Day 3: relative urls

Today I started with fiddling with reply-contexts, but that turned out to be a giant mess, because I store my own posts in a different format than posts by others, and I wanted to re-use my template. I need to come back to that another time.

Yesterday, I mentioned Martijn in my post. And when I mention urls in my posts, my server will try to notify the other site that I mentioned that page. So yesterday my site notified Martijn’s site. At least, it tried.

Martijn is known for giving parsers a hard time. My site came up with as his webmention endpoint, which is not correct. The following things went wrong:

  • I mentioned, which is not his canonical url. That’s, ending in a /.
  • Kirby Toolkit’s remote::get(), which I used to fetch the page, did follow the redirect, but my script didn’t update the mentioned url accordingly. Since Martijns endpoint link is relative (webmention.php), that / does matter: it defines Martijns page as a folder, so his endpoint is at
  • Finally, it turned out that Kirby Toolkit’s url::makeAbsolute($path, $home) did not handle relative urls well. It just intelligently added $path to $home, but didn’t actually solve relative urls where $home is a folder or file.

Martijn encouraged me to write some tests for Kirby Toolkit, because they use phpunit and all that stuff. It was nice, because I didn’t have any experience with this kind of testing (I just refresh the page and hope it works). Learning to test things is a goal for 2017 for me.

When I had a list of good tests, I started to change the function. I might be a little too refresh-frenzy still, but in the end I managed to pass all my own tests. After the pull request and with a little tweaking of my own scripts, I finally got Martijn’s endpoint:

So, Martijn, here is another try, still without your canonical /, just to see if it works now. :)
