The variables in config file do not convert.

I want to use asciidoctor-diagram in the Hugo. I test the feature.

run hugo server, then throw an error:

$ hugo server

Failed to load AsciiDoc document - No such file or directory @ rb_sysopen - /diagrams/block.diag.

So, I want to set the project base dir as a asciidocotor variable which be used to find the /diagrams/block.diag.

I googled the document, and found the doucument: Configure Hugo | Hugo, there is some variables, such as project, contentDir and so on.

But when I used the variables as the document, the variables did not convert to the value:

INFO 2022/07/05 10:30:49 Rendering post/dive-into-encoding-and-character-set.adoc  using asciidoctor args [-r asciidoctor-comment-links -r asciidoctor-diagram -a include_dir2=:contentDir/static -a rouge-style=monokai -a source_attr=indent=0,subs="attributes,verbatim,quotes" -a include_dir=:project/static -a blockdiag-fontpath=/tmp/SourceHanSerifSC-Regular.otf -a icons=font -a source-highlighter=rouge -a image_attr=align=center,width=100% --no-header-footer -]

The param is -a include_dir=:project/static, not -a include_dir=/path/to/hugo/static.

And there is a problem: the diagram which is in the document, is not included was converted to the project base dir, not the build dir(public).

I found the solution:

1. add workingFolderCurrent = true to the config file:

# https://gohugo.io/content-management/formats/
[markup]
  [markup.asciidocExt]
    backend = 'html5'
    extensions = ["asciidoctor-comment-links", "asciidoctor-diagram"]
    safeMode = 'unsafe'
    sectionNumbers = false
    trace = false
    verbose = false
    workingFolderCurrent = true
    [markup.asciidocExt.attributes]
      icons = "font"
      source-highlighter = "rouge"
      rouge-style = "monokai"
      source_attr = "indent=0,subs=\"attributes,verbatim,quotes\""
      image_attr = "align=center,width=100%"
      blockdiag-fontpath = "/tmp/SourceHanSerifSC-Regular.otf"

2. add --destination=public/ to the hugo command.

$ hugo server --destination=public/ -v

This resolves the problem:
