When I have a lot of buffers open and I use helm-mini to look through them, I notice that deeply-nested or tramp buffers take up too much horizontal space, causing them to wrap around, like this:

buffer-wraparound

How can I get helm to truncate these lines so they don't wrap around? Toggling truncate-lines when the helm buffer is open doesn't take effect.

The relevant setting is helm-buffers-truncate-lines which truncates lines when non-nil. You can use M-x customize-variable helm-buffers-truncate-lines to toggle it.

As for now. You can use:

0

as of now, it is still bound to C-] however the name of the function has been changed to helm-toggle-buffers-details. Another function that can be relevant is C-c > bound to helm-toggle-truncate-line. Another useful keybinding to adjust mini-buffer height is C-} or C-{.
