Echo Github Action Environment variables

I'm trying to dive in the GitHub action, and so on the .ylm files, and to understand the process I would like to echo some environment variables, such as ${{ github.repository }} or ${{ github.repository_owner }} or event secrets like ${{ secrets.GITHUB_TOKEN }} or any other, and in the output I'm getting ***.

Is there any way to force the output to show the actual values instead of the asterisks?

dev.ylm

name: Dev

on:
  workflow_dispatch:
  push:
    branches:
      - dev

env:
  BUILD_TYPE: core
  DEFAULT_PYTHON: 3.8

jobs:
  any_name:
    runs-on: ubuntu-latest
    steps:
      - name: Any Name Bash Test Step
        shell: bash
        run: |
          echo "GH_REPO: $GH_REPO"
          echo "GH_REPO_O: $GH_REPO_O"
          echo "GH_T: $GH_T"
        env:
          GH_REPO: ${{ github.repository }}
          GH_REPO_O: ${{ github.repository_owner }}
          GH_T: ${{ secrets.GITHUB_TOKEN }}

output

Run echo "GH_REPO: $GH_REPO"
  echo "GH_REPO_O: $GH_REPO_O"
  echo "GH_T: $GH_T"
  shell: /usr/bin/bash --noprofile --norc -e -o pipefail {0}
  env:
    BUILD_TYPE: core
    DEFAULT_PYTHON: 3.8
    GH_REPO: ***/core
    GH_REPO_O: ***
    GH_T: ***
GH_REPO: ***/core
GH_REPO_O: ***
GH_T: ***

You can't show secrets through echo otherwise there would be a huge security problem (even using env variables as an intermediary).

However, this will work with the other variables you used, the problem in your case seems to be related to the syntax. You should use run: echo "$GITHUB.REPOSITORY" and run: echo "$GITHUB.REPOSITORY_OWNER" to see them directly on your workflow.

Tip: You can identify most of the variables that can be shown with echo through the Github Context using run: echo "$GITHUB_CONTEXT" in your workflow.
