I'm using Python with the Automation API I haven't been able to reference modules that are referring to stack metadata because these are initialized outside of the stack initialization Is there a way to package code with an inline program so that it's used consistently across all stacks?
For example:
Copy code
config = pulumi.Config()
environment = config.require('environment')
project_name = pulumi.get_project()
AutoTag(environment)
I need these lines in every single stack I'm creating

I think your normal language constructs would work here. Put that code in a function, call it in the normal way from each project...

Right, but the lines after this would be different 🤔

So only those lines would be in the function...?

Each stack would provision it's own resources The config and tagging would be used everywhere but the resources would be different depending on the stack
If I could chain functions that my work but classes haven't worked for me

Are you used either aws:defaultTags or StackTransformation? Both of those can be set up before you create the resources, and then be forgotten about. Should work with this style of code.

I'm using 
StackTransformation
Is it possible to load a 
StackTransformation
during stack creation?

It is configured in runtime, before any resources are created.
So it should always apply.

@billowy-army-68599 do you know if it's possible to load 
StackTransformation
into 
LocalWorkspaceOptions
or anytime before 
stack.up
?

I’m not sure what exactly a StackTransformation is - do you have a doc reference? But in general, no. Concepts available from within a pulumi program are not available outside of the program itself.
I’m kinda struggling to wrap my head around what the exact issue is… what are you hoping to achieve?

Thanks for the link @little-cartoon-10569. Today I learned! Okay but yeah this is still something you would call from within your 
InlineProgram
using automation api.
Going back to tenwit’s original suggestion though… why can’t these lines be a function that is called from within each stack?
Copy code
def tag_env():
    config = pulumi.Config()
    environment = config.require('environment')
    project_name = pulumi.get_project()
    AutoTag(environment)

def my_inline_pulumi_program():
    tag_env()
    ...

def my_other_inline_program():
    tag_env()
    ...
I feel like I’m missing something

Yea, it's not even each stack, it's just each program.. it looks good to me...

Is it possible to run multiple inline programs in the same stack?

Programs contain stacks, not vice versa...

stacks are usually used to denote environments like staging, dev, prod of the same program.
that doesn’t necessarily have to be the case. for instance, in the little webapp i built, i use stacks to just pump out different resources from the same program: https://github.com/komalali/self-service-platyform/blob/main/app/sites.py#L77-L92

When you initialize a stack you pass the inline program. That's what I'm referring to

If you pass in a different function to the stack it will override your program and deploy the new program. So no, you cannot run multiple inline programs in a stack.
but your inline program function can call other functions
