upterm VS Extraterm

The reason you don’t see a feature like blocks (with the exception of Upterm) in most other terminals is because the terminal has no concept of what program is running, or really of anything that’s happening within the shell. At a high level, a terminal reads and writes bytes from a pseudoterminal to interact with the shell. This technology is very antiquated--the shell essentially thinks it is interacting with a... - Source: dev.to / about 2 years ago

Suprised that no one has mentioned this, but upterm seems to be exactly what you're describing--a terminal emulator that shows a drop-down list of suggestions with explanations. Sadly, only a few commands are supported, and it's no longer being worked on. Source: over 2 years ago

Currently haven't gone as far as making some kind of dedicated shell component though. I find it important that normal shells can work fine with in Extraterm. There was a project from a few years back which also mashed GUI/emulator together with the shell side, Upterm. SSH and containers tend to be the natural enemy of having your own shell though.

TermKit was one of the inspirations for Extraterm ( https://extraterm.org/ ). It separates command output, allows for reuse of previous output, as well mixing content types. The terminal VSCode has been picking up on these kinds of features lately. Now they can even "sticky" the previous command line at the top of the window when scrolling through long output. It has taken a long time, but these ideas are slowing... - Source: Hacker News / 5 months ago

Extraterm is very similar in style to what you are asking. I recommend the Qt version. Source: about 1 year ago

iTerm2 is a great piece of software. It is probably the best "featureful" terminal on any platform. It is also an influence on my terminal project which also has a "features are good" philosophy but isn't limited to macOS. (https://extraterm.org/ , the website needs an update. It doesn't show latest state of the Qt version.). Source: about 1 year ago

My terminal, Extraterm used to have some direct text editing in older versions before changed the whole UI to use Qt and generally be much much faster. Source: over 1 year ago

There aren't many terminals on Linux much are aiming at iTerm2. At lot of popular terminals follow a minimalist philosophy where features are considered frivolous and a sign of newbie-ness. Personally, I'm not into that which is why I continue to work on my own terminal Extraterm with a maximalist approach. Iterm2 is a great piece of software and something I take a degree of inspiration from. Source: almost 2 years ago
