Scriban is a fast, powerful, safe and lightweight text templating language and engine for .NET, with a compatibility mode for parsing liquid templates.

// Parse a scriban template
var template = Template.Parse("Hello {{name}}!");
var result = template.Render(new { Name = "World" }); // => "Hello World!" 

Parse a Liquid template using the Liquid language:

// Parse a liquid template
var template = Template.ParseLiquid("Hello {{name}}!");
var result = template.Render(new { Name = "World" }); // => "Hello World!" 

The language is very versatile, easy to read and use, similar to liquid templates:

var template = Template.Parse(@"
<ul id='products'>
  {{ for product in products }}
    <li>
      <h2>{{ product.name }}</h2>
           Price: {{ product.price }}
           {{ product.description | string.truncate 15 }}
    </li>
  {{ end }}
</ul>
");
var result = template.Render(new { Products = this.ProductList });

NOTICE

By default, Properties and methods of .NET objects are automatically exposed with lowercase and _ names. It means that a property like MyMethodIsNice will be exposed as my_method_is_nice. This is the default convention, originally to match the behavior of liquid templates. If you want to change this behavior, you need to use a MemberRenamer delegate

• Very efficient, fast parser and a lightweight runtime. CPU and Garbage Collector friendly. Check the benchmarks for more details.
• Powered by a Lexer/Parser providing a full Abstract Syntax Tree, fast, versatile and robust, more efficient than regex based parsers.
  • Precise source code location (path, column and line) for error reporting
  • Write an AST to a script textual representation, with Template.ToText, allowing to manipulate scripts in memory and re-save them to the disk, useful for roundtrip script update scenarios
• Compatible with liquid by using the Template.ParseLiquid method
  • While the liquid language is less powerful than scriban, this mode allows to migrate from liquid to scriban language easily
  • With the AST to text mode, you can convert a liquid script to a scriban script using Template.ToText on a template parsed with Template.ParseLiquid
  • As the liquid language is not strictly defined and there are in fact various versions of liquid syntax, there are restrictions while using liquid templates with scriban, see the document liquid support in scriban for more details.
• Extensible runtime providing many extensibility points
• Precise control of whitespace text output
• Full featured language including if/else/for/while, expressions (x = 1 + 2), conditions... etc.
• Function calls and pipes (myvar | string.capitalize)
  • Custom functions directly into the language via func statement and allow function pointers/delegates via the alias @ directive
  • Bind .NET custom functions from the runtime API with many options for interfacing with .NET objects.
• Complex objects (javascript/json like objects x = {mymember: 1}) and arrays (e.g x = [1,2,3,4])
• Allow to pass a block of statements to a function, typically used by the wrap statement
• Several built-in functions:
  • arrays functions
  • date
  • html
  • maths functions
  • object
  • regex functions
  • string functions
  • timespan
• Multi-line statements without having to embrace each line by {{...}}
• Safe parser and safe runtime, allowing you to control what objects and functions are exposed

You can install the Scriban Extension for Visual Studio Code to get syntax coloring for scriban scripts (without HTML) and scriban html files.
