Asciidoctor parameters can be customized in Hugo:
{{% note %}}
External `asciidoctor` command requires Hugo rendering to _disk_ to a specific destination directory. It is required to run Hugo with the command option `--destination`.
{{% /note %}}
Parameter | Default | Comment
--- | --- | ---
backend | `html5` | Don't change this unless you know what you are doing.
doctype | `article` | Currently supported Document type is `article`.
extensions | | Possible extensions are `asciidoctor-html5s`, `asciidoctor-bibtex`, `asciidoctor-diagram`, `asciidoctor-interdoc-reftext`, `asciidoctor-katex`, `asciidoctor-latex`, `asciidoctor-mathematical`, `asciidoctor-question`, `asciidoctor-rouge`.
attributes | | Variables to be referenced in your `adoc` file. This is a list of variable name/value maps. See [Asciidoctor#attributes](https://asciidoctor.org/docs/asciidoc-syntax-quick-reference/#attributes-and-substitutions).
noheaderorfooter | true | Output an embeddable document, which excludes the header, the footer, and everything outside the body of the document. Don't change this unless you know what you are doing.
safemode | `unsafe` | Safe mode level `unsafe`, `safe`, `server` or `secure`. Don't change this unless you know what you are doing.
sectionnumbers | `false` | Auto-number section titles.
verbose | `false` | Verbosely print processing information and configuration file checks to stderr.
trace | `false` | Include backtrace information on errors.
failurelevel | `fatal` | The minimum logging level that triggers a non-zero exit code (failure).
workingfoldercurrent | `false` | Set the working folder to the rendered `adoc` file, so [include](https://asciidoctor.org/docs/asciidoc-syntax-quick-reference/#include-files) will work with relative paths. This setting uses the `asciidoctor` cli parameter `--base-dir` and attribute `outdir=`. For rendering [asciidoctor-diagram](https://asciidoctor.org/docs/asciidoctor-diagram/) `workingfoldercurrent` must be set to `true`.
Some [Asciidoctor](https://asciidoctor.org/man/asciidoctor/) parameters can be customized in Hugo:
Parameter | Comment
--- | ---
backend | Don't change this unless you know what you are doing.
doctype | Currently, the only document type supported in Hugo is `article`.
extensions | Possible extensions are `asciidoctor-html5s`, `asciidoctor-bibtex`, `asciidoctor-diagram`, `asciidoctor-interdoc-reftext`, `asciidoctor-katex`, `asciidoctor-latex`, `asciidoctor-mathematical`, `asciidoctor-question`, `asciidoctor-rouge`.
attributes | Variables to be referenced in your AsciiDoc file. This is a list of variable name/value maps. See [Asciidoctor's attributes](https://asciidoctor.org/docs/asciidoc-syntax-quick-reference/#attributes-and-substitutions).
noHeaderOrFooter | Output an embeddable document, which excludes the header, the footer, and everything outside the body of the document. Don't change this unless you know what you are doing.
safeMode | Safe mode level `unsafe`, `safe`, `server` or `secure`. Don't change this unless you know what you are doing.
sectionNumbers | Auto-number section titles.
verbose | Verbosely print processing information and configuration file checks to stderr.
trace | Include backtrace information on errors.
failureLevel | The minimum logging level that triggers a non-zero exit code (failure).
Hugo provides additional settings that don't map directly to Asciidoctor's CLI options:
workingFolderCurrent
: Sets the working directory to be the same as that of the AsciiDoc file being processed, so that [include](https://asciidoctor.org/docs/asciidoc-syntax-quick-reference/#include-files) will work with relative paths. This setting uses the `asciidoctor` cli parameter `--base-dir` and attribute `outdir=`. For rendering diagrams with [asciidoctor-diagram](https://asciidoctor.org/docs/asciidoctor-diagram/), `workingFolderCurrent` must be set to `true`.
preserveTOC
: By default, Hugo removes the table of contents generated by Asciidoctor and provides it through the built-in variable [`.TableOfContents`](/content-management/toc/) to enable further customization and better integration with the various Hugo themes. This option can be set to `true` to preserve Asciidoctor's TOC in the generated page.
Below are all the AsciiDoc related settings in Hugo with their default values:
{{< code-toggle config="markup.asciidocExt" />}}
Example of how to set extensions and attributes:
```
[markup.asciidocext]
[markup.asciidocExt]
extensions = ["asciidoctor-html5s", "asciidoctor-diagram"]
workingFolderCurrent = true
[markup.asciidocext.attributes]
[markup.asciidocExt.attributes]
my-base-url = "https://example.com/"
my-attribute-name = "my value"
```
Important: External `asciidoctor` requires Hugo rendering to _disk_ to a specific destination folder. It is required to run Hugo with the command option `--destination`!
In a complex Asciidoctor environment it is sometimes helpful to debug the exact call to your external helper with all
parameters. Run Hugo with `-v`. You will get an output like
