In epub converting calibre auto split file in header. Why not create toc from header.
 

I am converting .md file to epub. Then I have some advice.

1. can convertion use filename as title in default if there is no title found in md meta?

2. calibre split file in header h*, so why not create e-book toc from headers in default?

Auto generate might have unwanted effects. :angry: :eek:
(I find it amazing how many self Pub's still use H tags for big and bolder. Chap #, Chap Title, Time-Place. That can make for a pretty busy TOC just for the Start of a chapter :rolleyes:)

Calibre already has a stand alone TOC tool (you can add it to your Toolbar) that allow a choice. (I think this is the exact same one as built into the book editor)

So how to use this TOC tool in ebook-convert.exe cli? Is the --toc-title opinion? I mean to form a toc with h1-h6 in epub

By Standalone, I meant part of the main Calibre GUI as opposed to the e-book editor.

I don't use the CLI convert option. The main GUI has
Preferences:Common options: Structure Detections
where you set an xpath template

And I hardly use calibre gui. I use calibre as ebook-viewer (gui) and ebook-converter (cli).

It's because if I do not use converter in cli, I need to open gui, add book, convert, copy/export converted file, remove file from calibre.

You can call the Editor from the CLI, and use the tools there without adding to calibre.

Convert is separate. But my original suggestion was more of a 'look for similar' in the CLI documentation

--level1-toc --level2-toc and --level3-toc

Thanks. By the way, what is the difference between //h:h1 and //h1 in xpath?
