feature: file preview

[Serpentian]

It'd be great, if superfile could preview files, like ranger does. At least text files

[pcause]

This app looks very interesting. If you add preview, how about reusing scope.sh that ranger uses.

Image preview can use similar protocols utilised by Yazi.

A quick update. The text file preview is now complete.
I was actually going to start with the image preview, but it's a bit hard...
So I may need more time, or if anyone has experience writing image previews feel free to contribute!

[pcause]

why not just invoke chafa or viu and pass it dimensions to use.

As far as I know, it's not that simple. :(

I know that both ranger and vifm do image preview with chafa. you could look at their code to see how they do it.

Ctpv is good for that we can use it and it's fast as it's written in C

[AnshumanNeon]

@yorukot can we integrate c or c++ tools for image preview? we can use ueberzugpp, it is a continuation of ueberzug and is in c++ as it's pretty fast. also why are we making a custom file previewer?

[yorukot]

For now, I can definitely accept the use of third-party software, but even so, I still don't know how to do it...

[AnshumanNeon]

@yorukot i have an idea. maybe we can use image previewing as a plugin for superfile. In the plugin we can put ueberzugpp to be a dependency that has to be either manually installed by the user or we will install by ourselves. then the image preview can use ueberzugpp by running the command. like exec.cmd or something like that
