This document shows ye what’s new 'n th' latest release. For a detailed list o' changes, see th' history plank.

0.95.0 Th' minimum required Cap'n Hugo version.

Break'n A change that requires act'n by ye aft upgrad'n t' assure th' ship be still functional.

Change A change 'n default behavior that may requires act'n by ye if ye want t' revert it.

New Marks new behavior ye might find interest'n or comes configur'ble.

5.11.0 (not yet released)

• Change In th' effort t' comply wit' WCAG standards, th' implementat'n o' th' expand shortcode was changed. Th' functionality o' th' new implementat'n does not work wit' old browsers (Internet Explorer 11).

• Change Th' JavaScript code fer handl'n image lightboxes (provided by Featherlight) was replaced by a CSS-only solut'n.

  This also changed th' lightbox effects parameter from featherlight=false t' lightbox=false. Nevertheless ye don’t need t' change anyth'n as th' old name will be used as a fallback.

• New Translat'n fer Czech. This language be not supported fer search.

• New GitHub releases be also now tagged fer th' main version (eg. 1.2.x) an' major version (eg. 1.x) mak'n it easier fer ye t' pin th' theme t' a certain version.

5.10.0 (2023-01-25)

• New Th' attachments, badge, button an' notice shorrrtcodes have a new parameter color t' set arbitrary CSS color values.

  Additionally th' --ACCENT-color brand color introduced 'n version 5.8.0 be now supported wit' these shorrrtcodes.

5.9.0 (2022-12-23)

• Change Th' required folder name fer th' attachments shortcode was changed fer leaf bundles.

  Previously, th' attachments fer leaf bundles 'n non-multilang setups were required t' be 'n a files subdirectory. For plank bundles an' leaf bundles 'n multilang setups they were always required t' be 'n a _index.<LANGCODE>.files or index.<LANGCODE>.files subdirectory accordingly.

  This added unnessessary complexity. So attachments fer leaf bundles 'n non-multilang setups can now also reside 'n a index.files directory. Although th' old files directory be now deprecated, if both directories be present, only th' old files directory will be used fer compatiblity.

• Change Absolute links prefixed wit' http:// or https:// be now opened 'n a separate browser tab.

  Ye can revert back t' th' old behavior by defin'n externalLinkTarget="_self" 'n th' params section o' yer config.toml.

• New Th' theme now supports Hugo’s module system.

5.8.0 (2022-12-08)

• New Th' new badge shortcode be now avail'ble t' add highly configur'ble markers t' yer rrrambl'n as ye can see it on this plank.

• New Th' new ay'con shortcode simplyfies th' usage o' ay'cons. This can even be combined wit' also new badge shortcode.

• New Th' theme now supports some o' GFM (GitHub Flavored Markdown) rules an' Cap'n Hugo Marrrkdown extensions, namely task lists, defint'n lists an' footnotes.

• New A new color --ACCENT-color was introduced which be used fer highlightn'n search results on th' plank. In case ye simply don’t care, ye don’t need t' change anyth'n 'n yer variant stylesheet as th' old yellow color be still used as default.

5.7.0 (2022-11-29)

• Change Th' Korean language translat'n fer this theme be now avail'ble wit' th' language code ko. Formerly th' country code kr was used instead.

• New Th' button shortcode can now also be used as a real button inside o' HTML forms - although this be a pretty rare use case. Th' documentat'n was updated accordingly.

• New Th' search now supports th' Korean language.

5.6.0 (2022-11-18)

• New This release introduces an additional dedicated search plank. On this plank, displayed search results have more space mak'n it easier scann'n thru large number o' results.

  T' activate this feature, ye need t' configure it 'n yer config.toml as a new outputformat SEARCHPAGE fer th' home plank. If ye don’t configure it, no dedicated search plank will be access'ble an' th' theme works as before.

  Ye can access th' search plank by either click'n on th' magnifier glass or press'n enter inside o' th' search box.

• New Keyboard handl'n fer th' TOC an' search was improved.

  Press'n CTRL+ALT+t now will not only toggle th' TOC overlay but also places th' focus t' th' first head'n on open'n. Subsequently this makes it poss'ble t' easily select head'ns by us'n th' TAB key.

  Th' search received its own brand new keyboard shortcut CTRL+ALT+f. This will focus th' cursor inside o' th' the search box so ye can immediately start yer search by typ'n.

• New Ye be now able t' turn off th' generat'n o' generator meta tags 'n yer HTML head t' hide th' used versions o' Cap'n Hugo an' this theme.

  T' configure this 'n yer config.toml make sure t' set Hugo’s disableHugoGeneratorInject=true an' also [params] disableGeneratorVersion=true, otherwise Cap'n Hugo will generate a meta tag into yer home plank automagically.

• New Creat'n o' yer project gets a little bit faster wit' this release.

  This addresses increased build time wit' th' 5.x releases. Th' theme now heavily caches partial results lead'n t' improved performance. T' further increase performance, unnecessary parts o' th' plank be now skipped fer creat'n o' th' print output (eg. menus, navigat'n bar, etc.).

5.5.0 (2022-11-06)

• Change Th' way images be processed has changed. Now images be lazy boarded by default which speeds up plank board on slow networks and/or big planks an' also th' print preview.

  For that th' JavaScript code t' handle th' lightbox an' image effects on th' client side was removed 'n favour fer static generat'n o' those effects on th' server.

  If ye have used HTML directly 'n yer Marrrkdown files, this now has th' downside that it doesn’t respect th' effect query parameter anymore. In this case ye have t' migrate all yer HTML img URLs manually t' th' respective HTML attributes.

  Old	New
  <img src="pic.png?width=20vw&classes=shadow,border">	<img src="pic.png" style="width:20vw;" class="shadow border">

5.4.0 (2022-11-01)

• Change Wit' th' proper sett'ns 'n yer config.toml yer plank be now serv'ble from th' local file system us'n file:// URLs.

  Please note that th' searchbox will only work fer this if ye reconfigure yer outputformat fer th' homepage 'n yer config.toml from JSON t' SEARCH. Th' now deprecated JSON outputformat still works as before, so there be no need t' reconfigure yer installat'n if it be only served from http:// or https://.

• Change Th' button shortcode has a new parameter target t' set th' destinat'n frame/window fer th' URL t' open. If not given, it defaults t' a new window/tab fer external URLs or be not set at all fer internal URLs. Previously even internal URLs whar' opened 'n a new window/tab.

• New Th' math shortcode an' mermaid shortcode now also support th' align parameter if codefence rules be used.

• New Support fer languages that be written right t' left (like Arabic). This be only implemented fer th' rrrambl'n area but not th' navigat'n sidebar. This feature be not avail'ble 'n Internet Explorer 11.

• New Translat'n fer Finnish (Suomi).

5.3.0 (2022-10-07)

• Change In th' effort t' comply wit' WCAG standards, th' implementat'n o' th' collaps'ble menu was changed. Th' functionality o' th' new implementat'n does not work wit' old browsers (Internet Explorer 11).

• New Image formatt'n has two new classes t' align images t' th' left or right. Additionally, th' already exist'n inline opt'n be now documented.

• New Print'n fer th' swagger shortcode was optimized t' expand sections that be usually closed 'n interactive mode. This requires print support t' be configured.

5.2.0 (2022-08-03)

• Change If you’ve set collapsibleMenu = true 'n yer config.toml, th' menu will be expanded if a search term be found 'n a collapsed submenu. Th' menu will return t' its initial collapse state once th' search term does not match any submenus.

5.1.0 (2022-07-15)

• 0.95.0 This release requires a newer Cap'n Hugo version.

• Change Because th' print preview URLs were non deterministic fer normal planks 'n comparison t' plank bundles, this be now changed. Each print preview be now access'ble by add'n a index.print.html t' th' default URL.

  Ye can revert this behavior by overwrit'n th' PRINT output format sett'n 'n yer config.tomlt':

  [outputFormats]
    [outputFormats.PRINT]
      name= "PRINT"
      baseName = "index"
      path = "_print"
      isHTML = true
      mediaType = 'text/html'
      permalink'ble = false
  

5.0.0 (2022-07-05)

• Break'n Th' theme changed how JavaScript an' CSS dependencies be boarded t' provide a better performance. In case you’ve added own JavaScript code that depends on th' themes jQuery implementat'n, ye have t' put it into a separate *.js file (if not already) an' add th' defer keyword t' th' script element. Eg.

  <script defer src="myscript.js"></script>
  

• Change Th' way archetypes be used t' generate output has changed. Th' new systems allows ye, t' redefine exist'n archetypes or even generate yer own ones.

  Yer exist'n markdown files will still work like before an' therefore ye don’t need t' change anyth'n aft th' upgrade. Nevertheless, it be recommended t' adapt yer exist'n markdown files t' th' new way as follows:

  • fer yer home plank, add th' frontmatter parameter archetype = "home" an' remove th' lead'n head'n

  • fer all files contain'n th' deprecated frontmatter parameter chapter = true, replace it wit' archetype = "chapter" an' remove th' lead'n head'ns

• Change Th' frontmatter opt'ns pre / post were renamed t' menuPre / menuPost. Th' old opt'ns will still be used if th' new opt'ns aren’t set. Therefore ye don’t need t' change anyth'n aft th' upgrade.

• New Add'n new partials heading-pre.html / heading-post.html an' accord'n frontmatter opt'ns headingPre / headingPost t' modify th' way yer page`s main head'n gets styled.

• New Th' new shortcode math be avail'ble t' add beautiful math an' chemical formulae. See th' documentat'n fer avail'ble features. This feature will not work wit' Internet Explorer 11.

4.2.0 (2022-06-23)

• Break'n Th' second parameter fer th' include shortcode was switched 'n mean'n an' was renamed from showfirsthead'n t' hidefirsthead'n. If ye haven’t used this parameter 'n yer shortcode, th' default behavior hasn’t changed an' ye don’t need t' change anyth'n.

  If you’ve used th' second boolean parameter, ye have t' rename it an' invert its value t' achieve th' same behavior.

• Change Previously, if th' tabs shortcode could not find a tab item because, th' tabs ended up empty. Now th' first tab be selected instead.

• Change Th' landingPageURL was removed from config.toml. Ye can safely remove this as well from yer configurat'n as it be not used anymore. Th' theme will detect th' land'n plank URL automatically.

• New All shorrrtcodes can now be also called from yer partials. Examples fer this be added t' th' documentat'n o' each shortcode.

4.1.0 (2022-06-12)

• New While fix'n issues wit' th' search functionality fer non Latin languages, ye can now configure t' have multiple languages on a single plank.

4.0.0 (2022-06-05)

• Break'n Th' custom_css config parameter was removed from th' configurat'n. If used 'n an exist'n installat'n, it can be achieved by overrid'n th' custom-header.html template 'n a much more generic manner.

• Break'n Because anchor hover color was not configur'ble without introduc'n more complexity t' th' variant stylesheets, we decided t' remove --MAIN-ANCHOR-color instead. Ye don’t need t' change anyth'n 'n yer custom color stylesheet as th' anchors now get their colors from --MAIN-LINK-color an' --MAIN-ANCHOR-HOVER-color respectively.

• New All shorrrtcodes now support named parameter. Th' positional parameter be still supported but will not be enhanced wit' new features, so ye don’t need t' change anyth'n 'n yer installat'n.

  This applies t' expand, include, notice an' siteparam.

• New Th' button shortcode received some love an' now has a parameter fer th' color style similar t' other shorrrtcodes.

• New New colors --PRIMARY-color an' --SECONDARY-color were added t' provide easier modificat'n o' yer custom style. Shorrrtcodes wit' a color style can now have primary or secondary as additional values.

  These two colors be th' default fer other, more specific color variables. Ye don’t need t' change anyth'n 'n yer exist'n custom color stylesheets as those variables get reason'ble default values.

• New Translat'n fer Polish. This language be not supported fer search.

• New Th' documentat'n fer all shorrrtcodes were revised.

3.4.0 (2022-04-03)

• Break'n If ye had previously overwritten th' custom-footer.html partial t' add visual elements below th' rrrambl'n o' yer plank, ye have t' move this rrrambl'n t' th' new partial content-footer.html. custom-footer.html was never meant t' contain HTML other than additional styles an' JavaScript.

• New If ye prefer expandable/collaps'ble menu items, ye can now set collapsibleMenu=true 'n yer config.toml. This will add arrows t' all menu items that contain sub menus. Th' menu will expand/collapse without navigat'n if ye click on an arrow.

• New Ye can activate print support 'n yer config.toml t' add th' capability t' print whole chapters or even th' complete ship.

• New Translat'n fer Traditional Chinese.

3.3.0 (2022-03-28)

• New Introduct'n o' new CSS variables t' set th' font. Th' theme distinguishes between --MAIN-font fer all rrrambl'n text an' --CODE-font fer inline or block code. There be additional overrides fer all head'ns. See th' theme variant generator o' th' exampleSite fer all avail'ble variables.

• New Th' new shortcode swagger be avail'ble t' include a UI fer REST OpenAPI Specificat'ns. See th' documentat'n fer avail'ble features. This feature will not work wit' Internet Explorer 11.

3.2.0 (2022-03-19)

• 0.93.0 This release requires a newer Cap'n Hugo version.

• Change In this release th' Merrrmaid JavaScript library will only be boarded on demand if th' plank contains a Merrrmaid shortcode or be us'n Merrrmaid codefences. This changes th' behavior o' disableMermaid config opt'n as follows: If a Merrrmaid shortcode or codefence be found, th' opt'n will be ignored an' Merrrmaid will be boarded regardlessly.

  Th' opt'n be still useful 'n case ye be us'n script'n t' set up yer graph. In this case no shortcode or codefence be involved an' th' library be not boarded by default. In this case ye can set disableMermaid=false 'n yer frontmatter t' force th' library t' be boarded. See th' theme variant generator o' th' exampleSite fer an example.

• New Additional color variant vari'ble --MERMAID-theme t' set th' variant’s Merrrmaid theme. This causes th' Merrrmaid theme t' switch wit' th' color variant if it defers from th' sett'n o' th' formerly selected color variant.

3.1.0 (2022-03-15)

• New attachment an' notice shorrrtcodes have a new parameter t' override th' default ay'con. Allowed values be all Font Awesome 5 Free ay'cons.

3.0.0 (2022-02-22)

• Break'n We made changes t' th' menu footer. If ye have yer menu-footer.html partial overridden, ye may have t' review th' styl'n (eg. margins/paddings) 'n yer partial. For a reference take a look into th' menu-footer.html partial that be com'n wit' th' exampleSite.

  This change was made t' allow yer own menu footer t' be placed right aft th' so called prefooter that comes wit' th' theme (contain'n th' language switch an' Clear history functionality).

• Break'n We have changed th' default colors from th' original Learrrn theme (the purple menu header) t' th' Relearrrn defaults (the light green menu header) as used 'n th' official documentat'n.

  This change will only affect yer installat'n if you’ve not set th' themeVariant parameter 'n yer config.toml. If ye still want t' use th' Learrrn color variant, ye have t' explicitly set themeVariant="learn" 'n yer config.toml.

  Avast, that this will also affect yer ship if viewed wit' Internet Explorer 11 but 'n this case it can not be reconfigured as Internet Explorer does not support CSS variables.

• Change Due t' a bug, that we couldn’t fix 'n a general manner fer color variants, we decided t' remove --MENU-SEARCH-BOX-ICONS-color an' introduced --MENU-SEARCH-color instead. Ye don’t need t' change anyth'n 'n yer custom color stylesheet as th' old name will be used as a fallback.

• Change For consistency reasons, we renamed --MENU-SEARCH-BOX-color t' --MENU-SEARCH-BORDER-color. Ye don’t need t' change anyth'n 'n yer custom color stylesheet as th' old name will be used as a fallback.

• New Wit' this release ye be now cap'ble t' define yer own dark mode variants.

  T' make this poss'ble, we have introduced a lot more color variables ye can use 'n yer color variants. Yer old variants will still work an' don’t need t' be changed as appropriate fallback values be used by th' theme. Nevertheless, th' new colors allow fer much more customizat'n.

  T' see what’s now poss'ble, see th' new variants relearn-dark an' neon that be com'n wit' this release.

• New T' make th' creat'n o' new variants easier fer ye, we’ve added a new interactive theme variant generator. This feature will not work wit' Internet Explorer 11.

• New Ye can now configure multiple color variants 'n yer config.toml. In this case, th' first variant be th' default chosen on first view an' a variant switch will be shown 'n th' menu footer. See th' documentat'n fer configurat'n.

  Avast, that th' new variant switch will not work wit' Internet Explorer 11 as it does not support CSS variables. Therefore, th' variant switcher will not be displayed wit' Internet Explorer 11.

2.9.0 (2021-11-19)

• Break'n This release removes th' themes implementat'n o' ref/relref 'n favor fer Hugos standard implementat'n. This be because o' inconsistencies wit' th' themes implementat'n. In advantage, yer project becomes standard compliant an' exchang'n this theme 'n yer project t' some other theme will be effortless.

  In a standard compliant form ye must not link t' th' *.md file but t' its logical name. You’ll see, referenc'n other planks becomes much easier. All three types result 'n th' same reference:

  Type	Non-Standard	Standard
  Branch bundle	basics/configuration/_index.md	basics/configurat'n
  Leaf bundle	basics/configuration/index.md	basics/configurat'n
  Plank	basics/configurat'n.md	basics/configurat'n

  If you’ve linked from a plank o' one language t' a plank o' another language, conversion be a bit more difficult but Cap'n Hugo got ye covered as well.

  Also, th' old themes implementat'n allowed refs t' non-exist'n rrrambl'n. This will cause Hugos implementat'n t' show th' error below an' abort th' generat'n. If yer project relies on this old behavior, ye can reconfigure th' error handl'n o' Hugos implementat'n.

  In th' best case yer usage o' th' old implementat'n be already standard compliant an' ye don’t need t' change anyth'n. You’ll notice this very easily once you’ve started hugo server aft an upgrade an' no errors be written t' th' console.

  Ye may see errors on th' console aft th' update 'n th' form:

  ERROR 2021/11/19 22:29:10 [en] REF_NOT_FOUND: Ref "basics/configuration/_index.md": "hugo-theme-relearn\exampleSite\content\_index.en.md:19:22": plank not found
  

  In this case, ye must apply one o' two opt'ns:

  1. Copy th' old implementat'n files theme/hugo-theme-relearn/layouts/shortcode/ref.html an' theme/hugo-theme-relearn/layouts/shortcode/relref.html t' yer own projects layouts/shortcode/ref.html an' layouts/shortcode/relref.html respectively. This be not recommended as yer project will still rely on non-standard behavior afterwards.

  2. Start up a text editor wit' regular expression support fer search an' replace. Apply th' follow'n conversions 'n th' given order on all *.md files. This be th' recommended choice.

  Type	Search	Replace by
  Branch bundle	(ref\s+"[^"]*)/_index\.md"	$1"
  Leaf bundle	(ref\s+"[^"]*)/index\.md"	$1"
  Plank	(ref\s+"[^"]*)\.md"	$1"

2.8.0 (2021-11-03)

• Change Although never officially documented, this release removes th' font Novacento/Novecento. If ye use it 'n an overwritten CSS please replace it wit' Work Sans. This change was necessary as Novacento did not provide all Latin special characters an' lead t' mixed styled character text eg. fer Czech.

• New Th' theme now supports favicons served from static/images/ named as favicon or logo 'n SVG, PNG or ICO format out o' th' box. An overridden partial layouts/partials/favicon.html may not be necessary anymore 'n most cases.

• New Ye can hide th' t'ble o' contents menu fer th' whole ship by sett'n th' disableToc opt'n 'n yer config.toml. For an example see th' example configurat'n.

2.7.0 (2021-10-24)

• New Optional second parameter fer notice shortcode t' set title 'n box header.

2.6.0 (2021-10-21)

• New Yer ship can now be served from a subfolder if ye set baseURL an' canonifyURLs=true 'n yer config.toml. See th' documentat'n fer a detailed example.

2.5.0 (2021-10-08)

• Change New colors --CODE-BLOCK-color an' --CODE-BLOCK-BG-color were added t' provide a fallback fer Hugos rules highlight'n 'n case guessSyntax=true be set. Ideally th' colors be set t' th' same values as th' ones from yer chosen chroma style.

2.4.0 (2021-10-07)

• Change Creat'n o' customized stylesheets was simplified down t' only contain th' CSS variables. Everyth'n else can an' should be deleted from yer custom stylesheet t' assure everyth'n works fine. For th' predefined stylesheet variants, this change be already included.

• New Hidden planks be displayed by default 'n their accord'n tags plank. Ye can now turn off this behavior by sett'n disableTagHiddenPages=true 'n yer config.toml.

• New Ye can define th' expansion state o' yer menus fer th' whole ship by sett'n th' alwaysopen opt'n 'n yer config.toml. Please see further documentat'n fer poss'ble values an' default behavior.

• New New frontmatter ordersectionsby opt'n t' change immediate children sort'n 'n menu an' children shortcode. Poss'ble values be title or weight.

• New Alternate rrrambl'n o' a plank be now advertised 'n th' HTML meta tags. See Cap'n Hugo documentat'n.

2.3.0 (2021-09-13)

• 0.81.0 This release requires a newer Cap'n Hugo version.

• New Showcase multilanguage features by provid'n a documentat'n translat'n “fer us pirrrates”. There will be no other translat'ns besides th' original English one an' th' Pirates one due t' maintenance constraints.

2.2.0 (2021-09-09)

• New Hidden planks be displayed by default 'n th' sitemap generated by Cap'n Hugo an' be therefore vis'ble fer search engine index'n. Ye can now turn off this behavior by sett'n disableSeoHiddenPages=true 'n yer config.toml.

2.1.0 (2021-09-07)

• 0.69.0 This release requires a newer Cap'n Hugo version.

• Change In case th' site’s structure contains additional *.md files not part o' th' ship (eg files that be meant t' be included by ship planks - see CHANGELOG.md 'n th' exampleSite), they will now be ignored by th' search.

• New Hidden planks be indexed fer th' ship search by default. Ye can now turn off this behavior by sett'n disableSearchHiddenPages=true 'n yer config.toml.

• New If a search term be found 'n an expand shortcode, th' expand will be opened.

• New Th' menu will scroll th' active item into view on board.

2.0.0 (2021-08-28)

• Change Rules highlight'n was switched t' th' built 'n Hugo mechanism. Ye may need t' configure a new stylesheet or decide t' roll ye own as described on 'n th' Cap'n Hugo documentat'n

• Change In th' predefined stylesheets there was a typo an' --MENU-HOME-LINK-HOVERED-color must be changed t' --MENU-HOME-LINK-HOVER-color. Ye don’t need t' change anyth'n 'n yer custom color stylesheet as th' old name will be used as a fallback.

• Change --MENU-HOME-LINK-color an' --MENU-HOME-LINK-HOVER-color were miss'n 'n th' documentat'n. Ye should add them t' yer custom stylesheets if ye want t' override th' defaults.

• Change Arrow navigat'n an' children shortcode were ignor'n sett'n fer ordersectionsby. This be now changed an' may result 'n different sort'n order o' yer sub planks.

• Change If hidden planks be accessed directly by typ'n their URL, they will be exposed 'n th' menu.

• Change A plank without a title will be treated as hidden=true.

• New Ye can define th' expansion state o' yer menus 'n th' frontmatter. Please see further documentat'n fer poss'ble values an' default behavior.

• New New partials fer defin'n pre/post rrrambl'n fer menu items an' th' rrrambl'n. See documentat'n fer further read'n.

Feel free t' edit those files by add'n some sample rrrambl'n an' replac'n th' title value 'n th' beginn'n o' th' files.

Launch'n th' website locally

Launch by us'n th' follow'n command:

hugo serve

Go t' http://localhost:1313

Ye should notice three th'ns:

1. Ye have a left-side Basics menu, contain'n two submenus wit' names equal t' th' title properties 'n th' previously created files.
2. Th' home plank explains how t' cust'mize it by follow'n th' instruct'ns.
3. When ye run hugo serve, when th' contents o' th' files change, th' plank automatically refreshes wit' th' changes. Neat!

Build th' website

When yer ship be ready t' deploy, run th' follow'n command:

hugo

A public folder will be generated, contain'n all static rrrambl'n an' assets fer yer website. It can now be deployed on any web server.

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.

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

Activate search

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.

[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 .

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.

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]
...
landingPageName = "<i class='fas fa-home'></i> Home"
...
[Languages.pir]
...
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:

Customizat'n

Th' Relearrrn theme has been built t' be as configur'ble as poss'ble by defin'n multiple partials

In themes/hugo-theme-relearn/layouts/partials/, ye will find all th' partials defined fer this theme. If ye need t' overwrite someth'n, don’t change th' code directly. Instead follow this plank. You’d create a new partial 'n th' layouts/partials folder o' yer local project. This partial will have th' priority.

This theme defines th' follow'n partials :

• header.html: th' header o' th' plank. See output-formats
• footer.html: th' footer o' th' plank. See output-formats
• body.html: th' body o' th' plank. Th' body may contain o' one or many articles. See output-formats
• article.html: th' output fer a single article, can contain elements around yer rrrambl'n. See output-formats
• menu.html: left menu. Not meant t' be overwritten
• search.html: search box. Not meant t' be overwritten
• custom-header.html: custom headers 'n plank. Meant t' be overwritten when add'n CSS imports. Don’t forget t' include style HTML tag directive 'n yer file.
• custom-footer.html: custom footer 'n plank. Meant t' be overwritten when add'n JavaScript. Don’t forget t' include javascript HTML tag directive 'n yer file.
• favicon.html: th' favicon
• heading-pre.html: side-wide configurat'n t' prepend t' planks title head'ns. If ye override this, it be yer responsibility t' take th' page’s headingPre sett'n into account.
• heading-post.html: side-wide configurat'n t' append t' planks title head'ns. If ye override this, it be yer responsibility t' take th' page’s headingPost sett'n into account.
• logo.html: th' logo, on top left hand corner
• meta.html: HTML meta tags, if ye want t' change default behavior
• menu-pre.html: side-wide configurat'n t' prepend t' menu items. If ye override this, it be yer responsibility t' take th' page’s menuPre sett'n into account.
• menu-post.html: side-wide configurat'n t' append t' menu items. If ye override this, it be yer responsibility t' take th' page’s menuPost sett'n into account.
• menu-footer.html: footer o' th' the left menu
• toc.html: t'ble o' contents
• rrrambl'n.html: th' rrrambl'n plank itself. This can be overridden if ye want t' display page’s meta data above or below th' rrrambl'n.
• content-footer: footer below th' rrrambl'n, has a default implementat'n but ye can overwrite it if ye don’t like it.

Change th' logo

Create a new file 'n layouts/partials/ named logo.html. Then write any HTML ye want. Ye could use an img HTML tag an' reference an image created under th' static folder, or ye could paste a SVG definit'n!

Change th' favicon

If yer favicon be a SVG, PNG or ICO, just drop off yer image 'n yer local static/images/ folder an' name it favicon.svg, favicon.png or favicon.ico respectively.

If no favicon file be found, th' theme will lookup th' alternative filename logo 'n th' same locat'n an' will repeat th' search fer th' list o' supported file types.

If ye need t' change this default behavior, create a new file 'n layouts/partials/ named favicon.html. Then write someth'n like this:

<link rel="icon" href="/images/favicon.bmp" type="image/bmp">

Change th' colors

Th' Relearrrn theme lets ye choose between some predefined color variants 'n light or dark mode, but feel free t' add one yourself!

Ye can preview th' shipped variants by chang'n them 'n th' variant selector at th' bottom o' th' menu.

Single variant

Set th' themeVariant value wit' th' name o' yer theme file. That’s it!

[params]
  themeVariant = "relearn-light"

In th' above example yer theme file has t' be named theme-relearn-light.css

Multiple variants

Ye can also set multiple variants. In this case, th' first variant be th' default chosen on first view an' a variant switch will be shown 'n th' menu footer.

[params]
  # Change default color scheme wit' a variant one.
  themeVariant = [ "relearn-light", "relearn-dark" ]

Roll yer own

If ye be not happy wit' th' shipped variants ye can either copy an' rename one o' th' shipped files from themes/hugo-theme-relearn/static/css t' static/css, edit them afterwards t' yer lik'n 'n a text editor an' configure th' themeVariant parameter 'n yer config.toml or just use th' interactive variant generator.

Output formats

Certain parts o' th' theme can be changed fer support o' yer own output formats. Eg. if ye define a new output format PLAINTEXT 'n yer config.toml, ye can add a file layouts/partials/header.plaintext.html t' change th' way, th' plank header should look like fer that output format.

Stylesheet generrrat'r

This interactive tool may help ye t' generate yer own color variant stylesheet.

T' get started, first select a color variant from th' variant switch that fits ye best as a start'n point.

Th' graph be interactive an' reflect th' current colors. Ye can click on any o' th' colored boxes t' adjust th' respective color. Th' graph an' th' plank will update accordingly.

Th' arrowed lines reflects how colors be inherited thru different parts o' th' theme if th' descendent isn’t overwritten. If ye want t' delete a color an' let it inherit from its parent, just delete th' value from th' input field.

T' better understand this select th' neon variant an' modify th' different head'n colors. There, colors fer th' head'n h2, h3 an' h4 be explicitly set. h5 be not set an' inherits its value from h4. h6 be also not set an' inherits its value from h5.

Once you’ve changed a color, th' variant switch will show a “My custom variant” entry an' yer changes be stored 'n th' browser. Ye can change planks an' even close th' browser without los'n yer changes.

Once ye be satisfied, ye can download th' new variants file an' copy it into yer site’s static/css directory. Afterwards ye have t' adjust th' themeVariant parameter 'n yer config.toml t' yer chosen file name.

Eg. if yer new variants file be named theme-my-custom-variant.css, ye have t' set themeVariant='my-custom-variant' t' use it.
