# rrf

`rrf` stands for Realtime Regexp Filter.

It's a small utility for realtime filtering of text streams in your terminal

using regular expressions.

![Demo](./rrf-demo.mov)

## Usage

```

rrf --help

Usage:

  rrf [OPTIONS]

  rrf will read from stdin. Usually you'll want to do something like

  `tail -f my.log | rrf`

  Once running, type a regex. Once a valid regex is entered, the output filter

  will be updated.

Application Options:

      --posix           Use POSIX ERE (egrep) syntax

      --filtered-count  Show count of filtered lines between output

      --no-highlight    Do not highlight matches in output

Help Options:

  -h, --help            Show this help message

```

## Future plans

- Highlighting customization?

- Find something that will give me readline in the input prompt?

   Nothing I've found so far allows stateful reuse. They all block until a line

   is read, and I want to be able to keep streaming stdin while editing.
