Developing plugins (python3)

[rigogsilva]

I have been looking at the docs on how to build a calibre plugin, but can't find I can't find some detail information.

Do I need to install the whole calibre library? Is there a pip install calibre library? Newby here so, need some more details if anyone can help.

Also, I am trying to this in python3. R.I.P 2.7.

Thank you!!!

You dont need to install anything other than calibre itself. If you want to use python 3 then install the calibre python 3 betas from https://www.mobileread.com/forums/sh...d.php?t=325721

And see https://manual.calibre-ebook.com/creating_plugins.html

Ok, so I have calibre installed. I also created the __init__.py. When I run the command “ calibre-customize -b .” it fails. Do I need to copy the calibre-customize from the applications folder into my plugin folder?

My folder structure is:
/rigo/calibre-plugin
/__init__.py

fails with what error and a plugin is a directory containing __init__.py and a txt file with the plugins import name

If you are on macOS, then read the note: https://manual.calibre-ebook.com/gen...cli-index.html

rigo$ calibre-customize -b .
bash: calibre-customize: command not found

It can’t access that command. That is why I asked, I needed to move the `calibre-customize` file into the folder where the init file is.

Also, when trying to import calibre in the __init__.py file, it doesn’t really recognize calibre because that wan’t installed as a python library and the folder that has the init file doesn’t really have that `calibre` module. So may be missing something.

the good news is that I can apply the plugin by using the absolute path: "/Applications/calibre.app/Contents/MacOS/calibre-customize -b ." in my directory. That works fine and applies the plugin.

The other issue I am having is when developing the library. My text editor doesn't know that calibre exists so when I write:

from calibre.customize import FileTypePlugin"

I don't get any library hints. Do I need to `pip` install a calibre library to get those hints?

Depends on how your editor does hinting. You cannot install calibre as library, but you can add the PATh to the calibre source code to PYTHONPATH.
