fix asciidoc preview when antora.yml does not specify version

[alaindresse]

Resolves #882

Currently, if our antora.yml does not specify a version (required to add a fallback for the version in the antora playbook), it is impossible to preview an asciidoc file.

This pull request extends the approach from @leonardopavanrocha in #871, namely setting the version to an empty string when it is not specified in antora.yml.

Note:: I also had to bumb the vscode engine number to test this.

Changed my code to set version to a short hash of the path of the antora.yml. I was getting issues with duplicate versions for components for which the source was distributed across several folders in the repo.

Use case for the duplication: monorepo with documentation of individual components that I want to consolidate into a single component with appropriate navigation.

According to the documentation the version is "mandatory" unless inherited from the content source in the playbook. Is that your case?

@ggrossetie thanks for taking the time to look into this despite your busy schedule!

Yes, that is exactly the case:

• If I add the version in the playbook, then it is no longer mandatory in the antora.yml, and should actually be absent for the version in the playbook to work.
• If I accordingly remove the version from the antora.yml, before my changes, I have to preview in vscode, even though the antora generation works nicely with no errors or warnings.

@alaindresse Left a few comments otherwise 👍🏻

One test is failing because we assert that the version is null but the value is now a random value:

I don't think we should generate a random value when the version is explicitly null with the ~ symbol.

The ~ values defines a component version as unversioned

@ggrossetie thanks for your comments. I believe they are now addressed.

I ran the tests, using npm run test and saw a message saying that all tests passed, but I also saw:

Failed to load message bundle for file /Users/alaindresse/code/asciidoctor-vscode/dist/src/features/antora/antoraSupport
Failed to load message bundle for file /Users/alaindresse/code/asciidoctor-vscode/dist/src/asciidoctorWebViewConverter

And did not see any report on the antoraSupport tests.

What is the proper way to run the tests ?

[ggrossetie]

@alaindresse Thanks, could you please run npm i locally and commit the package-lock.json. Apart from that 👍🏻

I ran the tests, using npm run test and saw a message saying that all tests passed, but I also saw:

Message bundle does not properly load during tests (or at least I don't know how to make them work in tests) but it does not prevent tests from running. So this messages can be safely ignored 😅

All good 🎉 Thanks!
