New favicon_png (and favicon_png_sizes)
fields for social_meta(), write_manifest(),
and init_meta(). Add a PNG fallback alongside an SVG
favicon: Chromium-based browsers (Chrome, Edge, Comet,
etc.) don’t render SVG favicons in the address bar and fall back to a
generic globe icon without one, even though the browser tab shows the
SVG correctly. favicon_png_sizes defaults to
"32x32".
Added openai_image_generator(), a ready-made
generator for generate_assets() that calls
OpenAI’s image API (gpt-image-1 by default) and returns the
generated image bytes. It is shinyseo’s only built-in generator:
OpenAI’s image API is a clean fit for this job (one endpoint, one
request shape, raster bytes back), and the httr package it
needs is an optional Suggests dependency loaded only when
the constructor is called.
Other LLM vendors are welcome as community-contributed generators –
see the new “Contributing a generator” section in LLM.md
for the shape a contribution should take. Notably, Claude/Anthropic has
no image-generation API (it can see images but not generate them), so no
“Claude generator” is shipped or planned as a parallel to the OpenAI
one.
init_meta() no longer discards fields it does not
ask about. Re-running the wizard on an existing meta.yml
used to silently drop hand-added fields such as
google_site_verification, robots,
image_alt, and custom; they are now carried
over untouched. Answering “no” to the PWA question still removes the
manifest-related fields, since that is an explicit choice.
favicon_mime() now recognises
.jpg/.jpeg favicons as image/jpeg
instead of falling back to image/x-icon.
update_meta()’s client-side handler now removes
og:image:width, og:image:height,
og:image:type, og:image:alt, and
twitter:image:alt when the share image is replaced at
runtime, instead of leaving values that described the old
image.
generate_assets() now detects the image format of
raw bytes returned by a generator (PNG, JPEG, GIF, WebP) from their
magic numbers instead of assuming PNG.
openai_image_generator() reports the HTTP status
line when an error response is not JSON (e.g. HTML from a proxy),
instead of failing with a parse error, and rejects unknown asset kinds
with a clear message.
DESCRIPTION no longer declares LazyData
(the package has no data directory), and its
URL/BugReports now point at the package’s
actual GitHub repository.
generate_assets(), which fills in a missing
favicon, apple_touch_icon, or
image by calling a caller-supplied generator
function. shinyseo does not integrate with any particular LLM or
image-generation service itself – generator is the caller’s
own function, written against whatever API they already have access to
(OpenAI, Adobe Firefly, a local model, and so on). This keeps the
package free of any vendor dependency, API key, or running cost of its
own.read_meta() (used internally by
social_meta(), write_manifest(), and
init_meta()) now decodes the YAML file as raw UTF-8 bytes
instead of going through yaml::read_yaml()’s
readLines()-based reader. Under a non-UTF-8 locale
(LC_CTYPE=C, common on minimal servers/CI runners), the old
reader silently stopped at the first non-ASCII character (e.g. Norwegian
“æøå”), dropping every field after it with no warning or error.init_meta() now reads an existing meta file (if any)
and shows its current values as defaults for each prompt, so pressing
Enter keeps what’s already there instead of clearing it.First stable release. The API (social_meta(),
update_meta(), write_manifest(),
init_meta(), and the meta field names) is now
considered stable.
init_meta(path) — interactively answer a few
questions at the console and write the result to a meta.yml
file, so new users can get started without reading the field reference
first.
update_meta(session, title, description, url, image)
— update metadata reactively from the server without a page reload.
Useful for multi-tab and multi-route apps. social_meta()
now injects the JavaScript handler automatically; no extra setup
required.
write_manifest(meta, path, display, start_url, background_color)
— generate a www/manifest.json web app manifest from the
same metadata object used by social_meta(). Call once in
global.R.
Favicon and PWA fields in social_meta():
favicon + favicon_type →
<link rel="icon"> with automatic MIME type detection
from file extensionapple_touch_icon →
<link rel="apple-touch-icon">manifest →
<link rel="manifest">theme_color →
<meta name="theme-color">short_name → used by write_manifest() for
the manifest short_nameapple_mobile_web_app_capable →
<meta name="apple-mobile-web-app-capable"> and
<meta name="mobile-web-app-capable">, so the app runs
standalone when added to a phone’s home screenapple_mobile_web_app_title →
<meta name="apple-mobile-web-app-title">apple_mobile_web_app_status_bar_style →
<meta name="apple-mobile-web-app-status-bar-style">Custom meta tags via the custom field — a list of
lists where each inner list’s keys map directly to HTML attributes on a
<meta> tag. Supports both name= and
property= style tags.
