fix: remove wrong namespace Signed-off-by: stonex <1479765922@qq.com>
Provides support for evaluating arbitrary C-like artithmetic/string expressions like govaluate.
"1 + 1 == 2"."a + 1 == 2"."a.b == 1"."foo(a, b)".[x] Parse expression and get tokens.
[ ] Build expression tree by tokens.
[ ] Support basic math expression.
[ ] Support variable and accessors.
Eval(params), params is a map like name: object in gvaluate .params is int ,float, string.params should reload operator[] and operator for access and compare. Maybe we can accomplish it by define a base object or use template to support accessors.[ ] Add benchmark for Cvaluate.
