Projects

  • A microformats2 parser, written in C (utilizing gumbo-parser for HTML parsing). Will most likely be open-sourced one day. A day when I don't care about how ugly the code is.
  • https://joskar.se -- my personal website. Mostly written in Bourne Shell (/bin/sh) and C (see above).

Working On

"Identity transform" for MF2/HTML

A way to do an "identity transform" on my MF2/HTML-pages. Currently I'm losing some meta-data when editing pages using my CMS. This will also help when I want to add data (such as webmentions) to an existing page.

Webmention support

Currently one can send webmentions to my webmention endpoint, and they will be validated (asynchronously). The webmentions will not show up anywhere since I need to solve the above task first ("Identity transform").

Microformats2 parser

  • The above-mentioned mf2 parser. It is almost feature-complete now, except for backwards compatibility with the older microformats. It will most likely be open-sourced some day.
  • I am also working on a tool for extracting MF2 from the command-line (I am coding my website in /bin/sh after all...), aptly codenamed `mfget' (for now). It is simplistic by design, and it can currently do these things:
    • Get a value (or several) from the parse-tree: mfget <file.html /items/entry/name [...]
    • Encode the values in hexadecimal: mfget <file.html x/items/entry/name (This way it is easier to use `cut' and other command-line tools without worrying.)
    • Iterate over one arbitrary parameter: mfget <file.html /items/entry[]/name

Content Management System

I have built a "simple" CMS using a sort of templating system. The templates are basically HTML files with some shell script sprinkled throughout. The "identity transform" described above is a milestone in this project, which I have yet to complete.

Itches

DRY

I am trying to operate on the data already stored in my MF2/HTML as much as possible. See the "Identity transform" section above.

  • I don't have any explicit links to alternate pages or syndication in the <body> of my pages. I do however use CSS to show the <link>-elements which are residing in <head>. This is because most crawlers only look for rel="alternate" in head, and putting the same link in <body> for the sake of navigation would be a violation of DRY.
    • As a side note, text browsers such as lynx already show <link> elements in <head> if they have a title-attribute set. Why modern graphical browsers don't allow this by default is beyond me.

Bilingual support

For some reason I thought it would be cool to have bilingual support on my website. Perhaps mostly because I thought it would be silly to host primarily English content on a Swedish ccTLD (.se). Obviously communication with the Indieweb community will mostly be English, so that leaves me with no choice. Who knows, if I keep using a frontpage with an obscure language then perhaps people will be more willing to code in language detection on their websites as well :)

  • All translated pages on my website have the lang-attribute set on the html tag, and a link to a translation with rel="alternate", hreflang="...", and href="..." set.

POSSEing to (unsupported)

I am not a big "blogger", but I do like movies. So I want to POSSE some small thoughts I have on the subject of film to some film-reviewing silo, such as MUBI. I already have an account there, so I might just as well try to incorporate support for it.

  • On 2014-10-16, I managed to import all of my "reviews" from MUBI to my site using their (unfortunately undocumented) snowflake API.

Things I am thinking about, but don't care enough to ask (for now)

  • Why does reply-context suggest using a p-in-reply-to instead of u-in-reply-to? I thought the in-reply-to was supposed to be a URL?
    • The prefix indicates to the parser where to find the value. If the value is in an href attribute, then you'd use "u-". If the value is plain text or a nested mf2 object, you'd use the "p-" prefix. Aaron Parecki 14:42, 22 October 2014 (PDT)
    • Also, it seems like its conjunction with h-cite is important. But when parsed, wont the in-reply-to and h-cite become siblings in the parse-tree? Then they are not inherently related...
