Adds kittens/remote_file/main.go (ask menu, hostname-mismatch prompt,
save-path prompt with tab completion, edit/open/save actions) on top of the
ControlMaster/ssh helpers from the previous two commits, registers it in
tools/cmd/tool/main.go, and adds remote_file to shell-integration/ssh/kitty's
wrapped_kittens list so both `kitty +kitten remote_file` and ssh-session
invocations exec the Go binary directly. main.py is shrunk to option_text
(kept importable by kitty/cli_stub.py and used for --doc/--help generation),
is_ssh_kitten_sentinel (kept importable by kitty/window.py), and the
handle_result shim boss.py runs in-process to open the returned file.
Also drops the dead `-h` alias on --hostname: Python's CLI layer always
special-cases -h/--help ahead of user options, so it never worked as a
hostname shorthand, but the Go CLI layer hard-errors on the collision; removing
it is a no-op for existing behavior (boss.py only ever passes --hostname) and
unblocks `kitten remote-file --help`. Also adds the same reset_terminal()
calls Python makes between UI phases (ask menu -> action, hostname-mismatch
prompt, overwrite prompt, $EDITOR handoff) so the Go and Python screens match.
Manually verified parity against Python (ask menu, cancel, open/edit/save
download+upload round-trips, hostname-mismatch Y/N, save-path prompt and
overwrite O/A/R/N) using a fake-ssh test double, and confirmed post-wrap that
`kitty +kitten remote_file` execs the Go kitten binary.
- Python (kitty/launch.py): Track editor PID via monitor_pid to capture
exit code when editor window closes. Send exit code as data in the DONE
message instead of sending no data.
- Go (tools/cmd/edit_in_kitty/main.go): Parse exit code from DONE message
data and use lp.Quit(exit_code) to exit with the editor's exit code.
- Go (tools/cmd/tool/confirm_and_run_shebang.go): Check exit code when
running edit-in-kitty as a subprocess; abort execution on editor failure.
Add a Go-based command_palette kitten that provides a searchable,
interactive overlay for browsing and triggering keyboard shortcuts
and actions.
- New Go kitten at kittens/command_palette/ with FZF fuzzy search,
grouped/flat views, and remote control action triggering
- Python collect_keys_data() does data collection, passed via stdin
- Navigation: arrows, ctrl+j/k (vim), ctrl+n/p (emacs), page up/down
- Enter triggers the selected action via RC command
- Help text displayed in footer for selected binding
- Added Go tests (main_test.go) and Python tests (command_palette.py)
