Vlad is a lightweight header-only library for fuzzy string search. It includes an implementation of efficient generic levenshtein automata and a generic trie for indexing documents and counting unique words.

There are two demo programs. lgrep is like a basic grep with fuzzy matching. query indexes a text file by line and also does fuzzy search.

Prerequisites

You'll need boost, cmake and a recent clang++. Also, doxygen, if you want HTML documentation.

Getting started

  1. Create a build directory next to src.
  2. Run cmake .. in the build directory.
  3. Run make all test.
  4. Run make doc if you want an HTML version of the documentation.
  5. Take a look at lgrep and query.
