Faster-than-light, asynchronous, structured logger in Go with zero allocation count.

The following example creates a new logf logger and logs a message.

package main import ( "runtime" "github.com/ssgreg/logf" ) func main() { // The default channel writer writes to stdout using json encoder. writer, writerClose := logf.NewChannelWriter.Default() defer writerClose() logger := logf.NewLogger(logf.LevelInfo, writer) logger.Info("got cpu info", logf.Int("count", runtime.NumCPU())) }

The output is the following:

{"level":"info","ts":"2018-11-03T09:49:56+03:00","msg":"got cpu info","count":8}

TODO

Benchmarks:

• benchmarks descriptions
• non-parallel execution explanation
• scenario decomposition
• use zerolog object and array marshaller
• add checked logging for normal (not disabled) cases

Encoder:

• move to clone
• use EscapeString instead
