Custom ruby extension for PDF generation

[kneisslm]

I try to add a custom ruby extension to process a document in order to modify the title page of a PDF document.

I have added

  rubyExtensions = ['asciidoctor-pdf-extensions.rb']

in docToolchainConfig.groovy .

With docToolchain-3.0.2 I get

FAILURE: Build failed with an exception.

* Where:
Script '/Users/kneissl/.sdkman/candidates/doctoolchain/3.0.2/scripts/AsciiDocBasics.gradle' line: 246

* What went wrong:
A problem occurred evaluating script.
> Cannot set the value of read-only property 'requires' for task ':asciidoctor' of type org.asciidoctor.gradle.jvm.AsciidoctorTask.

This is very close to the issue posted by @davidschottel in #1239 (comment)_

I am really new to docToolchain so I am not yet able to apply his solution to my problem.

I have the same issue (requires[] cannot be updated).
By the way, how to use an extension directly from ruby repository instead of copying it locally ?

dependencies {
  asciidoctorGems 'rubygems:asciidoctor-lists:1.0.9'
  asciidoctorGems 'rubygems:asciidoctor-bibliography:0.11.0'
}
...
asciidoctorj {
 ...
  requires 'asciidoctor-lists'
  requires 'asciidoctor-bibliography'
}

Hi, any new for remote access to ruby repository?

Thanks for bringing this up, remote access will be targeted as extra feature, for now the functionality is limited to local custom extensions only. However, i do see value in this feature, but need to prioritize :)
