pvw

 

Live preview for command-line tools.

pvw makes it easy to tweak shell incantations by showing an interactive preview on every key stroke.

Features

• Show live preview of command-line output as you type
• Supports programs with interactive text interfaces, such as vim and top.

That's it! See As Compared to X for more featureful alternatives and Roadmap for where pvw is heading.

Installation

Pre-built packages are not available yet.

Installing from source is pretty easy if you have Cargo setup:

$ git clone https://github.com/sullvn/pvw.git
$ cargo install --path pvw

As Compared to X

Pvw is pretty early along, so you will probably be better served by one of these:

• interactively creates a live preview for a shell command with placeholder. Requires Bash and fzf. pvw does not have any placeholder substition features.
• up creates a live preview for the command at the end of a shell pipe. pvw does not include this functionality yet.

Roadmap

1. Fix outstanding bugs
2. Publish pre-built binaries and packages
3. Create test framework
4. Support shell features in commands
5. Allow using pvw as part of a shell pipe
6. Integrate cowbox for Just Run It ^™️ capabilities
