- If we meet a quoted string, the next symbol afterwards
|
||
|
|
(that's not \s, \t) is the delimiter
|
||
|
|
- If we meet a date, the next symbol afterwards is the delimiter
|
||
|
|
|
||
|
|
Date formats
|
||
|
|
- If we meet a column with date formats, check all of them to
|
||
|
|
see if one of the potential months crossing 12. If it does,
|
||
|
|
we now know the format
|
||
|
|
|
||
|
|
It would make things easier to guess the delimiter before
|
||
|
|
doing the actual parsing.
|
||
|
|
|
||
|
|
General rules:
|
||
|
|
- Quoting is allowed, e.g: "Col 1",123,321
|
||
|
|
- Quoting is optional, e.g.: Col1,123,321
|
||
|
|
- Doubble quoting is escaping, e.g. "Col ""Hello world""",123
|
||
|
|
- Spaces are considered part of the data: Col1 ,123
|
||
|
|
- New line is always the row delimiter
|
||
|
|
- Potential column delimiters are , ; \t
|
||
|
|
- First row may optionally contain headers
|
||
|
|
- The last row may or may not have a row delimiter
|
||
|
|
- Comments are optionally supported, in which case the comment
|
||
|
|
must start at the first column, and the rest of the line will
|
||
|
|
be ignored
