## [0.1.0] — 2026-06-20
First public release: a small, file-based Markdown blog engine in CRuby. Posts
are plain files, the engine exposes them as a JSON API and ships a self-hosted
admin — no database, no external services.
### Added
**Content & storage**
- File-based store: each post is a `.md` file with a TOML frontmatter block
delimited by `+++`. No database.
- Post fields: `title`, `slug`, `date`, `lang`, `author`, `tags`, `draft`,
`excerpt`, `cover`, `all_langs`, and `translations` (a `lang → slug` map).
- Drafts (`draft = true`) are hidden from the public API.
- Excerpt falls back to the first paragraph (~200 chars) when none is set.
- Estimated reading time (~200 words/min) computed per post.
- Multilingual posts: per-language slugs via `translations`, plus `all_langs`
to surface a single post under every language.
**Markdown rendering**
- GFM rendering via kramdown: tables, fenced code blocks, task lists, and
strikethrough.
- Automatic heading IDs for in-page anchors.
- Raw HTML in post bodies is passed through (authors are the trusted admin).
**Public JSON API (`/api/volumen`)**
- Read-only endpoints: `site`, `posts`, `posts/{slug}`, `tags`, `feed.xml`
(RSS), and `sitemap.xml`.
- `posts` supports pagination (`page`, `limit`, returning `total` and
`page_size`) and filtering by `lang` and `tag`.
- Permissive CORS so a separate front end can consume the API.
**Admin (`/admin`)**
- Server-rendered admin with a sidebar layout and full post CRUD.
- Dual-mode editor: Markdown source (primary) and a visual WYSIWYG, switchable
per post, with a toggleable live preview persisted across sessions.
- Image upload from the editor toolbar into `content_dir/media`; any image
format is accepted (WebP and AVIF included) and served with the correct
`Content-Type`.
- Cover image field with upload, URL, clear, and preview.
**Multi-user & roles**
- Multiple admin users stored in `users.toml`, managed from a settings page.
- Two roles: `admin` (full access incl. user management) and `author` (posts
only).
- Change password and username; last-admin and self-deletion safeguards.
**Configuration & CLI**
- TOML configuration, auto-generated with a commented template on first run.
- Configurable `host`/`port` (defaults to `9090`), `content_dir`,
`users_file`, and `site` metadata.
- CLI: `serve`, `hash-password`, `version`, `help`, with `--config`,
`--content`, `--host`, and `--port` overrides.
**Deployment**
- `install.sh` installs the Ruby toolchain from distro packages on Fedora and
openEuler (and prints guidance on other distros), creates the service user
and directories, and installs a systemd unit.
- Deployment docs for systemd and FreeBSD (`rc.d`), plus an nginx reverse-proxy
setup that runs the admin same-origin, with brute-force rate-limiting and an
optional IP allowlist on the login endpoint.
**Project & tooling**
- Documentation set: architecture, configuration, API reference, deployment,
and security.
- `just` task set (`install`, `run`, `dev`, `build`, `test`, `uninstall`) and
Forgejo Actions CI (RuboCop + tests on Ruby 3.3/3.4, gem build on release).
- `CONTRIBUTING.md` and a minitest suite; clean RuboCop.
### Security
- Passwords hashed with scrypt and verified in constant time.
- Per-form CSRF tokens on every state-changing admin request.
- Session cookies are `HttpOnly` and `SameSite=Strict`, and gain the `Secure`
attribute automatically on HTTPS requests (detected via `request.ssl?` /
`X-Forwarded-Proto`), so the cookie never travels over plain HTTP in
production.
- Configurable, stable `session_key` so sessions survive restarts.
- Generic login error message to avoid username enumeration.
