Have you tested running on master?

[tanrax]

Yes. Same results

I think I may have some extra information that might help here. I thought it didn't work for me but turns out it does... but only for images smaller than around 42k. Anything bigger than that doesn't get a preview.
See the attached screenshots:

Now an image bigger than 42k:

I was able to reproduce this consistently.

[tanrax]

I can not see it.

How can I give you more information? Thank you

[Wes974]

I found a way to make it work.
Copy the folder ~/.config/ranger/ somewhere on your computer (your Desktop for example) then remove everything in ~/.config/ranger/.

Open iTerm and run this command :

ranger --copy-config=all

Once this is done, open your ~/.config/ranger/rc.conf file to edit those line

set preview_images true
set preview_images_method iterm2

Let me know if it worked for you.

[tanrax]

It does not work for me. What version of python do you use?

[Wes974]

I use python 2.7.13. If you can try to use this version to see if it changes something.

[tanrax]

I followed your steps, with both the brew version and the master version with no results. :(

[Wes974]

All right we can try another thing, in your rc.conf, find this line :

set draw_borders false

Set it to true and relaunch ranger. See if it changes something.

[Wes974]

Hey are you running ranger inside of tmux by any chance ?

[tanrax]

I try everything in and out of Tmux.

[Wes974]

Well then I don't know what to do, sorry

[looneym]

Howdy. I'm using ranger in tmux and the image preview doesn't work. Works outside of tmux but I sure would like it if it worked inside of it. I followed the steps mentioned here but no luck #864 (comment)

If anyone has any ideas as to why tmux might break this please let me know!

[toonn]

@looneym tmux is a lot more limited than regular terminals in what it can do I don't think it supports any of the previewing methods.
@tanrax Do you still have this issue?

[tanrax]

@toonn I didn't get it to work... the problem persists.

[toonn]

Could you remove your scope.sh and comment out the line set preview_script ~/.config/ranger in rc.conf? Don't try in tmux it won't work. Also make sure you're running the latest version of ranger 1.9.1.

[tanrax]

@toonn I don't have any scope.sh
rc.conf

[tanrax]

ohh!

[toonn]

Did you comment out or remove the set preview_script line? And try running ranger with the --debug flag, might give us some more info.

[BenBergman]

I have image previews working for me in iterm2 both in and out of tmux, but if I am inside tmux I can only preview images that are under ~85k. Is there any setting I can add to make it work better in tmux?

[toonn]

Not that I know of sadly.

[jsatk]

I'm in the exact same boat as @tanrax. I just tried everything listed in here. Nothing works. I just get prompted to "open with". @Wes974's comment here installed a bunch of new stuff I didn't have in ~/.config/ranger, but it didn't fix my problem.

[jsatk]

@BenBergman any chance you could share what your config looks like? I'm in tmux + iTerm as well.

[jsatk]

@toonn This is the entirety of my ~/.config/ranger.rc.conf.

# https://github.com/ranger/ranger/wiki/Image-Previews#with-iterm2
set preview_images true
set preview_images_method iterm2

And my ~/.config/ranger/rifle.conf is the exact default one with this single line added.

mime ^image, flag f = open -- "$@" # Open images in Preview.app on macOS.

[jsatk]

Update — the above does work in iTerm 2. It just doesn't work in tmux + iTerm 2. As said a few times in this issue, it's anticipated that image preview won't work in tmux. If anyone knows how to get it to work I'm all ears, but as far as I'm concerned this issue is resolved for me since it is working in iTerm 2 and has been explicitly stated that it won't work in tmux.

[BenBergman]

@jsatk Here is my ~/.config/ranger/rc.conf: https://gist.github.com/BenBergman/f95a558c3f73c90222639dc4f215f448

That file was either auto generated or I stole it from somewhere as I don't recall ever editing it before, at least not all of those lines.

I also tossed in my .tmux.conf in case there is anything helpful in there. That one is more handcrafted by me.

In case it is relevant, I also use zsh instead of bash.

[toonn]

I'm closing this in the hope that #1601 fixed it.

[hawkinchina]

I meet the same problem. it works outside of tmux, but inside tmux, it cannot work. this issue has already fixed, or not ?

[toonn]

Yes, but I doubt you're running 1.9.3 already?

[hawkinchina]

my ranger‘s version： 1.9.3

➜ /Users/jack >ranger --version
ranger version: ranger 1.9.3
Python version: 3.7.5 (default, Nov 1 2019, 02:16:38) [Clang 10.0.0 (clang-1000.11.45.5)]
Locale: zh_CN.UTF-8

[toonn]

Then you're probably trying to preview "large" images. Tmux prevents images larger than a couple kB from being shown. Nothing we can do about that.

Thank @Wes974. It works perfectly. However, it asked me permission to allow download of files by iterm2. Does this method download images somewhere?

[toonn]

Maybe iTerm2 doesn't include the imgcat functionality necessary for the previews but is able to download it automatically? No idea though, never heard of this.
