[%CFEngine_function_prototype(filename, regex, groupsize)%]
Description: Returns the current host's partition peer leader.
groupsize 3 and the file
a b c # this is a comment d e
The peer leader of host
b will be host
Given a list of host names in
filename, one per line, and excluding
comment lines starting with the [unanchored][unanchored] regular
regex, CFEngine partitions the host list into groups of
groupsize. Each group's peer leader is the first host in the
comment field is a multiline regular expression and will strip out
unwanted patterns from the file being read, leaving unstripped characters to be
split into fields. Using the empty string (
"") indicates no comments.
The current host (unqualified or fully qualified) should belong to this file if it is expected to interact with the others. The function fails otherwise.
If the current host name (fully qualified or unqualified) is the peer
leader, the string
localhost is used instead of the host name.
[%CFEngine_function_attributes(filename, regex, groupsize)%]
groupsize must be between 2 and 64 to avoid nonsensical promises.
