rlwrap VS contour

Possibly more universal, but there are also tools like rlwrap [1] that adds readline support to programs that don't have it. From the docs apparently the readline library ships a similar tool ootb nowadays but I haven't tried that and just noticed now when I wanted to share the rlwrap link.

Otherwise I use rlwrap, which is a general purpose readline wrapper: https://github.com/hanslub42/rlwrap It's pretty basic stuff, but makes basic line editing less painful, & adds history support.

Friends if you dont know: you can add readline support to LOTS of things, especially custom scripts and tools with a prompt by just calling the program with rlwrap.

rlwrap for any interactive command will give it a history. You can even build a file to have tab completion. https://github.com/hanslub42/rlwrap

rlwrap is a 'readline wrapper', a small utility that uses the GNU Readline library to allow the editing of keyboard input for any command, something that tclsh, wish and sbcl don't provide.

This can be as easy as wrapping a simple stdin/stdout loop with rlwrap, all the way to using full featured TUI libraries like bubbletea (golang), textual (python) or imtui (c++).

You could always use rlwrap (installable via homebrew). You would launch R with rlwrap R in that case. However, I suspect there is something else missing, because it appears that the R repl usually includes readline support. Thus my questions about installation method and OS.

As you can see ,clj, behind the scenes, wraps a call to $bin_dir/clojure with the rlwrap tool. rlwrap provides a better command-line editing experience.

If read-line functionality is missing from languages that provide repls or command line interpreters, rlwrap has always served me well on linux. Many distros provide their own package too.

Another problem is that the cursor moves while the screen is buffer is being rendered. The location is only really known once the cursor settles in the same place for some time, which is unacceptable in terms of latency.

The synchronized output extension could be used to do this, though. https://github.com/contour-terminal/contour/blob/master/docs...

This apparently does not support the Kitty graphics protocol, just Sixel, which makes it look fairly unattractive to me, personally.

contour : a terminal application

https://github.com/contour-terminal/contour Contour has a implementation for this. See this release: https://github.com/contour-terminal/contour/releases/tag/v0.3.6.240

Now that I'm well rested I decided to compile some similar terminal emulators with clang++ and rustc to see how big of a gap we're looking at. For the C++ terminal emulator I compiled contour with ~80k lines of C++ and over 200k lines when accounting for dependencies (not including dynamically linked dependencies), and then I'm using alacritty with ~35k lines of Rust and over 2 million (!) lines for the whole dependency tree when vendoring all dependencies. Because Rust tries to make most software cross platform with conditional compilation and many of these aren't Linux specific libraries I'm gonna assume it's compiling half or two thirds of the lines of dependencies for this experiment with the C++ compiling probably 3/4ths of the dependency tree considering I'm not on windows.

I have my eyes on this though.
