Modifying a node's identifier with the . and = operator breaks the tree #200
Description
making use of the . and = in order to modify a node's identifier causes the node to disappear
Ex:
tree["old_identifier"].identifier = "new_identifier "
the code I used to reproduce the issue:
from treelib import Node, Tree
def create_tree():
tree = Tree()
tree.create_node("root" , "root")
for i in range(2):
id = str(i*100)
tree.create_node(id, id , parent = "root")
for j in range(1, 3):
id = str(i) + str(j*10)
tree.create_node(id, id , parent = str(i *100))
for k in range(1, 3):
id = str(i) + str(j) + str(k)
tree.create_node(id, id , parent = str(i) + str(j*10))
tree.show()
return tree
def break_tree(tree):
tree["020"].identifier = "030"
tree.show()
tree = create_tree()
break_tree(tree)
this outputs:
root
├── 0
│ ├── 010
│ │ ├── 011
│ │ └── 012
│ └── 020
│ ├── 021
│ └── 022
└── 100
├── 110
│ ├── 111
│ └── 112
└── 120
├── 121
└── 122
Tree is empty
root
├── 0
│ ├── 010
│ │ ├── 011
│ │ └── 012
if you don’t mind I can work on this and please let me know if you have any feedback
