stringi (pronounced “stringy”, IPA [strinɡi])is THER package for string/text/natural language processing.It is very fast, consistent, convenient, and — thanks to theICU – International Components for Unicodelibrary — portable across all locales and platforms.

Available features include:

• string concatenation, padding, wrapping,
• substring extraction,
• pattern searching (e.g., with Java-like regular expressions),
• collation and sorting,
• random string generation,
• case mapping and folding,
• string transliteration,
• Unicode normalisation,
• date-time formatting and parsing,

and many more.

Package Maintainer:Marek Gagolewski

Authors and Contributors:Marek Gagolewski,with contributions from Bartłomiej Tartanus and many others.

The package's API was inspired by that of the early (pre-tidyverse; v0.6.2)version of Hadley Wickham'sstringrpackage (and since the 2015 v1.0.0stringr is powered bystringi).
