go run, add string value definition with space

[Tong Sun]

go run command-line-arguments

  -X definition
        add string value definition of the form importpath.name=value

I used to use this to override my variable values, in the form of

go run -ldflags="-X main.var1=val1 main.var2=val2"

Now, the new problem is that I need to have space in the string value definition. How can I do that please?

I've tried both the following cases:

go run -ldflags="-X main.var1='val 1' main.var2=\"val 2\""

but neither is working. 

Please help

Hi!

Not an expert at all, but it seems the format is "package-qualified.identifier=value", with value being able to just contain spaces out of the box, so running:

go run -ldflags="-X 'main.MyVar=this is a string'" main.go 

works for me. Note that for parsing the whole thing correctly, the whole equality should be surrounded by quotes (i.e. including the main.MyVar part)

Hope that helps!
