Pass environment variables to reusable workflow without using 1 to 1 inputs - environment-variables

Question

Right now, if I want to pass a environment variable to a reusable workflow I have to do something like this:
name: Reusable workflow
on:
workflow_call:
inputs:
my_env_var:
required: false
type: string
env:
my_env_var: ${{ inputs.my_env_var }}
However, for this I first need to define as an input each environment variable I want to pass. This works, but having to hard code the environment variables makes my reusable workflows less generic. Is there a way to pass envs without having to define them one by one? I was thinking on something like this:
name: Calling reusable workflow
on:
workflow_dispatch:
jobs:
push-image-dev:
uses: ./.github/workflows/my-reusable-workflow.yml
with:
input1: ...
input2: ...
env:
env1: ...
env2: ...
However, I have been reading some documentation and I don't think that exists. Is there any other way of doing it, as inheriting env variables or creating a single input which is a variable dictionary, which is later parsed and sets all the env vars in the reusable workflow?

Answer 1

I created this simple logic which allows me to pass all the environment variables I want on a 1:N relationship with respect to inputs. I created an input which expects a list of environment variables, formatted as "env=value", and which is later converted to environment variables in a step inside the workflow.
Calling the workflow:
name: Calling reusable workflow
on:
workflow_dispatch:
jobs:
my-job:
uses: ./.github/workflows/my-reusable-workflow.yml
with:
env_vars: |
env1=value1
env2=value2
env3=value3
Workflow definition:
name: My reusable workflow
on:
workflow_call:
inputs:
env_vars:
description: List of environment variables to set up, given in env=value format.
required: false
type: string
jobs:
my-job:
runs-on: ubuntu-latest
steps:
- name: Set environment variables
if: ${{ inputs.env_vars }}
run: |
for i in "${{ inputs.env_vars }}"
do
printf "%s\n" $i >> $GITHUB_ENV
done
