From 3f6ad1bc30570348297ae4aa6d1fd676de229a09 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Thu, 24 Sep 2026 10:06:08 -0300 Subject: Ask from the keyboard which neighbour a closed pane's rows go to Del takes a side: `Del k` gives the closed pane's rows to the nearest expanded pane above it, `Del j` to the one below, each falling back to the other side when it has none. DelAbove and DelBelow are those two lines, with no path of their own under SPC. A bare Del started from a key -- SPC d, Enter on the tag word, a row run from an output buffer -- on a pane with expanded panes both above and below asks instead of guessing. The question is a prompt like Save's or a search's (Pane.Prompt.del_side), so it is painted on the pane's notice band by the same path, and the next key answers it before any mode sees it: k or Up, j or Down, anything else keeps the pane, as does a click. Only a key press sets Pardes.can_ask, so a click, a 9P ctl or event write, a startup line, a restore and a shell exiting all close the pane at once, the rows going where layout.absorbVWeight has always sent them. A collapsed pane is not asked about (it has only a tag row to give), and collapsed neighbours are passed over (layout.expandedNeighbor, which Collapse now uses too). removePane and absorbVWeight take the recipient; every other caller passes null. Three scripts that closed a middle pane with SPC d answer k, which is where the rows went before, and their goldens are unchanged. delask.snap covers the question, Esc, j, a clicked DelBelow and a clicked Del.
