leech VS Sigil

WebtoEpub Firefox addon, Leech, WebNovelConverter

I use a command-line tool called leech, which comes with some pre-built configurations for various sites and stories - including Worm. There are other story converter tools out there, and since FanFiction.net's recent API screwup changes I've used WebToEpub for that.

What problem are you running into getting Leech to work? I looked it up, and it seems like you mean this. I tested out locally, and it worked for me out of the box. Pip successfully installed poetry, and poetry installed all of the required components when called from inside leech-master. I did have to download with Royal Road instead of the original Fictionpress, possibly due to cloudflare blocking me for scraping too fast.

It's all at a very approachable level, too. I had to write an epub-maker as a necessary component for a project, and it turned out to be ~150 lines of python. You have to make a few indexes in XML and stick them into a zip file, basically.

As for editing your ePub file after compile, I definitely recommend either Calibre or Sigil. Either of these will be integral to a publication workflow, even if you get most of the job done with Scrivener. There is no better way to figure out what goes where or what an error message means if your book doesn't pass validation (and will help with validation itself so you don't run into that situation in the first place).

I recommend using Sigil for this kind of work, as you can see the changes you make to CSS in real time, and more easily find the exact element class names you'll need to work with.

If it reads like gibberish to you though, try using Sigil or this thing if it even works.

The second is Sigil, which is a great editor if you prefer to work with a GUI:

Download Calibre. Format your manuscript in Word how you want it to look and import it into Calibre to create an ePub file. Calibre does a very good job of translating your Word formatting into the HTML required for the ePUB file. If you want to do some tidying up to the ePUB file, download and use Sigil, which is a very good tool for editing ePub files. Both software tools are free.
