My iTerm2 is configured to show activity, new-output and visual bell in the tab. On Linux I have an approximation for WezTerm.
I have a bell command that I can use in a pipeline or sequence to produce the bell on events I'm interested in. Trivial case is when a program finishes.
I have a fancy alias that can be used in a shell command sequence and which produces different sounds depending on the exit status of the preceding command in addition to sending the terminal bell.
That's what I thought in the beginning. Once I read the spec to the end, it's clear to me that it's overly specific to one use-case — TUI AI agents.
E.g. `kind := permission | question | auth` doesn't make much sense anywhere outside of that use case. The list goes on...
I also found comms around it super muddy, AI agent use case is mentioned but deceivingly watered down with other use-cases.
Overall, that spec is no where close to Kitty/Kovid's level. It's super sad, since mitchellh's work is usually super high quality.
I hope the community will push back and the spec will get better.
There’s always two people at every company who refuse to set up auth automation though, so you end up handling it. They are very stubborn. Even when it trips them up in front of observers while executing an urgent task, I’ve only occasionally convinced them to agree to set up trust instead of typing a password every single time.
Which is to say, I have to support password prompts even though they drive me up the wall.
I actually created a separate golang library with something like this in mind: https://github.com/danudey/ansipants
The original idea I had being that CI environments, or anywhere that shows terminal output, could use a streaming ANSI parsing library to detect when a program sent a 'change window title' OSC event and then start a new collapsable section in its output. This would let programs update the actual terminal window title with its current state when running locally and update the CI interface when running in CI.
Adding in the ability to specify the program's current status and (optionally) progress could be extremely useful in CI environments as well. Imagine, for example, a long-running analysis task which uses OSC 7501 to say that it's currently running and is 75% of the way done. CI could expose that in the UI to provide useful information to the end-user without having to print a progress bar or multiple progress lines to the fake terminal it's being run in.
The thing is when you expect a task to take five minutes, you don’t watch it, you find something else you expect to take five minutes and do that instead. When that ends up taking ten minutes, or when you remember what you were doing before you started, you finally come back around ten minutes later to find that either the task completed four minutes ago, or it failed after ten seconds and you’ve wasted ten now.
The audio was the best out of band notification I had at my disposal 20 years ago.
My first thought when reading this was actually terminal multiplexing however, like screen or tmux. But I’m also always doing the terminal dance because I work on 4 FOSS projects and I keep 1+ terminal open per project so I can jump in and do bug fixes or pull PRs I’ve landed.
I've also never really fully understood why terminfo seems to be a singular package, and not something like man pages where, e.g., each terminal drops in their respectively entry.
