csvReader

auto csvReader(Contents =  string, Malformed ErrorLevel =  Malformed.throwException,  Range,  Separator =  char)(Range input,
                  Separator delimiter =  ',',  Separator quote =  '"',
                  bool  allowInconsistentDelimiterCount =  false) if (isInputRange!Range &&  is(immutable  ElementType!Range ==  immutable  dchar)
     &&  isSomeChar!(Separator)
     && !is(Contents T :  T[U],  U :  string))

Returns an input range for iterating over records found in input.

An optional header can be provided. The first record will be read in as the header. If Contents is a struct then the header provided is expected to correspond to the fields in the struct. When Contents is not a type which can contain the entire record, the header must be provided in the same order as the input or an exception is thrown.

Returns

An input range R as defined by isInputRange. When Contents is a

struct, class, or an associative array, the element type of R is Contents, otherwise the element type of R is itself a range with element type Contents.

If a header argument is provided, the returned range provides a header field for accessing the header from the input in array form.

Throws

CSVException When a quote is found in an unquoted field,

data continues after a closing quote, the quoted field was not closed before data was empty, a conversion failed, or when the row's length does not match the previous length.

HeaderMismatchException when a header is provided but a

matching column is not found or the order did not match that found in the input. Read the exception documentation for specific details of when the exception is thrown for different types of Contents.
