SimpleTemplateEngine

Struct SimpleTemplateEngine 

Source
pub struct SimpleTemplateEngine { /* private fields */ }
Expand description

简易模板引擎(对齐 PHP think\Template 的基本标签解析)

§支持的标签

标签示例说明
{$var}{$name}变量插值
{$var.attr}{$user.name}嵌套属性(对齐 PHP . 语法,array 模式)
{$var|filter}{$name|upper}过滤器
{$var|default=x}{$name|default='N/A'}默认值
{$var?='x'}三元:真则输出
{$var?:'x'}三元:假则输出 x
{$var??'x'}null 合并
{:func(args)}{:date('Y')}函数调用
{//comment}单行注释
{/*comment*/}块注释
{literal}...{/literal}原文保留

Implementations§

Source§

impl SimpleTemplateEngine

Source

pub fn new(config: ViewConfig) -> SimpleTemplateEngine

创建新引擎

Source

pub fn register_function( &self, name: &str, func: Arc<dyn Fn(&[Value]) -> Result<Value, ViewError> + Sync + Send>, )

注册自定义函数(对齐 PHP Template::extend 扩展机制)

Source

pub fn parse_template_path(&self, template: &str) -> PathBuf

解析模板路径(对齐 PHP parseTemplateFile

PHP 规则:

  1. @ → 跨应用调用 app@template
  2. 首字符 / → 绝对路径
  3. 否则 → view_path/template.view_suffix
