C Appendix C. The Go Template Language

The Go Template language is a language specifically designed to fill templates for the Go programming language. Hugo builds upon the Go template language and adds variables and functions to provide additional functionality.

Accessing the Go template language inside of Hugo requires the use of two curly braces {{…}} anywhere within the template file. We already saw some of these in action when we did shortcodes in Chapter 4. Hugo parses the HTML files looking for these template markers and executes the Go template script within these tags. Any HTML outside of these is treated as textual content for the Go template. Each page in Hugo is rendered separately in parallel to others. We can share pieces of rendered content across pages. All pages have access to all other pages via variables.

While we are free to use HTML comments in Hugo templates. In the development mode, these comments are rendered as comments in the generated HTML. They can be stripped off when we minify the generated output but may be annoying in debugging the generated HTML. We can also use Hugo comments which will be present only in the file and will be stripped off while rendering.

If we use a HTML comment to strip out Hugo code, it does not work as the code is still executed. HTML comments are useful for providing instructions content authors and editors and help them resolve issues. Hugo Comments are useful for theme authors.

<!-- A HTML comment. Renders unless stripped off during minify -->

{{/* A Hugo comment. Does not render at all */}}

<!-- Even though its result might be commented but {{.}} is still executed -->

Figure C.1. Error reporting for Hugo templates. When we use erroneous template code in a template, Hugo provides us with the exact line number where things go wrong during rendering.

Let us take an overview of the features of the Go template language which form the building blocks of the website template. The Hugo documentation provides a ready reference of all the possible variables and functions that exist in Hugo. Note that the code resources for this appendix are present as a part of chapter 5 and chapter 6 resources for this book.

C.8.8 Resource Manipulation and Hugo Pipes

Functions like resources.GetMatch allow access to assets files, both for linking and manipulation.

We do not need to know all functions to be successful with Hugo. It is good to keep the function reference (gohugo.io/functions) handy when writing templates. The chances are, if we are trying to do some manipulation, it might be natively available in Hugo.
