Function ConvertTo-DotEnv { <# .SYNOPSIS Converts array or hashtable to .env file format. .DESCRIPTION Converts array or hashtable to .env file format. Arrays are tested for either a list of name-value pair arrays or array of name and value column. For 2x2 arrays it will be treated as name-value pairs. To be able to pipe .PARAMETER DotEnvSource The input object that holds the content to be converted to .env file format. It can be a Dictionary/Hashtable or Array. .INPUTS DotEnvSource can be piped into the command instead of passing it as an argument. .OUTPUTS None. .EXAMPLE ConvertTo-CdfDotEnv -DotEnvSource @{ Name1 = 'Value1'; Name2 = 'Value2' } Name2=Value2 Name1=Value1 .EXAMPLE ,@( @('Name1', 'Value1'), @('Name2', 'Value2') ) | ConvertTo-CdfDotEnv # The array is treated as a 2x2 name-value pair array, mind the beginning comma to treat arrays as one parameter input Name2=Value2 Name1=Value1 .EXAMPLE ConvertTo-CdfDotEnv @( @('Name1', 'Name2', 'Name3', 'Name4'), @('Value1', 'Value2', 'Value3', 'Value4') ) # This array is treated as separate name and value column arrays Name1=Value1 Name2=Value2 Name3=Value3 Name4=Value4 .EXAMPLE ConvertTo-CdfDotEnv @( @('Name1', 'Name2'), @('Value1', 'Value2') ) # This array is treated as a 2x2 name-value pair array although that is likely not what was intended.
