Hi,
No, I had no idea that Sean was bringing an LSU student to work on this.
I have a sophomore CS student starting right now. The idea is to implement
PetscOptionsInsertJSONFile(MPI_Comm comm,const char file[],const char
section[],PetscBool require)
where every child of section would be parsed an inserted.
i.e. parsing the following json file with section="petsc"
{
"version": "1.0",
"encoding": "UTF-8",
"mystuff": {
"key1": "val1",
"key2": [ "a", "b", "c"]
},
"petsc": {
"sub1": {
"key1": "val1",
"key2": [ "a", "b", "c"]
},
"sub2": {
"key1": "val1",
"key2": [ "a", "b", "c"]
},
}
would have exactly the same result as using
-sub1_key1 val1 -sub1_key2 a,b,c -sub2_key1 val1 -sub2_key2 a,b,c
on the command line.
My goal is to be able to use a single json file to control an entire
computation (mesh generation, preprocessing, analysis, postprocessing,
visualization). It seems to me that this is implementable with minor incursions
into the petsc code base.
