Package -

CircleCI platform SPM swift


Amazing template language for web development used n Swift Squirrel web framework (see: Swift Squirrel)


Add NutView as dependency in your Package.swift

// swift-tools-version:4.0

import PackageDescription

let package = Package(
    name: "Your app",
    products: [
        // Your products
    dependencies: [
        .package(url: "", from: "0.1.0"),
        // Other dependencies
    targets: [
            name: "Your Targer",
            dependencies: [..., "NutView"]),

And in source add import line

import NutView


NutView uses special swift-like syntax in .nut files which provide great readability for swift developers.

Directory structure

NutView use two important directories.

  • First (default name: "Nuts") contains another three subdirectories with .nut files (Views, Layouts, Subviews). In theese three directories you can add another directories or add and edit .nut files.
  • Second (defualt name: "Fruits") contains generated files from your .nut files. (Don't change content of this directory)

You can change this directories with

NutConfig.nuts = "SomeDir/SomeAnotherDir1/NutsDir"
NutConfig.fruits = "SomeDir/SomeAnotherDir2/FruitDir"


Contains page specific content. For example if we have blog and we want to have page with certain post our view will contain only post information and not layout, header, footer etc...


Contains reusable parts of page. For example header or footer.


This is actualy our web layout. You can refer to layout from Views which pin View content to Layout at the place where is \View(...)


Commands starts with \ symbol. You can escape \ symbol with \\

|Name|Syntax|Semantic| |:--|:--|:--| |Expression|\(<expression>)| Evaluates expression in parentheses and escapes html characters| |Raw expression| \RawValue(<expression>)| Evalutes expression| |Block end|\}|Indicates block end in if, for statements| |If
Else if
Else|\if <expression> {
\} else if <expression> {
\} else \{ | If expression is true run commands in given block otherwise run else if|else block if exists| |If let
Else if let|\if let <variableName> = <expression> {
\} else if let <variableName> = <expression> { | If expression is not nil store result in variableName and run commands in given block otherwise run else if|else block if exists| |Subview|\Subview("<name>")|Add content of given subview postion of this command. Note: name must be static string. You can not use expression. name is using dot notation so instead of MySubviewSubdirectory/Mysubview.nut write MySubviewSubdirectory.Mysubview.nut.| |For|\for <variable> in <Array>
\for (<key>, <value>) in <Dictionary>| Iterates over array([Any]) or dictionary([String: Any])| |Date| \Date(<expression>)
\Date(<expression>, fromat: <expression>) | Evaluates expression and print date in given format. If format is not set, NutView use default date format specified in NutConfig.dateDefaultFormat: String { set get }| |Layout|\Layout("<name>")| Only available in Views. Reffer View to Layout. Must not be more than one occurence of this command in one is using dot notation so instead of MyLayoutSubdirectory/MyLayout.nut write MyLayoutSubdirectory.MyLayout.nut.| |Title| \Title(<expression>) | Only available in Views. Set <title><\title> header of html document |View|\View()|Only available in Layouts. Indicates where to place View|

Note: For evaluating expressions we use Evaluation



import NutView

let indexView = View(name: "Index") // We don't have to write .nut 
let indexContent = try indexView.getContent()
print(indexContent) // prints generated content of index

struct PostData {
    let title: String,
    let body: String,
    let isNew: Bool
let postData = PostData(title: "Squirrels", body: "Squirrels are best!", isNew: false)
let postView = try View(name: "Posts.Post", with: postData) // note we write . instead of /
let postContent = try postView.getContent()
print(postContent) // prints generated content of page with given data

let postContentData = try postView.present() // Data representation of view
