问题
In C# the executing program can detect if it's running in the debugger using:
System.Diagnostics.Debugger.IsAttached
Is there an equivalent in Go? I have some timeouts which I would like to be disabled while I am stepping through the code. Thanks!
I am using the GoLand debugger.

As far as I know, there is no built-in way to do this in the manner you described. But you can do more or less the same using build tags to indicate that the delve debugger is running. You can pass build tags to dlv
with the --build-flags
argument. This is basically the same technique as I described in How can I check if the race detector is enabled at runtime?
isdelve/delve.go
// +build delve
package isdelve
const Enabled = true
isdelve/nodelve.go
:
// +build !delve
package isdelve
const Enabled = false
a.go
:
package main
import (
"isdelve"
"fmt"
)
func main() {
fmt.Println("delve", isdelve.Enabled)
}
In Goland, you can enable this under 'Run/Debug Configurations', by adding the following into 'Go tool arguments:'
-tags=delve
If you are outside of Goland, running go run a.go
will report delve false
, if you want to run dlv on its own, use
dlv debug --build-flags='-tags=delve' a.go
; this will report delve true
.
Alternatively, you can use delve's set
command to manually set a variable after starting the debugger.
