Subject [jira] [Created] (CSV-54) Confusing semantic of the ignore leading/trailing spaces parameters
Date Mon, 12 Mar 2012 13:44:39 GMT
Confusing semantic of the ignore leading/trailing spaces parameters
-------------------------------------------------------------------

                 Key: CSV-54
                 URL: https://issues.apache.org/jira/browse/CSV-54
             Project: Commons CSV
          Issue Type: Bug
            Reporter: Emmanuel Bourg


{{CSVFormat}} has two parameters to control how the leading and trailing spaces around values
are handled, but the actual behavior depends on the value being enclosed in quotes or not.

If the value is not enclosed in quotes, setting {{leading/trailingSpacesIgnored}} to {{true}}
will left or right trim the value. For example with this input (using the default format):

{code}a,  b  ,c{code}

the second value will be equal to {{'b'}}.


But if the value is enclosed into quotes, the value is no longer trimmed:

{code}a," b ",c{code}

this will give {{' b '}}.


With quoted values the parser actually ignores the spaces between the delimiter and the quote.
Thus with this input:

{code}a, " b " ,c{code}

The value returned is {{' b '}}.


If {{leading/trailingSpacesIgnored}} is set to {{false}}, we get instead {{' " b " '}} which
is consistent with RFC 4180.
