Description: Return whether any element of list matches the [Unanchored][unanchored] regular expression regex.

list can be a data container or a regular list.

[%CFEngine_function_attributes(regex, list)%]

some() will return as soon as any element matches.

It’s convenient to set a class to not => some(".*", mylist) in order to check if mylist is empty. Since some() returns as soon as possible, that is better than using length() or every() or none() which all must traverse the entire list.

Example:

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

Output:

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