GFM Extensions (AC6)

This text is ~~struck through~~ to prove strikethrough.

A task list:

An unfinished task
A finished task

A bare autolinked URL: https://themarkdownweb.com

Escaping (AC6)

A literal less-than < and ampersand & must be HTML-escaped.

Inline code with <tags> & ampersand must also escape its angle brackets and ampersand.

Links (AC: 2.3)

Internal .md links (rewritten to page routes at build time):

A same-dir internal link: guide (-> /gear-guide)
A nested internal link: nested (-> /sub/page)
A cross-file fragment link: other heading (-> /gear-guide#heading-one)
A space-in-filename link: notes space (-> /my-notes)
A percent-encoded link: notes encoded (-> /my-notes)
A mixed-case link: Gear Guide cased (-> /gear-guide)
An index-collapse link: sub index (-> /sub)
A malformed-escape link: malformed (left unrewritten)
An escape-the-vault link: escape (left unrewritten)
An encoded leading-slash link: encoded leading slash (left unrewritten, never //foo)
An encoded interior-slash link: encoded interior slash (left unrewritten, never split into /a/b)
An encoded path-traversal link: encoded passwd (left unrewritten, never //etc/passwd)
An empty-basename link: empty basename (left unrewritten, never /)
A broken internal link: missing (-> /does-not-exist, lands on 404)

Pass-through links (left exactly as authored):

A same-page anchor: jump to lists
An external link: the site
A mailto link: mail us
A root-absolute link: already a route
A non-.md asset link: a pdf

Media (AC: 2.4)

These media embeds are authored as raw HTML so the relative src/poster values reach the build-time rehype media rewrite as plain HAST <img>/<video>/ <audio>/<source> element nodes (the same node set a markdown ![]() embed lowers to), and so a missing-asset reference cannot hard-crash Astro’s image pipeline. The rewrite is at the HAST stage, so it is syntax-agnostic.

The epic same-dir embed with alt text (AC1/AC4): a skier in deep powder

An empty-alt decorative embed (AC4):

A leading ./ embed collapses (AC2): dot slash

An image carrying title/width/height that must survive the rewrite (AC4): titled

Pass-through media, left exactly as authored (AC3):

F1 smuggling guards, left UNREWRITTEN (AC2 / rows 12-14):

A missing-asset embed still rewrites to its would-be served path and 404s, never crashing the build (AC6): broken

A raw-HTML video with a relative poster and a nested relative <source> (AC5):

A raw-HTML audio with a relative src (AC5):

The AC1 epic example authored as LITERAL markdown ![]() (not raw HTML) — proves the markdown image syntax flows through the same rewrite and bypasses Astro’s astro:assets/_astro optimisation, emitting a plain served <img> (AC1):
