Function Documentation

find_end_of_quoted_field()

std::optional< int64_t > blender::csv_parse::detail::find_end_of_quoted_field	(	Span< char >	buffer,
		int64_t	start,
		char	quote,
		Span< char >	escape_chars )

Find the index of the quote that ends the current field.

Parameters

start	The index after the opening quote.
quote	The quote character that ends the field.
escape_chars	The characters that may be used to escape the quote character.

Returns

Index of the quote character that ends the field, or std::nullopt if the field is malformed and does not have an end.

find_end_of_simple_field()

int64_t blender::csv_parse::detail::find_end_of_simple_field	(	Span< char >	buffer,
		int64_t	start,
		char	delimiter )

Find the index that ends the current field, i.e. the index of the next delimiter of newline. The start index has to be the index of the first character in the field. It may also be the end of the field already if it is empty.

Parameters

start	The index of the first character in the field. This may also be the end of the field already if it is empty.
delimiter	The character that ends the field.

Returns

Index of the next delimiter, a newline character or the end of the buffer.

parse_record_fields()

std::optional< int64_t > blender::csv_parse::detail::parse_record_fields	(	const Span< char >	buffer,
		const int64_t	start,
		const char	delimiter,
		const char	quote,
		const Span< char >	quote_escape_chars,
		Vector< Span< char > > &	r_fields )

Finds all fields for the record starting at the given index. Typically, the record ends with a newline, but quoted multi-line records are supported as well.

Returns

Index of the start of the next record or the end of the buffer. #std::nullopt is returned if the buffer has a malformed record at the end, i.e. a quoted field that is not closed.
