Templates

FileFlows utilizes the Scriban templating engine.

Syntax Overview

Scriban offers a robust syntax for template manipulation. Here are some key components:

Variables

Variables are denoted by enclosing them in double curly braces. For example:

{{ variable_name }}

Control Structures

Control structures like loops and conditionals are supported in Scriban. They follow a similar syntax to other programming languages:

{{ if condition }}
    // code block
{{ end }}

{{ for item in collection }}
    // code block
{{ end }}

Example Usage

Here's a simple example demonstrating how to use Scriban within FileFlows:

{{ difference = file.Size - file.Orig.Size }}
{{ percent = (difference / file.Orig.Size) * 100 | math.round 2 }}

Input File: {{ file.Orig.FullName }}
Output File: {{ file.FullName }}
Original Size: {{ file.Orig.Size | file_size }}
Final Size: {{ file.Size | file_size }}

{{- if difference < 0 }}
File grew in size: {{ difference | math.abs | file_size }}
{{ else }}
File shrunk in size by: {{ difference | file_size }} / {{ percent }}%
{{ end }}
