(col-vecs->row-maps col-vecs)<TEMP> Converts a map of column-vectors into a sequence of row-maps

parse-csv->col-vecsclj
(parse-csv->col-vecs csv-input & {:as opts})[csv-input & {:as opts} ] Returns a map constructed from the columns of csv-input. The first line is assumed to be column label strings, which are (safely) converted into keywords. The returned map has one entry for each column label keyword. The corresponding value for each keyword is a vector of string data taken from each subsequent line in the file. See tupelo.csv/parse-csv->row-maps for options.
[csv-input & {:as opts} ]
Returns a map constructed from the columns of csv-input. The first line is
assumed to be column label strings, which are (safely) converted into keywords. The
returned map has one entry for each column label keyword. The corresponding value for
each keyword is a vector of string data taken from each subsequent line in the file.
See tupelo.csv/parse-csv->row-maps for options.parse-csv->row-mapsclj
(parse-csv->row-maps csv-input & {:as opts})[csv-input & {:as opts} ] Returns a lazy sequence of maps constructed from csv-input. The first line is assumed to be column label strings, which are (safely) converted into keywords. String data from each subsequent line is paired with the corresponding column keyword to construct a map for that line. Default delimiter is the comma character (i.e. ,) but may be changed using the syntax such as:
(parse-csv->row-maps <csv-data-src> :delimiter | )
to select the pipe character (i.e. |) as the delimiter.
[csv-input & {:as opts} ]
Returns a lazy sequence of maps constructed from csv-input. The first line
is assumed to be column label strings, which are (safely) converted into keywords.
String data from each subsequent line is paired with the corresponding column keyword to
construct a map for that line. Default delimiter is the comma character (i.e. \,) but
may be changed using the syntax such as:
(parse-csv->row-maps <csv-data-src> :delimiter \| )
to select the pipe character (i.e. \|) as the delimiter. row-maps->col-vecsclj
