The mermaid shortcode supports diagrams in Hugo with Mermaid library.

Mermaid is a library helping you to generate diagram and flowcharts from text, in a similar manner as Markdown.

Just insert your mermaid code in the mermaid shortcode and that’s it.

1 Flowchart

Example flowchart mermaid input:

{{</* mermaid */>}}
graph LR;
    A[Hard edge] -->|Link text| B(Round edge)
    B --> C{Decision}
    C -->|One| D[Result one]
    C -->|Two| E[Result two]
{{</* /mermaid */>}}

The rendered output looks like this:

{{< mermaid >}} graph LR; A[Hard edge] -->|Link text| B(Round edge) B --> C{Decision} C -->|One| D[Result one] C -->|Two| E[Result two] {{< /mermaid >}}

2 Sequence Diagram

Example sequence diagram mermaid input:

{{</* mermaid */>}}
sequenceDiagram
    participant Alice
    participant Bob
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->John: Fight against hypochondria
    end
    Note right of John: Rational thoughts <br/>prevail...
    John-->Alice: Great!
    John->Bob: How about you?
    Bob-->John: Jolly good!
{{</* /mermaid */>}}

The rendered output looks like this:

{{< mermaid >}} sequenceDiagram participant Alice participant Bob Alice->>John: Hello John, how are you? loop Healthcheck John->John: Fight against hypochondria end Note right of John: Rational thoughts
prevail... John-->Alice: Great! John->Bob: How about you? Bob-->John: Jolly good! {{< /mermaid >}}

3 GANTT

Example GANTT mermaid input:

{{</* mermaid */>}}
gantt
    dateFormat  YYYY-MM-DD
    title Adding GANTT diagram functionality to mermaid
    section A section
    Completed task            :done,    des1, 2014-01-06,2014-01-08
    Active task               :active,  des2, 2014-01-09, 3d
    Future task               :         des3, after des2, 5d
    Future task2               :         des4, after des3, 5d
    section Critical tasks
    Completed task in the critical line :crit, done, 2014-01-06,24h
    Implement parser and jison          :crit, done, after des1, 2d
    Create tests for parser             :crit, active, 3d
    Future task in critical line        :crit, 5d
    Create tests for renderer           :2d
    Add to mermaid                      :1d
{{</* /mermaid */>}}

The rendered output looks like this:

{{< mermaid >}} gantt dateFormat YYYY-MM-DD title Adding GANTT diagram functionality to mermaid section A section Completed task :done, des1, 2014-01-06,2014-01-08 Active task :active, des2, 2014-01-09, 3d Future task : des3, after des2, 5d Future task2 : des4, after des3, 5d section Critical tasks Completed task in the critical line :crit, done, 2014-01-06,24h Implement parser and jison :crit, done, after des1, 2d Create tests for parser :crit, active, 3d Future task in critical line :crit, 5d Create tests for renderer :2d Add to mermaid :1d {{< /mermaid >}}

4 Class Diagram

Example class diagram mermaid input:

{{</* mermaid */>}}
classDiagram
    Class01 <|-- AveryLongClass : Cool
    Class03 *-- Class04
    Class05 o-- Class06
    Class07 .. Class08
    Class09 --> C2 : Where am i?
    Class09 --* C3
    Class09 --|> Class07
    Class07 : equals()
    Class07 : Object[] elementData
    Class01 : size()
    Class01 : int chimp
    Class01 : int gorilla
    Class08 <--> C2: Cool label
{{</* /mermaid */>}}

The rendered output looks like this:

{{< mermaid >}} classDiagram Class01 <|-- AveryLongClass : Cool Class03 -- Class04 Class05 o-- Class06 Class07 .. Class08 Class09 --> C2 : Where am i? Class09 -- C3 Class09 --|> Class07 Class07 : equals() Class07 : Object[] elementData Class01 : size() Class01 : int chimp Class01 : int gorilla Class08 <--> C2: Cool label {{< /mermaid >}}

{{</* mermaid */>}}
stateDiagram
    [*] --> Still
    Still --> [*]
    Still --> Moving
    Moving --> Still
    Moving --> Crash
    Crash --> [*]
{{</* /mermaid */>}}

The rendered output looks like this:

{{< mermaid >}} stateDiagram [] --> Still Still --> [] Still --> Moving Moving --> Still Moving --> Crash Crash --> [*] {{< /mermaid >}}

6 Git Graph
