This library aims to simplify working with csvs to the bare minimum of tedium
I had many scattered, not well tested, not easily runable pieces of csv code. I was unhappy with this situation then decided to refactor all of this into a single location. I wrote tests for it and had a library so I thought I might release it. This project started as extensions and bugfixes on arnesi's CSV.
I then looked around and saw there are other csv libs out there that probably mostly accomplished what I had set out to do. However, I already had code that was tested and had an easier license (BSD) so, I figured why not just release it anyway.
There are two modes for escaping currently
* :quote - by default cl-csv treats ""
as an escape for a single double-quote
* :following - read the character after the escape sequence verbatim, commonly
the *quote-escape*
will be set to #\\
when the escape mode is following.
*enable-signals*
will cause a csv-data-read or csv-row-read to be
signaled for each piece of data and row read. There is a filter
restart available which will cause the filter value to be used
instead. Enabling signals is ~2xs as slow as not, so by default
they are not enabled.in-csv

in-csv
driver clause for iterating over a CSV;; read a file into a list of lists
(cl-csv:read-csv #P"file.csv")
=> (("1" "2" "3") ("4" "5" "6"))
;; read a file that's tab delimited
(cl-csv:read-csv #P"file.tab" :separator #\Tab)
;; read a file and return a list of objects created from each row
(cl-csv:read-csv #P"file.csv"
:map-fn #'(lambda (row)
(make-instance 'object
:foo (nth 0 row)
:baz (nth 2 row))))
;; read csv from a string (streams also supported)
(cl-csv:read-csv "1,2,3
4,5,6")
=> (("1" "2" "3") ("4" "5" "6"))
;; loop over a CSV for effect
(let ((sum 0))
(cl-csv:do-csv (row #P"file.csv")
(incf sum (parse-integer (nth 0 row))))
sum)
;; loop over a CSV using iterate
(iter (for (foo bar baz) in-csv #P"file.csv")
(collect (make-instance 'object :foo foo :baz baz)))
