text.csv- CSV tables
Provides a function to parse/generate CSV (comma separated value) tables, including the format defined in RFC4180. You can customize the separator and quoter character to deal with variations of CSV formats.
CSV table is consisted by a series of records, separated by a newline. Each record contains number of fields, separated by a separator character (by default, a comma). A field can contain comma or newline if quoted, i.e. surrounded by double-quote characters. To include double-quote character in a quoted field, use two consecutive double-quote character. Usually, the whitespaces around the field are ignored.
Right now, the following two low-level procedures are exported. A plan is to provide higher features, such as labelling fields and automatic conversions.
Returns a procedure with one optional argument, an input port. When the procedure is called, it reads one record from the port (or, if omitted, from the current input port) and returns a list of fields. If input reaches EOF, it returns EOF.
Returns a procedure with two arguments, output port and
a list of fields. When the procedure is called, it
outputs a separator-separated fields with proper escapes,
to the output port. You can also specify the record delimiter
string by newline; for example, you can pass
to prepare a file to be read by Windows programs.
