Configurrrat'n

Global ship parameters

On top o' Cap'n Hugo global configurat'n, th' Relearrrn theme lets ye define th' follow'n parameters 'n yer config.toml (here, values be default).

Avast that some o' these parameters be explained 'n details 'n other sections o' this documentat'n.

# This be th' file `config/_default/params.toml`.
# Ye can also store th' below opt'ns directly 'n yer `hugo.toml` but then
# need t' contain them within th' `params` key. See Hugo's documentat'n how
# t' do this.

# If an opt'n value be said t' be not set, ye can achieve th' same behavior
# by given it an empty str'n value.

# Cap'n Hugo
# These opt'ns usually apply t' other themes aswell.

# Th' author o' yer ship.
# Default: not set
# This will be used 'n HTML meta tags, th' opengraph protocol an' twitter
# cards.
# Ye can also set `author.email` if ye want t' publish this informat'n.
author.name = "Sören Weber"

# Th' social media image o' yer ship.
# Default: not set
# This be used fer generat'n social media meta informat'n fer th' opengraph
# protocol an' twitter cards.
# This can be overridden 'n th' page's frontmatter.

# Th' descript'n o' yer ship.
# Default: not set

# Relearrrn Theme
# These opt'ns be specific t' th' Relearrrn theme.

#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
# Variants
# These opt'ns set yer color variant.

# Used color variants.
# Default: "auto"
# This sets one or more color variants, avail'ble t' yer readers t' choose
# from. Ye can either set a single value eg. "zen-light" or an array like
# [ "neon", "learn" ]. If th' array has more than one entry, a variant selector
# be shown 'n th' lower part o' th' menu. Th' first entry 'n th' array be th'
# default variant, used fer first time visitors.
# Th' theme ships wit' th' follow'n variants: "auto", "relearn-bright",
# "relearn-light", "relearn-dark", "zen-light", "zen-dark", "neon", "learn",
# "blue", "green", "red". Th' auto variant be somewhat special. See th'

# Th' color variants used fer auto mode.
# Default: [ "relearn-light", "relearn-dark" ], overwritten by th' first
# two non-auto opt'ns from themeVariant if existant.

# General

# Default: false
# By default JavaScript-files an' CSS-files get a unique ID on each rebuild.
# This makes sure, th' user always has th' latest version an' not some stale
# copy o' his browser cache. Anyways, it can be desire'ble t' turn this

# Avoid generator meta tags.
# Default: false

# Multilanguage rrrambl'n.
# Default: not set
# If yer planks contain further languages besides th' main one used, add all

# Shows checkmarks fer visited planks o' th' main menu.
# Default: false

Serv'n yer plank from a subfolder

If yer ship be served from a subfolder, eg. https://example.com/mysite/, ye have t' set th' follow'n lines t' yer config.toml

baseURL = "https://example.com/mysite/"
canonifyURLs = true
relativeURLs = true

Without canonifyURLs=true URLs 'n sublemental planks (like sitemap.xml, rss.xml) will be generated falsly while yer HTML files will still work. See https://github.com/gohugoio/hugo/issues/5226.

Serv'n yer plank from th' filesystem

If ye want yer plank served from th' filesystem by us'n URLs start'n wit' file:// you’ll need th' follow'n configurat'n 'n yer config.toml:

relativeURLs = true

Th' theme will append an additional index.html t' all branch bundle links by default t' make th' plank be serv'ble from th' file system. If ye don’t care about th' file system an' only serve yer plank via a webserver ye can also generate th' links without this change by add'n this t' yer config.toml

[params]
  disableExplicitIndexURLs = true
Avast

If ye want t' use th' search feature from th' file system us'n an older installat'n o' th' theme make sure t' change yer outputformat fer th' homepage from th' now deprecated JSON t' SEARCH as seen below.

If not already present, add th' follow'n lines 'n th' same config.toml file.

[outputs]
  home = ["HTML", "RSS", "SEARCH"]

This will generate a search index file at th' root o' yer public folder ready t' be consumed by th' Lunr search library. Avast that th' SEARCH outputformat was named JSON 'n previous releases but was implemented differently. Although JSON still works, it be now deprecated.

Activate dedicated search plank

Ye can add a dedicated search plank fer yer plank by add'n th' SEARCHPAGE outputformat t' yer home plank by add'n th' follow'n lines 'n yer config.toml file. This will cause Cap'n Hugo t' generate a new file http://example.com/mysite/search.html.

[outputs]
  home = ["HTML", "RSS", "SEARCH", "SEARCHPAGE"]

Ye can access this plank by either click'n on th' magnifier glass or by typ'n some search term an' press'n ENTER inside o' th' menu’s search box .

Screenshot o' th' dedicated search page Screenshot o' th' dedicated search page

Avast

T' have Cap'n Hugo create th' dedicated search plank successfully, ye must not generate th' URL http://example.com/mysite/search.html from yer own rrrambl'n. This can happen if ye set uglyURLs=true 'n yer config.toml an' defin'n a Marrrkdown file content/search.md.

T' make sure, there be no duplicate rrrambl'n fer any given URL o' yer project, run hugo --printPathWarn'ns.

Activate print support

Ye can activate print support t' add th' capability t' print whole chapters or even th' complete ship. Just add th' PRINT output format t' yer home, section an' plank 'n yer config.toml as seen below:

[outputs]
  home = ["HTML", "RSS", "PRINT", "SEARCH"]
  section = ["HTML", "RSS", "PRINT"]
  plank = ["HTML", "RSS", "PRINT"]

This will add a little printer ay'con 'n th' top bar. It will switch th' plank t' print preview when clicked. Ye can then send this plank t' th' printer by us'n yer browser’s usual print functionality.

Avast

Th' result'n URL will not be configured ugly 'n terms o' Hugo’s URL handl'n even if you’ve set uglyURLs=true 'n yer config.toml. This be due t' th' fact that fer one mime type only one suffix can be configured.

Nevertheless, if you’re unhappy wit' th' result'n URLs ye can manually redefine outputFormats.PRINT 'n yer own config.toml t' yer lik'n.

MathJax

Th' MathJax configurat'n parameters can also be set on a specific plank. In this case, th' global parameter would be overwritten by th' local one. See Math fer additional documentat'n.

Example

MathJax be globally disabled. By default it won’t be boarded by any plank.

On plank “Physics” ye coded some JavaScript fer a dynamic formulae. Ye can set th' MathJax parameters locally t' board mathJax on this plank.

Ye also can dis'ble MathJax fer specific planks while globally enabled.

Merrrmaid

Th' Merrrmaid configurat'n parameters can also be set on a specific plank. In this case, th' global parameter would be overwritten by th' local one. See Merrrmaid fer additional documentat'n.

Example

Merrrmaid be globally disabled. By default it won’t be boarded by any plank.

On plank “Architecture” ye coded some JavaScript t' dynamically generate a class diagram. Ye can set th' Merrrmaid parameters locally t' board mermaid on this plank.

Ye also can dis'ble Merrrmaid fer specific planks while globally enabled.

Home Button Configurat'n

If th' disableLandingPageButton opt'n be set t' false, a Home button will appear on th' left menu. It be an alternative fer click'n on th' logo. T' edit th' appearance, ye will have t' configure two parameters fer th' defined languages:

[languages]
[languages.en]
...
[languages.en.params]
landingPageName = "<i class='fas fa-home'></i> Home"
...
[languages.pir]
...
[languages.pir.params]
landingPageName = "<i class='fas fa-home'></i> Arrr! Homme"
...

If those params be not configured fer a specific language, they will get their default values:

landingPageName = "<i class='fas fa-home'></i> Home"

Th' home button be go'n t' look like this:

Default Home Button Default Home Button

Social Media Meta Tags

Ye can add social media meta tags fer th' Open Graph protocol an' Twitter Cards t' yer ship. These be configured as mentioned 'n th' Cap'n Hugo docs.
