Jet Template Engine for GO 
Jet is template engine developed to be easy to use, powerful, dynamic and very fast. Very fast without pre-compilation and dynamic features, yes this is possible.
Support template inheritance, with extends, and block imports, fast writer, auto escapee, and many more features.
Jet is based on text/template, i used part of the lexer and part of the parser code.
Intellij Plugin
If you use intellij there is a plugin available in https://github.com/jhsx/GoJetPlugin There is also a very good Go plugin for intellij ("https://github.com/go-lang-plugin-org/go-lang-idea-plugin") GoJetPlugin + Go-lang-idea-plugin = Happiness :D
Features
- Template Inheritance
- File based
- Auto-escape
- Complex Expression
- Tests and Benchmarks
- Fast and light
- Simple syntax and simple to use
- Descriptive error messages with filename and line while parsing or evaluating templates
Examples
Simple
Hey {{name}}!
No Escape {{ "<a href=\""\">Link</a>" |unsafe}}Extends
{{extends "common/layout.jet"}}
{{block Content}}
{{.PageHeader}}
{* this is a comment *}
{{.PageContent |unsafe}}
{{end}}Range
{{extends "common/layout.jet"}}
{{block Content}}
{{.PageHeader}}
{{range .Result}}
<div>
<div class="result-header">{{.Title}}</div>
<div class="result-description">{{.Description}}
<a href="{{.Linkme()}}">Read more</a></div>
</div>
{{end}}
{{end}}Import Extends Yield
{{extends "common/layout.jet"}}
{{import "common/menu.jet"}}
{{block Header}}
<!-- this block commes from "common/menu.jet" -->
<nav class="nav">{{yield menu}}</nav>
{{end}}
{{block Content}}
{{.PageHeader}}
{{range .Result}}
<div>

{{end}}
{{end}}Faster than some pre-compiled template engines
Benchmark consist of range over a slice of data printing the values, the benchmark is based on "https://github.com/SlinSo/goTemplateBenchmark",
Jet performs better than all template engines without pre-compilation, and peforms better than gorazor, Ftmpl, Egon which are pre-compiled to go.
