have much groups(maybe group1,group2 to group100),and i want to select prims not in group to other group,

if use group combine,i have to type group1,group2,…. to group100,It's like a joke.

so wirte vex in attribwrangle

————————————————————-
string mygroup = detailintrinsic(0, “primitivegroups”);

int sss = len(mygroup);

for(int i=0;i<sss;i++)
{if (!inprimgroup(0,mygroup,@primnum))

{setprimgroup(0, “ss”, @primnum, 1);}
}
————————————————————-
it works,but houdini have other easy way to do it?

to group everything that is not in group yet you can create Group SOP and in the Base Group type:!?*

this can be very inefficient, if your groups don't need to overlap consider using attributes instead

and,i find a bug in attribuewrangle:

string magroup = detailintrinsic(0, “primitivegroups”);
int sss = len(magroup);
setprimgroup(0, “ss”, @primnum, 1);

for(int i=0;i<sss;i++)
{if (inprimgroup(0,magroup,@primnum))
{setprimgroup(0, “ss”, @primnum, 0);}
};

it work well,and make not in group prim to a group named ss
but if you add a line:
string magroup = detailintrinsic(0, “primitivegroups”);
int sss = len(magroup);
setprimgroup(0, “ss”, @primnum, 1);

for(int i=0;i<sss;i++)
{if (inprimgroup(0,magroup,@primnum))
{setprimgroup(0, “ss”, @primnum, 0);}
};
@group_ss=0;

show the group ss in spreadsheet,it not bo zero

but if you add a prim attribuewrangle
cut @group_ss=0; to this

now show the group ss in spreadsheet,it be zero,correct

so i think have a bug between setprimgroup and @group_name

should work in any place that accepts group patterns

so i think have a bug between setprimgroup and @group_name
it's not a bug, but how VEX executes functions that are able to write to noncurrent element like setprimgroup() or setpointattrib(), …
they are queueued at the end and executed as a single threaded process as multiple ones can write to the ame element, that's why they win over your s@group_ss = 0 that is seemingly supposed to execute afterwards
while it's not thechnically a bug it's definitely not intuitive and requires some acceptance of how it works

use code block, not only you can use special characters in there it's also much cleaner and safer way to share code as it's copy/paste friendly
like this:
string magroup[] = detailintrinsic(0, “primitivegroups”);
