Aspect is a compiling template engine for Lua and LuaJIT. |
Aspect is a compiling templating engine for Lua and OpenResty.
The key-features are...
- Well known: The most popular syntax is used - Twig compatible, Jinja/Liquid like.
- Fast: Aspect compiles templates down to plain optimized Lua code. Moreover, Lua code compiles into bytecode - the fastest representation of a template.
- Secure: Aspect has a sandbox mode to evaluate all template code. This allows Aspect to be used as a template language for applications where users may modify the template design.
- Flexible: Aspect is powered by a flexible lexer and parser. This allows the developer to define their own custom tags, filters, functions and operators, and to create their own DSL.
- Supports lua 5.1/5.2/5.3 and luajit 2.0/2.1 (with OpenResty)
- Has console renderer.
- No dependencies. Pure Lua.
