Remaping attribute values

You might help us if you define what remaping means in your mind.

Hello,

I am trying to remaping existing values to new values within an attribute that is of type enum with a drop down list of:
A
BC
D
E

and would like to updated the values in the list and the actual value assigned to it currently with out losing the data I would like to reasign it to the remap values.

Existing values:
A
BC
D
E

Update(remaping)
A -> A
BC -> D
D -> F
E (deleted)
Thank you,
Jim

Searching for "+modify +enumeration" I found this thread although I recall there are more 'robust' ones for changing enumerations.

Since you will end up with 3 enumerations you will start with a few parellel arrays all of exactly size 3. Lets print two of them vertically:

Index    Old    New[]   Map[]   Comment
0       A       A       0       maps to previous A
1       BC      D       1       maps to previous BC
2       D       F       2       maps to previous D
3       E

You will add your own "values", "colors", and "descriptions" arrays, although perhaps they just have zeros and null strings.

The main key here is the undocumented version of "modify" that accepts the mapping array. Since position 3 is not in your mapping array, old value "E" is lost (which is in old position 3). It doesn't matter that both old and new have value "D" in different positions not mapped to each other.

There is also a Skip list based version which is a lot easier when you are dynamically determining new values and old mappings.

Once you can modify a single module then its just opening them all up, there are other posts for how to get all the modules in a project or folder.

For reasons I don't quite understand you will need to "refresh" all the objects in the module so they display the correct data: for obj in entire mod do{obj.NameAttr = obj.NameAttr}

Yes, there are no 'robust' solutions for changing the type of an attribute, say from "string" to "text"; although there is a tolerable one.

Hello,

Does anyone know the values for the color option?
For the Descs I tried changing "" to an actual string but didn't see it change anyone know why?

Thank you,
Jim
 

int     NewColor[] = {-1, -1, -1} // or figure out real colors; good luck with that
string  NewDescs[] = {"", "", ""}  // or add descriptions for "R - Requirement" etc

Module m = current
if (!null m)
{
    string ErrMess = ""
        m = edit(fullName m, true)
        
        //_Req Eval
        AttrDef ad = find(m, "_Req Eval")
        if(ad != null)
        {
                ErrMess = ""
                string  NewCodes[] = {"R - Requirement", "D - Description", "I - Information Only"}
                int     NewValus[] = {0, 0, 0}  // or perhaps 0,0,0,0
                int     NewColor[] = {-1, -1, -1} // or figure out real colors; good luck with that
                string  NewDescs[] = {"", "", ""}  // or add descriptions for "R - Requirement" etc
                int     NewMapping[] = {0, 1, 2}     // where '-1' is for "R - Requirement" and maps to nothing old
                
                AttrType at = find(m, ad.typeName)
                modify(at, "_Req Eval", NewCodes, NewValus, NewColor, NewDescs, NewMapping, ErrMess)
                if (!null ErrMess) { print "Error(_Req Eval): " ErrMess "\n"}
        }
}
