Article #
Article
will embed a single article into a markdown file. The link
to the file should be the .RelPermalink
of the file to be embedded. Note that the shortcode will not display anything if it’s referencing it’s parent. Note: if you are running your website in a subfolder like Blowfish (i.e. /blowfish/) please include that path in the link.
Parameter | Description |
---|---|
link |
Required. the .RelPermalink to the target article. |
Example:
{{< article link="/docs/welcome/" >}}
Badge #
badge
outputs a styled badge component which is useful for displaying metadata.
Example:
{{< badge >}}
New article!
{{< /badge >}}
Button #
button
outputs a styled button component which can be used to highlight a primary action. It has two optional variables href
and target
which can be used to specify the URL and target of the link.
Example:
{{< button href="#button" target="_self" >}}
Call to action
{{< /button >}}
Carousel #
carousel
is used to showcase multiple images in an interactive and visually appealing way. This allows a user to slide through multiple images while only taking up the vertical space of a single one. All images are displayed using the full width of the parent component and using one of the predefined aspect ratios of 16:9
, 21:9
or 32:9
.
Parameter | Description |
---|---|
images |
Required. A regex string to match image names. |
aspectRatio |
Optional. The aspect ratio for the carousel. Either 16-9 , 21-9 or 32-9 . It is set to 16-9 by default. |
interval |
Optional. The interval for the auto-scrooling, specified in milliseconds. Defaults to 2000 (2s) |
Example 1: 16:9 aspect ratio and verbose list of images
{{< carousel images="{gallery/03.jpg, gallery/01.jpg, gallery/02.jpg, gallery/04.jpg}" >}}
Example 2: 21:9 aspect ratio and regex-ed list of images
{{< carousel images="gallery/*" aspectRatio="21-9" interval="2500" >}}
Chart #
chart
uses the Chart.js library to embed charts into articles using simple structured data. It supports a number of
different chart styles and everything can be configured from within the shortcode. Simply provide the chart parameters between the shortcode tags and Chart.js will do the rest.
Refer to the official Chart.js docs for details on syntax and supported chart types.
Example:
{{< chart >}}
type: 'bar',
data: {
labels: ['Tomato', 'Blueberry', 'Banana', 'Lime', 'Orange'],
datasets: [{
label: '# of votes',
data: [12, 19, 3, 5, 3],
}]
}
{{< /chart >}}
You can see some additional Chart.js examples on the charts samples page.
Figure #
Blowfish includes a figure
shortcode for adding images to content. The shortcode replaces the base Hugo functionality in order to provide additional performance benefits.
When a provided image is a page resource, it will be optimised using Hugo Pipes and scaled in order to provide images appropriate to different device resolutions. If a static asset or URL to an external image is provided, it will be included as-is without any image processing by Hugo.
The figure
shortcode accepts six parameters:
Parameter | Description |
---|---|
src |
Required. The local path/filename or URL of the image. When providing a path and filename, the theme will attempt to locate the image using the following lookup order: Firstly, as a
page resource bundled with the page; then an asset in the assets/ directory; then finally, a static image in the static/ directory. |
alt |
Alternative text description for the image. |
caption |
Markdown for the image caption, which will be displayed below the image. |
class |
Additional CSS classes to apply to the image. |
href |
URL that the image should be linked to. |
default |
Special parameter to revert to default Hugo figure behaviour. Simply provide default=true and then use normal
Hugo shortcode syntax. |
Blowfish also supports automatic conversion of images included using standard Markdown syntax. Simply use the following format and the theme will handle the rest:
![Alt text](image.jpg "Image caption")
Example:
{{< figure
src="abstract.jpg"
alt="Abstract purple artwork"
caption="Photo by [Jr Korpa](https://unsplash.com/@jrkorpa) on [Unsplash](https://unsplash.com/)"
>}}
<!-- OR -->
![Abstract purple artwork](abstract.jpg "Photo by [Jr Korpa](https://unsplash.com/@jrkorpa) on [Unsplash](https://unsplash.com/)")
Gallery #
gallery
allows you to showcase multiple images at once, in a responsive manner with more varied and interesting layouts.
In order to add images to the gallery, use img
tags for each image and add class="grid-wXX"
in order for the gallery to be able to identify the column width for each image. The widths available by default start at 10% and go all the way to 100% in 5% increments. For example, to set the width to 65%, set the class to grid-w65
. Additionally, widths for 33% and 66% are also available in order to build galleries with 3 cols. You can also leverage tailwind’s responsive indicators to have a reponsive grid.
Example 1: normal gallery
{{< gallery >}}
<img src="gallery/01.jpg" class="grid-w33" />
<img src="gallery/02.jpg" class="grid-w33" />
<img src="gallery/03.jpg" class="grid-w33" />
<img src="gallery/04.jpg" class="grid-w33" />
<img src="gallery/05.jpg" class="grid-w33" />
<img src="gallery/06.jpg" class="grid-w33" />
<img src="gallery/07.jpg" class="grid-w33" />
{{< /gallery >}}
Example 2: responsive gallery
{{< gallery >}}
<img src="gallery/01.jpg" class="grid-w50 md:grid-w33 xl:grid-w25" />
<img src="gallery/02.jpg" class="grid-w50 md:grid-w33 xl:grid-w25" />
<img src="gallery/03.jpg" class="grid-w50 md:grid-w33 xl:grid-w25" />
<img src="gallery/04.jpg" class="grid-w50 md:grid-w33 xl:grid-w25" />
<img src="gallery/05.jpg" class="grid-w50 md:grid-w33 xl:grid-w25" />
<img src="gallery/06.jpg" class="grid-w50 md:grid-w33 xl:grid-w25" />
<img src="gallery/07.jpg" class="grid-w50 md:grid-w33 xl:grid-w25" />
{{< /gallery >}}
GitHub Card #
github
allows you to quickly link a github repository, all while showing and updating in realtime stats about it, such as the number of stars and forks it has.
Parameter | Description |
---|---|
repo |
[String] github repo in the format of username/repo |
Example 1:
{{< github repo="nunocoracao/blowfish" >}}
Personal Website & Blog Theme for Hugo
GitLab Card #
gitlab
allows you to quickly link a GitLab Project (GitLab’s jargon for repo).
It displays realtime stats about it, such as the number of stars and forks it has.
Unlike github
it can’t display the main programming language of a project.
Finaly custom GitLab instace URL can be provided, as long as the api/v4/projects/
endpoint is available, making this shortcode compatible with most self-hosted / entreprise deployments.
Parameter | Description |
---|---|
projectID |
[String] gitlab numeric ProjectID |
baseURL |
[String] optional gitlab instace URL, default is https://gitlab.com/ |
Example 1:
{{< gitlab projectID="278964" >}}
GitLab is an open source end-to-end software development platform with built-in version control, issue tracking, code review, CI/CD, and more. Self-host GitLab on your own servers, in a container, or on a cloud provider.
Icon #
icon
outputs an SVG icon and takes the icon name as its only parameter. The icon is scaled to match the current text size.
Example:
{{< icon "github" >}}
Output:
Icons are populated using Hugo pipelines which makes them very flexible. Blowfish includes a number of built-in icons for social, links and other purposes. Check the icon samples page for a full list of supported icons.
Custom icons can be added by providing your own icon assets in the assets/icons/
directory of your project. The icon can then be referenced in the shortcode by using the SVG filename without the .svg
extension.
Icons can also be used in partials by calling the icon partial.
Katex #
The katex
shortcode can be used to add mathematical expressions to article content using the KaTeX package. Refer to the online reference of
supported TeX functions for the available syntax.
To include mathematical expressions in an article, simply place the shortcode anywhere with the content. It only needs to be included once per article and KaTeX will automatically render any markup on that page. Both inline and block notation are supported.
Inline notation can be generated by wrapping the expression in \\(
and \\)
delimiters. Alternatively, block notation can be generated using $$
delimiters.
Example:
{{< katex >}}
\\(f(a,b,c) = (a^2+b^2+c^2)^3\\)
\(f(a,b,c) = (a^2+b^2+c^2)^3\)
Check out the mathematical notation samples page for more examples.
Lead #
lead
is used to bring emphasis to the start of an article. It can be used to style an introduction, or to call out an important piece of information. Simply wrap any Markdown content in the lead
shortcode.
Example:
{{< lead >}}
When life gives you lemons, make lemonade.
{{< /lead >}}
List #
List
will display a list of recent articles. This shortcode requires a limit value to constraint the list. Additionally, it supports a where
and a value
in order to filter articles by their parameters. Note that this shortcode will not display its parent page but it will count for the limit value.
Parameter | Description |
---|---|
limit |
Required. the number of recent articles to display. |
title |
Optional title for the list, default is Recent |
where |
The variable to be used for the query of articles e.g. Type |
value |
The value that will need to match the parameter defined in where for the query of articles e.g. for where == Type a valid value could be sample |
where
and value
values are used in the following query where .Site.RegularPages $where $value
in the code of the shortcode. Check
Hugo docs to learn more about which parameters are available to use.
Example #1:
{{< list limit=2 >}}
Recent
Create an article card
Example #2:
{{< list title="Samples" limit=5 where="Type" value="sample" >}}
Samples
Mermaid #
mermaid
allows you to draw detailed diagrams and visualisations using text. It uses Mermaid under the hood and supports a wide variety of diagrams, charts and other output formats.
Simply write your Mermaid syntax within the mermaid
shortcode and let the plugin do the rest.
Refer to the official Mermaid docs for details on syntax and supported diagram types.
Example:
{{< mermaid >}}
graph LR;
A[Lemons]-->B[Lemonade];
B-->C[Profit]
{{< /mermaid >}}
You can see some additional Mermaid examples on the diagrams and flowcharts samples page.
Swatches #
swatches
outputs a set of up to three different colors to showcase color elements like a color palette. This shortcode takes the HEX
codes of each color and creates the visual elements for each.
Example
{{< swatches "#64748b" "#3b82f6" "#06b6d4" >}}
Output
Timeline #
The timeline
creates a visual timeline that can be used in different use-cases, e.g. professional experience, a project’s achievements, etc. The timeline
shortcode relies on the timelineItem
sub-shortcode to define each item within the main timeline. Each item can have the following properties.
Parameter | Description |
---|---|
icon |
the icon to be used in the timeline visuals. |
header |
header for each entry |
badge |
text to place within the top righ badge |
