rulex CLI

⚠️ DEPRECATED ⚠️ Use the pomsky-bin crate instead. Rulex was renamed to pomsky.

This CLI allows you to compile rulex expressions to regexes in the command line.

Use pre-built binaries

Binaries are available for Windows, Linux and macOS. Download them from the releases page.

Install from source

This requires that a recent Rust toolchain is installed. Instructions for how to install Rust can be found here.

Install the CLI with

cargo install rulex-bin

Usage

Then you can compile rulex expressions to a regex flavor of your choice; the default is PCRE.
