a Node.js instance) has no idea that scrolling has been limited to a particular region. The restrictions (no cursor movement commands allowed, no resizing) are required because the program that is generating the output (e.g. You could use this command to limit the scrolling region to the top (or bottom) N-1 lines of the terminal and write some sort of instance-identifying text into the non-scrolling line. Like many terminal emulators, tmux supports a “set scrolling region” terminal control command in its panes. you do not resize the panes while your programs are running.your programs ( Node.js instances) have limited terminal interactions with the panes in which they are running (i.e.There is, however, a light-weight solution as long as Sure, there is a lot of other functionality wrapped around the terminal emulator, but you would need a large chunk of terminal emulation code just to provide a reliable status line. Programs like tmux and screen are just such terminal re-emulators. If the cursor is on the next to last line, then scroll this line and all the lines above it up one line, to provide a clear next-to-last line (protecting the status line on the last line). Likewise, an LF sent to the inner terminal must become When translated for and sent to the outer terminal. Sent to the inner terminal must be become For example, to maintain a status line at the bottom of the outer terminal, the command Such (re)emulation is needed to translate control sequences sent to the inner terminal and translate them for the original terminal. In the general case, to provide an inviolate status line on some given terminal, you will need a full terminal (re)emulator that sits between the original terminal and a new terminal (one with one fewer lines). If you absolutely need a dedicated line to display some per-pane information, then nested tmux sessions may not be as much (unnecessary) “overkill” as you might first think. Just send the appropriate title-setting escape sequence before starting the main command for each pane. willing to switch panes to see the title of an inactive pane), you can get by with the default functionality. So, as long as you are satisfied with being able to see the active pane’s title (i.e. By default the active pane’s title is displayed on the right side of the tmux status line (the default global value of the session variable status-right is "#22T" %H:%M %d-%b-%y, which shows 22 characters of the pane’s title, the time, and the date). You could do this from the shell like this: printf '\033]2 %s\033\\' 'title goes here'Įach pane’s title defaults to the system’s hostname. see the section called Names and Titles in the tmux manpage). You can set a pane’s title with the escape sequence ESC ]2 … ESC \ (e.g. Tmux does support per-pane titles, but it does not provide a per-pane location to display these titles.
