strfry 1.1.0 beta series:
I'm working on a new release of strfry and there are some beta releases tagged in case anyone wants to give them a try. There are lots of changes in the queue. I'll write them up in more detail soon.
For now here's a small new feature in 1.1.0-beta4: --range option for sync. Basically it's a convenience feature for specifying since/until in your filter. Examples:
strfry sync wss://blah.com --range 1h-
^^ sync just last hour of notes
strfry sync wss://blah.com --filter '{"kinds":[0]}' --range 1Y-6M
^^ sync kind 0 events between 1Y and 6M old
This is especially useful for "paginating" big syncs. You can first do 2M-1M, then do 3M-2M, then 4M-3M, etc.
