A column can be empty, as acme's can; new panes go where acme's makenewwindow puts them

2026-10-01T03:12:15Z

Newcol makes an empty column; closing a column's last pane leaves it empty with the keyboard on its tag; Delcol and Joincol alone take a column away; the session's last pane closing quits. The +New stand-in and replaceStillborn / stillborn_joiner are gone. Every new pane goes through exec.placeNew, which follows acme's makenewwindow (active column, empty column whole, blank space, halving the biggest) or, with Placement pardes, the old rules. ColumnTags is gone: column tags are always shown. A grip drag shows acme's box cursor. Co-Authored-By: Claude Opus 5.5

One Layer for tags, notices, headers and bodies; a taller tag is one layer of rows; wire v8

2026-10-01T03:12:15Z

src/Layer.zig merges TagLayer and BodyLayer. `rows` (0 = no layer) and a cursor at {x, y}. A tag of N rows is ONE layer of N grid rows: tagHit answers the row as `line`, bodyHit keeps its meaning, and the per-line layer bases (TAG_LINE_LAYER_BASE, HEADER_LINE_LAYER_BASE) are gone, not aliased. Wire v8, the one bump: tag layers carry rows and cursor y, and the frame carries the placed region list. v7 and v9 peers are refused in both directions (server test over both, a new frontend test over both). web: tag_layer_value 11 = rows, 12 = cursor y; app.mjs lays every row. macOS: the Zig side compiles against Layer; pardes.h still sees one row per tag layer (accepted, the macOS shell is ignored for now). No visual change: snapshot goldens and the 17 GUI goldens byte-identical. Shared files touched: pardes.zig, Messages.zig, gui.zig, macos.zig, detached/client.zig, detached/server.zig, detached/wire.zig (plus web.zig, app.mjs, edit.zig, look.zig). Not touched: mouse.zig, tagline.zig, colors.zig, tty.zig, dump.zig, exec.zig, host_io.zig, panes.zig.

File the tag code into tagline.zig and draw tags beside bodies

2026-10-01T03:12:14Z

With tags reduced to Texts, what is left of them is the computed prefix, the default and saved tails, entering and leaving a tag and the headers: that goes to tagline.zig, as acme keeps the tag half of a window in wind.c. Tag and header drawing moves next to body drawing in body_layer.zig, and the tag hit helpers go to tag_layer.zig with the Hit they read, where sameCell now also tells the lines of a taller tag apart. The docs describe the tag as a Text. Co-Authored-By: Claude Opus 5.5

Make the column and workspace tags Texts with the pane tag's keys

2026-10-01T03:12:14Z

The headers had their own one-line editor with its own keys: Enter always executed, h/l and J/K moved between headers and panes, Ctrl-c/x/v cut and pasted, and TagLine refused a newline that 9P accepted. They are now Texts like a pane's tag, with no prefix and a default until edited, so normal and insert mode, undo and the look and execute keys are the body's. Moving between them is the window keys' job: Up from a pane with nothing above it reaches its column's tag and then the workspace's, Down comes back, and Left and Right walk the column tags.

Light a held column grip, and rail its landing beside the rule where the GUI shows it

2026-10-01T03:12:14Z

The column grip worked in the GUI but showed nothing anyone could see. Driving the real SDL window with pixel mouse events, press, drag and release all reach the core and reorder or resize the column; the feedback is what failed. The grip kept its muted color while held, and a reorder's insertion rail was drawn in the gutter cell at the destination edge. The GUI paints that cell as the column's scroll rail, and at the window's left edge, the common case of moving the right column first, the dashes were lost in it. From the leftmost column, a drag short of a neighbour's middle shows no rail, rightly, since nothing would move, but nothing said the grip was even held. A held grip now lights in column_box, the accent its muted color is mixed from, and the rail takes that color. The rail runs in the seam cell left of where the column's rule will land, where a border drag's rail runs, for a reorder and a left-edge move alike; at the window's left edge, which has no seam, it runs just past the scroll rail, leaving column 0's grip and pane boxes whole. A carried column's pointer aims at a place, not a word, so the column tags no longer light the word under it, and a release snaps the layout as a border drag's does rather than animating it. The preview and the release both ask layout.columnDrop where the column goes, so the rail stands where the release puts the edge, and the drag no longer carries its unused column index.

Center tagline bands, frame anchors evenly, fill to the window edge, and resize columns from their grip

2026-10-01T03:12:14Z

Every tag band (workspace, column, pane) is centred in its row, so text sits at one baseline offset. Anchors are inset from the column rule by that same margin, so they are square and the band frames them on the left, top and bottom; the pane mark moves to stay centred. When the window is not a whole number of cells, the bands, rules, spines and scroll thumbs at the right and bottom edges run on through the leftover pixels. A column grip dropped short of another column's place now moves the column's left edge, with a dashed rail preview, sharing setColumnPairWidth with the border drag. A release still on the grip changes nothing, and a pair too narrow for two MINW columns is left alone. PARDES_TEST_PAD adds leftover pixels to a test-mode window and capture.
