# pablotron.org
## Overview
[Hugo][] backend for [pablotron.org][].
Content is divided into three [sections][]:
|Section Type|Description|Permalinks|
|------------|-----------|---------|
|`posts`|Blog entries.|`/YYYY/MM/DD/SLUG/`|
|`articles`|Long-form articles.|`/articles/SLUG/`|
|`projects`|Programming projects.|`/SLUG/`|
The 10 most recent `posts` are shown on the home page blog in reverse
chronological order. A list of all `posts`, grouped by year, is shown
on the [archive][] page in reverse chronological order.
`articles` are long-form content that doesn't fit nicely as blog posts.
`projects` have a repository link and a brief description. Eventually I
may add more information (release history, signatures, etc).
Put assets (images, files, etc) for articles and posts in
`static/files/{articles|posts}/$SLUG`. Use the built-in `figure`
shortcode to reference images in content, because it supports more
attributes and is responsive (grep existing content for examples).
Use [mathyd][] to generate [SVGs][svg] for math posts and articles,
rather than pulling in [MathJax][].
## Usage
The `bin/new` script allows you (me) to quickly create new content by:
1. Expanding a section template ([Hugo][] calls these templates
"archetypes") draft content.
2. Opening the draft content in your editor.
## Add Post
To add a new post:
# easy version
bin/new post some-blog-post
# longer version
hugo new --editor $EDITOR posts/$(date +%Y-%m-%d)-some-blog-post.md
## Add Article
To add a new article:
# easy version
bin/new article some-article
# longer version
hugo new --editor $EDITOR articles/some-article.md
## Add Project
Update `data/projects.yaml` and then run `bin/gen-projects.rb`.
**Note:** If you want to add [Go][] module, you can set the `type` of
the entry to `go`, like so:
- name: "example-go-mod"
type: "go"
slug: "example-go-mod"
repo: "https://github.com/pablotron/example-go-mod"
text: "Example Go module."
Adding a `type: go` property in `data/projects.yaml` adds a `go_import`
property to the project front matter, which adds a `<meta
name="go-import" content="...">` element to the header of the generated
page.
## Edit Navbar Menu
To add or edit navbar menu entries:
# edit navbar menu entries
vim data/menu.yaml
## Serve Locally
To serve this site locally:
# serve hugo locally on port 1313
hugo serve -D --minify --disableFastRender
**Notes:**
* `-D` shows draft content,
* `--minify` generates minified HTML, and
[`html/template`][html-template] is aware of `<pre>` and `<code>` so
inline code blocks work correctly.
* `--disableFastRenderer` may be unnecessary, but the fast
renderer cache was giving me grief while doing theme development.
## Minify Images
Notes:
1. Use `svgmin` to shrink [SVGs][svg].
2. Use [`pngquant`][pngquant] to shrink [PNGs][png].
3. Use `gm convert -define web:lossless=true foo.{png,webp}`
to compress PNGs and convert them to `webp`s.
4. Use `gm convert foo.{png,webp}`
to compress JPEGs and convert them to to `webp`s.
5. Use the `pe-figure` shortcode for progressive enhanced `figure` tags
with a fallback image.
## Article Image Carousels
Articles support image "carousels" at the top and bottom of the page
(carousel is a bit of a misnomer, because the images are currently a
single row of identical-width columns).
See `content/articles/about.md` for a real example, but in general:
1. Add a `carousel` section to the article front matter with `top` or
`bottom` keys.
2. Add an array of images under `top` or `bottom`. The parameters for
the images are virtually identical to those used by the `pe-figure`
shortcode, with the addition of a `link` and `link_tip` keys.
Here is a reasonably complete example:
```yaml
carousel:
# top carousel (shown before content)
top:
- link: "/files/about/20231001-me-river.jpg"
link_tip: "Hi!"
css: "image"
sources:
- "/files/about/20231001-me-river-1024.webp"
- src: "/files/about/20231001-me-river-1024.webp"
width: 1024
height: 879
- link: "/files/about/20231110-me-fridge.jpg"
link_tip: "Fridge magnets, I guess?"
css: "image"
sources:
- "/files/about/20231110-me-fridge-1024.webp"
- src: "/files/about/20231110-me-fridge-1024.jpg"
width: 1024
height: 879
# bottom carousel (shown after content)
bottom:
- link: "/files/about/me-super-cool.jpg"
tip: "Younger me... Suave ;)."
css: "image"
sources:
- "/files/about/me-super-cool-1024.webp"
- src: "/files/about/me-super-cool-1024.jpg"
width: 1024
height: 655
```
## Deploy Site
To clone site repo:
```bash
# clone upstream repo (note wireguard hostname)
git clone k3.wg:/git/sites/pablotron.org.git
```
Then:
* make changes as usual
* commit changes
* push to upstream repo
The push will trigger a hook which runs
`/data/www/pablotron.org/data/bin/hook/deploy.rb`, which will:
1. Pull the latest changes from the git repository
2. Run [Hugo][] to rebuild the site.
3. Update the `htdocs` symlink for the live site.
4. Remove stale site builds.
5. Log the time taken for each step.
See `bin/hook/` for additional information.
# Theme
The current theme is `hugo-pt2021` and is stored in this repository as
`themes/hugo-pt2021`.
Includes the following shortcodes:
* `table`: Enhanced [CSS][]-only table shortcode. See
[hugo-shortcode-table][].
* `sup`: Superscript.
* `pe-picture`: Progressive enhancement `picture` shortcode.
* `pe-figure`: Progressive enhancement `figure` shortcode.
`hugo-pt2021` is depends on the following:
* [Bulma 0.9.3][bulma]: CSS framework.
* Several icons from [Feather Icons][feathericons].
The [Bulma][] [SASS][] is:
1. Stripped of extraneous styles. See `assetes/style.sass`.
2. Combined with a small amount of `pt2021`-specific styling. See
`assets/style.sass`.
2. Converted from [SASS][] to [CSS][], minified, and fingerprinted
using [Hugo Pipes][hugo-pipes]. See `layouts/partials/head.html`.
3. Written to `public/style.$HASH.css`.
