#fakescript
Lightweight embedded scripting language
Brief introduction 中文
fakescript is a lightweight embedded scripting language , using Java language, grammar lessons from lua, golang, erlang, based on jflex, bison generative grammar tree , compiled into byte code interpreted. fakescript for C/C++
- The syntax is similar to lua
- All function
- Support array, map, unlimited nested
- Support generating routine like fake testfunc (param1), to achieve the effect of multithreading
- Support binding Java Static functions and Java class member functions
- With interpreter
- Support multi return value
- Support profile, can get the script running time of each function
- Support hot update
- Support Int64
- Support const definitions
- Support Package
- Support struct
- Support byte code optimize
- Support global map
