Options:
-h, --help Print this message.
-V, --version Print the package version.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
-
If the split separator is a regular expression, ensure that the
splitoption is either properly escaped or enclosed in quotes.# Not escaped... $ echo -n $'beEp booP\nFOO' | is-constantcase --split /\r?\n/ # Escaped... $ echo -n $'beEp booP\nFOO' | is-constantcase --split /\\r?\\n/
-
The implementation ignores trailing delimiters.

trueTo use as a standard stream,
$ echo -n 'beep Boop' | is-constantcase
falseBy default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.
