Inspirado en `Gin`.
## Instalación
```bash
go get github.com/zepyrshut/gorender
```
## Uso mínimo
Las plantillas deben tener la siguiente estructura, observa que las páginas a
procesar están dentro de `pages`. Los demás componentes como bases y fragmentos
pueden estar en el directorio raíz o dentro de un directorio.
Puedes cambiar el nombre del directorio `template` y `pages`. Ejemplo en la
siguiente sección.
```
template/
├── pages/
│ └── page.html
├── base.html
└── fragment.html
```
```go
import (
"github.com/zepyrshut/gorender"
)
func main() {
ren := gorender.New()
// ...
td := &gorender.TemplateData{}
ren.Template(w, r, "index.html", td)
// ...
}
```
## Personalización
> Recuerda que si habilitas el caché, no podrás ver los cambios que realices
> durante el desarrollo.
```go
func dummyFunc() string {
return "dummy"
}
func main() {
customFuncs := template.FuncMap{
"dummyFunc": dummyFunc,
}
renderOpts := &gorender.Render{
EnableCache: true,
TemplatesPath: "template/path",
PageTemplatesPath: "template/path/pages",
Functions: customFuncs,
}
ren := gorender.New(gorender.WithRenderOptions(renderOpts))
// ...
td := &gorender.TemplateData{}
ren.Template(w, r, "index.html", td)
// ...
}
```

## Descargo de responsabilidad
Esta librería fue creada para usar las plantillas en mis proyectos privados, es
posible que también solucione tu problema. Sin embargo, no ofrezco ninguna
garantía de que funcione para todos los casos de uso, tenga el máximo
rendimiento o esté libre de errores.
Si decides integrarla en tu proyecto, te recomiendo que la pruebes para
asegurarte de que cumple con tus expectativas y requisitos.
Si encuentras problemas o tienes sugerencias de mejora, puedes colocar tus
aportaciones a través de _issues_ o _pull requests_ en el repositorio. Estaré
encantado de ayudarte.
