sixel-tmux VS kitty

It's not really that strange that tmux doesn't support sixels. It's quite a bit more complicated and resource-intensive than ANSI Escape Codes or ncurses.

It might be fine for local[1] multiplexing but over the network it is not as fast as even something like VNC or RDP.

After having spent too much time trying to get the simple https://github.com/csdvrx/sixel-tmux/ features into mainline tmux (last November https://github.com/tmux/tmux/issues/3753), maybe it'd be easier to jump ship as use zellij?

Could anyone offer recommendations on "riced" zellij configuations, or just a demo where it shows doing with (say charts of disk usage per folder), watching a movie with mpv + keeping a vim to type on?

Your approach looks very sound!

A fork of terminfo may be needed if the description of modern terminal capabilities can't be added -- or if old and deprecated attributes repurposed for that job (like in your padding example): if you're automating the correction/creation of terminfos in ~/, IMHO, it may be better to piggyback on tic as much as possible.

Anyway, to backport modern terminal descriptions to legacy programs, creating correct binary terminfos in ~/.terminfo seems the best practice. You can also invent new TERM. When I wanted to have italics etc about everywhere, personally that's just what I did for sixel-tmux: https://github.com/csdvrx/sixel-tmux/?tab=readme-ov-file#ste... : just declare a new $TERM you know to be right, and use that in the apps that let you use a little logic in their configuration file

I do that in my .vimrc:

   " If Vim doesn't know the escape codes to switch to italic

You can have that functionality integrated within tmux with https://github.com/csdvrx/sixel-tmux/ : if you terminal doesn't support sixels, you'll at least see something close to the picture they represent.

Then of course it's not pixel-perfect unless you make your terminal very large (like 800x240 instead of 80x24) but something being better than nothing, I'd argue it's for the better if all you can do is 80x24 with no pictures otherwise.

sixel-tmux can help you have both: https://github.com/csdvrx/sixel-tmux/

> It's 2021, and we should be able to do litterate programming in the console, with full graphical support.

Yeah. We are stuck cosplaying computers from the sixties.

What's even funnier, even if you find a modern terminal emulator that supports features like ligatures, graphics, emoji etc. you still will be blocked by tmux. Sure - not everyone needs tmux. If you never work on remote machines, you can live without it.

But I work on remote machines all the time. I also use Kakoune text editor that defers window management to external tools (WM or tmux, but to be honest, tmux is much better). Zellij is more of r/unixporn bait than usable tool for now. So I'm stuck with text only interface.

> Some terminal emulators have support for images, which fit most of the use cases here but not the one I described.

That what sixel-tmux is for, when you're in a hurry and needs images with your current terminal emulator: https://github.com/csdvrx/sixel-tmux

Maybe tmux-sixel does that tmux sixel

If you want some crazy shit like sixels or italics and ligatures, try msys2 that's what I've used for the screenshot. The only thing comparable on Linux in term of features is xterm and, that's another story.

And kitty is much faster according to this: https://github.com/kovidgoyal/kitty/issues/2701#issuecomment...

Also typometer based measurements also on Linux. Shrug.

kitty (Linux & Macos)

A terminal with built-in telemetry and a pricing model... Just what I never wanted!

To avoid being too negative, I'll offer the option of Kitty[1]. My current favorite terminal. Supports many features.

Including my personal favorites:

* ctrl+c (as opposed to stupid things like ctrl+shift+c) to copy data only when you have content selected. Otherwise, ctrl+c sends a sigint like normal.

* font ligature support (a controversial feature)

The ncurses/xterm maintainer also had quite a lot of friction with the developer of the kitty terminal emulator.

IME, this is like the golden age of terminal apps in general and macOS-compatible ones in particular. There are several really good terminals for macOS:

[iTerm2 app](https://iterm2.com/)

[Kitty terminal](https://sw.kovidgoyal.net/kitty/)

[WezTerm terminal](https://wezfurlong.org/wezterm/index.html)

[Alacritty](https://github.com/alacritty/alacritty)

My daily driver is WezTerm…

- Runs on Linux, macOS, Windows 10 and FreeBSD

- [Multiplex terminal panes, tabs and windows on local and remote hosts, with native mouse and scrollback](https://wezfurlong.org/wezterm/multiplexing.html)

- [Ligatures](https://github.com/tonsky/FiraCode#fira-code-monospaced-font...), Color Emoji and font fallback, with true color and [dynamic color schemes](https://wezfurlong.org/wezterm/config/appearance.html#colors).

- [Hyperlinks](https://wezfurlong.org/wezterm/hyperlinks.html)

- [Searchable Scrollback](https://wezfurlong.org/wezterm/scrollback.html) (use mouse wheel and `Shift-PageUp` and `Shift PageDown` to navigate, Ctrl-Shift-F to activate search mode)

- xterm style selection of text with mouse; paste selection via `Shift-Insert` (bracketed paste is supported!)

- SGR style mouse reporting (works in vim and tmux)

- Render underline, double-underline, italic, bold, strikethrough (most other terminal emulators do not support as many render attributes)

- Configuration via a [configuration file](https://wezfurlong.org/wezterm/config/files.html) with hot reloading

- Multiple Windows (Hotkey: `Super-N`)

- Splits/Panes (Split horizontally/vertically: `Ctrl-Shift-Alt-%` and `Ctrl-Shift-Alt-"`, move between panes: `Ctrl-Shift-ArrowKey`)

- Tabs (Hotkey: `Super-T`, next/prev: `Super-Shift-[` and `Super-Shift-]`, go-to: `Super-[1-9]`)

- [SSH client with native tabs](https://wezfurlong.org/wezterm/ssh.html)

- [Connect to serial ports for embedded/Arduino work](https://wezfurlong.org/wezterm/serial.html)

- Connect to a local multiplexer server over unix domain sockets

- Connect to a remote multiplexer using SSH or TLS over TCP/IP

- iTerm2 compatible image protocol support, and built-in [imgcat command](https://wezfurlong.org/wezterm/imgcat.html)

- Kitty graphics support

- Sixel graphics support (experimental: starting in `20200620-160318-e00b076c`)

While researching how to fix the issue I found this GitHub issue with the fun number 606 (almost 666). First, I should say, that there is no easy solution. Shortly you have to specify for each shortcut mapping alternative with your keyboard layout. That means, for example, if your keyboard has Cyrillic "м" instead of Latin "v" then for making work CMD+V you should add also into configuration an additional line with "м".

I haven’t tried this yet (so please take my commentary with a grain of salt), but my initial thoughts are: (1) it looks interesting, (2) it looks overwhelming (there’s a lot going on in those screenshots), and (3) it’s likely slow (I might be completely wrong).

To elaborate a bit…

1. I love good design work and well-designed (UI-wise) software, and it certainly looks like the creators of Wave Terminal have made that a priority.

2. UX-wise, there’s just too much going on. As someone who lives in my terminal (with the exception of browsing the web, I do virtually everything in my terminal), it’s the single most important piece of software on my computer and it can never get in my way. I used the same terminal for many years and only switched to kitty [0] a couple years ago after testing it for months. In all of those years, every single terminal I tested managed to get in my way. Somehow, kitty manages to be packed full of features without ever—not even once—getting in my way, being slow, or freezing up on me.

3. Generally speaking, I think building on open web standards is a great thing and a plus. Unfortunately though, even in 2023, my experience has been that it’s really hard to build performant software meant to be run on native platforms using web technologies; the few who get this right—e.g., Figma—are anomalies and they generally invest an enormous amount of time and engineering capital into squeezing out as much performance as possible. As I explained in #2, for something as critical as my terminal, not being performant is simply not an option, so as much as I love the idea of building on open web standards, it actually scares me for software like this.

That said, I’m obviously judging before trying here, so I’ll make some time to test Wave Terminal.

to solve this I run Kitty with a tab bar on the bottom. this has tons of inspo: https://github.com/kovidgoyal/kitty/discussions/4447

Those existing tools are poorly designed, if you read the article it has a link to the discussion about its design choices, which contains in turn discussion about all the problems with sixel https://github.com/kovidgoyal/kitty/issues/33#issuecomment-2...
