This page will be updated in the future, but hey! This exists!
ChiveGen is just what the title says: a static website generator designed specifically for fanfiction archives. It runs from the command line, and turns a folder of (specially formatted) text files into a simple static HTML website.
ChiveGen is currently on version 0.2.12. You can check out a current demo here.
ChiveGen is intended to be highly customizable, with a number of command line options and lots of replacable templates, so with enough creativity you can make your archive look nearly however you like. (Technically you could even kludge it into a blog or something! But I would not recommend this.)
No, really. If you know that <i></i> makes italics, <u></u> makes underline, and <b></b> makes bold, you're pretty much set! The Casual HTML option will put those pesky <p></p> tags on for you (or you can use an online converter if desired), and everything else is just templates.
It's no Hugo, but the Demo archive you see above was fully generated in under a second! (Current average time for it was ~900ms?)
Compile it on your own computer, if you want. Or you can get the nice binaries and a shell script to run them for you all nice and tidy looking.
ChiveGen is intended to be free and open source when it's done, though I have not yet chosen a license (and until it's actually ready to release, that feels like putting the cart a feeew yards ahead of the horse, haha.)
Things that might be added on the roadmap.
