Chromium dependency in asciidoctorj CLI

I usually am building documentation via gradle but today I installed the asciidoctorj CLI for converting one-off documents quickly. However, I'm having trouble rendering a mermaid diagram. I'm getting this:

PS C:\> asciidoctorj.bat -r asciidoctor-diagram .\mag-workitem.adoc

I do have a version of chromium installed, though apparently it's not at the requested version:

PS C:\> npm list chromium
C:\Users\MyPowerShell
`-- chromium@3.0.2

Any suggestions on either getting this CLI to work or another CLI option with which I can process mermaid diagrams?

Andy,

The dependency on Chrome is coming indirectly from Asciidoctor Diagram (not the AsciidoctorJ CLI directly). Asciidoctor Diagram allows you to pass a config file to puppeteer using the `puppeteer-config` attribute. See https://docs.asciidoctor.org/diagram-extension/latest/#mermaid From there, you can tell puppeteer which binary to use. See https://github.com/puppeteer/puppeteer/blob/v8.0.0/docs/api.md#puppeteerlaunchoptions

Puppeteer does claim to use a bundled distribution of Chromium by default, so I'm not sure why it has to be specified. But perhaps you can figure it out ;)

Best Regards,

-Dan

Re: Chromium dependency in asciidoctorj CLI

OOPs, I missed that extra documentation!

I tried a few things with the environment variables (setting PUPPETEER_CHROMIUM_REVISION, then trying to switch to firefox with PUPPETEER_PRODUCT). Turns out that chromium was not installed, after I went into the module and ran npm install then it installed the version of chromium that it wanted.

Thanks for the pointer, Dan!
