+# go-debug
+
+ Conditional debug logging for Go libraries.
+
+ View the [docs](http://godoc.org/github.com/tj/go-debug).
+
+## Installation
+
+```
+$ go get github.com/tj/go-debug
+```
+
+## Example
+
+```go
+package main
+
+import . "github.com/tj/go-debug"
+import "time"
+
+var debug = Debug("single")
+
+func main() {
+  for {
+    debug("sending mail")
+    debug("send email to %s", "tobi@segment.io")
+    debug("send email to %s", "loki@segment.io")
+    debug("send email to %s", "jane@segment.io")
+    time.Sleep(500 * time.Millisecond)
+  }
+}
+```
+
+If you run the program with the `DEBUG=*` environment variable you will see:
+
+```
+15:58:15.115 34us   33us   single - sending mail
+15:58:15.116 3us    3us    single - send email to tobi@segment.io
+15:58:15.116 1us    1us    single - send email to loki@segment.io
+15:58:15.116 1us    1us    single - send email to jane@segment.io

+15:58:15.620 4us    4us    single - send email to jane@segment.io
+15:58:16.123 503ms  503ms  single - sending mail
+15:58:16.123 7us    7us    single - send email to tobi@segment.io
+15:58:16.123 4us    4us    single - send email to loki@segment.io
+15:58:16.123 4us    4us    single - send email to jane@segment.io
+15:58:16.625 501ms  501ms  single - sending mail
+15:58:16.625 4us    4us    single - send email to tobi@segment.io
+15:58:16.625 4us    4us    single - send email to loki@segment.io
+15:58:16.625 5us    5us    single - send email to jane@segment.io
+```
+
+A timestamp and two deltas are displayed. The timestamp consists of hour, minute, second and microseconds. The left-most delta is relative to the previous debug call of any name, followed by a delta specific to that debug function. These may be useful to identify timing issues and potential bottlenecks.
+
+## The DEBUG environment variable
+
+ Executables often support `--verbose` flags for conditional logging, however
+ libraries typically either require altering your code to enable logging,
+ or simply omit logging all together. go-debug allows conditional logging
+ to be enabled via the __DEBUG__ environment variable, where one or more
+ patterns may be specified.
+
+ For example suppose your application has several models and you want
+ to output logs for users only, you might use `DEBUG=models:user`. In contrast
+ if you wanted to see what all database activity was you might use `DEBUG=models:*`,
+ or if you're love being swamped with logs: `DEBUG=*`. You may also specify a list of names delimited by a comma, for example `DEBUG=mongo,redis:*`.
+
+ The name given _should_ be the package name, however you can use whatever you like.
