- Restore HTML link extraction in LinkValidator (removed in a83634d
under the false premise that post bodies are raw markdown; they
are HTML rendered by NimblePublisher at compile time). The missing
regex made extract_links/1 find zero links, silently disabling
compile-time validation.
- Support /blog/{blog_id}/tag/{tag} links: validate blog ID,
require non-empty tag (tags are user-defined, e.g. pi.dev).
- Fix invalid links in two posts: tag/Pi.dev -> tag/pi.dev,
2026-07-13-synthetic-tdd.md -> synthetic-tdd.
- Fix test warnings: use Plug.Test deprecation, unused import,
runtime-defined TestBlogValid module.
- Add regression tests for HTML extraction and tag page links.
External links in post bodies now open in a new tab and show a
box-with-arrow marker icon, so readers can tell at a glance which
links leave the site.
- blogex: new Blogex.ExternalLinks.rewrite/1 marks up anchors with
http(s) hrefs at compile time with target="_blank", rel="noopener"
and class="blogex-external" (idempotent, merges into existing
class/rel values, leaves relative, mailto: and #anchor links alone)
- blogex: Post.build/3 applies the rewrite, so every blog gets it
- app: CSS in .blogex-post-body draws the marker via a mask so it
inherits the link colour; empty ::after content stays invisible
to screen readers
- make test now also runs the blogex suite; it is currently red
with 3 pre-existing blog_integration_test failures caused by the
vacuous link validator (parked yak
link-validator-never-sees-compiled-html-...)
- Drop redundant :ok return in _validate_links/2 (blog.ex)
- Remove dead HTML link regex from extract_links/1 (body is raw markdown)
- Rename slug_slug_end/1 to slug_end/1
- Simplify parse_blog_link/1 to return {blog_id, slug}, removing
parse_query_fragment/1 and dead case branches
- all_posts/0 now excludes posts where date > today
- all_tags/0 computed at runtime from filtered posts
- posts_by_tag/1 and recent_posts/1 inherit date filtering
- Add unfiltered_posts/0 to Blog macro and FakeBlog
- Add all_posts_unfiltered/0 to Registry for dashboard use
Goal: have a personal blog, and try out another point in the 'modular
app design with elixir' space.
Designing OTP systems with elixir had some interesting ideas.
