_[Function]_
**csv-parse-error** ( *msg `&rest` args* ) =\> \*result*
- - -
_[Macro]_
**do-csv** *((row-var stream-or-pathname `&rest` read-csv-keys)
`&body` body)* =\> \*result*
row-var: a variable that is passed into _body_
stream-or-pathname: a stream or a pathname to read the CSV data from
read-csv-keys: keys and values passed to the _read-csv_ function
body: body of the macro
- - -
_[Generic function]_
**format-csv-value** ( *val* ) =\> \*result*
- - -
_[Method]_
**format-csv-value** ( *val* ) =\> \*result*
Print values in ways that are most cross compatible with the csv
format
- - -
_[Function]_
**read-csv** ( *stream-or-string* `&key` *row-fn* *map-fn* *sample*
*skip-first-p* ( separator \*separator\* ) (quote \*quote\*) (escape
\*quote-escape\*))* =\> \*result*
Read in a CSV by data-row (which due to quoted newlines may be more
than one line from the stream)
row-fn: passing this parameter will cause this read to be streaming
and results will be discarded after the row-fn is called with data
map-fn: used for manipulating the data by row during collection if
specified; (funcall map-fn data) is collected instead of data
sample: when a positive integer, only take that many samples from
the input file
skip-first-p: when true, skips the first line in the csv
