Debug print perform that may be negated at compile time – Getting Assist


i wish to place print debug messages in my code however i solely need them to be compiled in if debug symbols are included at compile time, what’s one of the simplest ways to go about doing this?

tldr; compile debug bin print debug message, compile launch bin compiler ignores debug messages.

The best solution to obtain this in Go is by utilizing construct tags with two separate recordsdata in the identical package deal listing.

1. Create a file named debug_on.go:

The primary line have to be the construct tag:

//go:construct debug

package deal major

import “log”

func DebugLog(format string, v …any) { log.Printf(“[DEBUG] “+format, v…) }

2. Create a file named debug_off.go:

The primary line have to be:

//go:construct !debug

package deal major

func DebugLog(format string, v …any) {}

3. Utilization in code:

Simply name DebugLog(“your message: %s”, worth) in your major code.

4. The best way to compile or run:

For Debug mode (consists of debug messages):
go run -tags debug .
go construct -tags debug -o app-debug

For Launch mode (debug perform turns into an empty no-op and will get optimized away):
go run .
go construct -o app-release
