String#split is inconsistent with empty string and negative limit
Added by Conrad.Irwin (Conrad Irwin) about 14 years ago.
Updated over 4 years ago.
Description
Currently works like this:
"".split(",", -1) # => []
According to the documentation, blank fields should not be stripped when a negative offset is provided. I expect:
"".split(",", -1) # => [""]
- Description updated (diff)
I think Ruby thinks "" has no fields, not one field which have empty string.
So, "".split(",", -1) should return [].
Documentation issue, maybe.
- Category changed from core to doc
- Assignee set to drbrain (Eric Hodel)
I will add a note to the documentation to cover the behavior of empty strings.
- Status changed from Open to Assigned
- Status changed from Assigned to Closed
- % Done changed from 0 to 100
This issue was solved with changeset r35275.
Conrad, thank you for reporting this issue.
Your contribution to Ruby is greatly appreciated.
May Ruby be with you.
