Path attribute for alembic export

Simple example how to create path attribute in Houdini with VEX which represent scene hierarchy for alembic export:

// Perprim wrangle
// Get and define var attrib from primitives
string var_prim_attr = itoa(i@variant); // has to be packed prim
string primnum_attr  = itoa(i@primnum);

// Path builder
string root_dir      = chs("root_dir") + "/";
string item_var_dir  = chs("item_var") + var_prim_attr;
string var_geo_name  = "/" + chs("var_geo_name") + "_" + var_prim_attr + "_geo_" + primnum_attr;
string shape         = "Shape";

string var_path = root_dir + item_var_dir + var_geo_name + var_geo_name + shape;

// Cast @path attribute
s@path = var_path;

Split string by delimiter and get part by index

string path_attr = "/objects/geo1/geo1Shape";
string name = split(path_attr, "/", -1);
