esprimajs 0.1.0

功能

• ES6支持
• 损坏函数和变量名
• 识别输出
• 模糊字符串

安装

pip install esprima-compiler

示例

示例javascript文件

constAconst=Math.PI,Bconst="Bconst";constCconst="Cconst";functionadd(a,b){functionfoo(){returna+b;}returnfoo();}constDconst="Dconst";functionmul(a,b){returna*b;}constEconst="Econst";letAlet="Alet";constFconst="Fconst",Gconst="Gconst";

重新排列和更改变量：

python -m esprima_compiler -r --mangle-variable test.js

constAconst=Math.PI,Bconst="Bconst",Cconst="Cconst";functionadd($a,$b){functionfoo(){return$a+$b;}returnfoo();}constDconst="Dconst";functionmul($a,$b){return$a*$b;}constEconst="Econst",Fconst="Fconst",Gconst="Gconst";letAlet="Alet";

重新排列变量和损坏变量（包括顶层）以及函数名（顶层除外）：

python -m esprima_compiler -r --mangle-variable-top --mangle-function test.js

const$a=Math.PI,$b="Bconst",$c="Cconst";functionadd($d,$e){function$f(){return$d+$e;}return$f();}const$d="Dconst";functionmul($e,$f){return$e*$f;}const$e="Econst",$f="Fconst",$g="Gconst";let$h="Alet";

重新排列变量、更改变量和函数名（包括顶层），但不标识：

python -m esprima_compiler -i 0 -r --mangle-variable-top --mangle-function-top --mangle-function test.js

const$a=Math.PI,$b="Bconst",$c="Cconst";function$d($e,$f){function$g(){return$e+$f;}return$g();}const$e="Dconst";function$f($g,$h){return$g*$h;}const$g="Econst",$h="Fconst",$i="Gconst";let$j="Alet";

API

编译javascript字符串：
