[GUI Plugin] Count Pages

[theducks]

CP does not use the DEVICE config screen (the top)

You need to set up Custom columns of the correct type, the configure CP to use those (the names are only suggested)

But in the end, I stll think the Kindle will do its own thing when transfered (the CP columns are for YOU to see in Calibre).

@J-Wo: Sorry, I can't help here. My Kindle knowledge is very low. I know the driver can do something with the page count, but, I don't know what. Also, you haven't actually told us what the problem is. I assume it is that the page count calculated by the Count Pages plugin are not appearing on your Kindle, but, that's really just a guess. If that is the case, and there is a value in the #pages column when you send the book to the device, then it isn't a problem with this plugin.

And that last statement reminds me to ask the obvious question: Are you running Count Pages for the books before sending them to the device?

Becky: Sorry, I completely forgot about this over the weekend.

Everyone: I promise I'll release it this week or next weekend. If you don't see anything by the weekend, nag me a little so I don't forget.

Yes you're right sorry I wasn't clear. After transferring a MOBI or AZW3 file to my Kindle Paperwhite, I still only see Loc, Mins left in chapter, and Mins left in book. I don't see any page numbers on my books.

I am running Count Pages for the books, and they do show up in my custom Pages column on Calibre. Before sending the book to my device, do I have to reconvert it again? If the book is already on my device, do I just need to resend the metadata?

What do you mean by "CP does not use the DEVICE config screen (the top)". What is (the top)?

Here is how I've configured my device in Calibre:

• Type the name of your custom column in the textbox as shown in the attached screenshot 6 below.

I already posted my problems in the Kindle forum, and they suggested I come here instead. Now it looks like there are no Kindle owners in this plugin thread? I'm really confused!

From what I can tell, you are using the Count Pages plugin correctly. And you have the Kindle driver configured correctly. Sending the book to the device should be enough. But, I don't know what the Kindle driver and device does with it. And that's a question for the driver maintainer or others who use this function in the driver. Unless someone who uses this plugin and sends the counts to a Kindle sees this, I would suggest starting a new thread and asking. I do vaguely remember discussion on this, so a search might find the answer.

I did notice that my Kindle does not have any .APNX files on it. Isn't that where the page numbers are stored and should be sent to my device by Calibre?

I've also been playing around with the device interface plugin settings, so maybe I screwed something else there. Also there appear to be two Kindle device plugins, so I don't know if one is conflicting with the other?

IIRC page numbers are only supported when you send books to e-ink based kindles using the USB connection. Although I dont use that function, so I could be wrong.

That's what I'm doing on my PW3

[kovidgoyal]

Then run calibre debug mode and look at the log after sending a book, it will likely contain an error message indicating failure reading the page counts or sending the apnx file.

I cant be sure since you've redacted the title and author, but most likely the full path to the apnx file is too long for windows/the fat32 filesystem on the kindle. You can change your sned to device template to shorten the path by right clicking the device icon in calibre and choosing Configure this device.

[J-Wo]

Yes you are absolutely right. I recently installed the Goodreads metadata plugin and it updated my book with a very long title. So after renaming the title to something shorter, I now get page numbers on my Kindle! Thanks for the help @ kovidgoyal

Even if you don't speak German you should be able to follow the code and the screenshots.

The real fun started when I wanted to convert the floating point number into a string with hour and minute (e.g. 6.7 -> 6:42h). The template functions are very limited so I came up with some ugly code to do the job.

Thanks for the link! Could you post the code you used to convert into hours and minutes?

[red_dragon]

Beware, this is kind of ugly because Calibre doesn't provide math functions (especially modulo) that would make life so much easier.

program:

# This program calculate a reading time per hour for a ebook

# Adjustments:
# w_min -> minimum words per minute
# w_max -> maximum words per minute
w_min=250; 
w_max=450;

# readingtime per hour=60
p_time=60;

# Needs a custom column for word count (#words)
# change it to your field name
words=raw_field('#words');

time1=format_number(divide(words,multiply(w_max, p_time)), '{0:.2f}');
time2=format_number(divide(words,multiply(w_min, p_time)), '{0:.2f}');

# Unfortunately Calibre doesn't provide a simple way to convert a float
# into a time string so I do it the really REALLY hard way.

# get the hour BUT take into consideration that Python rounds 
# the numbers automatically!
# Subtracting 0.49 should always yield the correct value 
# (e.g. 9.0 -> 8.51 -> rounded up to 9)
# To the minutes I add a leading '0' for easier conversion later,
# otherwise times are displayed as 4:4h instead of 4:04h.
rt1_hour=format_number(subtract(time1, 0.49), '{0:.0f}');
rt1_minute=format_number(multiply(subtract(time1,rt1_hour),60), '0{0:.0f}');

rt2_hour=format_number(subtract(time2, 0.49), '{0:.0f}');
rt2_minute=format_number(multiply(subtract(time2,rt2_hour),60), '0{0:.0f}');


# It can also happen that the hour value is -0 (!) if the 
# reading time is < 30min.
rt1_hour = re(rt1_hour, '-', '');
rt2_hour = re(rt2_hour, '-', '');

# only the last 2 chars are needed from the minutes.
readingtime=strcat(rt1_hour,':', substr(rt1_minute, -2, 0), 'h - ', rt2_hour, ':', substr(rt2_minute,-2,0), 'h');

Thank you! I couldn't get it to work...
I just changed 0.49 with 0.499 because I had two books that gave me reading times of X hours and -1 minutes (the reading time in hours was something like 3.9917).

Edit: and after having looked at it a little more, I hadn't though to use regex, but we could also simply do rt1_hour=re(time1, '\.\d*', ''); to truncate the hour... This way no rounding occurs

So here is what I got:

Spoiler:

program:

# This program calculate a reading time per hour for an ebook

# Adjustments:
# w_min -> minimum words per minute
# w_max -> maximum words per minute
w_min=250; 
w_max=300;

# readingtime per hour=60
p_time=60;

# Needs a custom column for word count (#words)
# change it to your field name
words=raw_field('#words');

time1=format_number(divide(words,multiply(w_max, p_time)), '{0:.2f}');
time2=format_number(divide(words,multiply(w_min, p_time)), '{0:.2f}');

# Unfortunately Calibre doesn't provide a simple way to convert a float
# into a time string -> I used a regex
# The minutes can be set to use 2 numbers using python number formatting,
# otherwise times are displayed as 4:4h instead of 4:04h.
rt1_hour=re(time1, '\.\d*', '');
rt1_minute=format_number(multiply(subtract(time1,rt1_hour),60), '{0:02.0f}');

rt2_hour=re(time2, '\.\d*', '');
rt2_minute=format_number(multiply(subtract(time2,rt2_hour),60), '{0:02.0f}');

readingtime=strcat(rt1_hour,':', rt1_minute, 'h - ', rt2_hour, ':', rt2_minute, 'h');

Thanks again for sharing
