Hugo: Count entries in Taxonomy

For the "PostgreSQL Person of the Week" interviews I'm using Hugo as static blogging engine. Part of every interview is the list of tags, which links this interview to other similar interviews. However until recently no one really knew if a tag is popular or just used in this interview. I wanted to change this, and add the tag count behind every tag.

The way I use Hugo I have the previews also online, and I don't want to count any interviews which are not published (still drafted) when counting entries for a tag.

Tags in Hugo are taxonomies, which is a user-defined grouping of content.

Avoid linebreaks in Hugo shortcodes

Shortcodes in Hugo are a neat and poweful system to avoid repating the same piece of text over and over again. Let's say I have the following text:

Nunc in odio id magna molestie congue. Donec erat nulla, pulvinar eget volutpat non, molestie at nisi. Curabitur nec tristique felis. Cras imperdiet, ante et vestibulum iaculis, tellus ipsum pulvinar felis, at viverra est tellus et eros. In nec dignissim lectus, bibendum hendrerit ex. Praesent lobortis eget justo non vehicula.

Nulla et neque cursus libero tristique laoreet nec a ligula. Fusce sit “amet” scelerisque erat. Quisque lorem lectus, lobortis vitae mattis non, tincidunt sed felis. Donec sit “amet” erat nibh.

Orci varius natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. In et imperdiet dui. In ut enim pharetra, blandit purus vel, malesuada est. Morbi sollicitudin eget leo nec dignissim. Praesent sed leo quis purus pretium aliquet sed quis arcu. Pellentesque facilisis tellus nulla, dignissim laoreet quam maximus et.

And I want to link the "amet" word, then I can create a shortcode:

layouts/shortcodes/amet.html

And in this shortcode I place the text:

<a href="https://www.lipsum.com/feed/html">amet</a>

In the Markdown source this is:

Nulla et neque cursus libero tristique laoreet nec a ligula. Fusce sit "{{< amet >}}" scelerisque erat. Quisque lorem lectus, lobortis vitae mattis non, tincidunt sed felis. Donec sit "{{< amet >}}" erat nibh.

Pretty easy. However Hugo by default does a little bit too much: while generating the static content, it adds a line break. Which in the browser results in:

Nulla et neque cursus libero tristique laoreet nec a ligula. Fusce sit “amet ” scelerisque erat. Quisque lorem lectus, lobortis vitae mattis non, tincidunt sed felis. Donec sit “amet ” erat nibh.
                                                                            ^                                                                                                         ^

There is a nasty little space between the word and the quotation mark. The generated HTML source shows the problem:

  <p>Nunc in odio id magna molestie congue. Donec erat nulla, pulvinar eget volutpat non, molestie at nisi. Curabitur nec tristique felis. Cras imperdiet, ante et vestibulum iaculis, tellus ipsum pulvinar felis, at viverra est tellus et eros. In nec dignissim lectus, bibendum hendrerit ex. Praesent lobortis eget justo non vehicula.</p>
<p>Nulla et neque cursus libero tristique laoreet nec a ligula. Fusce sit &ldquo;<a href="https://www.lipsum.com/feed/html">amet</a>
&rdquo; scelerisque erat. Quisque lorem lectus, lobortis vitae mattis non, tincidunt sed felis. Donec sit &ldquo;<a href="https://www.lipsum.com/feed/html">amet</a>
&rdquo; erat nibh.</p>

Usually a line break in HTML is not a big deal, the browsers deal with that. But here an unnecessary space is added while rendering the content. Hugo makes it complicated to avoid this problem. There is no default setting to turn this off, however the shortcode can have an extra Hugo tag to avoid the training linebreak:

<a href="https://www.lipsum.com/feed/html">amet</a>{{- / Strip trailing newline. / -}}

By adding the {{- -}}, the training line break is not included in the final HTML output, and the quotation mark comes right after the shortcode content.

Huginn: Filter Retweets

A while ago I started using Huginn, as a replacement for IFTTT. That's going quite well. Huginn offers more features, integrations, and especially your chains (scenarios) can be as complex as you wish. IFTTT is quite limited in this area.

I use the Twitter integration to find certain Tweets. Now this does not only find native Tweets, but also finds every Retweet made for a native Tweet. Obviously I am not interested in duplicate content.

Huginn offers a way to filter out Retweets.

Public previews in Hugo

Hugo is a static templating system. It is (mainly) used to deploy websites/blogs which don't have and need dynamic content. The content of all pages is pre-generated, and the webserver delivers files from disk (or rather from cache, once files are loaded into memory). This approach allows for extremely fast websites, as no dynamic content is generated on every request.

While I know Hugo from work, I haven't really used it for private projects - until recently. I have started a new project where I present interviews with people behind the PostgreSQL Project - and this is perfect for a static website. Interviews don't change, once published.


There was just a little problem: every interview must be approved by the interviewed person. This requires a full preview, but one which does not show up on the main website, or the Sitemap, or the RSS feed. By default, even drafts show up in Sitemap and the RSS feed in Hugo.

Stöckchen gefangen

Es gibt wieder tiefliegende Stöckchen, diesmal von Stefan, mit drei lustigen Fragen:


1. Wenn Du eine beliebige Person sein könntest, für wen würdest Du Dich entscheiden?


Für mich. Ich halte nichts davon, anderen Leuten nachzueifern oder wie jemand anderes zu sein. Lebe lieber mein eigenes Leben ;-)


2. Welchen Kinofolm hättest Du am liebsten nie gesehen?


Schwere Entscheidung, so etwas verdränge ich und denke nicht mehr drüber nach. Aber "Crank" war grottenschlecht, würde ich mir kein zweites Mal anschauen wollen.


3. Welches Getränk wärst du?


Cappuccino.


Weil es so schön ist, werfe ich mal weiter in Richtung Haribo, Kilzi und akretschmer.

Fünf Dinge, die ich schon immer mal ausplaudern wollte

depesz hat mir da ein Stöckchen zugeworfen, auch wenn er es auf Polnisch verfasst hat. Also hier sind 5 Neuigkeiten über mich, sollte hoffentlich noch niemand so genau wissen:

  1. Eis ist nicht alles im Leben. Aber es macht trotzdem glücklich.
  2. Keyboard wollte ich immer spielen können, aber leider bin ich total unmusikalisch.
  3. Ich war jahrelang sauer, das mir damals in der Schule der Computerclub weggenommen wurde. *Grummel* Wann hat man als Schüler schon mal die Chance, eine Arbeitsgemeinschaft zu leiten?
  4. Bin viel zu faul, eine weitere Fremdsprache zu lernen, weil eigentlich sollte ich mir das mal antun.
  5. Ich mag zwar Auto fahren, aber irgendeine passende Beschäftigung braucht man dabei, das wird sonst viel zu langweilig.
Dann werfen wir das ganze mal weiter zu: Haribo, alita, formorer, kilzi bekommt einen Grund, sein Blog besser zu pflegen und wer sich sonst noch angesprochen fühlt, darf auch fangen.
