make validate # quick HTML syntax check (search for unclosed tags)
make tidy # run html-tidy on every .html (warnings only)
make video NAME=foo # regenerate the ASCII background from video/foo.mp4
```
## Animated ASCII body background
> **Note:** `make serve` reads from the working tree (so it picks up the latest
> `static/js/mountain.js` after a `make video`). For a production build, use
> `nix run .#serve` — but note that the Nix build only includes **git-tracked**
> files, so you must `git add` your new `mountain.js` (and any other new files)
> before `nix run .#serve` will pick them up.
The page background is **animated ASCII art** generated by
[`chafa`](https://github.com/hpjansson/chafa) from a stripped-down version
of the Open Graph card (`static/img/og-image-bg.svg` — black background,
grid, the `tui-pages` wordmark, the "A framework for / building TUIs in
Rust." headline, and the subtitle, with the install button cropped out
because chafa was rendering it as a row of `@` symbols). The art is plain
text inside `<pre>` blocks; the animation is pure CSS.
## Animated ASCII video background
```
static/ascii/rain.txt ← 240 × ~50 grid of og-image-bg.svg
```
The page background is an **animated chafa ASCII playback of a video**, running
at 12 fps behind the entire page. `ffmpeg` extracts frames from a video you
provide; `chafa` converts each frame to an 80 × 24 ASCII grid; a bundler
(`tools/build_mountain_js.py`) concatenates all grids into a single JS array
(`static/js/mountain.js`). A tiny cycler (`static/js/mountain-bg.js`) swaps
`textContent` on a single `<pre>` every ~83 ms.
To re-render after changing the source SVG (you need `chafa` on `$PATH`,
or run inside `nix develop`):
### Swap the video
1. Drop a `.mp4` in `video/`:
```bash
cp ~/Videos/my-clip.mp4 video/myclip.mp4
```
2. Build it into the site (run inside the nix dev shell for ffmpeg + chafa):
```bash
nix develop -c make video NAME=myclip
```
This runs three steps:
- `make video-frames NAME=myclip` — `ffmpeg` extracts PNGs at 12 fps into `build/myclip/`, then `chafa -s 80x24 --symbols ascii` produces ASCII for each
- `make video-bundle NAME=myclip` — bundles all `frame-*.txt` into `static/js/mountain.js`
- the wrapper `make video` does both
3. Serve and view:
```bash
make serve
# → http://localhost:8000
```
### Helper targets
```bash
make ascii
make video-list # show available videos in video/
make video-frames NAME=foo # only extract + chafa, skip the bundle
make video-bundle NAME=foo # only re-bundle from an existing build/foo/
```
The source SVG is committed (`static/img/og-image-bg.svg`) so `make ascii`
is fully reproducible — no ImageMagick, no cropping step.
### Tuning
- **Frame rate** — edit `Makefile` `fps=12` in the `video-frames` target. If
you change it, also update `TP_MOUNTAIN_FPS` at the bottom of
`static/js/mountain.js` (regenerated automatically each `make video`).
- **ASCII resolution** — `-s 80x24` in the `chafa` call. Wider/higher = larger
bundle, more detail.
- **Bundle size** — the resulting `static/js/mountain.js` is `~1.7 kB × N_FRAMES`
(333 kB for a 15 s clip at 12 fps). For long videos, drop `fps` or downscale
the source video first.
```
↓ chafa -s 80x24
build/mountain/frame-*.txt intermediate ASCII grids
↓
static/js/mountain.js bundled 60-frame array (≈120 kB)
↓ requestAnimationFrame
DOM <pre.tp-mountain-frame> what you actually see, 12 fps
```
To re-render (you need `chafa` and `python3` on `$PATH`, or use `nix develop`):
```bash
make mountain # frames + bundle, end-to-end
make mountain-frames # just the PNG + ASCII frames
make mountain-bundle # just rebundle the JS array from existing frames
```
### How it's wired
- A single `<div class="tp-ascii-rain" aria-hidden="true">` is placed at
the top of `<body>`, fixed full-bleed, with `z-index: -1` and
`pointer-events: none` so it never blocks the UI.
- Inside, a `<pre class="tp-ascii-rain-track">` holds **two byte-identical
copies** of the chafa output stacked vertically for a seamless
`translateY(0 → -50%)` loop over 90 s.
- Color is `#f4a26b` (warm rust-orange) at 14% opacity with a faint
`text-shadow` glow — picks up the brand colour and reads as a subtle
background, not a wall of `@` blocks.
- A `::after` overlay draws a 2 px CRT scanline pattern that ticks
downward at 8 s/cycle.
- The hero section has a `.tp-ascii-hero-overlay` class that paints a
vertical gradient over the top of the page, so the hero text stays
readable while the ASCII art shows through on the bottom half and below.
- The light theme inverts to dark text on light, dimmer, no glow.
- All animations are disabled inside
`@media (prefers-reduced-motion: reduce)`.
- `static/js/mountain.js` exposes `window.TP_MOUNTAIN_FRAMES` (an array of
60 template strings) plus `TP_MOUNTAIN_N_FRAMES = 60` and
`TP_MOUNTAIN_FPS = 12`.
- `static/js/mountain-bg.js` mounts a `<pre class="tp-mountain-frame"
aria-hidden="true">` to `document.body`, sets the first frame as
`textContent`, then cycles with `requestAnimationFrame` and a
`setInterval`-style accumulator so frame drops don't desync.
- The script pauses when `document.hidden` is true (no wasted CPU on
backgrounded tabs) and respects `prefers-reduced-motion: reduce` by
showing a single mid-loop frame and not animating.
- Style lives in `static/css/ascii.css`:
- `position: fixed; inset: 0; z-index: 0` — full-bleed, behind page content
- `color: #f4a26b` (rust-orange) with a 0.45 opacity and a soft
`text-shadow` glow — picks up the brand colour
- `font-family: 'JetBrains Mono'` for the in-browser renderer
- A `::after` pseudo-element overlays a 2 px CRT scanline pattern that
ticks downward at 8 s/cycle
- Light theme (`data-theme="winter"`) drops the glow, dims the opacity
to 0.20, and switches the scanlines to white-on-transparent
- The scanline animation is killed inside
`@media (prefers-reduced-motion: reduce)`
The hero (`#hero`) is **not** animated — it keeps the original static
`static/img/terminal-default.svg` mockup, exactly as designed.
The hero (`#hero`) is **not** part of the mountain background — it keeps
the original static `static/img/terminal-default.svg` mockup, exactly as
designed. The terminal sits on top of the mountain as a discrete card.
### Tuning the animation
The renderer is parameterized at the top of `tools/mountain.py`:
| Constant | Default | What it does |
| --- | --- | --- |
| `W, H` | 320 × 200 | Output PNG resolution |
| `N_FRAMES` | 60 | How long the loop is |
| `HORIZON_FRAC` | 0.45 | Sky height as a fraction of the image |
| `SEED` | deterministic | Heightmap random seed |
| `STEPS` | 80 | Forward steps per frame in camera space |
Bump `W`/`H` for sharper terrain, or `--symbols ascii+block+half` in the
chafa call inside `tools/build_mountain_js.py` for denser glyphs. Both
changes require a `make mountain` rebuild and a higher page weight
(mountain.js is currently ≈120 kB).
