Plantuml diagrams stopped working in pdf

[LukeCz]

Observed vs. expected behavior

Embedded diagrams rendered with Kroki (default public server) are displayed fine in preview but fail to rendered in pdf - replaced by broken links. The issue is that the embedded link in pdf is broken into multiple lines. In the example provided in the attachment the link is

[Diagram] |
https://kroki.io/plantuml/svg/eNpzKC5JLCopzc3hKs7OzCtILErMVQjJLMlJdcvPKwkuqcxJVcjLL8pNzOE
qAYkqqJalFhVn5udpaHI5pOalADUCAEw8GJc=

while it should be a single line. I.e. if you manually concatenate the 2 lines it is a valid URL but when opening in pdf viewer only the first line is clickable as a link.

Steps to reproduce

example.zip Just a simplest adoc file, does not matter if part of Antora structure or not. Kroki server enabled in settings with default (empty) URL.

Thanks for reporting this. I had a look and found that this generated a warning in my IDE's notifications:

WARN uri:classloader:/gems/asciidoctor-pdf-2.3.4/lib/asciidoctor/pdf/converter.rb:resolve_image_path: cannot embed remote image: https://kroki.io/plantuml/svg/eNpzKC5JLCopzc3hKs7OzCtILErMVQjJLMlJdcvPKwkuqcxJVcjLL8pNzOEqAYkqqJalFhVn5udpaHI5pOalADUCAEw8GJc= (allow-uri-read attribute not enabled)

When setting the allow-uri-read attribute in the plugin's settings, this will work as expected:

I'll update the next version of the plugin that when Kroki is enabled, the allow-uri-read is set automatically for both PDF and HTML.

I prepared the change and it will be part of the next release. I also update the docs. I'll comment here once a pre-release is available.

This is part of pre-release 0.38.13. Please let me know if you still experience issues.

The pre-release of the plugin is available from GitHub releases and the IntelliJ AsciiDoc EAP repository.
