Earlier quoted context omitted.

I'd love to try out Linux again. Is the rMBP story any better than it was in 2014? Last I heard there were way too many driver problems.

iTerm2 now supports Metal for GPU-based rendering by default (when you aren't on battery). It's now blazingly fast all of the time.

I think iterm2 doesn't support ligatures when using metal.

Which is odd, cause Kitty does, IIUC.

I've been using Kitty for a month now. I really like it. It's slightly less usable out of the box than iTerm 2. The default shortcuts are very counterintuitive (no CMD T for new tab or CMD W to close tab). But editing the preferences is straightforward.

I prefer it to iTerm because it's so. Damn. Fast. It's the only software (besides Sublime) I run on my laptop that actually feels like it's using the 40 years of transistor improvements I'm paying for.

I know iTerm recently added a Metal renderer but I need ligature support, which iTerm Metal doesn't have.

Maintainer has also been responsive on GitHub.

What I could really use would be a terminal emulator that is: a library that I can feed data directly into (without a pty) LGPL, MIT, or BSD able to quickly serialize its internal state (make me a blob) able to restore state if I feed it a blob of saved state, even across different software builds portable to recent versions of Linux and Windows

tcl.tk ?

That's what I was thinking, it sounds like the wish terminal.

Gpu powered terminal emulator? This performs almost 100x worse than Mac OS Terminal.app. Cat-ting a long file takes 100x longer to draw on the screen! Isn’t it supposed to be faster if it’s “GPU powered”?

what is the benefit of using a GPU powered terminal on my Integraded 6000 ? rather than my iterm2 ?

I thought macOS was already GPU accelerated with Quartz? And wouldn't Windows be doing something similar by now? The CPU is certainly not writing pixels directly out to VESA buffers in 2018, right?

That sounds interesting! Out of curiosity, what is your use case for those features?

It is useful for backwards execution. This is supported in various ways by Simics, gdb, SID simulator, rr, the Moxielogic emulator, and others.

It is useful for virtual machine snapshots. You can restore the virtual machine with the terminal state intact.
