Lightweight embedded scripting language
## Brief introduction
**fakejava** 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.
[fake for C/C++](https://github.com/esrrhs/fake)
[fake for Go](https://github.com/esrrhs/fakego)
## Script feature
* 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
## Sample
```
-- Current package name
package mypackage.test
-- include file
include "common.fk"
-- struct define
struct teststruct
sample_a
sample_b
sample_c
end
-- const define
const hellostring = "hello"
const helloint = 1234
const hellomap = {1 : "a" 2 : "b" 3 : [1 2 3]}
-- func1 comment
func myfunc1(arg1, arg2)
-- Java static function calls and Java class member functions
arg3 := cfunc1(helloint) + arg2:memfunc1(arg1)
-- Branch
if arg1 < arg2 then
-- create routine
fake myfunc2(arg1, arg2)
elseif arg1 == arg2 then
print("elseif")
else
print("else")
end
-- for loop
for var i = 0, i < arg2, i++ then
print("i = ", i)
end
-- array use
var a = array()
a[1] = 3
-- map use
var b = map()
b[a] = 1
b[1] = a
-- Int64
var uid = 1241515236123614u
log("uid = ", uid)
-- sub func call
var ret1, var ret2 = myfunc2()
-- other package call
ret1 = otherpackage.test.myfunc1(arg1, arg2)
-- struct use
var tt = teststruct()
tt->sample_a = 1
tt->sample_b = teststruct()
tt->sample_b->sample_a = 10
-- switch branch
switch arg1
case 1 then
print("1")
case "a" then
print("a")
default
print("default")
end
-- multi return value
return arg1, arg3
end
```
## Java Sample
```
// create instance
fake f = fk.newfake(null);
// regist all func marked with @fakescript in package
fk.reg(f, "com.test");
// parse script file
fk.parse(f, "test.fk");
// run script func myfunc1, put in two param 1 and 2
double ret = (double)fk.run(f, "myfunc1", 1, 2);
```
## How to use
