Rename names numbers

[joiec...@gmail.com]

Hi there,

I need to remove all numbers from objects names coming from CAD data because they are WAY too long.

I was trying the method described here: https://www.reddit.com/r/Maya/comments/cwpm8z/pro_tip_modifysearch_and_replace_names_supports/

But I can't make it work.

In a name like "building012056floor261861carpet096321" If I search for something like ([0-9]+), y remove the first numbers, but if there is any letter and then another number, that second number doesn't get removed.

Any tips?

If you don't care a ton about naming other than length, you can try this MEL. Just select all the objects and run it, and it clips to the first 3 letters of the object, appending a number for duplicates. I added comments for clarity:

//create array from selected
string $objs[] = `ls -sl`;
//for each...
for ($node in $objs)
{
//create a string that is using the first 3 letters of the name in this example
string $shortName = `substring $node 0 3`;
//rename the nodes based on the first 3 letters. If you want more, just up the integer. When there are resulting objects with the same name, a number is added to the end
rename $node $shortName; 
}

Thanks, but that's not exactly what I need.

The model comes from CAD data via FBX. The CAD software used apparently allows MAYA's illegal characters in names, such as tildes, commas or similar. So when exported, FBX convert those symbols to numbers somehow. But the names are important because are related to the material they need to have.

That's why I need to remove only the numbers and put a "_" symbol instead or something like that.

Cheers.

Found a snippet I was able to modify that I think basically does what you want. Just select the objects and run:

string $objs[] = `ls -sl`;

for ($node in $objs)
{
string $myString = $node;
  while(`match "[0-9]+" $myString` != ""){
 $myString = `substitute "[0-9]+"  $myString "_"`;
  }
  rename $node $myString;
}

There is a pattern renamer in bonus tools under the window sub menu.
Here is a tutorial video from Roland Reyer how to use it.

Maybe worth a try.

There are a couple ways to tackle this. 
I'd look at some simple looping to do it

object =  "building012056floor261861carpet096321"
#using re.sub
import re
newname  = re.sub(r'\d+', '', object)
print(newname)


#using 
import re.sub but replacing the # with "_"
numbers = r"[0-9]"
newname  = re.sub(numbers, '_', object)
print(newname)

#using the built in function of join (and a loop)
new_name = "".join((z for z in object if not z.isdigit()))
print(new_name)

#using a loop 

# but this one will replace the numbers with "_"
new_name = ""
for n in object:
    if n.isdigit():
        b = "_"
    else:
        b = n
    new_name += b

print(new_name)

or... ( and probably what you are looking for ) 

#using if elif else

# replace a string of numbers with just one underscore by checking... -1
object =  "building012056floor261861carpet096321"
new_name = ""
for i,n in enumerate(object):
    #print("i:{}, n:{}".format(i,n))
    try:
        if object[i-1].isalpha() and n.isdigit():  
            new_name += "_"
        elif object[i-1].isdigit() and n.isdigit():
            pass
        else:
            new_name += n
    except:
        pass

print(new_name)

Not sure if anyone tried it, but the Mel I posted last night does work too :)

string $objs[] = `ls -sl`;

for ($node in $objs)
{
string $myString = $node;
  while(`match "[0-9]+" $myString` != ""){
 $myString = `substitute "[0-9]+"  $myString "_"`;
  }
  rename $node $myString;
}

Thanks Anthony for the code. We keep it as it will surely be useful someday. 

Nice day
