previuwu

An all-in-one preview window for the furries.

Uses egui to render the preview window.

STATUS: Proof of Concept (⚠️ heavy work in progress).

Demo

Preview texts

previuwu.mp4

Preview images

previuwu.mp4

Install

Better don't install it as of now, unless you want to contribute.

cargo install --git https://github.com/sayanarijit/previuwu

Usage

Preview a single file:

previuwu /path/to/file

Allow streaming input from stdin:

previuwu /path/to/file --pipe -

Also allow streaming input from a named pipe:

# mkfifo path/to/input.fifo
previuwu /path/to/file --pipe - --pipe path/to/input.fifo

Use Case

Run a slide show of the contents in your $PWD:

ls -1 | while read -r file; do echo "$file"; sleep 1; done | previuwu -p -

Example usage with xplr and nnn:

# Create a fifo file
mkfifo /tmp/previuwu.fifo

# Run previuwu in background (will close automatically when done)
previuwu --pipe /tmp/previuwu.fifo &

# Run xplr with fifo enabled
xplr --on-load 'StartFifo: /tmp/previuwu.fifo'

# Run nnn with fifo enabled
NNN_FIFO=/tmp/previuwu.fifo nnn

Supports

I plan to support as many input types as possible.

• Stdin
• Named Pipes (fifo)
• Socket
• ...ideas?

Very basic (ugly) support for the following file types has been implemented:

• Directory
• Text
• Images
• ...contribute?

Contribute

First of all, thank you.

Please go through src/preview and try to implement loading and/or rendering as many file types as you can.

Loading is the easy part. Rendering might require some experience with egui.

Some files can be really slow to load/render in development mode (cargo run). Try running in release mode (cargo run --release).
