will log4rs support file size control and rolling file ? about log4rs HOT 10 CLOSED

Yep, appender configuration's pretty rudimentary right now, but log rotation is definitely something I want to add.

I like this lib. But log rotation is a rigid requirement for me. Maybe I should not ask , but I really want to know is this requirement in schedule already?

It's part of some expansion I have been meaning to do. I'll hack on it over the weekend.

That's great，I am looking forward to it

Now that log4rs 0.4 is released, I'm going to start tackling this. I think I'll probably work on it in a separate repo/crate initially until the API gets worked out, but then move it in since it's such a core concept.

While you're thinking about the API, it would be nice to support external rotation utilities like logrotate. I think that basically means exposing a method which causes appenders to reopen their log files.

from log4rs.

I was planning on having a similar setup to Logback, where there's a "triggering policy" that decides when the log should roll, and a "rotation policy" that decides what to do at that point. I think it should be possible to write a triggering policy that the logback postrotate command can poke, and a rotation policy that just closes and reopens the file.

That sounds great!

I'm working on this here: https://github.com/sfackler/log4rs-rolling-file

Not quite ready for a release yet, but the basics are there.

This is now on crates.io: https://crates.io/crates/log4rs-rolling-file

It's still missing some functionality like TimeBasedRollingPolicy which is a bit weird from an API perspective but probably the most common policy people actually use, so I'm going to keep it in a separate crate for now until that gets worked out.
