Error creating html for file with definition list #62

Closed habamax closed 5 years ago

habamax commented 5 years ago

With the following test.adoc:

= Test doc

== Test

DefList:: 
    * List item

and the command asciidoctor -r asciidoctor-bibtex test.adoc I get following record:

asciidoctor: FAILED: C:/Users/maksim.kim/docs/test.adoc: Failed to load AsciiDoc document - undefined method `empty?' for nil:NilClass
  Use --trace for backtrace

The same error is with asciidoctor-pdf.

PS

with --trace I get:

There is no error if I add text to DefList line:

= Test doc

== Test

DefList:: hello
    * List item

Looks like block.instance_variable_get(:@text) is nil for a deflist without immediate text on the same line: https://github.com/asciidoctor/asciidoctor-bibtex/blob/1d1f66740bc059c22ade965cb6ec5a70ffea7519/lib/asciidoctor-bibtex/extensions.rb#L114-L115

and it is duplicate #58

I had the same issue and solved it by updating asciidoctor-bibtex through the following:

gem install asciidoctor-bibtex

I am running Asciidoctor 2.0.12 on macOS Catalina.
