create a slug function for terraform core

[ryanpodonnell1]

Terraform Version

Terraform v1.9.8
on linux_amd64

Use Cases

I would like to request a slug function be added. Currently there is a great provider that offers this but feels fairly useful for things like templating dynamic vars which dont allow spaces or special chars in the key or URL creation

example:

variable "custom_object" {
default = {
"a value (1)" = ["one","two"]
"a value (2)" = ["three"]
      }
}
....
locals {
slugify_custom_object                 = { for k2, v2 in var.custom_object : slug(k2) => jsonencode(v2) }
template_string = "template_me: ${a-value-1}"
template = try(templatestring(local.template_string,local.slugify_custom_object),null)
}

Attempted Solutions

requires a custom/3rd party provider

variable "custom_object" {
default = {
"a value (1)" = ["one","two"]
"a value (2)" = ["three"]
      }
}
....
locals {
slugify_custom_object                 = { for k2, v2 in var.custom_object : provider::slugify::slug(k2) => jsonencode(v2) }
template_string = "template_me: ${a-value-1}"
template = try(templatestring(local.template_string,local.slugify_custom_object),null)
}
