Plugboard, template, and custom composite column recipes

[assur191]

I just purchased a Kindle, and I wish to have the title of each book include not only the series name, but also the over-arching meta series name and index, if available. For example:

The book "Rogue Squadron" is book one of the series "X-Wing", which is itself a part of the meta-series "Star Wars". I would like the title to appear as "Star Wars: X-Wing - 01 - Rogue Squadron". I have created a custom field in Calibre titled "Meta Series" which holds the data "Star Wars". I'd want to be sure that the colon or dash marks don't appear if there is nothing in the fields.

How would I go about setting up a pegboard for this? Any help is appreciated.

Thank you.

Hi All
The following HOWTO was developped in another thread.

Chaley suggested to put it here as well.

Do you have a Kindle ?
Did you ever want Calibre to show "Read Status" of your books in a column ?
Automagically ?

Then the following might for you as well.

You must be running Calibre 0.7.40 or newer to use this.
Also you must use "Fetch annotations" from you Kindle.

The following example is based on the following Kindler requirements:
"What I want is a custom column to show the "Last Opened" Date if Last location read > 95%.
If the book shows >0% but < 95%, I want the column to show "Reading"
And if the book is 0%, or unopened, the column should show "Not Read".


Howto "Fetch annotations" from you Kindle:
Start Calibre,
Connect your Kindle, wait a bit,
Click on the arrow just to the right of the "Send to Device" icon,
choose "Fetch Annotations"
and the Kindle "Book status" is added to the Calibre book details, in the comments.

You should Fetch fresh Annotations everytime you connect your Kindle to get updated information.

This is just an example of what I could get with my K3:

25-12-2010
Last Page Read: Location 7365 (68%)
Location 4603 • Bookmark
Location 4942 • Bookmark
Location 4980 • Bookmark
Location 5984 • Bookmark
Location 7363 • Bookmark


The best/fastest way, but hardest way, to get the needed information into a custom column, is to use Python Template functions.
Sounds scary, but don't worry. Copy/paste is your helper

Simply do as follows:

1) go to Preferences -> Advanced -> Template Functions.

2) in the Function box type: kindle_read_status

3) in the Arg count box type: 4

4) in the Documentation box, paste the following:

Check if the associated field contains a kindle annotation for percent read. 
If not, return no_page_read_str. 
If annotations are found, then compare that percent against is_read_pct. 
If the val is larger, then return date, 
if the val is >0 and < is_read_pct return is_reading_str. 
Otherwise return is_not_read_str. 

One usage: {comments:kindle_read_status(95,Not Read,Reading)}
( use the above when defining your custom column )

95 goes into variable is_read_pct
Not Read goes into variable no_page_read_str
Reading goes into variable is_reading_str

Feel free to change the %, the test strings to suit your needs.
Do this in the custom column definition.

5) In the Program Code box, paste the following:

def evaluate(self, formatter, kwargs, mi, locals, val, is_read_pct,  
				is_reading_str, no_page_read_str):
	try:
		test_val = int(is_read_pct)
	except:
		return 'is_read_pct is not a number'

	import re
	mg = re.match('.*\s(\d+[-/]\d+[-/]\d+).*?Last Page Read: Location \d+ \((\d+)%\)', val, re.I + re.DOTALL);
	if mg is None:
		return no_page_read_str
	date = mg.group(1)
	pct = mg.group(2)
	try:
		f = int(pct)
		if f > test_val:
			return date
		elif f > 0:
			return is_reading_str + ': ' + pct + '%'
	except:
		pass
	return no_page_read_str

6) press the Create button, then the Apply button.

7) Still in Preferences, Choose Add your own columns

8) Choose Add custom column bar at the bottom

9) enter the following into your custom column:
Lookup name: read_status
Column Heading: Read Status
Column type: Column built from other columns
Template:

{comments:kindle_read_status(95,Reading,Not Read)}

10) Choose Apply

11) Click Ok to the Restart Warning

12) Shutdown Calibre

13) Start Calibre

If you followed instructions minutely, you should have a new column showing the "Read Status" for your books.

He has been absolutely fantastic and helpfull with this.

If this fails, please try one more time before posting to this thread.
This has been tested by several Kindlers succesfully.

Enjoy

Note: If you want a text returned instead of a date when a book is read

Very interesting, one question though: Why does this new column not show up in the columns section on the left? Now I have to go "read" books I have already read so that they are all registering correctly. Thank you all for this one.

Maybe calibre has to be restarted for this to show there.

No, a restart does not produce it either, but no big deal.

One more question: Is there a way to adjust the template to pull the annotations from K4PC, since that is easier to use to go back to adjust the locations for the books?

Nevermind, I can just manually copy them from the k4pc directory to the kindle.

Me again, I am having a little trouble with where the data is being inputted from the annotation. This is what the format is:

1/24/2011
Last Page Read: Location 721 (99%)

But with that data it is adding a + to the tags field and 1/24/2011 to the read-status field. How do I get it to not add anything to the tags field and to add the read status with the percentage to the read_status field?

Hi
I can confirm that something is going on with the tags, adding a +
Don't use/show tags myself, so this I missed.
Will try to find out what/why, but still new to this.

The example will only return one value. The example wanted to use 95% as the comparison value.
Try changing you costum column definition to

{comments:kindle_read_status(99,Reading,Not Read)}

I don't know why a + is being added as a tag, but when creating a catalog in calibre I believe every book that has a + as a tag is treated as read.

Hi dwanthny
Yep - did a lot of Googling, to confirm this.
I'm sure that the + is added by "Fetch Annotations", no matter which custom columns you might have had.
I would guess the idea was to Mark a book "read" by adding the + to the tags. This was way before custom columns etc.
Not sure what value for inserting the + is

Hi nynaevelan
That's out of my control.
This added by "Fetch Annotations" to mark the book "read".

[chaley]

I looked at the code. It is using the 'Read tag' value from the catalog options, which defaults to a '+'. My guess is that you can turn off adding the tag by emptying that option in catalog setup.

Where would this be done?

If I remove this value manually, will it break anything later when I do another sync?

Click the dropdown arrow on Convert Books or right-click on a book in the library view, choose 'create catalog', select Epub or Mobi, change the option near the middle of the page, and push Apply.

I have no way of testing if making this change actually accomplishes what you want.
