[WassimKallel]

Scope

• Added initial provider
• Intended to be published as Think-iT-Labs/dirhash in Terraform registry
• Templates for provider documentation were also added

Usage

data "dirhash_sha256" "example" {
  directory = "/path/to/directory"
  ignore = [
    "glob_pattern_1/*",
    "glob_pattern_2/*"
  ]
}
output "directory_sha256_checksum" {
  description = "the Output SHA256 Checksum for the directory"
  value       = data.dirhash_sha256.example.checksum
}

there's code that might cause a runtime panic

[NabilHouidi]

are we really sure that only interface of type string can reach here? failing that the code will panic.
example from go playground:

package main

import "fmt"

func main() {
	var d interface{}
	d = 45
	fmt.Println(d.(string))
}

when running the code above it panics:

panic: interface conversion: interface {} is int, not string

goroutine 1 [running]:
main.main()
	/tmp/sandbox615016875/prog.go:10 +0x2e

Program exited.

Yes, we are @NabilHouidi Terraform generates it that way based on the schema

[NabilHouidi]

there's still a calculate here
