Remote Control & Reopen

Two ways to work with a TUI launch from outside it: send console commands from another terminal, and reopen a run after it has ended.

---

Sending commands from another terminal

Every console command except help has a dendros equivalent. Run it in any terminal and the running TUI applies it within about a second, as if you had typed it into its console bar.

dendros focus planner_server
dendros level warn
dendros grep timeout
dendros find exception
dendros mute camera_driver
dendros unmute all
dendros clear
dendros mark sending goal
dendros tee ~/planner.log

dendros focus / find / mark / clear

Command	Same as
dendros focus <node>...	\focus <node>...
dendros level [lvl]	\level [lvl] (no level removes the filter)
dendros grep [text]	\grep [text] (no text removes the filter)
dendros find <text>	\find <text>
dendros mute <node>	\mute <node>
dendros unmute <node\|all>	\unmute <node\|all>
dendros clear	\clear
dendros mark [label]	\mark [label]
dendros tee <file> [-c] [-a]	\tee <file> [-c] [-a] (a relative path is resolved in the terminal you type it in)

Typical use: the launch runs in one pane while you work in another, and you want to look at a single node without switching panes.

Errors (unknown node, no matches) are shown in the TUI's header, not in the terminal that sent the command.

One TUI at a time

Commands aren't addressed to a specific launch. Each command is delivered to exactly one TUI: if several TUI launches are running, whichever one checks first receives it. If none is running, the command is dropped: a newly started TUI launch ignores commands sent before it started.

Reopen the last run

dendros reopen

When a TUI launch ends, DendROS saves its log. dendros reopen opens that log again in the same viewer, so you can keep reading it after you've quit, or after the terminal has been cleared.

dendros reopen

• The header shows which launch it was and when it ended, for example -- last run: my_bringup main.launch.py, ended 14:32 --.
• Scrolling, copying and every console command except mark work as in a live run. Q quits.
• The crash banner from the end of the run is shown again.
• Nodes that were muted when the run ended are still muted. Muting or unmuting during the review is saved, so the next dendros reopen matches.
• The whole log is saved, including lines that were hidden by filters or mutes.

Which run is reopened

Each terminal keeps its own last run: dendros reopen opens the last TUI launch started from the same terminal. Starting a new TUI launch in that terminal replaces it.

Saved runs of terminals that have since been closed are deleted automatically.

A run is only saved if the TUI actually opened. Classic-mode launches and launches whose output was redirected aren't saved.

If there is nothing to reopen, DendROS says so:

dendros reopen

Notes

• A review never receives commands sent with dendros focus, dendros find and so on; those always go to a live launch.
• Saved runs live in ~/.config/dendROS/last_run/.
