play

README

play

play is a TUI playground for your favorite programs, such as grep, sed and awk.

Demo

It uses the excellent tview library for the UI.

Installation

$ git clone https://github.com/paololazzari/play
$ cd play
$ go build -o /usr/local/bin/

Usage

./play <program>

N.B. The program must be installed on your machine.

The input is evaluated immediately as you type without any validation. If you want to use play in read-only mode, thus avoding any file changes (such as those that would result if, for instance, sed -i was used), then you can use a docker container:

$ docker run --rm -it -v "$(pwd)":/play:ro plazzari/play:latest <program>

To exit the application, use Ctrl+C.

To exit the application printing the input expression to stdout, use Ctrl+S.
