Here's an example:

:action: hello

[plantuml,subs=+attributes]
----
alice -> bob : {action}
----

In the above example, {action} should be replaced/substituted by hello.
You can use the following code to do that:

subs = attrs['subs']
content = parent.apply_subs(content, parent.resolve_subs(subs)) if subs

Let my old email domain expire without updating the rubygems.org account with my new email and now I cannot update the this gem.

This issue is to prove that I own and maintain this repo and the asciidoctor-plantuml gem in it.

Many security issues in Nokogiri need update.

Currently, the extension only works on listing blocks. Since Asciidoctor Diagram recognizes both literal and listing blocks I think it would be great to also enable this extension on literal blocks.
I also believe that a literal block is semantically more accurate than a listing block (but it might be subjective).

I think the main benefit would be that users won't have to update their document if they want to use Asciidoctor Diagram or this extension.

What do you think?

This Gem has a runtime dependency on Asciidoctor restricted to 1.5.x. In addition this Gem is used in GitLab and as a result it's not possible to upgrade to Asciidoctor 2.x.

Since Asciidoctor 2.x is mostly compatible with Asciidoctor 1.5.6+, we should loosen this restriction.

Hi!
I was wondering about a way of specifying a concrete plantuml.jar file for asciidoctor-pdf. The one coming with asciidoctor-pdf seems an older file than the version found in plantuml.com. Not being much of a ruby programmer I was looking through .rb for asciidoctor-pdf, and could not find any obvious parts...

Thanks!

Could you please create a new version tag including latest changes?

Project including your lib are still not up-to-date and won't have the updates until there is a new version

Thanks

I've to write diagram in chinese, therefore, I need to set font for the diagram.

Based on this comment #25 (comment) is important to assess the risk of this functionality.

Currently, it's not possible to use this extension when the output is not an HTML document. Using Block and Image object would allow to use this extension with Asciidoctor PDF and non-HTML converters (manpage, docbook...)

Could you please also add support for the block macro syntax?
See: https://github.com/asciidoctor/asciidoctor-diagram/#diagram-block-macro

I am often using plantuml::file.puml[] as it is shorter than the literal block version.

Thank you

The official plantuml.com server changed to URL format. Gitlab (and probably some other webapps) use asciidoctor-plantuml to create an image URL. Since the URL was changed, plantuml images are broken on Gitlab.

broken example from your testsuite

I copied the URL from your testsuite and changed the host

This works

Just by adding ~1 it's fixed
