val parser = ExpressionParser()
val result = parser.evaluate("sin(PI)+1+cos(PI)")
println(result)
// result 0.0
C/C++
build the project with ./gradlew build
Navigate to KParser/build/bin/linux/releaseShared/
Use the generated libkparser_api.h (header file) and libkparser.so (shared object file)
#include <iostream>
#include "libkparser_api.h"
int main() {
libkparser_ExportedSymbols* lib = libkparser_symbols();
libkparser_kref_io_thelimitbreaker_ExpressionParser kparser = libkparser_kref_io_thelimitbreaker_ExpressionParser();
double result = lib->kotlin.root.io.thelimitbreaker.ExpressionParser.evaluate(kparser,"1+sin(PI)+cos(PI)",3);
std::cout<<result << std::endl;
return 0;
}
Compiling C/C++ (Command Line)
g++ main.cpp libkparser.so
Compiling C/C++ (CMake config)
Provided libkparser_api.h and libkparser.so are under folder kparser
