Bug #15770
Updated by skyksandr (Aleksandr Kunin) about 5 years ago
It works on 2.5.\*, but doesn't work on 2.6.\*
```
require 'csv'
require 'date'
counter = 0
CSV.foreach('./05-31-20.CSV', skip_lines: /^[^0-9]{4}/) do |row|
time = row[0]
p time if time.length < 23
counter += 1
end
p "Processed: #{counter} lines"
```
And the result is:
```
"03-09T09:40:04.00Z"
"Processed: 4424 lines"
```
So there are two problems:
1. Line 4424 got corrupted by slicing 5 symbols ("2019-")
2. Not whole file is parsed, total number of lines: **4497**
EDIT:
With regex `/^(?![0-9]{4})/` in addition to corrupt first field parser hangs in infinite loop.
