Extract variable (document attribute)

[ggrossetie]

Feature request

It would be nice to be able to use the extract variable feature when editing an AsciiDoc document.

Here's an example:

= Document

The IntelliJ AsciiDoc Plugin provides support for the AsciiDoc markup language. 
You can install the IntelliJ AsciiDoc Plugin from the plugins section inside your JetBrains IDE or download it from the JetBrains Plugin Repository.

Here the product name ("IntelliJ AsciiDoc Plugin") is duplicated. What I want to do is select the text "IntelliJ AsciiDoc Plugin", then type Ctrl+Alt+v:

The "Variable declaration" block could ask if the variable should be extract as a document attribute (ie. in the document header) or as an "inline" attribute in the paragraph/section.

Ideally we should also ask the user to replace all the occurrences:

Let's say I want to extract the variable as a document attribute and that I want to replace all occurrences, here's the result:

= Document
:product-name: IntelliJ AsciiDoc Plugin

The {product-name} provides support for the AsciiDoc markup language. 
You can install the {product-name} from the plugins section inside your JetBrains IDE or download it from the JetBrains Plugin Repository.

Here's another example:

= Document
:gh-repo-browser-ext: https://github.com/asciidoctor/asciidoctor-browser-extension
:gh-repo-intellij-plugin: https://github.com/asciidoctor/asciidoctor-intellij-plugin

= Document
:gh-org: https://github.com/asciidoctor
:gh-repo-browser-ext: {gh-org}/asciidoctor-browser-extension
:gh-repo-intellij-plugin: {gh-org}/asciidoctor-intellij-plugin
