Well-written article! I wish there was some kind of standard to tell CLI apps what features to expect from the system pager, so they can act accordingly … Right now, apps can talk to the terminal to check for feature support, but all of that falls apart when the output is piped to a pager. (Do we support inline links? ANSI colors? Sixel support??) Shameless plug, specifically regarding Sixel support: I needed a pager…

To be pedantic, you mean a standard like IEEE 1003 aka POSIX? (https://pubs.opengroup.org/onlinepubs/9799919799/utilities/m...)

I wrote streampager a few years ago to scratch a similar itch. It works well enough for my own uses (and is/was used in library form as the built-in pager for sapling and jj).

I think it still needs some work for more general use which I unfortunately don't have time for at the moment.

I am definitely waiting for a "modern less replacement" in the same vein as fd, sd, fzf, and the rest of the under-20yo cli crew. I get that "less" is reasonably maintained still. I think the killer feature for me would be refresh. I get that this can't work for piped input, but I want `git diff` to show in a pager with a refresh button that holds my place. fzf supports both refresh and piped input, so perhaps there'…

I've noticed that subconsciously, I've started to use `bat` for interactive paging, even though that's not its main use case

Bat just uses less internally. And it deliberately breaks less’ handling of ^C, annoyingly.

Author here! If I were to give this post a longer title, it would be "I made a terminal pager because I needed a really good viewport component for my Go TUIs, then realized that a TUI viewport is just a mini terminal pager and I want the same text navigation and manipulation experience everywhere that I encounter long text blocks in my terminal". I take no issue at all with `less`, it's super powerful and configurab…

"Because I felt like it" is also a perfectly acceptable answer ;-)

Slightly related: I am an Arab who speaks Arabic and reads Arabic and the only place I ever see the unicode character ﷽ is by programmers giving an example of "unicode is too hard".

Perhaps as a graphical element at the beginning of books, too.

It is a part of the Arabic Presentation Forms block which explicitly is for supporting legacy encodings and should not be used.

The whole phrase is one character?

can you give an example of what you mean and how you might expect it to be achieved with a reloaded diff? otherwise `while true; git diff --color=always |less -r; done` gets you most of the way to what you are asking for

Realistically, I will be reviewing a diff, see a hunk I don’t like, change it, and want to see the change back in less. So saving my scroll offset would accomplish my goal. I guess I should add that I want to be able to quit as well?

Like I said, fzf does this. Bind a key to an action that effectively changes the file from stdin to a different command that it runs, while preserving view state.
