Question

i’m looking for a library that can do the following :

• ask questions and generate an input file
• read that input file
• while reading the modified input file, the lib assigns the value into the program accordingly to the description in the input file.

i wrote a simple program that does it, like this:

>./main
gaussian width:2

here the program cout “gaussian width” and i input “2”. the program also generates parameters.txt file:

gaussian width:2

i can start the program with an existing file:

>./main parameters.txt

it reads the parameter “2” from parameter file and assigns it to int gaussianWidth within the program.

I couldn’t find anything like that on the web, so i’m almost done writing one. but i’mm wondering if there is an elegant library like that, for example in boost.

Answer 1

What you are looking for is program options from boost. However you may need to adapt your input file.
