# @FUNCTION: split()
|
|
#
|
|
# Split a string variable into a string array/list variable.
|
|
#
|
|
# Usage::
|
|
#
|
|
# split("<inputStr>" "<sepStr>" <outputStrListVar>)
|
|
#
|
|
# The ``<sepStr>`` string is used with ``string(REGEX ...)`` to replace all
|
|
# occurrences of ``<sepStr>`` in ``<inputStr>`` with ``";"`` and writing into
|
|
# ``<outputStrListVar>``.
|
|
#
|
|
# WARNING: ``<sepStr>`` is interpreted as a regular expression (regex) so keep
|
|
# that in mind when considering special regex chars like ``'*'``, ``'.'``,
|
|
# etc!
|
|
