# go-debug
|
||
|
|
|
||
|
|
This library provides a very simple method for compile-time or runtime determined debug checks, set using build tags.
|
||
|
|
|
||
|
|
The compile-time checks use Go constants, so when disabled your debug code will not be compiled.
|
||
|
|
|
||
|
|
The possible build tags are:
|
||
|
|
|
||
|
|
- "debug" || "" = debug determined at compile-time
|
||
|
|
|
||
|
|
- "debugenv" = debug determined at runtime using the $DEBUG environment variable
|
||
|
|
|
||
|
|
An example for how this works in practice can be seen by the following code:
|
||
|
|
|
||
|
|
```
|
||
|
|
func main() {
|
||
|
|
println("debug.DEBUG() =", debug.DEBUG())
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
```
|
||
|
|
# Debug determined at compile-time, it is disabled
|
||
|
|
$ go run .
|
||
|
|
debug.DEBUG() = false
|
||
|
|
|
||
|
|
# Debug determined at compile-time, it is enabled
|
||
|
|
$ go run -tags=debug .
|
||
|
|
debug.DEBUG() = true
|
||
|
|
|
||
|
|
# Debug determined at runtime, $DEBUG is not set
|
||
|
|
$ go run -tags=debugenv .
|
||
|
|
debug.DEBUG() = false
|
||
|
|
|
||
|
|
# Debug determined at runtime, $DEBUG is set
|
||
|
|
$ DEBUG=y go run -tags=debugenv .
|
||
|
|
debug.DEBUG() = true
|
||
|
|
```
