Any way to query cursor shape?

[shiro]

I'm working on a simple script that "records" a terminal session (snapshots panes when there's changes) including all ANSI colors.

One issue I ran into was, that the cursor info isn't output by tmux capture-pane, however I managed to get the position using tmux display-message -p -F '#{cursor_x} #{cursor_y}' instead.

The last piece of information I'd need is the cursor shape (block, underline, blinking, etc.). Is there any way to query the cursor shape, through tmux or otherwise (I looked into querying using ANSI sequences, but it looks complicated).

Any pointers are greatly appreciated! 🙇‍♂️

No you would need to add it, it will be similar to for example format_cb_pane_key_mode - you want wp->screen->cstyle. You'll may also need one for wp->screen->mode & MODE_CURSOR_BLINKING and MODE_CURSOR_VERY_VISIBLE.

I'm really happy tmux has the info stored, thanks!
Not sure if I can implement it myself, but I'll try (especially if it's just hooking up existing stuff like you said).

Thanks for the help, made a PR #4414.

One thing that I thought of later on though, would it be possible for tmux capture-pane to also draw the cursor in the output (i.e. enabled by an additional flag argument)?
I think semantically that still makes sense, since you're just capturing the same thing you'd see in a regular terminal window.

Applied the PR now. You could try and make capture-pane include the cursor if you like, I don't know what character you would use for it though? The code is mostly in grid_string_cells in grid.c, although you would need to pass in the cursor from cmd-capture-pane.c.
