Working on bug fixes and UX. Streams restarting, fixed lots of bugs,
timing issues, concurrency bugs. Get status shipped to the FE to drive
"shield" state display. Deal with stale streams.
Also big UX changes to the block headers. Specialize the terminal
headers to prioritize the connection (sense of place), remove old
terminal icon and word "Terminal" from the header. Also drop "Web" and
"Preview" labels on web/preview blocks.
Added `wsh focusblock` command.
Handle both types of paste data. Write utility functions to normalize
paste events to {text; image}[]. Fix duplication issue (call
preventDefault() early). Handle multiple image pasting (by adding a
slight delay). Convert Ctrl:Shift:v to use a *native paste* which allows
capturing of images!
* add automatic OSC 7 support to bash and zsh
* add new wave OSC 16162 (planck length) to get up-to-date shell
information into blockrtinfo. currently implemented only for zsh. bash
will not support as rich of data as zsh, but we'll be able to do some.
* new rtinfo will be used to provide better context for AI in the
future, and to make sure AI is running safe commands.
* added a small local machine description to tab context (so AI knows
we're running on MacOS, Linux, or Windows)
Massive PR, over 13k LOC updated, 128 commits to implement the first pass at the new Wave AI panel. Two backend adapters (OpenAI and Anthropic), layout changes to support the panel, keyboard shortcuts, and a huge focus/layout change to integrate the panel seamlessly into the UI.
Also fixes some small issues found during the Wave AI journey (zoom fixes, documentation, more scss removal, circular dependency issues, settings, etc)
The current layout system uses a complex bidirectional atom architecture
that forces every layout change to round-trip through the backend
WaveObject, even though **the backend never reads this data** - it only
queues actions via `PendingBackendActions`. By switching to a "write
cache" pattern where local atoms are the source of truth and backend
writes are fire-and-forget, we can eliminate ~70% of the complexity
while maintaining full persistence.
----
Every layout change (split, close, focus, magnify) currently follows
this flow:
```
User action
↓
treeReducer() mutates layoutState
↓
layoutState.generation++ ← Only purpose: trigger the write
↓
Bidirectional atom setter (checks generation)
↓
Write to WaveObject {rootnode, focusednodeid, magnifiednodeid}
↓
WaveObject update notification
↓
Bidirectional atom getter runs
↓
ALL dependent atoms recalculate (every isFocused, etc.)
↓
React re-renders with updated state
```
---
## Proposed "Write Cache" Architecture
### Core Concept
```
User action
↓
Update LOCAL atom (immediate, synchronous)
↓
React re-renders (single tick, all atoms see new state)
↓
[async, fire-and-forget] Persist to WaveObject
```
### Key Principles
1. **Local atoms are source of truth** during runtime
2. **WaveObject is persistence layer** only (read on init, write async)
3. **Backend actions still work** via `PendingBackendActions`
4. **No generation tracking needed** (no need to trigger writes)
Working on AI SDK compatible backends for OpenAI and Anthropic. Thinking + ToolUse etc. For use with AI SDK useChat on frontend. Still needs more testing, WIP, but this is a good start. Want to get this committed to so I can work on more integrations.
