[nondet]csv_read_file_row(+File,
-Row, +Options)True when Row is a row in File. First unifies Row
with the first row in File. Backtracking yields the second,
... row. This interface is an alternative to csv_read_file/3
that avoids loading all rows in memory. Note that this interface does
not guarantee that all rows in File have the same arity.
In addition to the options of csv_read_file/3,
this predicate processes the option:
- line(-Line)
- Line is unified with the 1-based line-number from which Row
is read. Note that Line is not the physical line, but rather
the
logical record number.
- To be done
- Input is read line by line. If a record separator is embedded in a
quoted field, parsing the record fails and another line is added to the
input. This does not nicely deal with other reasons why parsing the row
may fail.
