Using pipe for Function Pipeline

We can use the | operator to compose multiple functions for Function Pipeline.

Version

Hugo 0.91

Page Variable

content/_index.md

---
title: my **blog**
---

title : use Markdown to define page variable

Pipe

layouts/index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <script src="alpine.js" defer></script>
    <link rel="stylesheet" href="output.css" />
  </head>
  <body>
    <h1 class="text-4xl text-red-500">{{ .Title | humanize | markdownify }}</h1>
  </body>
</html>

Line 10

<h1 class="text-4xl text-red-500">{{ .Title | humanize | markdownify }}</h1>

humanize : return the humanized version of an argument with the first letter capitalized
markdownify : transform Markdown to HTML
| : Function Pipeline from .Title to humanize to markdownify

Conclusion

When using multiple functions on the template, pipes are more readable for the codebase
