Character String Operations and Interpolation, Magic Edition

Performs complex string operations compactly and efficiently. Supports string interpolation jointly with over 50 string operations. Also enhances regular string functions (like grep() and co). See an introduction at < https://lrberge.github.io/stringmagic/>.

Encrypt and Decrypt Strings, R Objects and Files

A consistent interface to encrypt and decrypt strings, R objects and files using symmetric and asymmetric key encryption.

Parse 'YMD' Format Number or String to Date

Convert 'YMD' format number or string to Date efficiently, using Rust's standard library. It also provides helper functions to handle Date, e.g., quick finding the beginning or end of the given period, adding months to Date, etc.

Manipulation of JSON Strings

Fast manipulation of JSON strings. Allows to extract or delete an element in a JSON string, merge two JSON strings, and more.

Fast String Searching

Wrapper for the Succinct Data Structure C++ library (SDSL v3) < https://github.com/xxsds/sdsl-lite> enabling fast string searching using FM indices. Partial string matching can be ~50-fold faster than simple string scans for many real-world string collections (corpora). A given corpus is converted into a compact in-memory FM index representation that can be efficiently queried for partial string matches.

Dynamic String Formatting

Pass named and unnamed character vectors into specified positions in strings. This represents an attempt to replicate some of python's string formatting.

Fuzzy String Comparison

Provides string similarity calculations inspired by the Python 'thefuzz' package. Compare strings by edit distance, similarity ratio, best matching substring, ordered token matching and set-based token matching. A range of edit distance measures are available thanks to the 'stringdist' package.

Readable String Abbreviation

Strings are abbreviated to at least "minlength" characters, such that they remain unique (if they were). The abbreviations should be recognisable.

Encrypts and Decrypts Strings

Encrypts and decrypts strings using either the Caesar cipher or a pseudorandom number generation (using set.seed()) method.

Interpreted String Literals

An implementation of interpreted string literals. Based on the 'glue' package by Hester & Bryan (2024) but with a focus on efficiency and simplicity at a cost of flexibility.
