow_munin_host:
# file => "/etc/munin/munin-node.conf",
# line => "allow ^$munin_host$",
# ensure => present,
# notify => Service[munin-node],
# require => Package[munin-node],
# }
#
#
define line($file, $line, $ensure = 'present') {
case $ensure {
default : { err ( "unknown ensure value '${ensure}'" ) }
present: {
exec { "echo '${line}' >> '${file}'":
unless => "grep -qFx '${line}' '${file}'"
}
}
absent: {
$subst_line = regsubst($line,'(/|\.)','\\\1','G')
exec { "sed -i '/${subst_line}/d' '${file}'":
onlyif => "grep -qFx '${line}' '${file}'"
}
}
}
