SYNOPSIS
command | rexi
DESCRIPTION
rexi is an interactive terminal UI for testing regular expressions. It reads input from stdin and lets you evaluate regex patterns in real-time, providing instant visual feedback as matches are highlighted.It supports two evaluation modes:- match: uses Python's `re.match` / `re.search` semantics.- finditer: uses `re.finditer` to iterate all non-overlapping matches.
INSTALL
nix profile install nixpkgs#rexi
CAVEATS
rexi requires input on standard input; it does not accept file arguments directly. Regex syntax follows the Python `re` module rather than PCRE or POSIX.
HISTORY
rexi was created by Roy Reznik (royreznik) and is written in Python using the Textual TUI framework.
