TNSP-bridge is a tool used to facilitate the conversion of tensor data from the format of [the old TNSP](https://www.sciencedirect.com/science/article/pii/S001046551830078X) to [TAT](https://github.com/USTC-TNS/TNSP/tree/main/PyTAT) format.
It's important to note that different versions of TNSP may have variations in their data structures,
but this specific subproject focuses on compatibility with TNSP version 4.
And we support the conversion of non-symmetry tensors and boson/fermion \(Z(2)\) / \(U(1)\) symmetry tensors of various scalar types.
# Install
Please either copy or create a soft link for the directory in the `site-packages` directory.
Alternatively, users can utilize pip to install the TNSP-bridge package by running the command `pip install tnsp_bridge`.
# Documents
The only function is `bridge`, which accepts a function that extracts the old version tensor data line by line and returns the tensor in the new version.
For example, here is the old version of the data:

The code below converts the aforementioned data,
stored in the string variable named `example_data`, to the new version format:
from bridge import bridge
data_line_by_line = example_data.split("\n")
data_line_by_line.reverse()
print(bridge(data_line_by_line.pop, compat=True, parity=False))
{names:[A1_1.n,A1_1.R,A1_1.D],edges:[{arrow:0,segment:{0:1}},{arrow:1,segment:{-1:1,-2:2,-3:2,-4:1}},{arrow:1,segment:{1:3,2:2,3:1}}],blocks:{[0,-1,1]:[0.234469,0.130024,-0.0318424],[0,-2,2]:[0.453563,-0.0140878,-0.0903963,-0.0207322],[0,-3,3]:[-0.352353,-0.0124568]}}
The function `bridge` has two optional arguments.
The first one is `parity`, used to distinguish the symmetry group of a symmetry tensor.
When `parity` is set to `False` (default), it should be a fermion or boson \(U(1)\) symmetry tensor.
If set to `True`, a fermion or boson \(Z(1)\) symmetry tensor is considered.
The second argument is `compat`, which distinguishes the version in the old TNSP.
Within old TNSP, there are two data formats: the older one is processed when `compat` is set to `True`, and the newer one if set to `False` (default).
