pycobello 0.1.1a0

A blazing fast, dependency-light static site generator

pycobello

A blazing fast, dependency-light static site generator (SSG) for Python 3.12+.

• Markdown + YAML front matter → HTML
• Jinja2 themes (.html templates)
• CLI-first (Typer): init, new, build, preview, check, deploy
• Incremental builds with a JSON cache and write-avoidance by content hash
• Preview server via stdlib http.server; optional --watch with [watch] extra
• Diagnostics (check): duplicate URLs, required front matter, internal links
• Plugin system via Python entry points (pycobello.plugins)

Install

uv add pycobello
# or
pip install pycobello

Optional watch support (live rebuild on file changes):

uv add "pycobello[watch]"

Quick start
