Log viewer

The viewer opens a persistent paramiko channel and runs tail -n 50 -f <log_path> on the remote host. Lines are streamed into a RichLog widget in chunks.

Note

The in-memory buffer is capped at 20 000 lines to keep memory bounded on long-running jobs — older lines are evicted as new ones arrive. Search and yank operate on what’s in the buffer; lines that have already been evicted won’t match.

The header bar reflects the current mode:

• FOLLOW — auto-scrolls to keep the bottom in view.

• PAUSED — manual scrolling; new lines still arrive but the cursor stays put.

Search

Press / to open the search bar:

Matching is case-insensitive substring against the in-memory buffer. The bar shows a running match count. Use n / N to jump between matches; jumping a match pauses auto-follow so the screen doesn’t immediately scroll away.

Save & yank

Key	Action
w	Save the buffer to ~/Downloads/<jobid>_<stream>.log (falls back to $HOME if Downloads is missing).
y	Copy the current match (or the most recent line) to the clipboard via OSC 52 (see Job table).

All keybindings

Key	Action
f	Toggle FOLLOW / PAUSED.
/	Open the search bar.
n / N	Jump to next / previous match.
w	Save the buffer to disk.
y	Copy the current line to the clipboard.
j / k / g / G	Scroll.
Esc / q	Close the viewer (also closes the SSH channel).
