Like "ls", but for images. Shows thumbnails in terminal using sixel graphics.

lsix's Issues

No output on xfce4-terminal

There is no output at all when I try to use lsix. This was tested with bash and sh (pictured), on xfce4-terminal 0.8.7.4 on arch linux. There is no output with xterm either.

Xterm Nothing Appears

Using Gentoo Linux. installed lsix by placing in file: /tmp/lsix.

I'm in a Gnome desktop. I installed xterm

`jlpoole@taurus ~/Pictures $ eix -I xterm
[I] x11-terms/xterm
Available versions: 327{tbz2} ~333 ~337 {Xaw3d +openpty toolbar truetype unicode xinerama}

Homepage: https://invisible-island.net/xterm/
Description: Terminal Emulator for X Windows

jlpoole@taurus ~/Pictures $
`

I then launch an xterm:

xterm -ti vt340 &

And then within the displayed Xterm:

My /home/jlpoole/.Xresources file:

 #
 # per    
 #  https://github.com/hackerb9/lsix/blob/master/lsix
 #
 #   xterm -ti vt340

Create a github release.

First of all: thanks for lsix! It's really great.

For packaging and releasing lsix -- e.g. with package managers (like pacman and apt-get) -- a release is a must, sources can not be pulled from master, as the packagers have no control over how the master branch changes.

Luckily GitHub has their release system, for how to create releases see instructions here

Thanks, and have a great day!

Problems with st-sixel

Hi

I'm using st-sixel (https://github.com/galatolofederico/st-sixel) which lsix doesn't realise has sixel capabilities. I got lsix working on it by brute force (setting hassixel=yup) but I don't the clever (correct) way to do this.

Hope you're able to help

ERROR: montage: delegate library support not built-in

On certain files, running lsix will still display the image but with an error message:

montage: delegate library support not built-in 'glasses.png' (XML) @ warning/profile.c/ValidateXMPProfile/1945.

How can I get rid of this error message, or at least suppress it?

-sh: /usr/local/bin/lsix: Permission denied

Hi, I put the file in /usr/local/bin, and it show the error that permission denied. I used this in Mac.

xterm not being recognised as sixel supported.

Using xterm on NetBSD 9.0_STABLE. I've set .Xresources to read XTerm*decTerminalID: vt340
lsix was placed in /usr/bin as there is no /usr/local on this system. ImageMagick is also installed.

xterm recognized the script and outputs the error Error: Your terminal does not report having sixel graphics support

Supposedly it should detect bg colour, but this is what I get:

Here's my .Xresources.

Neovim Terminal with hologram.nvim

Hi,

First of all, I'm aware there already was a (now closed) issue about vim support previously, I am relatively new to github, so I was unsure if I should comment on the closed issue or open a new one.

Closed issue: issues/21

Neovim currently has some plugins which allow images to be displayed, like hologram.nvim.

hologram.nvim mentions potential support for sixel graphics down the road.

Does the existence of such plugins make it possible for lsix to work inside neovims terminal in the future?

Can't detect sixel support in yaft

yaft is a framebuffer terminal with sixel support: https://github.com/uobikiemukot/yaft

"convert foo.jpg -geometry 800x480 sixel:-" does work in yaft.

But lsix says "Error: Your terminal does not report having sixel graphics support."

Your terminal does not report having sixel graphics support

Hello,

I have a problem since formatting my PC, lsix no longer works whereas before, it worked fine (with the Guake terminal)

I have this message displayed:

Error: Your terminal does not report having sixel graphics support.

Please use a sixel capable terminal, such as xterm -ti vt340, or
ask your terminal manufacturer to add sixel support.

You may test your terminal by viewing a single image, like so:

convert  foo.jpg  -geometry 800x480  sixel:-

If your terminal actually does support sixel, please file a bug
report at http://github.com/hackerb9/lsix/issues

Please mention device attribute codes: ^[[?65;1;9c

I did the test with xtem, the images are displayed. For convert, in guake, no return. In xterm my image is displayed.

thank you for helping me

Native Wayland support?

Hi! this looks great but I'm running native Wayland using Sway. Do you have any plans to support Wayland? If I wanted to implement that myself, where would I look?

Get this to work on MacOS

When i run this i get an error saying that the commands mapfile , montage , convert .

hope it is possible to fix this

Check for other animated formats

There is a check for gif images to only draw the first frame if no filename is given. Other animated formats such as webp fall through the cracks.

Regression from #55: Alacritty-sixel error "mention attribute codes: ^[[?6c"

Regression from #55

The attribute code seems to have changed for alacritty-sixel from #55's ^[[?4;6c to simply ^[[?6c or I might be doing something funny..

Flag to remove image labels

Currently lsix displays labels if I don't want to. Would be nice to add a flag like --no-labels to remove them so I'll see images only

Support OSC 8 (hyperlinks) to make previews clickable

Hi,

I really like your little tool, and I'm surprised that a shell script is sufficient for that (with help of ImageMagick).

I'd like you to consider adding hyperlink (OSC 8) support so the generated previews are clickable. This would be a great addition, what do you think?

Filenames with spaces

The script doesn't deal well with filenames that have spaces in them.

eg, I have a file named Bitbucket errors.png in the current directory...

$ lsix *.png
montage: unable to open image 'Bitbucket': No such file or directory @ error/blob.c/OpenBlob/3537.

mlterm display nothing except for a new file output named sixel:-

i use mlterm with versoin 3.9.0 as my VT on Centos 6.5， then i run ./lsix demo.jpg as well as i tested some other different kind of images like PNG or JPEG, then the terminal display nothing，except for a new file output named sixel:-, so what happened? tks a lot.

BTW: X Server was installed on my windows7 system, and i try the command display demo.jpg, it works very well.

Support for Alacritty

Alacritty is getting support soon it seems, and there is already work available for installation.
For example https://github.com/microo8/alacritty-sixel

I tested it out and the convert example works as expected. lsix however still displays an error.

Attribute code in error message: ^[[?4;6c.

macOS support with brew install?

Suggestion: Check for dependencies and alert user to install them.

I had to install webp, but imagemagic needs to be there, of course, and I had that. It still doesn't work on the default terminal on Linux Mint Cinnamon, showing some escape sequences and errors. I'm entering this because I think it would be a good idea to check for the binaries this depends on.

Windows WSL support

While this is likely true, it would be great to see WSL support and maybe someone has figured it out. Thanks

I use a patched rxvt-unicode which support sixel

I use this patch rxvt-unicode-sixel.patch which adds sixel support for rxvt-unicode.

But when I try to use lsix it will silently crash. I do not get a warning or anything. With unpatched rxvt-unicode it will give me a warning that the terminal emulator is not supported but now when it is patched it just silently die.

wsltty: Images are displayed on a single line at the top of the terminal and then disappear

When I use lsix, I would expect the images to display after my current line, and for that display to be persistent. That's not what happens. The images show up at the top of my terminal, one line at a time, "over" the text that exists there, and then disappears, leaving the terminal intact (i.e. it does not replace the text, it just displays the images like an overlay above the text).
Is this due to lsix, or is it due to my terminal?
I'm using wsltty 1.8.4 on Windows 10.

montage: unable to read font ...

When executing lsix this message shows up in the output alongside the thumbnails .

montage: unable to read font `/home/ryuuji/.local/share/fonts/siji.pcf' @ error/annotate.c/RenderFreetype/1468.

The only thing is that I'm not using that font, the one im using is the default from xterm

Terminal not supported - Siduck76's st (sixel branch)

On Ubuntu 21.1, st (Siduck76's version sixel branch), I have used the example command to test my terminal, and it shows the image! After trying to use sixel, the command fails. Any ideas as to why this happens?

Can lsix be used in CentOS7 ?

After installed xterm and ImageMagick, lsix shows nothing about thumnail images. Anything I can do about this?
Thanks!

homebrew cask

please package your code as a homebrew cask and provide installation instructions.

paging support

Is there any way to scroll thumbnails one page at a time? If I try to pipe lsix output through more or less there is just garbage, not too surprising I guess.

Terminal in vim: Error: Your terminal does not appear to support sixel graphics.

If you run :terminal in vim, you get what seems to be a fully-functional terminal, though lsix claims it won't work. echo $TERM reports xterm-256color. I've tested this in xterm where lsix otherwise works.

I get the same issue in guake directly, though that's likely a separate issue.

Supporting terminator?

As described in title

This is fun and i like it!

What's the fastest sixel viewer?

transparent background?

hello and thanks for the project.

is it possible to set the montaged gallery background to transparent color? I tried setting montage "${onerow[@]}" $imoptions -background none gif:- | convert - -background 'rgba(0,0,0,0)' sixel:- but it doesn't seem to work. Does sixel not support viewing transparent background or what could be wrong?

KDE's konsole fully supports sixel and `lsix` starting with version 22.04

Since KDE is widely used and therefore also konsole, maybe it's worth adding it in the docs to the supported terminals.

(solution) Detect dimensions of `foot` running under Sway

When used with foot, window dimensions in lsix can be set as following:

window_width=$(swaymsg -t get_tree | jq -r '.. | (.nodes? // empty)[] | select(.'focused' and .pid) | "\(.rect.width)"')
window_height=$(swaymsg -t get_tree | jq -r '.. | (.nodes? // empty)[] | select(.'focused' and .pid) | "\(.rect.height)"')
width=$window_width

test iTerm2

iTerm2 has now sixel support gnachman/iTerm2@0d0003d.

This script should be checked if it supports this terminal too.

I personally don't have access to an Apple system.

Lsix still not working for me on Fedora, even using `xterm -ti vt340` command.

DECSDM (private mode 80) is interpreted incorrectly

I'm fairly certain that you've got the DECSDM mode backwards. I think it is XTerm that has implemented it incorrectly, and MLterm that has it the right way around. CSI ?80l should enable sixel scrolling, and CSI ?80h should disable it.

Other terminals that match MLterm's behaviour include RLogin (you can see the source here), Tanasinn (see here), and WRQ Reflection (it's a commercial app, but you can see the documentation describing the behaviour of DECSDM here).

I suspect the misunderstanding came about because the VT330/340 manual documented DECSDM the way XTerm has currently implemented it, but I believe that was a mistake. The various VT382 manuals have it the other way around. See here, and here.

The author of Tera Term, who has a collection of DEC terminals, actually tested this on a VT330 and VT382 and reported the results here: https://twitter.com/ttdoda/status/479053314412126208

According to Google translate:

The actual machine and manual of VT382 and the actual machine of VT330 are DECSDM reset and sixel scrolling mode is enabled.

Which I understand to mean that sixel scrolling mode is enabled when DECSDM is reset.

Now I guess it's possible that everyone else is wrong about this, and XTerm is right, but all the evidence appears to point in the other direction.

Get lsix to work on ubuntu terminal?

I downloaded lsix to my /usr/local/bin folder and I'm able to run the command but it returns with gibberish.

http://prntscr.com/fjbkj2

What could I be doing wrong?

lsix stops working when under tmux

(Newbie to lsix/ tmux: I tried searching for tmux and screen before filing this - Please, let me know if this is already discussed)

When I ssh into my box, the terminal identifies itself as xterm and I can run lsix.

However, when I start tmux, lsix seems to stop working. Is it because tmux actually runs a different terminal which does not support sixel or is it just some identification issue? I keep having to step out of tmux to view the image, and then back again. Am I missing something?

And thanks for the program!
