Goldmark

Goldmark is from Hugo 0.60 the default library used for Markdown. It’s fast, it’s CommonMark compliant and it’s very flexible.

This is the default configuration:

config.

=== “yaml”

```yaml

      xhtml: false
```

=== “toml”

```toml
[markup]
  [markup.goldmark]
    [markup.goldmark.extensions]
      definitionList = true
      footnote = true
      linkify = true
      linkifyProtocol = 'https'

      wrapStandAloneImageWithinParagraph = true
      [markup.goldmark.parser.attribute]

        title = true
    [markup.goldmark.renderer]
      hardWraps = false
      unsafe = false
      xhtml = false
```

=== “json”

```json
{
   "markup": {
      "goldmark": {
         "extensions": {
            "definitionList": true,
            "footnote": true,
            "linkify": true,
            "linkifyProtocol": "https",
            "strikethrough": true,
            "table": true,
            "taskList": true,
            "typographer": true
         },
         "parser": {
            "attribute": {
               "block": false,
               "title": true
            },
            "autoHeadingID": true,
            "autoHeadingIDType": "github",
            "wrapStandAloneImageWithinParagraph": true
         },
         "renderer": {
            "hardWraps": false,
            "unsafe": false,
            "xhtml": false
         }
      }
   }
}
```

For details on the extensions, refer to this section of the Goldmark documentation

Some settings explained:

  • hardWraps

    By default, Goldmark ignores newlines within a paragraph. Set to true to render newlines as <br> elements.

  • unsafe

    By default, Goldmark does not render raw HTMLs and potentially dangerous links. If you have lots of inline HTML and/or JavaScript, you may need to turn this on.

  • typographer

    This extension substitutes punctuations with typographic entities like smartypants.

  • attribute

    Enable custom attribute support for titles and blocks by adding attribute lists inside single curly brackets ({.myclass class="class1 class2" }) and placing it after the Markdown element it decorates, on the same line for titles and on a new line directly below for blocks.

Hugo supports adding attributes (e.g. CSS classes) to Markdown blocks, e.g. tables, lists, paragraphs etc.

A blockquote with a CSS class:

1
2
3

> foo
> bar
{.myclass}

There are some current limitations: For tables you can currently only apply it to the full table, and for lists the ul/ol-nodes only, e.g.:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10

* Fruit
  * Apple
  * Orange
  * Banana
  {.fruits}
* Dairy
  * Milk
  * Cheese
  {.dairies}
{.list}

Note that attributes in code fences must come after the opening tag, with any other highlighting processing instruction, e.g.:

1
2
3

```go {.myclass linenos=table,hl_lines=[8,"15-17"],linenostart=199}
// ... code
```

  • autoHeadingIDType (“github”)

    The strategy used for creating auto IDs (anchor names). Available types are github, github-ascii and blackfriday. github produces GitHub-compatible IDs, github-ascii will drop any non-Ascii characters after accent normalization, and blackfriday will make the IDs compatible with Blackfriday, the default Markdown engine before Hugo 0.60. Note that if Goldmark is your default Markdown engine, this is also the strategy used in the anchorize template func.

Highlight

This is the default highlight configuration. Note that some of these settings can be set per code block, see Syntax Highlighting.

config.

=== “yaml”

```yaml
markup:
  highlight:
    anchorLineNos: false
    codeFences: true
    guessSyntax: false
    hl_Lines: ""
    hl_inline: false
    lineAnchors: ""
    lineNoStart: 1
    lineNos: false
    lineNumbersInTable: true
    noClasses: true
    noHl: false
    style: monokai
    tabWidth: 4
```

=== “toml”

```toml
[markup]
  [markup.highlight]
    anchorLineNos = false
    codeFences = true
    guessSyntax = false
    hl_Lines = ''
    hl_inline = false
    lineAnchors = ''
    lineNoStart = 1
    lineNos = false
    lineNumbersInTable = true
    noClasses = true
    noHl = false
    style = 'monokai'
    tabWidth = 4
```

=== “json”

```json
{
   "markup": {
      "highlight": {
         "anchorLineNos": false,
         "codeFences": true,
         "guessSyntax": false,
         "hl_Lines": "",
         "hl_inline": false,
         "lineAnchors": "",
         "lineNoStart": 1,
         "lineNos": false,
         "lineNumbersInTable": true,
         "noClasses": true,
         "noHl": false,
         "style": "monokai",
         "tabWidth": 4
      }
   }
}
```

For style, see these galleries:

For CSS, see Generate Syntax Highlighter CSS.

Table Of Contents

config.

=== “yaml”

```yaml
markup:
  tableOfContents:
    endLevel: 3
    ordered: false
    startLevel: 2
```

=== “toml”

```toml
[markup]
  [markup.tableOfContents]
    endLevel = 3
    ordered = false
    startLevel = 2
```

=== “json”

```json
{
   "markup": {
      "tableOfContents": {
         "endLevel": 3,
         "ordered": false,
         "startLevel": 2
      }
   }
}
```

These settings only works for the Goldmark renderer:

  • startLevel

    The heading level, values starting at 1 (h1), to start render the table of contents.

  • endLevel

    The heading level, inclusive, to stop render the table of contents.

  • ordered

    Whether or not to generate an ordered list instead of an unordered list.
