Turbx

A Fast and Easy To Use View Engine, Compiled In Go.

Note: this is the info for the Go module. Click here to find info on the NodeJS module.

---

Notice: the Go module v2 is ready, but the NodeJS module v2 has Not been setup yet. The html templates between v1 and v2 are slightly different. For the NodeJS module, you should continue to use v1. This is only a pre-release of v2 for Go.

Whats New

• New rebuild of the compiler to replace my old spaghetti code (and create new spaghetti code)
• Performance and Stability improvements.

Installation

sudo apt-get install libpcre3-dev

go get github.com/AspieSoft/turbx/v2

Setup

package main

import (
  turbx "github.com/AspieSoft/turbx/v2/compiler"
)

func Test(t *testing.T){
  defer turbx.Close()

  turbx.SetConfig(turbx.Config{
    Root: "views",
    Static: "public",
    Ext: "html",
    IncludeMD: true,
    DebugMode: true,
  })

  // note: if 'turbx.SetConfig' is never called, you will need to run 'turbx.InitDefault' in its place
  // this runs some initial code that cannot run before the config is set
  turbx.InitDefault()

  startTime := time.Now().UnixNano()

  html, path, comp, err := turbx.Compile("index", map[string]interface{}{
    "@compress": []string{"br", "gz"}, // pass the browser compression options from the client
    "@cache": true,

    "key": "MyKey",
    "name": "MyName",

    "$myConstantVar": "this var will run in the precompiler",

    "test": 1,
    "var": "MyVar",
    "list": map[string]interface{}{
      "key1": "value1",
      "key2": "value2",
      "key3": "value3",
    },
  })

  if err != nil {
    // this method will only log errors if debug mode is enabled
    turbx.LogErr(err)
    return
  }

  endTime := time.Now().UnixNano()


  // a path will be provided if we precompiled a static file
  // you can send this file directly to the user (it will automatically choose a compressed file as needed)
  // if there is no path (path == ""), we will have an html output instead (which will also be compressed as needed)
  if path != "" {
    html, err = os.ReadFile(path)
    if err != nil {
      turbx.LogErr(err)
      return
    }
  }

  if comp == 1 {
    if html, err = goutil.BROTLI.UnZip(html); err != nil {
      turbx.LogErr(err)
      return
    }
  }else if comp == 2 {
    if html, err = goutil.GZIP.UnZip(html); err != nil {
      turbx.LogErr(err)
      return
    }
  }

  fmt.Println("----------")
  fmt.Println(string(html))
  fmt.Println("----------")

  fmt.Println(float64(endTime - startTime) / float64(time.Millisecond), "ms")
}

Usage

<!-- this is a comment -->
/* this is also a comment */
// this is an inline comment


<!-- output a variable with escaped HTML -->
{{title}}

<!-- output a variable and allow HTML -->
{{{content}}}

<!-- output a variable with a fallback -->
{{title|name|'Default Title'}}


<!-- output a variable as an attribute (this method will remove the attribute if the value is undefined) -->
<a {{href="url"}}>Link</a>

<!-- this is a shortcut if the attribute name matches the variable name -->
<a {{="href"}}>Link</a>


<!-- you can safely insert object keys (if an object is undefined, this will return blank, and will Not crash) -->
{{obj.key}}

<!-- use dot notation for array indexes -->
{{arr.0}}

<!-- use the value of the "key" var as the key of "obj" -->
{{obj[key]}}
{{obj[myVar]}}


<!-- using vars as if they were constant -->
{{$normalVal|'make this constant anyway, even if not sent as a constant'}}


<!-- functions start with an _ -->
<_if var1 & var2="'b'" | var2="'c'" | !var3 | (group & group1.test1)>
  do stuff...
<_else !var1 & var2="var3" | (var3=">=3" & var3="!0")/>
  do other stuff...
<_else/>
  do final stuff...
</_if>

<_each myObj as="value" of="key">
  {{key}}: {{value}}
</_each>

<!-- 'if/else' statements and 'each' loops are a special kind of function, and do not need the '_' prefix -->
<if test>
  {{test}}
<else/>
  no test
</if>

<each myObj as="value" of="key">
  {{key}}: {{value}}
</each>


<!-- A component is imported by using a capital first letter -->
<!-- The file should also be named with a capital first letter -->
<!-- args can be passed into a component -->
<MyComponent arg1="value 1" arg2="value 2">
  Some body to add to the component
</MyComponent>

<!-- component without a body -->
<MyComponent arg1="value"/>

<!-- file: MyComponent.html -->
{{arg1}} - {{arg2}}
<h1>
  {{{body}}}

  <!-- escaped html body -->
  {{body}}
</h1>


<!-- file: layout.html -->
<html>
  <head></head>
  <body>
    <header></header>
    <main>
      <!-- Insert Body -->
      {{{body}}}
    </main>
    <footer>
  </body>
</html>
