[Metadata Source Plugin] Romance.io

This plugin adds Romance.io as a metadata source in Calibre. Romance.io is a community site for romance novels with detailed reader tags (tropes, themes, settings, etc.), steam ratings, and user star ratings.

When you download metadata for a book, Calibre will search Romance.io, and if there is a match, the plugin:
  • Finds the Romance.io book ID and shows a link to the book's Romance.io page in the book details panel
  • Offers Romance.io cover art as a download option alongside other sources
  • Fills in series, series number, and publication date metadata from Romance.io
  • Maps Romance.io genre tags (e.g. time travel, enemies to lovers, small town, nerdy hero) to Calibre tags via a configurable table

The stored romanceio identifier is also used by the companion Romance.io Fields plugin to fetch ratings and tags into custom columns.

For more detailed instructions, see the plugin's GitHub.

Installation:
In Calibre: Preferences > Plugins > Get new plugins, search for "Romance.io", and click Install. Or download the zip from GitHub and install via Preferences > Plugins > Load plugin from file.

Usage:
  1. After installing, go to Preferences > Metadata download and check the box next to Romance.io to enable it as a source.
  2. Select a book in your library, click Edit metadata, then click Download metadata. If a match is found on Romance.io, you'll see "See at: Romance.io" in the results. Click OK to link your Calibre library book with the book found on Romance.io and download metadata.

Configuration:
Preferences > Metadata download > Romance.io > Configure selected source
  • Metadata fields to download - choose which fields to pull (cover, series, tags, date, etc.)
  • Tag mappings - map Romance.io tags to Calibre tags. Only mapped tags are imported.

Wrong book matched? If your title or author in Calibre differs from Romance.io (different edition name, spelling, etc.), the automatic search may not work. You can still manually link the book: open the book's detail page on Romance.io (URL contains /books/, not the series page), copy the ID from the URL (e.g. 5484ecd47a5936fb0405756c), then in Calibre open Edit metadata > Ids and add romanceio:5484ecd47a5936fb0405756c.

Notes:
  • The plugin tries the Romance.io JSON API first (fast, no browser). If the API returns no result, it falls back to loading the page in the browser. If a browser window opens, ignore it - it will close automatically.
  • Only English is supported for now.

I have tried using this and successfully brought the tags into a field, but when you map them via preferences>metadata download>romance.io plugin ot doesn't do anything. It seems to be because it pulls through fields as a continuous single option instead of a list of tags. It only shows as a single 'tag' even when there's 20+ tropes from romance.io

Thank you for trying out the plugin! I can't seem to replicate your issue. From my machine, I can go through the steps in the screenshots below and get the tag mapping working for multiple fields. We must be doing something differently!

I did find a setting that might be related and I just updated the plugin to 1.0.3 in case that addresses your issue (it should be available in Calibre shortly), as well as making the Readme more clear. Can you try it out and, if it's still not working, give me some additional info:
  • If you are doing any steps differently than I am in the attached screenshots, or if not, where your results are different from mine
  • The Romance.io link to the book you're using
  • The exact values for "Romance.io Genre" and "Maps to Calibre Tag" that aren't working
  • What result you're getting vs. what result you expected

With that info I should be able to figure out what's going wrong!

So....was it supposed to create an over 225GB folder recreating every instance of Chrome User data for every download?

I feel bad for the people who thought to just let this thing run on overnight so they can get all the tags....

I have a 1 TB SSD that has never been more than 60% full. Between this and another program that initially downloaded every audiobook I own (over 400 books) to my C drive when I pointed it elsewhere - I maxed out the drive - wiped the shadow copies and incurred another 88GB pagefilesys that needs to be fixed.

I have been trying to delete this folder for over an hour - it still has 130GB to go.

Just thought you all should know.

I'm so sorry about that! I've been using the plugin for a few months myself and never ran into this because the JSON API used to work fine and Chrome was rarely needed. Since it went down about a week ago, the plugin has been relying on Chrome much more heavily, and you would definitely notice this if you're backfilling an entire library.

Luckily it was an easy fix. I've just updated the plugin (v1.0.6) so that the profile folders are now created in your system's TEMP directory and deleted immediately after Chrome closes. Even if Chrome crashes, the cleanup will still run. The plugin will also delete any leftover profile folders from the old location the next time it runs.

If you've already accumulated a lot of folders you could either:

1. Let the new version of the plugin (v1.0.6) clean up for you - just run it again after updating and it will delete the old folders automatically. If you have a lot of data built up, the first fetch may take a while to clean up before starting.

2. Delete the user_data folder manually to get the space back immediately. You can delete the entire user_data subfolder safely, since it's not related to your personal Chrome profile. The drivers and downloads subfolders next to it are fine to keep - those have the chromedriver binary and avoid re-downloading it every time. It's located here:

Windows: C:\Users\<your username>\.calibre_selenium\user_data\
Mac/Linux: ~/.calibre_selenium/user_data/

Thank you for noticing this and sorry again for filling up your computer

I might be mixing this up with the other romance.io plugin, but i am having issues with both I think.

Looking first at the fields issue - my problem here is that the metadata download doesn't find anything from romance.io, even when ive made the same amendments to the configuration that you show in your screenshots. I've purposefully tried it on popular books that i know exist on romance.io, but i get nothing but the other sources - it says its checking romance.io but never ever finds metadata from it.

Is there anyway i can get data to find out why this would be? Does it need the latest update of Calibre itself?

I've attached where I have set everything up for the metadata download

I downloaded the latest version from GitHub and unchecked my other metadata plugins. Testing on a couple of my spouse's book, I got a few tags, the series and index and a low res cover image. I did notice that Chrome popped up to fetch the page. The lack of a summary is pretty much a don't bother with this plugin for me since I normally leave the Tags unchecked in the metadata fields to download. My spouse wants the summary so again, making this plugin a non-starter.

I don't see an attachment - could you share the log output you're seeing in the plugin? That would help me figure out what's going wrong!

This is super helpful feedback, thank you! I'll take a stab at adding the summary for the next release. Hopefully it's not too complicated!
