For each fancy podcast episode, write a blog post containing - `\[[!meta enclosure="WikiLink/to/media.mp3"]]`. (Don't specify - more than one enclosure -- but if you do, last one wins.) -7. When rendering to HTML (single-page or inlined), append a link - to the media file. -7. When rendering to RSS/Atom, the text is the entry's content and - the media file is its enclosure. -7. Don't break simple podcasts in pursuit of fancy podcasts. - -## Implementation - -### Completed - -* Cover the existing simple podcast behavior with tests. -* Add an `enclosure` field to [[plugins/meta]] that expands the - given [[ikiwiki/WikiLink]] to an absolute URL (feed enclosures - pretty much need to be, and the reference feeds I've looked at - all do this). -* Write failing tests for the desired single-page and inlined - HTML behavior, then make them pass by adding enclosure stanzas - to `{,inline}page.tmpl`. -* Write failing tests for the desired RSS/Atom behavior, then make - them pass via changes to `{atom,rss}item.tmpl` and [[plugins/inline]]. -* Match feature-for-feature with - [tru_podcast](http://www.rainskit.com/blog/542/tru_podcast-a-podcasting-plugin-for-textpattern) - (what [[schmonz]] will be migrating from). -* Enrich [feed metadata](http://cyber.law.harvard.edu/rss/rss.html) - by catching up `rsspage.tmpl` to `atompage.tmpl`. -* Verify that [[plugins/more]] plays well with fancy podcasts. -* Verify that the feeds validate. -* Subscribe to a fancy feed in some common podcatchers and verify - display details against a reference podcast. -* Verify smooth transitions for two common use cases (see testing - details below). - -### Must-have (for [[schmonz]], anyway) - -* Think carefully about UTF-8. -* Verify that _all_ the tests pass (not just my new ones). - -## Migration - -### Upgrading within ikiwiki: from simple to fancy - -#### My test podcast - -For this test, I chose a podcast that tries to work around ikiwiki's -current limitations by issuing two separate `inline`s: - -* One with `feedonly=yes` that includes `.mdwn`, `.pdf`, and `.mp3` -* One with `feeds=no` that includes only `.mdwn` (and makes a trail) - -This has the following effects: - -* Browser: sees just the articles (each of which has a manually - created link to its corresponding media file) -* Feedreader: sees all the articles and media in one flat stream -* Podcatcher: sees just the media (sans articles) - -I want instead to write one `inline` with these effects: - -* Browser: sees just the articles (each of which automatically links - to its enclosure) -* Feedreader: sees just the articles (each of which specifies its - enclosure) -* Podcatcher: sees just the enclosures (each of which has an enclosing - article, rendered as the media's "description") - -#### Upgrade steps - -7. Set up a non-production copy of the podcast. - 7. Visually diff RSS and Atom feeds against production. - 7. Subscribe to the copy (both feeds) in `r2e`, iTunes, Downcast. -7. Apply fancypodcast patch to the installed ikiwiki: - 7. `cd ~/Documents/trees/ikiwiki && git checkout fancypodcast` - 7. `git diff --no-prefix master > ~/Documents/trees/localpatches/www/ikiwiki/fancypodcast.diff` - 7. `cd ~/Documents/trees/pkgsrc-current/www/ikiwiki && make deinstall && make install clean` -7. Verify that simple podcasts are unaffected: - 7. Rerun `ikiwiki --setup`. - 7. `diff -uB simple-before.rss simple-after.rss` - * A few new elements and attributes, as expected. - 7. `diff -uB simple-before.atom simple-after.atom` - * No change. -7. Remove the feed-only `inline` and enable feeds on the remaining one. -7. Convert articles' manual download links to `\[[!meta enclosure=""]]`. -7. I want existing and future podcatchers to get my new fancy - episodes, and I know my podcast isn't in any planets, so I'm - going to skip [[tips/howto avoid flooding aggregators]]. -7. Rerun `ikiwiki --setup`. -7. Verify browser shows the same stuff. -7. `diff -uB simple-after.rss fancy-after.rss # and atom` - * MP3s and PDFs are no longer naked enclosures, but belong to - articles as they should. - * Articles have updated modification times, as they should. -7. `r2e run` (both RSS and Atom) - * Nothing new with the default `trust-guid = True` (otherwise - would expect updated articles). -7. iTunes "Update Podcast" (both RSS and Atom) - * Added one episode per article, with article text as the episode - description. - * Kept old naked-enclosure episodes around. -7. Downcast refresh (RSS): - * Added one episode per article, with article text as the episode - description. - * Kept old naked-enclosure episodes around. -7. Downcast refresh (Atom): - * Added one episode per article, with no episode description - (expected, see feature table). - * Kept old naked-enclosure episodes around. - -Different tradeoffs are possible. These seem okay to me. - -### Importing into ikiwiki: fancy (from another CMS) - -#### My test podcast - -For this test, I chose a podcast currently being published with -Textpattern and tru_podcast, because I'd strongly prefer to publish -it with ikiwiki instead. - -#### Upgrade steps - -7. Set up a non-production copy of the podcast. - 7. Visually diff RSS and Atom feeds against production. - 7. Subscribe to the copy (both feeds) in `r2e`, iTunes, Downcast. -7. With a fancypodcast-enabled ikiwiki installed: - 7. Copy content from Textpattern to ikiwiki: - 7. Match article paths to preserve `/YYYY/MM/DD/post-title` permalinks. - 7. Match enclosure paths (or redirect) to preserve Textpattern's URLs. - 7. Match titles, post dates, and guids with `\[[!meta]]`. - 7. Match feed paths with permanent redirects from `/atom/` to - `/index.atom` (and same for RSS). - 7. `\[[!inline]]` the articles. - 7. Rerun `ikiwiki --setup`. -7. Stop Textpattern, start ikiwiki. -7. Verify that podcatchers see the feeds and don't redownload anything. -7. Naively add two new blog posts, one with an enclosure. -7. Verify that podcatchers download the new enclosures. +## Future improvements ------ +### Embedded audio/video player in browsers -## Future improvements +* For a given enclosure, depending on autodetected MIME: + * `audio/*` -> `
