Hello OSC 7501

The exciting news in this release is support for the brand new Program Status Protocol, otherwise known as OSC 7501, released just a few days ago. The protocol is designed to allow terminal applications to report what they're doing (e.g. idle, working, waiting on the user, finished, or failed) and why.

The obvious case for the design is AI agents, but are lots of other use cases for this, and we’re excited to see what you build with it.

It’s subtle, but here’s Crush in Superlogical’s Rex with the feature integrated (notice the dot in the first tab).

Bugfixes

Also, this release brings some very important fixes done by @AdamMagued, @simpleqt and @GreedyC.

Cheers!
Charm 🌞

This is a small change to programs with no WithInput. Removed capability queries, which resulted in leaking of raw ANSI escape sequences.

Keybinds missing!

MouseButton11 and media record buttons were improperly handled, now fixed! (thanks to @Ricardo-M-L and @bunlongheng)

Weird UI artifacts with some terminals 👽

Graphemes, schmraphemes

No terminal can render emojis perfectly, but we can try. This release improves some very specific edge cases around emoji rendering. Enjoy!

A few lil’ stability patches

Hi! This is a patch release with a few solid improvements around stability and correctness.

• @lrstanley, one of our faves, fixed a race condition around mice in the Cursed Renderer
• @lawrence3699 fixed a panic that could happen when input's not available
• We fixed a correctness issue with regard to mouse releases when Kitty Keyboard was active (thanks, @mitchellh)

Thanks for using Bubble Tea, and if you see anything awry please do let us know!

This release fixes an issue with how Bubble Tea handled wide characters. Before, a wide character might be skipped or cause an infinite loop causing the CPU to spike. See fdcd0cf and charmbracelet/ultraviolet#109 for more details.

Extra Extra Extended Keyboard Enhancements!

This release adds support for the full set of Keyboard Enhancements. Now you can enable any enhancements on top of the default disambiguate one.

func (m model) View() tea.View {
  var v tea.View
  v.KeyboardEnhancements.ReportAlternateKeys = true
  v.KeyboardEnhancements.ReportAllKeysAsEscapeCodes = true
  return v
}

Smarter Renderer

We also fixed a few renderer related bugs and made the Cursed Renderer smarter. Now, we always reset the terminal tab stops for the Bubble Tea program process context. People using tabs -N in their shell profiles shouldn't be affected.

See the full changelog below.
