Introduction
In this tutorial we learn how to install triehash on Ubuntu.
What is triehash
triehash is:
TrieHash generates perfect hash functions as C code which then gets compiled into optimal machine code as part of the usual program compilation.
TrieHash works by translating a list of strings to a trie, and then converting the trie to a set of recursive switch statements; first switching by length, and then switching by bytes.
TrieHash has various optimizations such as processing multiple bytes at once (on GNU C), and shortcuts for reducing the complexity of case-insensitive matching (ASCII only). Generated code performs substantially faster than gperf, but is larger.
TrieHash was written for use in APT.
There are three methods to install triehash on Ubuntu. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
