suffix_trees
============

|ci| |codecov|

Python implementation of Suffix Trees and Generalized Suffix Trees. Also
provided methods with typcal applications of STrees and GSTrees.

Installation
~~~~~~~~~~~~

.. code:: bash

   pip install suffix-trees

Usage
~~~~~

.. code:: python

   from suffix_trees import STree

   # Suffix-Tree example.
   st = STree.STree("abcdefghab")
   print(st.find("abc")) # 0
   print(st.find_all("ab")) # [0, 8]

   # Generalized Suffix-Tree example.
   a = ["xxxabcxxx", "adsaabc", "ytysabcrew", "qqqabcqw", "aaabc"]
   st = STree.STree(a)
   print(st.lcs()) # "abc"

What are high entropy strings?

High entropy strings

Contains unicode homoglyphs which can be used in supply chain confusion attacks.

What are unicode homoglyphs?

Unicode homoglyphs

Contains a dependency which resolves to a remote HTTP URL which could be used to inject untrusted code and reduce overall package reliability.

What are http dependencies?

HTTP dependency
