About

A Hugo module / theme component that adds partials and a shortcode for displaying most variables available on pages generated by Hugo. See License for permissions for use.

REOPENED: Based on a request this repo does seem to be useful to some as a tool for learning some of Hugo's internal state for pages/sites, so I have reopened it to submissions and activity. It's getting a little bit if updating, bt mostly I don't need it for myself, so improvement will mostly occur based on input from those who let me know via Pull Requests, Discussions, or Issues (as appropriate).

Modern Hugo only (as of 2021-03-20)

This module is built using assumptions that may require Hugo 0.80.0 or higher, and in any event those are the only versions on which it has been tested, at present.

Note: Previously the minimium was 0.81.0 but as of 2022-07-12 we have converted from multi-line constructs (like dict) to single line as that is the difference between supporting 0.80.0 (which is the highest version available in Debian stable, and various other Linux releases) and requiring at least 0.81.0.

Using in Your theme or site

Full set of tables

As a partial in layouts

To use the full list of available debug tables as a partial in your layouts, simply add:

{{ partial "helpers/debug-tables/debug-tables-list" . }}

in the layout(s) used for the page(s) on which want the tables to appear.

As a shortcode in a content page

To use the full list of available debug tables as a shortcode on a page in your content pages, simply add:

{{</* helpers/hugo-debug-tables */>}}

to the page on which you want the table, under your site's content/ directory.

NOTE: This will only work if the content page in question actually gets rendered. (Many section layouts, for instance, do not render .Content and therefore this shortcode would not work with those layouts).

Using individual tables

As a partial

Each of the tables (page, section, file, site, taxonomy, hugo, os-stat) expects the same context: a dictionary (dict) with following keys:

  • Page
  • basePage
  • Site
  • baseSite

So, for example to emit the site table, one would use:

{{ partial "helpers/debug-tables/tables/site" (dict "Site" site "baseSite" $baseSite "Page" $curPage "basePage" $basePage }}

As a shortcode

E.g.

{{</* helpers/hugo-debug-tables table="site" */>}}

Where 'site' is one of page, section, file, site, taxonomy, hugo, os-stat.

Note that for the shortcode, only .RawContent renders, not .Content, .Plain, or other rendered content for the current page (in the table produced by the shortcode).

Adding the code to your site or theme

  1. Get a copy of the code for, and switch to the directory for your site or theme.

Using Hugo modules (preferred)

  1. Initialize the Hugo module system: hugo mod init github.com/<your_user>/<your_project> (assuming you are using github, of course).

  2. Import hugo-debug-tables in your config.toml

    [module]
      [[module.imports]]
         path = "github.com/danielfdickinson/hugo-debug-tables"
  3. Change back to the site directory

  4. Get the module

    hugo mod get github.com/danielfdickinson/hugo-debug-tables
  5. Add the code (above) for using the tables to your source code.

Using downloaded copy of the module (e.g. zip from the git repo)

  1. Obtain a copy of the module e.g. (a module Zip file from the Git repo)
  2. Copy/extract the files in the archive into the root of your site or theme (archives contain /layouts and subdirectories under it).
  3. Change back to the site directory

Run the Hugo server

  1. To test the result, run the local Hugo server (assumes you have a theme or layouts in your site)

    hugo server -b http://localhost:1313/

Current default is for debug tables only added for "development"

The code is currently designed to only add the debug tables if running Hugo in "development" mode. That means it will, by default, be added when using hugo server but not a regular build with hugo (and only if you call the partial or shortcode, of course).

Change debug table from development only

To use for both development and production builds

In config.toml add

[params]
     debugTableEnvironment = ["development","production"]

To never include in builds

[params]
     debugTableEnvironment = [""]

NB The "" is required because an empty slice (or no param) defaults to ["development"]

You can also use custom environments

In config.toml add

[params]
     debugTableEnvironment = ["custom1","custom2"]

And of course if you wanted you could add "development" and/or "production"

Test CSS styling

A test CSS file is available in assets/css/hugo-debug-tables/debug-demo.css. To use it place a line such as the following:

{{- partial "helpers/debug-tables/debug-head-snippet" . -}}

in the <head> section of your layout(s).

Note that this partial adds the above CSS as a resource to a variable $addToCSS (which must be defined prior to the partial). It assumed that $addToCSS is processed by Hugo Pipes in order to include the above CSS in the output CSS. If that is not what you want, you may handle the CSS file yourself using Hugo Pipes.

A note on navigation

Details (disclosure elements) embedded inside a another table create a new layer above the current table when opened. To get rid of the new layer and close the table, close the details (disclosure) element that appears above the table or other disclosure content.

CSS classes available for styling the debug tables

Two types of classes available:

  • Element classes (e.g. details-debug-hugo)
    • By actual use of element not the HTML element type (e.g. details, list, table-cell) — sometimes an <li> might be used with details when there is no additional information, but the item is a part of a list of details.
    • May include a hyphen in the element type part
      • Always end in -debug-hugo to denote they are 'debug table' classes
  • Category/Purpose Classes
    • E.g. debug-pages-hugo which is wrapped around HTML for page lists/tables
    • Always begin with debug and end in hugo. The middle is a single word (no hyphens).

Element classes

Class Description
code-debug-hugo Added to any element intended to show source code or content (as source)
details-debug-hugo Added to any element that can contain additional details with a disclosure widget
