hey! i'm using pulumi for some personal things to get a handle on it and I'm having a heck of a time in Go from converting various

Output

values to concrete values. everything I find online seems to call methods that don't exist for me or don't seem to work as the stuff I find online says. currently, I have an output named

projectName

on one stack, and I use a stack reference to get that value from from the other stack as a

pulumi.AnyOutput

and then use that with

.AsStringOutput()

to give me a

pulumi.StringOutput

(it's a string, this seems to work fine). however, i'm trying to take that value and pass it into a

digitalocean.LookupProject

where the

Name

arg expects

*string

. I've tried a bunch of iterations, including

ApplyT

with a

func(projName string) *string

, but I just can't seem to get the value the lookup expects. I'm also having a hard time taking

pulumi.StringOutput

to

string

at times as well. it sounds like it's supposed to be

ApplyT

, but that just returns an output that gets me back into the same

pulumi.StringOutput

. anyone have some tips for me?

Anything with "Output" in its type is not available now, only in the future. You either need to wait for it, or use it in a callback that gets called later, when it's available.

that's the part i'm having trouble with =/ the docs say it's supposed to support "lifting" but the only example it gives is pulling some element from an array, but that same idea doesn't seem to work with getting a

string

from a

pulumi.StringOutput

Yes, the string is not available yet, you cannot get at it.

there has to be some way for me to get it, though. otherwise I could never use an output as a lookup for a resource, right?

Did you read the link I posted above, and the code snippet with ApplyT()?

yeah, that's what i've been trying

⬅️ Post your code. Use the "Create a text snippet" function in Slack's "+" menu.

I've tried a lot of iterations of trying to get a value for

Name

, which requires a

*string

.

Ah, if there's an Output version of a parameter, that definitely helps!

yup! i'd definitely like to figure out this problem I'm having at some point, though. the way things are explained it sounds like what I've been doing should work, but it's not. so it makes me feel like the go code is some weird edge case

For the ApplyT() in that code you posted: you should need the ApplyT() in this case. Because the Name parameter should take an output, you don't need to convert the name output. You should be able to use it directly. It does look like everything's good...

yeah, if i get rid of the

ApplyT

on there it'll complain that it can't assign

pulumi.StringOutput

or

pulumi.StringPtrOutput

(I tried both) to a

*string

But nothing in there is a string, is it?

Name

should be an Input, and

projName

is an Output. I guess my golang is not up to this problem.. I should stick with typescript...

i do feel like it's some weirdness with the go type system. there are

pulumi.Output

values, but those are subdivided into

pulumi.StringOutput

, etc. and then if I try to convert a

pulumi.StringOutput

to a

string

by just doing something like

var myString string = myStringOutput

it sounds like that should work, but it doesn't

No, that won't ever work. The StringOutput isn't yet known, it's a promise / future. You cannot convert it to a string.

yeah, that's what i meant. like somehow make it block and return a

string

just doing something like

var myString string = myStringOutput

it sounds like that should work, but it doesn’t

yeah that unfortunately won’t ever work. You can’t assign an

StringOutput

to a

string

unless you are inside the

ApplyT

. so as an example:

// here myOutputValue is always an output
myOutputValueApplyT(func(myOutput string) string {
  // here, we are inside the ApplyT function, so we have resolved the value and now it's a string
  fmt.Println(myOutput)
}
