[GUI Plugin] Count Pages

1. Count the unique words in an e-book.
2. Count how many unique words are different between certain e-book combinations.

These ideas help language learning with the following.
First, I know I will not meet a lot of unknown words in my next book. Second, I know I will not spend too much time studying a book with only a few new unknown words or, in contrast, too many, making the reading of an e-book painful.

Right now, I do these with the help of ebook-convert and bash scripts but it'd be nice to see them in calibre.
Is there a git page for this plugin? I'm new to the calibre ecosystem hence the question.

Neither of those are things that I am interested in doing. If you want to do the first one, then I'm happy to answer any questions about the plugin.

But, I'm not sure the second fits with this plugin. The plugin only acts on one book and does the calculations and stores them. And strictly, once done, it won't be needed to be done again. For the comparison, you would need to select multiple books and the calculation. Then choose different books and do them again. And where would the results be stored?

There are some other plugins that might help. There is the "English Noun Frequency" plugin which does various things related to English nouns. And "Similar Books" that does some comparison to show if a book is similar to another. It hasn't been updated for a while, so might not work.

There is no Git or similar repository for the plugin. The code is completely within the plugin. If you want to make changes and discuss them, you can do it here. Same if you want to post a beta.

@costis - if you have a book in an editable format (EPUB, AZW3) the Reports option in calibre's Book Editor can provide a list of unique words, and counts, which can be saved to a file. You could use a diff tool to compare word lists from different books.

The one thing it lacks is a case insensitive option - hint, hint Kovid

Hi to all,
I installed on my Calibre from pc the plugin "Count page", but I see that the book appear as usual and doesn't compare any page number. Can you explain me how does it work?

Thanks

[theducks]

Did you create any custom columns?
Then did you configure the plugin to use the new columns?
(and optionally, what method to use to count/download the page count)

Did you read the first post in the Count Pages plugin thread? See Index of plugins

Yes. But, the plugin has to be configured, then you need to run it for each book you want the page count for. The page count can come from the book (calculated in different ways) or retrieved from a web site. Once this is done, the page count will be displayed.

Beyond that, the information is in the first post of the thread. Rewriting that is unlikely to help, as it would be written in English and take a reasonable amount of time. But, if you have tried to follow those instructions and don't understand something, ask and we can try and explain it.

Ok, thank you for explaining. I will try to find out how to do.

Hi,
I'm recieving this error:
The Rising of the Shield Hero Vol 01 (No identifiers for selected download sources)

How can solve it? I tried with multiple books but it doesn't work

[shamanNS]

"No identifiers for selected download sources.". The problem is clear: you configured Count Pages plugin to download page count (instead of generating by analysing the book file) from one of the supported source websites (like Goodreads) but you didn't add to book metadata the ID (identifier) from that website before trying to get page count.

In case of Goodreads the ID can be populated by using either Goodreads Metadata plugin or by using Goodreads Sync plugin. Or manually by copy/paste from Goodreads website into Calibre's Edit metadata window.

[theducks]

That simply says, the Metadata sources you have configured, do not have identifiers.
1) possibly enable / install sources that have that title
2) If there is an entry in the MDE: Identifiers, remove those (broadens the search scope) Do the Get Metadata from the MDE so you can cherry pick the best results

Thanks for the help, so in order to get the page count I should add the goodreads plugin too!
I tried to use the "estimate page" function but it only counts 7 pages out of hundreds.

Here's the log:

For some reason even if counts 367 pages in the page columns it display 7.

Just to be sure I deleted and recreated the pages columns just like the istruction said.
Also other bug: after disabling Gunning fog, the first count will save the number of words. Running the plugin again will correctly save the number of pages.

Apparently the plugin is not taking the right number when saving it. The version is 1.11.2

You probably have the column for the pages incorrectly configured. Check that it is an integer and that the formatting makes sense. And you can check the actual value using the metadata editor/

I created the pages column by copy pasting the first post. It's integer and the formatting is {0:,d}.
In the metadata editor the value is "correct" (64000pages), if I run twice it works properly.

Tried to uninstall and reinstall, same behavoir: first run-> save words count, second run ->save pages, third run -> save words, etc. in a loop.

I missed that statement in the first post. Check what you have set as the column to be used for each of the stats. That behaviour sounds like you have the same column used for both the word and page count. And possibly the other stats. That means the value of the column will be set to whichever of the stats was updated to the metadata last. You need to use different columns for each stat you want to calculate.
