From e7c181d6238dae4b08a02c1a9828917c2497f89d Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 14:20:56 -0300 Subject: A command line runs as its own command pane unless it is clicked at a shell's prompt A middle click, an exec write or a tag word that no builtin knows was typed into some terminal for the pane's directory, sharing whatever state that shell was in and answering nothing, so a misspelling vanished into a shell. Now only a line clicked at an interactive terminal's prompt is typed there. From anywhere else it runs as a command pane: a terminal whose child is $SHELL -c the line in the pane's directory, full emulation, which shows its output and then exit N from the host's reaping of the child, and stays. A finished command pane is the next command's for its directory, which runs below what it showed after a '% line' line (acme appends to +Errors and never clears it, util.c:213); a running one gets a second pane. Kill ends a command pane's whole process group, the log records run and exit, exec reads back the command pane's serial, and a line is at most 1 KB, read off the pane as the host forks rather than carried in every spawn effect. ttyForDir's search for a free shell is gone. The goldens of chordcut, cmdword and layout-open change where a file's exec now opens a command pane, and ttytaken is rewritten to exec from the terminal itself; docs/open-questions.md records the decision.
