- csv(?Rows)// is det
- csv(?Rows, +Options)// is det
- Prolog DCG to `read/write' CSV data. Options:
- separator(+Code)
- The comma-separator. Must be a character code. Default is
(of course) the comma. Character codes can be specified
using the 0' notation. E.g., using
separator(0';) parses
a semicolon separated file.
- ignore_quotes(+Boolean)
- If
true (default false), threat double quotes as a normal
character.
- strip(+Boolean)
- If
true (default false), strip leading and trailing
blank space. RFC4180 says that blank space is part of the
data.
- skip_header(+CommentLead)
- Skip leading lines that start with CommentLead. There is
no standard for comments in CSV files, but some CSV files
have a header where each line starts with
#. After
skipping comment lines this option causes csv//2 to skip empty
lines. Note that an empty line may not contain white space
characters (space or tab) as these may provide valid data.
- convert(+Boolean)
- If
true (default), use name/2 on the field data. This
translates the field into a number if possible.
- case(+Action)
- If
down, downcase atomic values. If up, upcase them
and if preserve (default), do not change the case.
- functor(+Atom)
- Functor to use for creating row terms. Default is
row.
- arity(?Arity)
- Number of fields in each row. This predicate raises
a
domain_error(row_arity(Expected), Found) if a row is
found with different arity.
- match_arity(+Boolean)
- If
false (default true), do not reject CSV files where
lines provide a varying number of fields (columns). This
can be a work-around to use some incorrect CSV files.
