my first plugin did not work

[yang738]

I　have tried the hello world plugin , but it didn't work.

I have set up the environment variable: calibre_develop_from.

D:\Development\Calibredev>dir

25/07/2014 11:57 1,070 __init__.py

D:\Development\Calibredev>calibre-customize -b .
Plugin updated: Hello World Plugin (1, 0, 0)


I added a txt file to calibre , and converted into epub file.

I hope to change the metadata during the converting, just like what the hello world plugin did. but it didn't change anything.

the following is the hello world plugin : any one can kindly help me to do the first plugin? thanks in advance.


import os
from calibre.customize import FileTypePlugin

class HelloWorld(FileTypePlugin):

name = 'Hello World Plugin' # Name of the plugin
description = 'Set the publisher to Hello World for all new conversions'
supported_platforms = ['windows', 'osx', 'linux'] # Platforms this plugin will run on
author = 'Acme Inc.' # The author of this plugin
version = (1, 0, 0) # The version number of this plugin
file_types = set(['epub', 'txt']) # The file types that this plugin will be applied to
on_postprocess = True # Run this plugin after conversion is complete
minimum_calibre_version = (0, 7, 53)

def run(self, path_to_ebook):
from calibre.ebooks.metadata.meta import get_metadata, set_metadata
file = open(path_to_ebook, 'r+b')
ext = os.path.splitext(path_to_ebook)[-1][1:].lower()
mi = get_metadata(file, ext)
mi.publisher = 'Hello World'
set_metadata(file, mi, ext)
return path_to_ebook

actually, I want to develop a plugin with the following function:

1: it can get meta from txt file and update the calibre metadata.

2:it can update the metadata when I select one file and click a button.


who can kindly guide to complete this plugin? thanks.

As with all things plugin related, you should look at kiwidude's plugins. For this, there is already the Import List plugin. While it is intended for creating books from a list, one of the features listed is "Option to update metadata of existing books". Odds are you can use this plugin directly, or use it as a base for your own.

The command is wrong for Windows. It should be:

echo  %CALIBRE_DEVELOP_FROM%
