So I'm working on migrating some old modules to 0.13; I use the following syntax in my projects in 0.12

apiVersion: garden.io/v1
kind: Project
name: project
defaultEnvironment: local
dotIgnoreFile: .gitignore

variables:
  POSTGRES_USERNAME: postgres
  POSTGRES_DATABASE: postgres
  POSTGRES_PASSWORD: postgres
  POSTGRES_CONNECTION_STRING:  postgres://${var.POSTGRES_USERNAME}:${var.POSTGRES_PASSWORD}@postgres-edge-api-cc:5432/${var.POSTGRES_DATABASE}?schema=public

This used to work in Garden 0.12 which was nice because I could build variables on the flight in the project level variables; now I can't because of the following error

garden validate

Which is pretty sad; I don't see a reason why this should have been removed? I tested doing the string templating in the environment level and it worked; which is pretty bad for my use case because I would need to repeat variables in N environments where the value is always going to be the same.... Workaround: Not use variable substitution on the project level but just hardcode the valuess. 😢

@chilly-gigabyte-83853 I don’t think that answers the variables interpolation problem?

Hi @bright-policeman-43626, I am sorry, I was convinced Thor's answer was covering this. I am a bit puzzled by how the first example was working on 0.12, it could have been a feature that should have been a bug, since I don't recall being able to reference variables from within the same block. 🤔 It seems though that you are absolutely right and that's not possible in 0.13. If I may suggest a way to reduce repetition, it would be to define:

POSTGRES_USERNAME: postgres
POSTGRES_DATABASE: postgres
POSTGRES_PASSWORD: postgres

on the

project.variables

level and

POSTGRES_CONNECTION_STRING

as defined above in the action's

variable

block. If the connections parameters change across environments, you could also move the definitions above under

environments[].variables

so you can tweak those based on your env.

@bright-policeman-43626 I tested your code with the latest acorn-edge version and it does not work:
