Reading

Reading is a Ruby gem that parses a CSV reading log. My personal site's Reading List and Reading Statistics pages are built with the help of this gem.

Because I love reading, and keeping a plain-text reading log helps me remember, reflect on, and plan my reading (and listening, and watching).

My CSV reading log serves the same role as Goodreads used to, but it lets me do a few things that Goodreads doesn't:

• Own my data.
• Add items of any format: podcasts, documentaries, etc.
• Edit and search in a plain text file, which I prefer over navigating a site or app. I can even pull up my reading log on my phone via a Dropbox-syncing text editor app—Simple Text is the one I use.

This gem solves the biggest problem I had with a plain-text reading log: how to share my favorite reads with friends? The gem's parser transforms my reading.csv into data that I can selectively display on my Reading List page.

The Reading gem also gives statistics data, exemplified on my Reading Statistics page.

Add this line to your application's Gemfile:

gem 'reading'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install reading

CSV Format Guide on how to set up your own CSV reading log.

Parsed Output Guide on the structure into which the Reading gem parses CSV rows.

test/parse_test.rb has more examples of the CSV format.

For examples of real-life usage, see the LoadReadingList plugin on my website, which gets my reading.csv from Dropbox and parses it. The parsed items are used on two pages:

• fpsvogel.com/reading: source plus view component source.
• fpsvogel.com/reading-stats: source.

To quickly see the parsed output from a CSV string, use the reading command:

$ reading '3|📕Trying|Little Library 1970147288'

See the CSV Format Guide for more on columns, but here suffice it to note that this CSV string has the first three columns (Rating, Head, and Sources).

An optional second argument specifies enabled columns. The CSV string above already omits several right-side columns, but to omit a left-side or middle column we'll have to disable it. For example, to omit the Rating column from the example above:

$ reading '📕Trying|Little Library 1970147288' 'head, sources'

The reading command can also start a prompt to query for reading statistics. For more on that, see "Get statistics on your reading" below.

To parse a CSV reading log in Ruby rather than on the command line:

require 'reading'

file_path = "/home/user/reading.csv"
items = Reading.parse(path: file_path)

This returns an array of Items, which are essentially a wrapper with the same structure as the template Hash in Config#default_config[:item][:template] in config.rb, but providing a few conveniences such as dot access (item.notes instead of item[:notes]).

If instead of a file path you want to directly parse a String (or anything else responding to #each_line, such as a File):

require 'reading'

csv_string = '3|📕Trying|Little Library 1970147288'
items = Reading.parse(lines: csv_string)

To use custom configuration, pass a config Hash when initializing.

Here's an example. If you don't want to use all the columns (as in the minimal example in the CSV format guide), you'll need to pass in a config including only the desired columns, like this:

require 'reading'

custom_config = { enabled_columns: [:head, :end_dates] }
file_path = "/home/user/reading.csv"
items = Reading.parse(path: file_path, config: custom_config)

Once you've parsed your reading log, you can easily filter the output like this:

# ...
# (Already parsed a reading log into `items` as above.)
filtered_items = Reading.filter(
  items: items,
  minimum_rating: 4,
  status: [:done, :in_progress],
  excluded_genres: ["cats", "memoir"],
)

The reading command can also start an interactive statistics-querying mode if the command is given the path to a CSV file:

$ reading /home/user/reading.csv

Then a prompt will appear, in which you can type commands made up of an operation optionally followed by one or more groupings and/or one or more filters.

Here are a few examples:

average rating
total amount by month
total items by year, genre
top 5 lengths status!=planned format=print, ebook
top 3 amounts by year rating>1 done<100% source~library

Warning The operation, grouping, and filter(s) must appear in that order, or else the query may yield unexpected results.

You can also get statistics via Ruby code rather than on the command line:

# ...
# (Already parsed a reading log into `items` as above.)
results = Reading.stats(
  input: "total amount by month"
  items: items,
)

The last word may be pluralized.

• average rating
• average length
• average amount
• average daily-amount
• list items (or just list)
• total items (or just items, or count)
• total amount (or just amount)
• top/bottom [N] ratings
• top/bottom [N] lengths
• top/bottom [N] amounts
• top/bottom [N] speeds
• debug to view the results in a Ruby debugger

These too may be pluralized.

• by month
• by year
• by genre
• by rating
• by format
• by source
• by length

These may be pluralized, and may be followed by any of the operators listed for each. The operators ~ and !~ mean "contains" and "does not contain", respectively.

• genre (=, !=)
• rating (=, >, >=, <, <=, !=)
• format (=, !=)
• source (=, !=, ~, !~)
• title (=, !=, ~, !~)
• author (=, !=, ~, !~)
• series =, !=, ~, `!~
• note (=, !=, ~, !~)
• status (=, !=)
• length (=, >, >=, <, <=, !=)
• done (=, >, >=, <, <=, !=)
• experiences (i.e. number of reads) (=, >, >=, <, <=, !=)
• date (=, >, >=, <, <=, !=)
• end-date (=, >, >=, <, <=, !=)

After Reading parses your CSV reading log, it's up to you to display that parsed information on a web page. I've set up my personal site so that it parses my reading log during site generation, and it's even automatically generated every week. That means my site's "Reading" page automatically syncs to my reading log on a weekly basis.

I explain how I did this in my tutorial "Build a blog with Bridgetown", which may give you ideas even if you don't use Bridgetown to build your site… but you should use Bridgetown, it's great 😉
