Ask AI it will write one for you pretty well that you can then modify.

Sure, but how can I repack book after have modified some files ?

Repackaging happens automatically when you click the rebuild book button.

Many thanks, Kovid. I didn't understand because I thought that it was in Calibre-editor. I looked in Calibre main program, and all is clearer

I asked to Chat-GPT. It created a simple plugin that appears in "EditBookTool" category. Also, when I boot Calibre in debuging mode, log file contains this line :
Successfully initialized third party plugins: Italic spans to I (0, 5, 0)
where "Italic spans to I" is my plugin.
But no "Italic spans to I" button appears in any toolbars, nor in Calibre main, neither in Calibre-editor.
Why ?
And, have I to ask this question in the forum Plugin section ?

In the editor : menu Edit / Prefs, Icone Toolbars, choose a toolbar and add your plugin

Thanks, but my plugin is not in any left list ("Actions available")

You have to install it first with calibre (the main interface), It must be in a form of a zip file,
Button Prefs, section "Advanced", Plugin, button "Load plugin from file".

Restart Calibre.
Then you'll be able to put it in a toolbar of the editor,

That is all I did. As I said :

More : on Calibre main, menu Pref/Plugins, I see my plugin in EditBook tool catagory. So, I presume that it is well installed. And booting log says "Successfully installed...".
But no way, in Calibre main neither in Calibre-editor, to discover it anywhere, even when I try to add it to some toolbar.

Maybe it goes in error at starting, after the rough initialization. Try to start calibre or editor in a terminal and see the output. You can also put some debug msgs in your plugin (a print() will be shown in the terminal output) to see if it loads completely, or where it aborts if it's the case.

Well, I won't learn you how to debug, I suppose you already know all that.

A tip : if you change your code, no need to reinstall the plugin, just update the zip and restart calibre or editor.
