Lua filter utils

[jmbuhr]

this PR exports quarto.base64 together with the already exported quarto.utils and quarto.json for use in lua filters. This is helpful for writing filters that can create self-contained htmls.

@cscheid I'm assuming that the addition to .gitignore is fine here?

@dragonstyle Are we okay with adding the quarto.base64 module or should we consider re-organizing to e.g. quarto.encoding.json, quarto.encoding.base64. I'm personally fine with quarto.base64 but just wanted to double-check with you.

I think this makes sense at the root level too, vs trying to next everything in namespaces. I'm good with quarto.base64

[cscheid]

@jjallaire yeah, that looks safe. I was under the impression that we only keep those now when the vendoring process fails and we can't roll it back for whatever reason.

@jmbuhr Are you having issues with those files hanging onto your filesystem? Maybe we should open a separate gh issue to track.

[jmbuhr]

@cscheid Yes. So I assume these where supposed to be deleted during the cleanup steps.
These are the files that stick around:

$ ls src/vendor-2022-08-15 
cdn.skypack.dev  deno.land  import_map.json

[cscheid]

@jmbuhr It seems that we're rolling back on failure but not throwing away the old version on success. Thanks for catching that! I'll fix right away.

[cscheid]

I just pushed a change to main that cleans those up. We can keep the .gitignore addition, but it should no longer be necessary.
