This is cool... one enhancement that doesn't exist currently in any tmux plugins I could ever find is: I often will be in a workflow where I have multiple panes (Typically serial connections), and always wanted a "multi-focus copy mode" I get around this by looping over every pane in the window and copying the last N lines that contain the data I wanted on massaged to show up in the last line or so. This isn't bad, and works out.... but being able to do a multi-focus copy + search + yank would be incredible. I use helix editor so I've gotten into a multi-cursor mindset. #!/usr/bin/env bash
json=${1:-false}
lines=${2:-20}
output=$(
tmux list-panes -F '#{pane_index}:#{pane_id}:#{pane_title}' |
# tmux capture-pane -t "$pane" -p -S "-$lines" | sed '$d'
# tmux capture-pane -t "$pane" -p -S "-$((lines + 1))" -E "-2" | sed '$d'
# done
if $json; then
while IFS=: read -r index pane title; do
historyJson=$(tmux capture-pane -t "$pane" -p -S -56326 |
head -n -1 |
tail -n "$lines" |
jq -R -s 'split("\n") | .[:-1]')
jq -n \
--argjson pane "$index" \
--arg title "$title" \
--argjson history "$historyJson" \
'{
pane: $pane,
title: $title,
history: $history
}'
done |
jq -s .
else
while IFS=: read -r index pane title; do
printf '\n## Pane %s (%s)\n' "$index" "$title"
printf '```bash\n'
tmux capture-pane -t "$pane" -p -S -56326 |
head -n -1 |
tail -n "$lines"
printf '```\n'
done
fi
)
# printf '%s\n' "$output"
printf '%s\n' "$output" | ~/bin/tmux-copy-it |

Oh, I love this idea. A multi-cursor way of pulling output out of several serial consoles at once sounds genuinely useful, and I haven't seen it anywhere either. Your script ports to tuios today with #!/usr/bin/env bash
# Copy the last N lines of every pane on the current workspace, as Markdown.
lines=${1:-20}
tuios list-windows --json |
jq -r '.current_workspace as $ws | .windows[] | select(.workspace == $ws and (.minimized | not)) | "\(.index)\t\(.window_id)\t\(.title)"' |
while IFS=$'\t' read -r index id title; do
printf '\n## Pane %s (%s)\n```\n' "$index" "$title"
tuios capture-pane -w "$id" -S --lines "$lines"
printf '\n```\n'
done
A native version would fit nicely on top of multifocus: open copy mode on the multifocus set, search once across all of those panes, and yank every match (or the last N lines of each pane) into one block with a header per pane. Two questions so I build the right thing:
|
Having it save or go to the clipboard would be a nice option.... and having structured output like markdown / json / txt / none would be nice. Sometimes the data is already structured with an identifier and just printing the lines is fine without any encapsulation. Imagine the following being yanked on multiple panes having it wrapped up in markdown wouldn't be beneficial to the user. But in situations where the pane name has valuable information like the SSH connection information, it could provide useful context for interpreting the results. |

That's a perfect spec, thank you! The LLDP rack example makes the case really well. Here's what I'm building:
I'll post here when it's up for testing. |

:setw synchronize-panescommand. The equivalent feature is Multifocus, which broadcasts your typing to several windows the way tmux's synchronize-panes does (docs/LAYOUT_MODES.md#multifocus).Ctrl+Shift+Clickon a windowCtrl+P→ "Toggle multifocus"Ctrl+P→ "Clear multifocus"To use it:
Ctrl+Shift+Clickeach one, or focus each one and run "Toggle multifocus" from the palette). Windows in the set get a distinct border color.
