Vayne - Mustache-inspired template compiler and interpreter for D

Vayne has been written mainly for use with vibe.d but it can be used in any other way. It is the successor to jax, a compile-time solution.

Compiles source text/html into bytecode to be interpreted at run time.

Features

• HTML compressor
• Parametrized macros
• Good and detailed error reporting
• Supports user defined escaping and translation

-r --print-preparse print preparser result
-a      --print-ast print ast
-i   --print-instrs print generated instructions
-k   --print-consts print generated constant slots
-b --print-bytecode print generated bytecode and instructions
-t           --time display elapsed time
-v        --verbose verbose output
-c       --compress compress HTML in between template tags
-o     --output-dir output directory
-d  --dep-cache-dir dependant-cache directory
