[%CFEngine_function_prototype(filename, regex, groupsize)%]

Description: Returns the current host’s partition peers (excluding it).

So given groupsize 3 and the file

a b c # this is a comment d e

The peers of host b will be a and c.

Given a list of host names in filename, one per line, and excluding comment lines starting with the [unanchored][unanchored] regular expression regex, CFEngine partitions the host list into groups of up to groupsize. Each group’s peer leader is the first host in the group.

The current host (unqualified or fully qualified) should belong to this file if it is expected to interact with the others. The function returns an empty list otherwise.

[%CFEngine_function_attributes(filename, regex, groupsize)%]

groupsize must be between 2 and 64 to avoid nonsensical promises.

Example:

Prepare:

[%CFEngine_include_snippet(peers.cf, #+begin_src prep, .*end_src)%]

Run:

[%CFEngine_include_snippet(peers.cf, #+begin_src cfengine3, .*end_src)%]

Output:

[%CFEngine_include_snippet(peers.cf, #+begin_src\s+example_output\s, .end_src)%]
