class.BareName at beginning of line with one tab adds extra whitespace

[washamdev]

Can anyone help me address this problem? The template contains code at one tab indentation. I've got a line that begins with {{ class.BareName }} on a new line:

But when that template is rendered, it contains an extra tab:

How do I get that line to start with the right amount of indentation?

Just to be clear, we use four spaces as tabs.

Checkout this section of docs

Basically, you need to add a '-' to supress the extra whitespace.

{{ - class.BareName }}

[washamdev]

That removes all whitespaces and new lines before that line though.

I have another idea, maybe the class name contains whitespaces? I would try: {{ class.BareName | String.Strip }}

[gregveres]

or maybe add a {{ }} ahead of the {{ - class.BareName }} to ensure that the new line isn't stripped. In my templates, I make sure there are no indentations in the main body of my template. If I need to output something from a function, I return it as a string that the main body prints out. This way I control all the indentation from the main body.

Like this:

{{- # Helper classes }}
{{- func ImportType(type)
    useType = Type.Unwrap(type)
    if (useType.ArrayType != null) 
      useType = useType.ArrayType
    end
    if (type.IsEnum) 
      path = "@skycourt/api/enums"
    else
      path = "./" | String.Append useType.Name
    end
    if ((useType.Attributes | Array.Filter @AttrIsExportToTypescript).size > 0)
        ret "import { " | String.Append useType.Name | String.Append " } from '" | String.Append path | String.Append "';\r"
    end
    ret null
    end
}}
{{- func AttrIsExportToTypescript(attr)
    ret attr.Name | String.Contains "ExportToTypescript"
    end
}}

{{- # output classes }}
{{ $barrelFile = "" }}
{{- for class in data.Classes | Symbols.ThatHaveAttribute "ExportToTypescript" | Array.Concat (data.Classes | Symbols.ThatHaveAttribute "ExportToTypescriptWithKnockout") | Array.Sort "Name"
        capture output }}

{{- for type in (class | Type.AllReferencedTypes)}}
    {{- ImportType type}}
{{-end}}

export interface {{class.Name}}{{if class.HasBaseClass}} extends {{class.BaseClass.Name; end}} {
  {{- for prop in class.Properties | Symbols.ThatArePublic }}
  {{ prop.Name | String.ToCamelCase }}: {{prop | Custom.ToTypeScriptType }}{{if !for.last}},{{end}}
  {{-end}}
}
{{- end}}

@gregveres I didn't need the {{-. Just using {{ worked, as long as I added the blank entry first. So {{ }}{{ class.BareName }} was the winner! Thank you! Is this a bug or expected behavior?

[NeVeSpl]

Obviously, it is not expected, but Scriban is responsible for that part. NTypewriter uses Scriban v5.5, and apparently, there was some fix in version 5.6 of scriban/scriban#483 related to not intended indentation.

[gregveres]

Based on the documentation, I would say it is working as expected. But if it is a bug, then it is a bug in Scriban, not in NTypewriter. You could as on their github site.
