retab

retab ➡️

Simplify your config management with retab. This tool transforms .retab files (using hcl syntax)into YAML or JSON, allowing you to write in HCL and enjoy the readability benefits of tab indentation.

⭐️ Key Features

1. Compile: Transform .retab/*.retab files into .yaml or .json files.
2. Format: Format .retab/*.retab files for clearer and accessable indentation.

🛠️ Install from the Source

go install github.com/walteh/retab/cmd/retab

🚀 Quick Start

1. Create a .retab/*.retab file:

BRANCH = "main"

gen "hello-world-github-workflow" {
	path   = "./.github/workflows/hello-world.yaml"
	schema = "https://raw.githubusercontent.com/SchemaStore/schemastore/master/src/schemas/json/github-workflow.json"
	data = {
		name = "hello-world"

		on = {
			push = {
				branches = [BRANCH]
			}
		}

		jobs = {
			say-hello = my_custom_type.my_custom_name.another_custom_type.do_whatever_you_want
		}
	}
}

my_custom_type "my_custom_name" {
	another_custom_type {
		do_whatever_you_want = {
			runs-on = "ubuntu-latest"
			steps = [
				{
					name = "Checkout"
					uses = "actions/checkout@v4"
					with = {
						fetch-depth = 1
					}
				},
				{
					name = "Run tests"
					run  = <<SHELL
							echo "Hello world"
						SHELL
				}
			]
		}
	}
}

1. Format with retab fmt:

retab fmt

1. Compile with retab gen:

retab gen

This generates a .yaml or .json file based on your .retab/*.retab file.

# code generated by retab. DO NOT EDIT.
# join the fight against yaml @ github.com/walteh/retab

# source: ".retab/hello-world.retab"

name: hello-world
"on":
    push:
        branches:
            - main
jobs:
    say-hello:
        runs-on: ubuntu-latest
        steps:
            - name: Checkout
              uses: actions/checkout@v4
              with:
                fetch-depth: 1
            - name: Run tests
              run: |
                echo "Hello world"
