I have a problem related to passing arguments to a C++ compiled executable. The program emulate the behaviour of a particular inference engine: the setup of the engine is load at runtime from an XML file, and then I want to call it from command line with different input values.
The characteristic of the input are:
- Every time that I call the program, the input structure is different, because the system itself is different.
- The input is a set of couple {name, value}, one for each part of the system.
- I have to separate the configuration XML from the input.
- I call the program from a PHP or Node.js server, since it return a result that I expose to the outside through an API.
- Input value are obtained from an HTTP post request.
By now I have tried these solutions:
- Pass it from the command line ex: "./mysoftware input1 value1 input2 value2 ...etc". A little unconfortable, since I have up to 200 input.
- Create a file with all the couples name,value and then call the program that parse the file and then destroy at the end. This is a bottleneck of performance for my API, because at every call I have to create and destruct a file.
Does anyone know a better way to approach this problem?
