• comby-refactoring.md: trying https://comby.dev/ as found by https://github.com/svetlyak40wt/comby-test

• shell-utils:tty-p: are we on a terminal window or on a dumb terminal (Emacs shell mode)?

• issr-test: testing http://cjackson.tk/todo-tutorial

• local-time.lisp: simple additions useful for me that won't be merged upstream.

• CSV parsing and manipulation with cl-csv and its companion data-table.

cl-csv "only" reads and parses the CSV. data-table allows to access all cells by row and column name (instead of by position).

;; Parse the CSV, get a data-table object.

(defun parse-csv (file)
  "Parse CSV, return a data-table object with column names and rows."
  (let ((rows (csv:read-csv (str:from-file file))))
    (make-instance 'data-table:data-table :column-names (first rows) :rows (rest rows))))

;; Iterate on rows,
;; access columns with data-table-value :row row :col-name "the col name"

(defun get-all-days (dt)
  (remove-duplicates
   (loop for row in (data-table:rows dt)
         collect (data-table:data-table-value dt :row row :col-name "Date"))
   :test #'equal))

redditors also mentioned that cl-duckdb is useful and pretty fast at parsing.
