Configure directory in Assets emitter

[franco-ruggeri]

Is your feature request related to a problem? Please describe.

Consider the Assets emitter. It is not possible to emit non-markdown files only from a specific subfolder (e.g., _assets). To the best of my knowledge, using ignorePatterns, there is no way to:

• Include non-markdown files in a specific subfolder (e.g., _assets).
• Exclude non-markdown files elsewhere.

Even if there is a particular ignorePatterns to achieve that, globby will still have to scan the whole folder. With a huge content folder containing a lot of non-markdown files that don't need to be included, it is really slow.

I have this problem in my setup:

• I mount the content folder from the cloud. So, it contains a lot of non-markdown files.
• The assets linked in markdown documents are in a specific subfolder: _assets. All the other assets are unrelated to Markdown documents and not needed in the generated static site. So, my final static site only needs to include _assets + markdown files.

Describe the solution you'd like

Add a configuration for the Assets emitter to only scan a subfolder. Specifically, we'd need to make the first parameter to glob here configurable in quartz.config.ts.

Additional context

[franco-ruggeri]

I managed to find an ignore pattern that actually works: it ignores non-markdown files outside _assets. And the Assets emitter is not slow even with a large content folder. It scanned 1 TB in probably less than a minute, so it's ok.

The pattern is:

'!(_assets)/**/*.!(md)'

It could be good to add it to the documentation for others. I was struggling with it for some time.

Closing the issue.

Re-opening this issue, as the ignore pattern '!(_assets)/**/*.!(md)' conflicts with chokidar. Specifically, if I add '!(_assets)/**/*.!(md)' to ignorePatterns, quartz with the --watch option stops detecting changes to markdown files.
