Sign-In Doors on a Static Page
The new signin tile renders Sign in with Apple, Sign in with Google, and a magic-link email form against a site-owned auth API, storing nothing in the page.
Updates
What is new in TileDown, newest first. Each post is dated, tagged, and built with the very capability it describes, so this list doubles as living coverage: article layout, tag chips, post listing, RSS, share links, and the latest-posts block on the home page.
TileDown 0.4.1 ships static code color
TileDown 0.4.1 adds build-time syntax highlighting, safer tag clearing, and broader example-site checks without adding a client-side highlighter.
The birthday paradox
In a room of 23 people the odds two share a birthday are better than even. A clean demonstration that uses a formula, a chart, and a table, all rendered to static SVG at build time.
Interactive Charts
When a chart needs richer hover behavior, TileDown renders it as an interactive tile that ships a small script for a styled, cursor-following tooltip.
Math in Markdown
Write TeX math in a Markdown block and TileDown typesets it to static SVG at build time. No client-side JavaScript, no web font, no MathJax. The glyphs are real outlines, the layout is exact, and it follows your light or dark theme.
The math engine, in your browser
TileDown renders math to static SVG at build time, no server and no client-side JavaScript. The same pure-Swift engine also compiles to WebAssembly, so you can type TeX and watch it render live in your browser. Try the playground.
The PDF engine, in your browser
TileDown builds a typeset PDF of every article at build time with a pure-Swift engine. The same engine compiles to WebAssembly, so you can type Markdown and get a real PDF generated entirely in your browser, no server. Try the playground.
Charts in Markdown
Author charts inline with a fenced code block. TileDown renders static SVG, no client runtime, using the same notation as MarkdownPDF.
Diagrams in Markdown
Author diagrams inline with a fenced mermaid block. Flowcharts render through the mermaid runtime; a pie renders as a static SVG chart, matching MarkdownPDF.
Default Article Style
A publication-style post that demonstrates hero imagery, metadata, tags, and social sharing.
Interactive Tiles
Typed tiles can render scoped browser behavior while the rest of the page remains static.
Publishing Pipeline
The public website is built from source content on Linux and deployed as static files.
Tag Intersections
Tag pages can narrow content by selecting multiple tags together.
Markdown as Canonical Source
TileDown keeps Markdown on disk as the source of truth while deriving typed output.
Browser-Visible Tiles
Some TileDown behavior only proves itself inside a browser.
Linux-First Builds
The engine targets macOS and Linux, so generated browser behavior is checked on Linux too.
Slug Overrides and References
A source folder can publish at a different slug while references still resolve.
Service Contracts Are Next
The service-form internals are tested, but the CLI still needs configuration loading.
