tracerx
Tracerx is a simple tracing package that logs messages depending on environment variables. It is very much inspired by git's GIT_TRACE mechanism.
Installation
go get github.com/rubyist/tracerx
Example
tracerx.DefaultKey = "FOO"
tracerx.Printf("send message")
tracerx.PrintfKey("BAR", "do a thing")
t := time.Now()
// Do some stuff
tracerx.PerformanceSince("BAR", "command x", t)
This example will send tracing output based on the environment variables FOO_TRACE and BAR_TRACE.
The values control where the tracing is output as follows:
unset, 0, or "false": no output
1, 2: stderr
absolute path: output will be written to the file
3 - 10: output will be written to that file descriptor
If an associated BAR_TRACE_PERFORMANCE is set to 1 or "true", the PerformanceSince line will
output timing information.
Keys can also be disabled. See the GoDoc for full API documentation.
