NullWords

is an option for Read and related functions which specifies whether null words should be taken to exist between repeated word separators.

Details

With the default setting NullWords->False, repeated word separators are treated like single word separators.

Examples

A file containing words separated by colons:

Wolfram Language code: FilePrint["ExampleData/words"]

Repeated colons are treated as single separators:

Wolfram Language code: ReadList["ExampleData/words", Word, WordSeparators -> {":"}]

Repeated colons are taken to have null words in between:

Wolfram Language code: ReadList["ExampleData/words", Word, WordSeparators -> {":"}, NullWords -> True]
