Nifty. That'll be very nice. What are the limitations? Access to the library db would be nice, but I don't expect it given the issues with concurrent update.

Glad it's working for you. As per Kovid's new plugin CLI feature, I'll be adding CLI via calibre to my plugins in future.

Count Pages Plugin

Whose pages? EPUB does not have 'pages'.

Kiwidude made the Count Pages PI with the ability to chose from a number of differing count algorithms.

There are no limitations, you can do anything that any of calibre's own command line utilities can do.

Kovid,

I've been playing with this and with a bit of work I'm able to get my existing CLI interfaces to run using 'calibre-debug --run-plugin'. That's pretty cool.

However, while figuring out how to get at the config preferences my PI has stored in db.prefs.get/set_namespaced, I realized that calibre-debug doesn't have the '--with-library' option that calibredb does. I can relatively easily get the db for the library last used in the gui, but not a specified one.

If CLI plugins are meant to be able to access/update library db's, might it be better to make run_plugin a command under calibredb and pass the db in to cli_main?

I finally made myself a working src dir for calibre, so I can do the coding for this approach and submit it for your review, if you like.

If your plugin needs access to the db, you can add a --with-library option to your plugin. Then do

calibre-debug -r "plugin name" -- --with-library /whatever

Count Pages Plugin

Hi Jim,

Is there any option to split the epub on the basis of words or page numbers?

Not in EpubSplit.

Word count is somewhat variable depending on who's doing the counting and page numbers are vary widely, again depending on who's doing the counting.

cakiran · 03-14-2013, 02:45 PM

Thanks for the clarification.

Is there any way to do this on the basis of pages? Can we cut out pages within a chapter?
Is that possible at all?

JimmXinu · 03-14-2013, 02:49 PM

I'm not aware of any existing way. Frankly, I can't imagine why you'd want to.

cakiran · 03-14-2013, 04:02 PM

This is for creating previews or excerpts out of these books.

cakiran · 03-14-2013, 04:10 PM

Can you think of any vague idea of how this may be proceeded with? Like splitting on the basis of number of words or pages?

JimmXinu · 03-14-2013, 04:33 PM

I can think of ways that might do it, sure.

You could look inside the Count Pages plugin for ideas on how to count pages and words to find where you want to split.

After that, you could look at the splitHtml() function in my epubsplit.py for ideas on how to extract only desired ranges of HTML.

Or you could maybe use epubsplit as-is by Inserting an anchor tag at the point you want to split (found by counting words/pages) and add it to the TOC. Then use epubsplit.

cakiran · 03-14-2013, 05:47 PM

Thank you for the ideas. Very helpful.

Can you please give step by step of how to do this. As I understand
1. Get the word count and get the page, at the html page which need to be split add a anchor tag with some text like

<html>
....
<body>
<p>lorunm dfdsfds hjfldsf</p>
<a>cuthere</a>
<p>lorunm dfdsfds hjfldsf</p>
</body>
</html>

Now i ran this through the epubsplit options generator and it did nothing without adding anything to TOC.

Then add this do TOC? You mean the Table of contents page? Add a new entry? How can i do that. Step by step will help greatly.

Thanks.
