NAME

       cdist-type__key_value - Change property values in files

DESCRIPTION

       This cdist type allows you to change values in a key value based config file.

REQUIRED PARAMETERS

       file   The file to operate on.

       delimiter
              The delimiter which separates the key from the value.

OPTIONAL PARAMETERS

       state  present  or  absent,  defaults  to  present.  If present, sets the key to value, if
              absent, removes the key from the file.

       key    The key to change. Defaults to object_id.

       value  The value for the key. Optional if state=absent, required otherwise.

       comment
              If supplied, the value will be inserted before the line with the key, but  only  if
              the  key  or  value  must be changed.  You need to ensure yourself that the line is
              prefixed with the correct comment sign. (for example # or ; or wathever ..)

       onchange
              The code to run if  the  key  or  value  changes  (i.e.  is  inserted,  removed  or
              replaced).

BOOLEAN PARAMETERS

       exact_delimiter
              If supplied, treat additional whitespaces between key, delimiter and value as wrong
              value.

MESSAGES

       remove Removed existing key and value

       insert Added key and value

       change Changed value of existing key

       create A new line was inserted in a new file

EXAMPLES

          # Set the maximum system user id
          __key_value SYS_UID_MAX --file /etc/login.defs --value 666 --delimiter ' '

          # Same with fancy id
          __key_value my-fancy-id --file /etc/login.defs --key SYS_UID_MAX --value 666 \
             --delimiter ' '

          # Enable packet forwarding
          __key_value net.ipv4.ip_forward --file /etc/sysctl.conf --value 1 \
             --delimiter ' = ' --comment '# my linux kernel should act as a router'

          # Remove existing key/value
          __key_value LEGACY_KEY --file /etc/somefile --state absent --delimiter '='

MORE INFORMATION

       This type try to handle as many values as possible, so it doesn't  use  regexes.   So  you
       need to exactly specify the key and delimiter. Delimiter can be of any length.
