previuwu

A generic previewer that can preview anything as everything.

Uses egui to render the preview window.

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

Install

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

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

Usage

Preview a single file:

bash previuwu /path/to/file

Allow streaming input from stdin:

bash previuwu /path/to/file --pipe -

Also allow streaming input from a named pipe[1]:

```bash

mkfifo path/to/input.fifo

previuwu /path/to/file --pipe - --pipe path/to/input.fifo ```

Use Case

Example usage with xplr:

```bash

Create a fifo file

mkfifo /tmp/xplr.fifo

Run previuwu in background (will close automatically when done)

previuwu --pipe /tmp/xplr.fifo &

Run xplr with fifo enabled

xplr --on-load 'StartFifo: /tmp/xplr.fifo' ```

Supports

I plan to support as many input types as possible.

• [x] Stdin
• [x] Named Pipes (fifo)
• [ ] Socket
• ...ideas?

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

• [x] Directory
• [x] Text
• [x] Images
• ...contribute?

Contribute

First of all, thank you.

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

Parsing 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).
