Comma-separated values (CSV) are a popular text format to interchange data. Gforth provides words for reading CSV files (with all features, including newlines in quoted strings).
read-csv ( addr u xt – ) gforth-experimental “read-csv”
Read CVS file addr u and execute xt for every field
found. Xt has the stack effect ( addr u field line
-- ), i.e. the field string (in de-quoted form), the current
field number (starting with 0), and the current line (starting
with 1).
csv-separator ( – c ) gforth-experimental “csv-separator”
CSV field separator (default is ‘,’, hence the name
"comma-separated"); this is a value and can be
changed with to csv-separator.
csv-quote ( – c ) gforth-experimental “csv-quote”
CSV quote character (default is ‘"’); this is a value and can be
changed with to csv-quote.
.quoted-csv ( c-addr u – ) gforth-experimental “dot-quoted-csv”
print a field in CSV format, i.e., with enough quotes that
read-csv will produce c-addr u when encountering the
output of .quoted-csv.
