Michael Graessle created CSV-171:
------------------------------------
Summary: Negative numeric values in the first column are always
quoted in minimal mode
Key: CSV-171
URL: https://issues.apache.org/jira/browse/CSV-171
Project: Commons CSV
Issue Type: Bug
Reporter: Michael Graessle
Priority: Minor
Negative Numeric values are always quoted in minimal mode if (and only if) they
are in the first column.
i.e.
long,lat,data
"-92.222",43.333,3
Looking at the code, this is by design but seem to be for an unknown reason.
>From v1.2 CSVPrinter line 230:
// TODO where did this rule come from?
if (newRecord && (c < '0' || (c > '9' && c < 'A') || (c > 'Z' && c < 'a') || (c
> 'z'))) {
quote = true;
} else ...
I propose this rule to either be remove or at a minimum be changed to:
// TODO where did this rule come from?
if (newRecord && (c !='-' && c < '0' || (c > '9' && c < 'A') || (c > 'Z' && c <
'a') || (c > 'z'))) {
quote = true;
} else ...
