Spark gen

Spark is a templating engine for go. It only provides components and property/attribute passing currently.

Installation

First, you need to install the generator package:

go install https://github.com/go-spark/spark-gen

Simple usage

spark-gen --dir="path/to/spark_templates_dir"

Other flags:

• --dir - path to the directory with spark templates
• --out - path to the output file. use @ to alias --dir path. default is @/dist/out.go
• --ext - extension for spark templates. default is st
• --pkg - package name for the generated code. default is dist

Usage

After generation just import the generated methods. hello.st will be converted to a Hello method under your outDir with the provided package name.

func main() {
	content := dist.Hello().Render()
	fmt.Println(content)
}

Component code

A component, for example hello.st looks like this:

!! label, id
<div :id>
  <p>{{ label }}</p>
  <st-input :placeholder="label" />
</div>

And input.st is imported with st-input, so let's create that too:

<input name="username" />

The first line of the component can contain two ! sign to define props. The label and id are passed to the component. The :id attribute automatically referred to the prop id in hello.st.

Import component from other directory

You can import code from other directory like this:

Component /utils/button.st

!! title
<button>
  {{ title }}
</button>

To import this component from any other Spark Template (st) you need to provide the full path to the component. You have to change the / to . and also add the st- prefix to help the compiler identify that you want to import a component.

<div>
  <st-utils.button title="Hello" />
</div>
