The screenshot was creating a new pyte screen with arbitrary dimensions
from query params, but the replay buffer contains ANSI sequences meant
for the session's actual terminal size. This mismatch caused wrapping.
Now we use get_screen_state() which returns the actual screen buffer
from the terminal session's pyte screen, with the correct dimensions.
This ensures the screenshot matches exactly what the terminal rendered.
Test fixes:
- Fix app_session.py to use 'textual-webterm' package name (not 'textual-web')
- Fix CLI version test to not hardcode version number
- Fix static path test to not use removed Path._flavour attribute
Removed unused dependencies:
- xdg
- msgpack
- httpx
All 209 tests pass with 86% coverage.
Screenshots now properly preserve terminal colors:
1. Replay buffer provides raw ANSI data with color codes
2. pyte interprets escape sequences for accurate screen state
3. Rich renders the pyte buffer with colors to SVG
This gives us both accurate terminal state (no creeping/wrapping)
and proper color preservation in screenshots.
Bumps version to 0.1.12.
Instead of trying to replay a truncated byte buffer through pyte, this
change maintains a pyte Screen object within TerminalSession that gets
updated as terminal data flows through. This provides accurate terminal
state for screenshots without issues from buffer truncation.
Key changes:
- Add pyte Screen and Stream to TerminalSession
- Update screen state as data arrives via _update_screen()
- Add get_screen_lines() to return current screen state
- Resize pyte screen when terminal size changes
- Update local_server to use get_screen_lines() directly
- Remove _apply_carriage_returns() workaround
This properly fixes the tmux status bar 'creeping up' issue by ensuring
the screenshot always reflects the actual terminal state.
Replaces simple carriage return handling with pyte terminal emulator
to properly interpret all ANSI escape sequences including cursor
positioning. This fixes the tmux status bar 'creeping up' issue in
screenshots.
Adds pyte dependency to pyproject.toml.
Resolves TODO item #2.
