kpress 0.2.2

Reusable document rendering and publishing layer for KPress-format documents.

KPress

KPress is a Python library and CLI that turns Markdown into polished HTML documents and static sites. It owns document rendering, typography, reader interactions, and the build pipeline while leaving site semantics and deployment to the consuming project.

KPress 0.2.2 is an alpha for developers evaluating it in real projects. The document and publishing paths are usable and tested, but public seams may change by hard cut before a stable release.

KPress requires Python 3.12 or newer. KPress 0.2.2 supports macOS and Linux; native Windows support is tracked for a later alpha (kpr-isp2).

Install and Build a Site

Install the released package into a project:

uv add kpress==0.2.2

Create this minimal kpress.yml:

sources:
  - path: content

publish:
  output_dir: public
  asset_mode: hashed

Then add a document and build it:

mkdir -p content
printf '# Hello\n\nBuilt with KPress.\n' > content/index.md
uv run kpress build
python -m http.server 8080 -d public

Open http://127.0.0.1:8080/. The build writes public/index.html, the packaged reader assets under public/_kpress/assets/, and a deterministic build manifest at public/_kpress/kpress-manifest.json.

hashed fingerprints KPress-owned CSS and JavaScript for production caching. KPress copies eligible project-local media without rewriting its authored URLs and does not fetch or verify external assets or seal a complete asset graph. Use linked for readable local asset names and hosted when an embedding application serves KPress assets itself. Truly self-contained single-file and verified offline output are not part of 0.2.2.

Use KPress as a Library

File-based sites can call the same publisher used by the CLI:

from kpress.publish import build_site

report = build_site("kpress.yml")
print(report.routes)

Python hosts can instead construct a typed KPressConfig, render a standalone page with kpress.format.render_page, or render an embeddable fragment with kpress.format.render_fragment. Each render returns a typed, complete asset manifest; hosts can materialize its package closure with kpress.format.materialize_package_assets and emit tags only for its browser entry points.

The three runnable examples cover the supported integration shapes:

• examples/static-site/: KPress owns a complete static site.
• examples/wrapped-site/: an outer site shell embeds KPress fragments and serves the asset closure.
• examples/single-doc/: a typed, programmatic build with no YAML config.

See examples/README.md for commands and docs/kpress-static-publish.runbook.md for the publisher boundary.

What Ships

• Vendored PT Serif and Source Sans 3, design tokens, light/dark/system modes, print CSS, and a no-flash theme bootstrap.
• Progressive reader features: table of contents, footnote and link tooltips, code copy, tabs, video placeholders, responsive tables, and KaTeX math with MathML.
• Static discovery and routing, sitemap/robots/redirects, content-hashed package assets, optional optimization and precompression, and schema-versioned manifests.
• Typed Python APIs, native ESM browser modules, host-owned chrome slots, runtime widget/behavior registries, and sanitized or trusted raw-HTML modes.

Documentation

docs/README.md is the documentation index. It links the architecture and public-contract reference, installation and development guides, publishing guidance, validation runbooks, and release notes.

Development and Unreleased Versions

External evaluators should start with the tagged package. Projects deliberately dogfooding unreleased work may pin an exact upstream commit or a maintained fork, but should treat that as a separate, faster-moving consumption path and record the pin.

make install
make verify

Architecture and stability contracts live in docs/kpress-design.md. Current capability status, release gates, and the prioritized public backlog live in TODO.md. See CONTRIBUTING.md, SECURITY.md, and SUPPLY-CHAIN-SECURITY.md before contributing or reporting a vulnerability. General defects and integration feedback belong in the issue tracker.

Compatibility Policy

KPress evolves by hard cuts during the alpha: there are no deprecation shims. An out-of-date caller should fail loudly rather than appear to work. The supported surface is pinned in kpress.contract; public-name changes update the contract, docs, tests, goldens, and release notes together.
