# AsciiDoc

Learn how Vale handles AsciiDoc content.

AsciiDoc is supported through the external program [Asciidoctor](https://asciidoctor.org/). See their [installation](https://docs.asciidoctor.org/asciidoctor/latest/install) instructions to get started. You’ll need to ensure that the `asciidoctor` executable is available in your `$PATH`.

The supported extensions are `.adoc`, `.asciidoc`, and `.asc`.

By default, Vale ignores:

* [Literals and source code](https://docs.asciidoctor.org/asciidoc/latest/syntax-quick-reference/#literals-and-source-code).
* URLs: See [URL handling](https://github.com/errata-ai/vale/issues/320) for more information.

## [Attributes](#attributes)

You can customize how `asciidoctor` is called by passing [document attributes](https://docs.asciidoctor.org/asciidoc/latest/attributes/document-attributes-ref/):

```ini
StylesPath = styles

[asciidoctor]
# attribute = value
#
# where 'YES' enables and 'NO' disables.

# enable
experimental = YES

# assign a specific value
attribute-missing = drop

[*.adoc]
BasedOnStyles = Vale
```

## [Comments](#comments)

Heads up!

Make sure the surround the inline passthrough statements with newlines, as shown below.

Vale supports comment-based configuration in AsciiDoc files:

* Turn Vale off entirely:

```adoc
pass:[<!-- vale off -->]

This text will be ignored.

pass:[<!-- vale on -->]
```

* Turn off a specific rule:

```adoc
pass:[<!-- vale Style.Redundancy = NO -->]

This is some text ACT test

pass:[<!-- vale Style.Redundancy = YES -->]
```

* Turn off specific match(es) within a rule:

```adoc
pass:[<!-- vale Style.Redundancy["ACT test","OTHER"] = NO -->]

This is some text ACT test

pass:[<!-- vale Style.Redundancy["ACT test","OTHER"] = YES -->]
```

* Turn on or off specific styles:

```adoc
pass:[<!-- vale StyleName1 = YES -->]
pass:[<!-- vale StyleName2 = NO -->]
```

* Set styles (enabling them and switching off any other styles):

```adoc
pass:[<!-- vale style = StyleName1 -->]
pass:[<!-- vale styles = StyleName1, StyleName2 -->]
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vale.sh/formats/asciidoc.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
