如何查看GoLand调试器是否在程序中运行?

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)
    }
    

    Running go run a.go will report delve false, and running
    dlv debug --build-flags='-tags=delve' a.go will report delve true.

    You'll have to pass that flag somewhere in the GoLand user interface. I'm not familiar with GoLand, so I can't really help you with that part specifically.


    Alternatively, you can use delve's set command to manually set a variable after starting the debugger.
