Migrating my IMDb ratings list and watch list into org-mode


Table of Contents

Preamble

I have been using org-mode to keep track of my movie ratings and critiques. Org-mode, combined with org-ql, gives me quite a lot flexibility. I'm also utilizing Zettelkasten-like backlinking and references, so keeping these rating information on org-mode makes sense for me. First, let me show you how it looks like:

And this is how a movie with it's properties looks like:

org_imdb_expanded.png

I mainly automated the needed information-retrieval using the orgmdb.el, a package that I wrote. The link contains the related information for automatically filling this data. Before all that, I was using IMDb to log my ratings only. So I just wanted to migrate those ratings into my new org-mode based watch/rating list.

Exporting the data from IMDb

Log in to IMDb and open this link. Hit the 3-dot icon on top-right and click Export.

This will give you a file named ratings.csv.

Parsing the data

I just searched for elisp csv and used the first package that came across. I did not want to split lines with "," because there are some quoted texts in the csv and that might contain commas itself. Using a library that handles these cases are just better.

(use-package parse-csv
  :ensure t)

With the following we can parse the data into '((movie1 properties ...) (movie2 properties ...)):

(setq
 my-movie-data
 (parse-csv-string-rows
  (with-temp-buffer
    (insert-file-contents "~/Downloads/ratings.csv")
    (buffer-string))
  ?\, ?\" "\n"))

Generating the org-mode rating list

I like using dash.el functionality for these kind of one-off scripts, it's very convenient and easy to write. With the following, we can convert the data in the ratings.csv into our custom org mode format.

(->> my-movie-data
  ;; Skip the CSV header
  (-drop 1)
  ;; Skip empty lines etc.
  (--filter (cdr it))
  ;; Format all movies into the format I use in my watchlist
  (--map (format
          "** DONE %s (%s) :%s:\n:PROPERTIES:\n:GENRE:    %s\n:RUNTIME:  %s\n:DIRECTOR: %s\n:RATING:   %s\n:WATCHED:  %s\n:IMDB-ID:  %s\n:END:"
          (nth 3 it)
          (nth 8 it)
          (nth 5 it)
          (nth 9 it)
          (format "%s mins" (nth 7 it))
          (nth 12 it)
          (nth 1 it)
          (format "[%s]" (nth 2  it))
          (nth 0 it)))
  ;; Reduce everything into one single string
  (--reduce (format "%s\n%s" acc it))
  ;; Copy the string
  (kill-new))

This will format all movies into the format I just showed you above and copy the resulting string into your clipboard, so that you can paste it into your watch list file. Feel free to change the formatting to your liking.

Appendix: Getting the movie country data

I was not satisfied with the above result, because I also like to have a :COUNTRY: field in movies property list so that I can filter based on country etc. As ratings.csv does not provide this information, I had to use the orgmdb package I mentioned earlier.

First, I needed to format the data in the ratings.csv into something like this:

(setq
 isamert/movie-rating-list
 '(("tt1010048" . (7 2016-08-30))
   ("tt0101540" . (6 2017-03-13))
   ("tt1019452" . (8 2019-11-29))
   ...))

…using this command and then doing a bit of manual work:

cat ratings.csv | awk -F, '{print "(\"" $1 "\" . (" $2, "\""$3 "\"))"}'

Because I only need the rating I gave to the movie and the date I gave it from the file, I'll get the rest using orgmdb:

(setq isamert/movies
      (--map
       (orgmdb :imdb (symbol-name (car it)))
       isamert/movie-rating-list))

This may take a few minutes depending on how much movies you have in your list. I had to wait couple of minutes for ~500 movies. Now that we have all information we need, we can generate our custom org rating list:

(->> isamert/movies
  (--map (let* ((info (cdr (assoc-string (alist-get 'imdbID it) isamert/movie-rating-list))))
           `(,@it (MyRating . ,(car info)) (MyRatingDate . ,(cdr info)))))
  (--map (format "** DONE %s (%s) :%s:\n:PROPERTIES:\n:GENRE:    %s\n:RUNTIME:  %s\n:DIRECTOR: %s\n:COUNTRY:  %s\n:RATING:   %s\n:WATCHED:  %s\n:IMDB-ID:  %s\n:END:"
                 (alist-get 'Title it)
                 (alist-get 'Year it)
                 (alist-get 'Type it)
                 (alist-get 'Genre it)
                 (alist-get 'Runtime it)
                 (alist-get 'Director it)
                 (alist-get 'Country it)
                 (alist-get 'MyRating it)
                 (format "[%s]" (alist-get 'MyRatingDate it))
                 (alist-get 'imdbID it)))
  (--reduce (format "%s\n%s" acc it))
  (kill-new))

Nice.
