This method is called when a parse error is found.

ERROR_TOKEN_ID is an internal ID of token which caused error. You can get string representation of this ID by calling token_to_str.

ERROR_VALUE is a value of error token.

value_stack is a stack of symbol values. DO NOT MODIFY this object.

This method raises ParseError by default.

If this method returns, parsers enter “error recovering mode”.

Replace %w+% into the environment value of what is contained between the %‘s This method is used for REG_EXPAND_SZ.

For detail, see expandEnvironmentStrings Win32 API.

Returns true if this is a header row, false otherwise.

Returns true if this is a field row, false otherwise.

Returns a duplicate of self, in row mode (see Row Mode):

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
table.mode # => :col_or_row
dup_table = table.by_row
dup_table.mode # => :row
dup_table.equal?(table) # => false # It's a dup

This may be used to chain method calls without changing the mode (but also will affect performance and memory usage):

dup_table.by_row[1]

Also note that changes to the duplicate table will not affect the original.

Sets the mode for self to row mode (see Row Mode); returns self:

source = "Name,Value\nfoo,0\nbar,1\nbaz,2\n"
table = CSV.parse(source, headers: true)
table.mode # => :col_or_row
table1 = table.by_row!
table.mode # => :row
table1.equal?(table) # => true # Returned self
