It would be great to have a quiet mode available, especially when running pmtiles as part of a CI/CD pipeline. Converting mbtiles to pmtiles in our pipeline currently produces ~4,000 lines of progress bar logs. This doesn't add anything of value in this context, and it would be helpful to have a way to turn that off.

This would a good addition. I'd prefer keeping progress the default and adding --quiet instead of making quiet the default and adding --progress. What program is earlier in your pipeline that creates MBTiles?

[ebbishop]

Agreed, it makes sense to have --quiet as an opt-in feature.

We're using tippecanoe to build mbtiles from a PostGIS db, then converting to pmtiles.

If you are using the maintained version of tippecanoe https://github.com/felt/tippecanoe you can generate PMTiles directly and don't need to use go-pmtiles at all.

• move to go 1.21 and structured logging https://pkg.go.dev/log/slog to aid this

Wondering if this might be supported soon? My use case is quieting the pmtiles serve command.

[bdon]

The issue above was regarding pmtiles convert, do you want pmtiles serve to output nothing at all? In most cases logging one line per served request with an HTTP status code is useful.

[jackiescanlon]

Yeah, a --quiet mode for pmtiles serve would be helpful. It is helpful to have the output for initial debugging but otherwise we'd love to quiet it down.

[bdon]

Piping the output to /dev/null could be one solution, unless you want to see only initialization messages, error messages etc and not info messages.

[jackiescanlon]

Yeah exactly, it'd still be good to see the other messages, just not the stream of served request messages.
