If I do not specify ToLower() on each prefix and the name the regex fails, with reason, since the module is not forcing all input values ToLower.

Would be ideal if the module did the legwork.
In this way I can pass name and prefixes that may contain capitals, acceptable for other resources, but will get lower cased when used for storage account.

It unclear to me how to override the random suffix generation as well as how to change the separator used.

In my case for storage accounts I rather not have 0 as separator, in fact id like no separator at all.
The following does not work

module "csazname_storage_account" {
  source    = "gsoft-inc/naming/azurerm//modules/storage/storage_account"
  name      = lower(var.rg_rs_basename)
  prefixes  = ["st", lower(var.rg_project), lower(var.rg_projecttype)]
  separator = ""
}

This results in An argument named "separator" is not expected here.

Setting the suffixes to [] results in regular generation, since its the default.
Setting the suffixes to null results in error
setting suffixes to [""] result in no suffix but a separator is still present

Appreciate any assistance

Underscore is a valid character for resource groups

The following fails
RG-TST-DEV-Main_NodePool-j4536dd634745qk
RG_TST_DEV_Main_NodePool-j4536dd634745qk

^[a-zA-Z0-9]{1}[a-zA-Z0-9-]*$ should thus become ^[a-zA-Z0-9]{1}[a-zA-Z0-9-_]*$

Hi - these set of modules look really useful for programmatically naming resources . I am seeing an issue however on Windows with terraform 0.13.7 when i run terraform init with just say the module for the resource group. The init appears to get stuck in a loop?

Issue here

Something I am doing wrong or a bug? Any help assistance would be appreciated.

Thanks
