🕸 itsybitsy

Serve folders of Markdown to different domains over HTTP, Spartan and Nex, rendered on the fly with no build step.

A Rust re-implementation of smolweb, which serves one folder from one process with its output formats hardcoded and its configuration in per-file frontmatter. itsybitsy changes all three: one process serves many domains, each output format is a separate crate behind a cargo feature, and configuration lives in a TOML file per content directory.

Status

Early. The configuration layer is implemented and tested; nothing is served yet.

Area	State
Server configuration, virtual hosts, --check	implemented
Path resolution and the render cache	planned
gemtext and HTML output	planned
HTTP, Spartan and Nex listeners	planned
80-column text and Nex output	planned
WML and XHTML-MP decks	planned
Gemini and Gopher	planned

Configuration

Two files. A server file names the virtual hosts and the listeners:

version = 1

[site.smol]
root = "/srv/smol/content"
hosts = ["smol.place", "www.smol.place"]

[listener.web]
protocol = "http"
bind = "0.0.0.0:8080"
formats = ["xhtmlmp", "html"]
default_site = "smol"

A .itsybitsy.toml in any content directory says how the Markdown in that directory renders. There is no inheritance: a subdirectory without its own file uses the built-in defaults rather than its parent's. Repetition in a deep tree is the price of never having to look elsewhere to know how a page renders.

--check validates the configuration and reports the routing it resolved, without binding a port:

$ itsybitsy --config /etc/itsybitsy.toml --check
sites:
  smol: /srv/smol/content
hosts:
  smol.place -> smol
  www.smol.place -> smol
listeners:
  web: http on 0.0.0.0:8080 [xhtmlmp, html] by host, default smol
formats rendered per page: html, xhtmlmp

Everything the schema cannot express is checked here rather than on first request: a format no enabled feature provides, two sites claiming one hostname, a content root that does not exist, a server file sitting inside a content root where it would be served.
